Announcing the Bytecode Alliance: Building a secure by default, composable future for WebAssembly by Lin Clark
Today we announce the formation of the Bytecode Alliance, a new industry partnership coming together to forge WebAssembly’s outside-the-browser future by collaborating on implementing standards and proposing new ones. Our founding members are Mozilla, Fastly, Intel, and Red Hat, and we’re looking forward to welcoming many more.
Getting Started with Rust and Apache Kafka by Gerard Klijs
I’ve written an event sourcing bank simulation in Clojure (a lisp build for Java virtual machines or JVMs) called open-bank-mark, which you are welcome to read about in my previous blog post explaining the story behind this open source example. As a next step, specifically for this article I’ve added SSL and combined some topics together, using the subject name strategy option of Confluent Schema Registry, making it more production like, adding security, and making it possible to put multiple kinds of commands on one topic. We will examine how the application works, and what was needed to change one of the components from Clojure to Rust. We’ll also take a look at some performance tests to see if Rust might be a viable alternative for Java applications using Apache Kafka®.
Announcing cfnts: Cloudflare's implementation of Network Time Security (NTS) in Rust by Watson Ladd and Pop Chunhapanya
Several months ago we announced that we were providing a new public time service. Part of what we were providing was the first major deployment of the new Network Time Security (NTS) protocol, with a newly written implementation of NTS in Rust. In the process, we received helpful advice from the NTP community, especially from the NTPSec and Chrony projects. We’ve also participated in several interoperability events. Now we are returning something to the community: Our implementation, cfnts, is now open source and we welcome your pull requests and issues.
Programming Servo: shipping message-ports(via a detour into Spectre) by Gregory Terzian
The thing about contributing to Servo is that you keep learning new things about the Web platform. Personally, I had never used messaging on the web when developing web applications, and I find it a fascinating idea.

Web-messaging enables developers to provide cross-site API’s without having to go through a server, all the while leveraging the client-side security model of the Web. And since it happens on the client, it could be more transparent to the end-user, and probably easier to block if necessary.

Implementing message-ports also raises interesting architectural questions. In an earlier Web(like, in 2017), an API like message-ports could have been implemented with some sort of cross-thread communication. In 2019 however, it’s going to have to go across process. Why? Something known as “Spectre”.
How to use gRPC with Rust Tonic and PostgreSQL database by Steadylearner
In this post, we will learn how to use Rust Tonic gRPC crate. We will learn how to implement CRUD with Postgresql database. The purpose of it is to help you to have the working Rust Tonic code and start your own porject immediately with it.
Battle of the Serverless — Part 2: AWS Lambda Cold Start Times by Mark Fowler
This experiment continues the work done in our pretend suite of microservices exposed via API Gateway to form an API with a code name of Slipspace in a mock company called STG. Slipspace drives are how the ships in the Halo universe travel so quickly to different sectors of the galaxy through something called Slipstream Space, so thought it was cool for a name requiring awesome warp API speeds.
SpO₂ the little dynamic monitoring tool by Clément Renault
At Meili, we needed a tool that allows us to monitor our pods, we already have vigil which health checks our front page and backend, but the number of these services is limited. We do not pop new front or backend servers dynamically (for now). When we create new search engines for the user we instanciate a kubernetes pod, we need to monitor the health of this service. Adding each of those URLs by hand in the vigil config file is not a solution.

So we decided that we needed a simple tool, a tool that can accept HTTP requests to register/unregister URLs to health check. We use the new async/await Rust syntax along with tide for the http server, no big deal here.
Creating Web App in Rust with Yew by Kris
I recently had to create a simple webapplication for a project i was working on. Luckily i was free to choose the technology for that task so i decided that it was great oportunity to try out how applicable is Rust for web development. There is already a bunch of mature web servers available such as Rocket or Actix. However as far as i can tell Yew is the only actual framework that allows you to create the frontend application.
Writing an HTTP server in Rust (Part I) by NullSense
So… You want to write an HTTP server. Well, you’re in luck, The Internet Engineering Task Force (IETF) is here to help us. Whenever they’re not fighting with fiber cables (at least that’s what I imagine they do), they are writing useful specifications for us! Well, first you prepare yourself a big pot of coffee. Once you’re appropriately caffeinated, you read the 57897 word RFC 2616 specification, written by none other, than the IETF. Exciting.
Tonic: gRPC has come to async/await! by Lucio Franco
I am pleased to finally announce a crate that I have been working very hard on for the past few months. tonic has finally hit the initial 0.1.0-alpha.1 release! Stable releases will follow in the coming months. Tonic is a gRPC-over-HTTP/2 implementation focused on high performance, interoperability, and flexibility. This library was created to have first class support of async/await and to act as a core building block for production systems written in Rust.
Building a front app with Rust (yes you can) and Yew by Terry Raimondo
JS/TS is killing me. Now that I use Rust everyday, I have to try Yew, a front framework for Rust to create WASM apps, I spotted it long time ago but it wasn’t mature enough for my use case… guess what — now is the time ! The project is still alive and well! Rust fullstack dev it is.
Osgood is a secure, fast, and simple platform for running JavaScript HTTP servers by Thomas Hunter II
Osgood is a secure, fast, and simple platform for running JavaScript HTTP servers. It is written using Rust and V8. Services written today share a common flaw: Being over-privileged. Osgood is an attempt to build a platform from the ground up, one which applies the Principle of Least Privilege at its very core. Osgood requires that policies be written ahead of time describing the I/O requirements of an application. If such an operation hasn't been whitelisted, it will fail. Developers familiar with JavaScript development in the web browser should feel right at home with the APIs provided in Osgood.
OAuth Requests, APIs, Diesel, and Sessions by Jeff Culverhouse
I start to get sessions working by POSTs OAuth requests to an API endpoint and create accounts using Diesel to talk to the database.
Curve Fitting in the Browser using Rust+wasm in Angular by Dominique Dresen
Playing around with Rust+WebAssembly and wrote a little crate to perform Levenberg-Marquardt fits. Brief comparison of SciPy & Rust fitting.

Wasmtime — a small and efficient runtime for WebAssembly & WASI by Wasmtime Developers
Wasmtime is a standalone wasm-only optimizing runtime for WebAssembly and WASI, using Cranelift. It runs WebAssembly code outside of the Web, and can be used both as a command-line utility or as a library embedded in a larger application.
Announcing the first Postgres extension to run WebAssembly by Ivan Enderlin
It is already possible to run WebAssembly inside C, C++, PHP, Python, Ruby, Go, C#, R. Now it is time to run WebAssembly inside Postgres.
Dreadbot: A Discord Bot for Magic The Gathering in Rust by Brian Carrigan
There is a wonderful Magic: The Gathering scene here in Durham, NC. Unfortunately, Magic often deserves the trope that it gets of being an expensive hobby. In order to enjoy the game on a budget, myself and a group of locals created a new format: Paper Dreadful. The format is simple: create a 60 card deck with a maximum of 4 of any card (other than basic lands) and the total cost must be $20 or less on that day. The same rule applies with the sideboard, except it must by $5 or less.

The problem here is that Magic cards change in price all the time. What happens if I build a deck and then a card skyrockets in price?
A Tiny, Static, Full-Text Search Engine using Rust and WebAssembly by Matthias Endler
I wrote a basic search module that you can add to your static website. It's very lightweight (around 50kB-100kB gzipped), should work with Hugo, Zola, and Jekyll. Only searching entire words is supported. Try the search box on the left side for a demo. The code is on Github.
Sample REST API in Rust and Go by Julio Merino
Over the summer, I prototyped a bunch of web apps whose ideas had been floating in my mind for a long time. I spent quite a bit of time learning about REST APIs and, as part of these exercises, implemented skeletons of REST servers in both Go and Rust. The app prototypes have gone nowhere but I thought of sharing the skeletons I built if only to serve as templates for myself in future work. Thus, in this post, I will cover these skeleton demos and I will compare them.
Picking Rust for web by Abe Winter
I’ve been staring at this energy efficiency across programming languages table for days. It can’t be right (why is typescript so much worse than javascript?) but a lot of it tracks with things I’ve observed from using these languages IRL. Also this web framework benchmarks project. Bottom line: I’m thinking about using rust as the backend for a small one-person web project. Here’s everything I said to myself while researching reasons not to.
Rustacean Terminal Chat App in Rust by Samba Diallo
Build a basic chat app with the Rust Programming Language.
How to use routers in Rust Frontend by Steadylearner
In the previous post How to use a modal in Rust, we learnt how to write a simple image modal with Rust frontend. We could find that we can build components visible only in specific conditions. In this post, we will learn how to use routers in Rust frontend with Yew. You will find that it is easy with an example.
Building with async/await in Rust by Ryan Ragona
As you might have heard, async/await is coming to Rust soon. This is a big deal. Rust has already has popular crates (tokio, actix) that provide asynchronous concurrency, but the async syntax coming to stable in 1.39 is much, much more approachable. My experience has been that you can produce and reason about application flow much more easily, which has made me significantly more productive when dealing with highly concurrent systems. To kick the tires of this new syntax I dug into the nightly branch, and built a high-performance TCP client called clobber. In this post I'll talk about why I think async/await in Rust is a big deal, and walk you some of the code in clobber.
Practical Networked Applications in Rust, Part 2: Networked Key-Value Store by Arve Knudsen
Welcome to the second installation in my series on taking the Practical Networked Applications in Rust course, kindly provided by the PingCAP company, where you develop a networked and multithreaded/asynchronous key-value store in the amazing Rust language. In the previous, and initial, post I implemented the course module of making the fundamental key-value store functionality, based around the Bitcask algorithm, which would only allow for local usage on your own computer. In the second module of my course work, I add networking functionality, dividing the application into a client/server architecture so that clients can connect to servers across the network.
Low-level TCP server in Rust with MIO by Sergey Melnychuk
It is time to get acquainted with Metal IO, low-level cross-platform abstraction over epoll/kqueue written in Rust. In this article I will show and explain how to write simple single-threaded asynchronous TCP server, then teach it to mock HTTP protocol, and then benchmark it with ab/wrk. The results are about to be impressive.
Practical Networked Applications in Rust, Part 1: Non-Networked Key-Value Store by Arve Knudsen
The PingCAP company, makers of the TiDB NewSQL database and the TiKV key-value store, have kindly made publicly available, as well as open-sourced, a set of training courses that they call the "PingCAP Talent Plan". These courses train programmers in writing distributed systems in the Go and Rust languages. They are originally intended by PingCAP to train students, new employees and new contributors to TiDB and TiKV and focus as such on subjects relevant to those projects, but are still appropriate to anyone with an interest in learning to make distributed systems in Go and/or Rust.
How to write Full Stack Rust code by Steadylearner
In the previous post How to modulize your Rust Frontend, we learnt how to use impl, functions and Yew components. They help you to find errors and organize your Rust frontend project. In this post, we will include server side code with ws-rs. It will help us to build complete Rust Full Stack chat app similar to what we made at How to start Rust Chat App.
How to modulize your Rust Frontend by Steadylearner
In the previous post How to use markdown with Rust Frontend, we learnt how to render markdown in Rust frontend and include CSS files from your previous frontend project. You can use a text, image, video, markdown or any HTML elements you want for your Rust frontend. In this post, we will learn how to modulize your Rust Yew frontend app. It will be easy after you learn how to use impl, function, and components for that.
Announcing Ballista - Distributed Compute with Rust, Apache Arrow, and Kubernetes by Andy Grove
After taking a break from working on Arrow and DataFusion for a couple of months to focus on some deliverables at work, I have now started a new PoC project to have a second attempt at building a distributed platform with Rust, and this time around I have the advantage of already having some foundational pieces in place, namely Arrow and DataFusion. I have also been gaining experience with Kubernetes recently and I could clearly see how this would simplify the creation of a distributed platform. The pieces really are starting to fall into place.

The new project is called Ballista and is a fast moving PoC taking a top down approach to building a distributed platform.
Gotham - From Start to Heroku by Daniel P. Clark
In this article, we’ll implement and deploy a Gotham full-stack web framework using the Tera template system, Webpack for a complete front-end asset management, a minimal VueJS and CoffeeScript web app and deploy to Heroku. Gotham is a Rust framework which is focused on safety, speed, concurrency and async everything. Webpack is a NodeJS website asset preprocessor and bundler which can let you use any of your favorite front end technologies. Combining these technologies allow for a small footprint on the server, which means saving money on infrastructure, very fast performance in page load for higher visitor retention and the full flexibility of client side code available to you for web design without limitations.
Rust as the new C. Part 1: building and combining native libs into C API by Victor Baybekov
In this blog series, I will experiment with Rust as a safer and simpler C/C++ replacement. The idea is to combine a couple of C dependencies in Rust, to do some work using the dependencies in Rust and to expose a final API from a Rust library via C ABI. Then I will consume the same exported Rust methods from a number of modern languages/platforms such as C#, Python, Java, Nodejs, R, Go and even back from C/C++.
Rust in one of the biggest music festival Atlas Weekend 2019 by /u/maxfrai
I'm happy to announce, that we've just finished one of the biggest European music festival Atlas Weekend which took place in Kyiv, Ukraine. As a year ago, backend for technical purposes of festival is written with Rust: Tickets exchange, entrance control, powerful user management with distributed configurable permissions, backstage pass, control of security workers, their work time, cars entrance, warehouse system for rfid bracelets with full history and control of each rfid. This year we registered more than 6000 workers, each of them has full info tied to bracelet: name, phone, photo, available permissions, time to access festival.

Writing a proxy in Rust and why it is the language of the future by Terry Raimondo
It’s been a year since I wrote a little proxy with Rust, it is one of my first projects with this language and I learned a lot writing it. To sum up a bit, the main goal of this proxy is to be really simple to use and easy to extend with middlewares. It targets HTTP APIs and can be used in front of a lot of services. This proxy has been used in multiple projects, with microservices architecture and so on…
Wasm By Example by Aaron Turner
A hands-on introduction into WebAssembly ( Wasm ). Containing simple examples and tutorials on how to implement concepts and various tasks using Wasm.
Implementing HTSP in Rust by Ruben De Smet
As with most hobby projects, my htsp-rs implementation became a side-side-side project, and it will probably stay that way. Another property of those hobby projects is that I now-and-then pick them up again, and htsp-rs has come to that point now. The reason for picking it up again is different from the reason of its existence though, and that’s a good thing: it means I have multiple reasons for the crate’s existence. Initially, I wanted it as a back-end for a livestreaming app on SailfishOS. Today, I want it as back-end for mpd’s TVHeadend support.
Auth Web Microservice with rust using Actix-Web 1.0 - Complete Tutorial by Harry Gill
We are going to create a web-server in rust that only deals with user registration and authentication. I will be explaining the steps in each file as we go. The complete project code is here repo. Please take all this with a pinch of salt as I’m a still a noob to rust 😉.
Asyncifying an Actix Web App and Upgrading it to 1.0 - zupzup by Mario Zupan
In a previous post, we created an Actix 0.7 Web App, which was not fully non-blocking. In this post, we'll become fully non-blocking and upgrade the app to Actix 1.0
Collaborative Editor in Rust by Caolan McMahon
I've been experimenting with techniques for collaborative editing in Rust recently and I'd like to share my first functional prototype with you. The demo uses Rust and WebAssembly, and I implemented it using a conflict-free replicated data type (CRDT) based on LOGOOT, which I modified to work with variable-sized strings rather than individual characters or lines.
Makepad, a live Rust authoring tool for 2D vector design, shaders and animation by makepad
The vision is to build a livecoding / design hybrid program, where procedural design and code are fused in one environment. If you have missed 'learnable programming' please check this out: http://worrydream.com/LearnableProgramming/ Makepad aims to fulfill (some) of these ideas using a completely from-scratch renderstack built on the GPU and Rust. It will be like an IDE meets a vector designtool, and had offspring. Direct manipulation of the vectors modifies the code, the code modifies the vectors.

However before we can make this awesome application, we need to build a UI stack. The aim of this toolkit is to be our stepping stone into building a livecoding IDE and designtools that don't suck or fall to pieces along the way.
Introducing Lightbeam: An Optimising Streaming WebAssembly Compiler by troubles.md

Actix - Actor System and Web Framework for Rust by Nikolay Kim
Actix web 1.0.0 is released - a small, pragmatic, and extremely fast web framework.
Gopher Server in Rust by Gokberk Yaltirakli
I find Gopher really cool. I think it’s a really nice way to organize information into trees and hierarchies, and as we all know programmers can’t resist trees. So recently I took an interest in Gopher and started writing my own server.

But recently it’s been gaining traction; so we should provide a decent landscape for new gophers, full of oxidised servers. Since I started using Gopher more often, it’s beneficial for me if there’s more content out there. So I’m writing this blog post to walk you through how to write your own server. We’ll be doing this in Rust.
Creating a Static HTTP Server with Rust – Part 2 by Levi Payne
In this series, we are creating a basic static HTTP 1.0 server with Rust. If you haven’t seen Part 1 yet, go do that first. At the end of Part 2, our server will do the following: Read and serve files from a predefined directory on the host server, Generate appropriate HTTP responses to incoming requests, Log information about the response to standard output.

Creating a Static HTTP Server with Rust - Part 1 by Levi Payne
In this series, we will create a basic static HTTP 1.0 server with Rust. At the end of Part 1 of this tutorial, our server will do the following: Listen for and handle TCP connections on a specific port, Accept HTTP 1.0 GET requests, Parse and validate requests for further use, Log incoming requests. We will avoid using libraries that make this trivial (i.e. the http crate) and focus on the fundamentals of how a server works.
Unit testing Rust using Chrome by Emil Sjölander
Stretch is a cross-platform Flexbox engine written in Rust. At Visly we are building a design tool for front-end engineers and we needed to ensure components looked the same across web, iOS, and Android without making use of WebViews. This meant replicating the web layout system on mobile.

In this post, I’ll cover the test setup we use in Stretch, how and why we need to generate unit dynamically. I’ll also cover an example of contributing another test to Stretch, and finally I’ll walk through how we also make use of this system for benchmarking.
Building Simple APIs with Hyper and Usher by Isaac Whitfield
When writing a web service, I often lean towards using tools that are as minimal as possible. One pretty obvious reason for this is the avoidance of dependencies you either don't want or don't need in your project. Whilst I'm not someone who goes out of their way to avoid dependencies, this is a pain point particularly in Rust because of the cost of building them repeatedly rather than shipping extra interpreted files around (especially if you use "pure" build environments).
WebAssembly -Part II.A | Wasm with Rust by Francisco Vilches
This article is more of a how-to on getting up and running with a production-grade web project which incorporates Rust (or any other language for that matter) and WebAssembly into your web pages.
Explained: Futures in Rust for Web Development by Bastian Gruber
If you are coming from NodeJS, Futures in Rust don't make much sense. In NodeJS, everything happens asynchronously. Therefore for you to be able to say "Hey, I really need to wait for the answer for this GET HTTP call", you are putting.then() on a Promise, so you can make sure you just execute the code inside the .then() when the HTTP call is finished.

In Rust, everything is blocking and synchronous by default, so you might ask yourself: "Why bothering with the complexity, that's exactly what I wanted in the first place!"
Rolling your own Router with Smithy v0.0.3 by Robert Balicki
Build a WebAssembly application with a hash router using Smithy.
Using Wasmer for Plugins Part 4 by Robert Masen
In the last three posts of this series we covered all of the things we would need to use Wasmer as the base for a plugin system. In part one we went over the basics of passing simple data in and out of a web assembly module, in part two we dug deeper into how you might do the same with more complicated data. In the last part we eased the experience of plugin developers by encapsulating all of our work into a library that exports a procedural macro. In this post we are going to explore what it would take to extend an existing plugin system to allow for wasm plugins.
Hawk: Image Recognition Application using Rust and AWS Services by muditchhabra6125
Rust is one of the newest kid on the block in the modern programming languages. We tried to take advantage of its great features by using it in an Image Recognition blueprint project.

Using Wasmer for Plugins Part 1 by Robert Masen
A few months ago, the Wasmer team announced a Web Assembly (aka wasm) interpreter that could be embedded into rust programs. This is particularly exciting for anyone looking to add plugins to their project and since Rust provides a way to directly compile programs to wasm, it seems like a perfect option. In this series of blog posts we are going to investigate what building a plugin system using wasmer and rust would take.

Introducing Smithy — WebAssembly framework for Rust by Robert Balicki
I’m extremely excited to announce the 0.0.2 release of Smithy, a web development framework for Rust! While it is a very pre-alpha version, it should be functional enough for others to start playing around with. Please, get your feet wet and provide feedback.
Announcing Lucet: Fastly’s native WebAssembly compiler and runtime by Pat Hickey
Today, we are thrilled to announce the open sourcing of Lucet, Fastly’s native WebAssembly compiler and runtime. WebAssembly is a technology created to enable web browsers to safely execute programs at near-native speeds. It has been shipping in the four major browsers since early 2017.
WASI example using Rust and Lucet by Herman J. Radtke III
Lucet is Fastly’s native WebAssembly compiler and runtime. Using the Lucet runtime and Rust’s wasm32-unknown-wasi target, we can create a WASM program that runs on the server.
Gloo Update: Onion Layers, Timers, and Events by Nick Fitzgerald
About two weeks ago, we kicked off our effort to collectively build Gloo, a modular toolkit for building fast and reliable Web apps and libraries with Rust and Wasm. We knew we wanted to explicitly cultivate the Rust and Wasm library ecosystem by spinning out reusable, standalone libraries: things that would help you out whether you were writing a green-field Web app in pure-Rust, building your own framework, or surgically inserting some Rust-generated Wasm into an existing JavaScript project. What was still fuzzy, and which we didn’t know yet, was how we were going design and expose these reusable bits.
Ocypod: Redis-backed job queue server with an easy to use HTTP interface by Dave Challis
Ocypod is a language-agnostic, Redis-backed job queue server with an easy to use HTTP interface. Its focus is on handling and monitoring long running jobs.
tarssh: An async Rust SSH tarpit by Thomas Hurst
tarssh is an SSH tarpit — a server that trickles an endlessly repeating introductory banner to clients for as long as it remains connected, in order to expend the resources of attackers. It's based on the same concept as Chris Wellons' Endlessh, a similar service written in C.
Seed: A frontend framework for Rust, via WebAssembly by David O'Connor
I'm distinguishing Seed through clear examples and documentation, and using wasm-bindgen/web-sys internally. I started this project after being unable to get existing frameworks working due to lack of documented examples, and inconsistency between documentation and published versions. My intent is for anyone who's proficient in a frontend framework to get a standalone app working in the browser within a few minutes, using just the quickstart guide.

Seed's different approach to view syntax also distinguishes it: rather than use an HTML-like markup similar to JSX, it uses Rust builtin types, thinly-wrapped by macros that allow flexible composition. This decision will not appeal to everyone, but I think it integrates more naturally with the language.
Resize images from S3 with AWS Lambda and Rust by Robert Beekman
Using Rust and AWS Lambda to thumbnail images, cheaply, relablity, and quickly.
Web Development with Rust: Deploy your first App by Bastian Gruber
If you learn something new, always have an updated version of your project in production. It keeps you motivated. We cover the most common options of how to do this in and with Rust.

WASP, a Lisp dialect for performant, concise Web Assembly modules by Noah
WASP is ‘a LISP programming language for extremely performant and concise web assembly modules.’ That means that you can use WASP to generate WASM modules.
Comparing C and Rust network protocol exercises - Ayende @ Rahien by Ayende Rahien
Almost by accident, it turned out that I implemented a pretty simple, but non trivial task in both C and Rust and blogged about them. Now that I’m done with both of them, I thought it would be interesting to talk about the differences in the experiences. The Rust version clocks at exactly 400 lines of code and uses 12 external crates. The C version has 911 lines of C code and another 140 lines in headers and depends on libuv and openssl.
Embedding WebAssembly in your Rust application by Brandon Fish and Lachlan Sneff
Wasmer is a WebAssembly runtime designed to run both standalone and embedded. The crate wasmer-runtime exposes an easy to use and safe api for compiling, creating imports, and calling WebAssembly from your own library. This tutorial goes over how to make a simple wasm application and run it using the wasmer-runtime!
Introducing swc (speedy web compiler) 1.0 by DongYoon Kang
swc(speedy web compiler) is a super-fast javascript to javascript compiler. It can transpile typescript / jsx / ecmascript 2019 to browser-compatible javascript. It's 16x - 20x faster than babel even on single-core synchronous benchmark. Note that actual performance gap is larger because swc works on worker thread while babel works on event loop thread.
Enjoy a slice of QUIC, and Rust! by Alessandro Ghedini
During last year’s Birthday Week we announced early support for QUIC, the next generation encrypted-by-default network transport protocol designed to secure and accelerate web traffic on the Internet.

We are not quite ready to make this feature available to every Cloudflare customer yet, but while you wait we thought you might enjoy a slice of quiche, our own open-source implementation of the QUIC protocol written in Rust.
Announcing OOProxy, a reverse OpenID and OAuth2 proxy by Tim Stokman
At HAL24K, we benefit a lot from open source software. That is why, to contribute back, we’ve started an internal program to open source some of the internal tools and libraries we’ve used to build our platform and machine learning solutions, starting with OOProxy. OOProxy is a reverse OpenID and OAuth2 proxy that we use to protect our HTTP-based machine learning APIs.
Replacing a hot path in your app's JavaScript with WebAssembly by Surma
In my previous articles I talked about how WebAssembly allows you to bring the library ecosystem of C/C++ to the web. One app that makes extensive use of C/C++ libraries is squoosh, our web app that allows you compress images with a variety of codecs that have been compiled from C++ to WebAssembly.

In my experience, most performance problems on the web are caused by forced layout and excessive paint but every now and then an app needs to do a computationally expensive task that takes a lot of time. WebAssembly can help here.
Why should you use Rust in WebAssembly? by Ryan Levick
WebAssembly (Wasm) is a technology that has the chance to reshape how we build apps for the browser. Not only will it allow us to build whole new classes of web applications, but it will also allow us to make existing apps written in JavaScript even more performant.

In this article about the state of the Rust and Wasm ecosystem, I'll try to explain why Rust is the language that can unlock the true potential of WebAssembly.
Exporting Serde types to TypeScript by Tim Ryan
I built my first web application with Rust and WebAssembly back in 2017. At the time, support for compiling Rust with the wasm32-unknown-unknown target had just landed, letting you run Rust code in the browser with few modifications. The downside was that loading and interacting with WebAssembly might require you to explicitly allocate and track memory. You might even need to manually decode UTF-8 strings in JavaScript:
WebGL + Rust: Basic Water Tutorial by Chinedu Francis Nwafili
In this tutorial we’ll discuss the ideas and concepts behind rendering water and then talk through some demo code.
Rust and WebAssembly in 2019 by Nick Fitzgerald
Compiling Rust to WebAssembly should be the best choice for fast, reliable code for the Web. Additionally, the same way that Rust integrates with C calling conventions and libraries on native targets, Rust should also integrate with JavaScript and HTML5 on the Web. These are the Rust and WebAssembly domain working group’s core values. In 2018, we made it possible to surgically replace performance-sensitive JavaScript with Rust-generated WebAssembly. I propose that we make larger-scale adoption of Rust and WebAssembly practical in 2019.
Async in Rust, circa 2018 by Aaron Turon
Rust 2018 has shipped, and we’re closing in on the end of the year. While we didn’t manage to ship async/await as part of the edition itself, the community has made quite a lot of progress toward that goal. This post summarizes the state of play, and announces the publication of several crates intended to facilitate use of async/await on the nightly ecosystem.

I am elated to announce that the next major release of Rocket is now available! Rocket 0.4 is a step forward in every direction: it is packed with features and improvements that increase developer productivity, improve application security and robustness, provide new opportunities for extensibility, and deliver a renewed degree of toolchain stability.
CFG Game: Put your CS skills to good use and craft burgers by Ricky Han
This past weekend I made a game for Ludum Dare 43. Tools used: Aseprite, quicksilver. Inspired by Zachtronics. It is written in Rust and compiled to WebAssembly.
Using Web Assembly in the Browser by Luke Jones
WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. This essentially means that is is fast, because the program is compiled to a much more compact format, making it faster to parse. Wasm can be written by hand if you're looking for a challenge, but is primarily meant to be written in another language, and then compiled to Wasm. You may know a little about Assembly language and how it works - here's a quick refresher in-case you're rusty.
Creating my first AWS Lambda using Rust by Konstantin
Taking advantage of AWS Lambda Runtime support for Rust
Dice.rs: Rust on Lambda by Kellen Frodelius-Fujimoto
Rust support on AWS Lambda was recently released, which seems like as good an opportunity as any to share some code and the solutions to challenges I encountered along the way ☺. I’ve decided to create a little diceware service, and the lambda-runtime crate provides a great API to make this a breeze.
Wherefore art thou Romio? by withoutboats
This blog post is about a project called Romio that I’ve been working on over the past two or three weeks. Romio is a port of a small part of the Tokio project to the newer futures APIs.

I started the project to get some experience porting code from the old futures API to the new API. However, we realized that this code could also be useful to other people who want to experiment with networking code using the new async/await syntax, so with the help of others we polished it up during the RustFest Rome “impl days” and now its being released for people to experiment with.
Safe Web Services with Actix and Sentry by Jan Michael Auer
Enjoy this quick introduction to creating a web server with Actix and monitoring it with Sentry.
Reflecting on Rust and WebAssembly in 2018 by Rust and WebAssembly
🎉 The 2018 edition of Rust has officially shipped, and the initial Rust and WebAssembly development story along with it! 🎉 To see how far we’ve come, let’s reflect on the Rust and WebAssembly story a year ago: rustc could emit WebAssembly binaries for you, but that was about it. As far as communication with JavaScript went, you had to work with raw wasm imports and exports yourself. That meant you could only pass 32- and 64-bit integers and floats back and forth. No Rust structs, JavaScript objects, strings, or slices could be passed back forth. And distributing your library’s .wasm so that other downstream projects could depend on it? Good luck.
Rust Web Survey Results 2018 by Bhargav Voleti
We recently sent out a survey regarding the state of the current Rust web ecosystem and we got over a 1000 responses! We really appreciate the feedback from the community. This will help us continue to improve upon the state of the Rust web ecosystem. Today, we would like to go over the responses and understand the results.
Rust Runtime for AWS Lambda by Stefano Buliani
AWS Lambda, which makes it easy for developers to run code for virtually any type of application or backend service with zero administration, has just announced the Runtime APIs. The Runtime APIs define an HTTP-based specification of the Lambda programming model which can be implemented in any programming language. To accompany the API launch, we have open sourced a runtime for the Rust language.
Tide’s evolving middleware approach by Aaron Turon
Since the last post on Tide, there have been a number of excellent contributions from a bunch of new contributors! In this post, I want to talk about the work that @tirr-c has done to substantially improve the middleware story.
Generic Methods in Rust: How Exonum Shifted from Iron to Actix-web by Exonum
In this article, we describe how we ported the Exonum framework to actix-web using generic programming.

Bringing Elm’s architecture to Rust and Webassembly by Sindre
I really like Elm. It is a delightful language with an amazing ecosystem. It has an interesting architecture called TEA, The Elm Architecture. Another language I like is Rust. On paper, Rust is completely different from Elm, but in using them both, I have seen some resemblance. Having used both Elm and Rust I had something I wanted to try. Would it be possible to create The Elm Architecture in Rust?
Serve archived static files over HTTP by Pascal Hertleif
Say you want to store a huge number of very small filesthat you will only access over HTTP.For example:You are using rustdoc to render the documentation of a library.Without much work you’ll end up with about 100k HTML filesthat are about 10kB each.As it turns out,this number of small files is very annoying for any kind of file system performance.Best case: making copies/backups is slow.Worst case: You’re using an anti virus software and it takes ages.
Middleware in Tide by Aaron Turon
After the positive response to the routing and extraction proposal in Tide, I’m pleased to say that an initial implementation is available on GitHub! As a testament to the strong foundation that Rust’s ecosystem provides, the basic framework implementation took only about 1,000 lines of code.
Serverless Rust by Doug Tangren
This is going to be the first post ( and hopefully not last ) in a series of posts about writing (and thinking about) serverless applications in Rust. Stay tuned…
Announcing Gotham 0.3 by @whitfin, @nyarly, @colinbankier
First of all, hello there! This is the first announcement after the call for maintainers back in summer, and includes the efforts of several new faces: @whitfin, @nyarly, @colinbankier. Together, as well as input from the original authors @bradleybeddoes and @smangelsdorf, we are the new maintainers of the Gotham project. Today we’re excited to announce the release of Gotham 0.3, which follows the evolution of the broader Rust ecosystem.
Auth Web Microservice with rust using Actix-Web - Part 2 by Harry Gill
Picking up from part one, we now have as server that takes an email address from a request and spits out a JSON response with an invitation object. In part one I said that we will send an email to the user, after some thought and feedback, we will be skipping this part now (look out for part 3). For now we will use the http response from the server to verify the email so to speak.
10x Your JavaScript With WASM And Rust by Claus
This is part four in a series of Rust on Azure Functions. The other parts are about performance comparisons (part 1 and part 2), and explaining the PMX algorithm (part 3). If you want to learn more about Genetic Algorithms be sure to read part 3 first).
Multithreading Rust and Wasm by Alex Crichton
When WebAssembly was first shipped it was an MVP which, while minimal, has spawned a huge number of exciting projects which work today across all major browsers. Rust has capitalized on the wasm MVP’s success as well with tools like wasm-bindgen and wasm-pack by making the MVP feel less minimal. WebAssembly is yet more ambitious, though! Since inception it’s always been intended to extend the WebAssembly specification with new features and functionality.
Auth Web Microservice with rust using Actix-Web by Harry Gill
We are going to create a web-server in rust that only deals with user registration and authentication. I will be explaining the steps in each file as we go. The complete project code is here repo. Please take all this with a pinch of salt as I’m a still a noob to Rust.
Serverless Rust with AWS Lambda and WebAssembly by Colin Eberhardt
In this post, I look at how WebAssembly can be used to create serverless functions and demonstrate an AWS Lambda function written entirely in Rust.
Routing and extraction in Tide: a first sketch by Aaron Turon
This post continues the series on Tide, sketching a possible design for routing and extraction that combines some of the best ideas from frameworks like Rocket, Actix, and Gotham.
Serverless Rust with Cloudflare Workers by Steven Pack
It's exciting times for Rust developers. Cloudflare's Serverless Platform, Cloudflare Workers, allows you to compile your code to WASM, upload to 150+ data centers and invoke those functions just as easily as if they were JavaScript functions. Today I'm going to convert my lipsum generator to use Rust and explore the developer experience (hint: it's already pretty nice).
Pi-hole: Announcing Our RESTful API by Pi-hole
The API is written in Rust, a language new to the Pi-hole project. Rust is a safe and fast language which matches well with our goals for the API. It is statically typed and prevents whole categories of errors while being productive and extendable.
Using WebAssembly to Accelerate Markdown Rendering by Chip Black and Jonathan Moore
Markdown rendering is very important to the performance of Semaphor - every message you send and read is a Markdown document - so we're always looking for ways to improve the performance of rendering Markdown. A couple months ago Jonathan Moore and I wondered how easy it would be to integrate WebAssembly into a React component, replacing the render() function, and we thought that moving Markdown parsing into Rust would be a great way to test this idea out.
WebAssembly and Dynamic Memory by Frank Rehberger
WebAssembly is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable target for compilation of high-level languages like C/C++/Rust, enabling deployment on the web for client and server applications.

These high-level languages like C/C++/Rust (+Javascript) deal with different allocations of memory, such as static memory, stack memory and dynamic memory.
Introducing Ruukh Framework by Sharad Chand
Rust has its goals set on to be a primary WASM language and it would be awesome to use it both in backend and frontend web. Ruukh is one of such efforts to realise that dream. Ruukh, a frontend web framework, is inspired by both VueJS and ReactJS.
Lessons learned on writing web applications completely in Rust by Sascha Grunert
This blog post is an update to the preceeding article “A web application completely written in Rust” and summarizes the projects’ progress over the last months.
Programming WebAssembly with Rust — The Book! by Kevin Hoffman
I am proud to announce that I’m working on a book for the Pragmatic Programmers. The title hasn’t been set in stone yet, but the book will be about programming WebAssembly with Rust.
Announcing the web-sys crate! by rustwasm
We are pleased to announce the first release of the web-sys crate! It provides raw bindings to all the Web’s APIs: everything from DOM manipulation to WebGL to Web Audio to timers to fetch and more!
eBPF, ingrained in Rust by Peter Parkanyi
Today we are releasing RedBPF and ingraind, our eBPF toolkit that integrates with StatsD and S3, to gather feedback, and see where others in the Rust community might take this framework. If you are looking to up your company’s monitoring game, gather more data about your Raspberry Pi cluster at home, or just have a strong academic interest in Rust and low-level bit shepherding, you might want to read on.
Tower Web 0.3 — async/await and template support by Carl Lerche
Today, Tower Web 0.3 has been released and it comes with two major new features: Experimental support for async/await. Support for using templates to render responses.
Smithy progress update: How I decreased WebAssembly bundle size by 90% by Robert Balicki
Smithy, a web development framework written in Rust that compiles to WebAssembly. In the mean time, there has been substantial progress, and Smithy is on the verge of being ready for alpha use! In this post, I want to describe the improvements that have been made, and what’s on the Smithy roadmap!
Announcing Linkerd 2.0: from service mesh to service sidecar by William Morgan
The 2.0 release of Linkerd brings two very significant changes. First, we’ve completely rewritten Linkerd to be orders of magnitude faster and smaller than Linkerd 1.x. Linkerd 2.0’s data plane is comprised of ultralight Rust proxies which consume around 10mb of RSS and have a p99 latency of <1ms. Linkerd’s minimalist control plane (written in Go) is similarly designed for speed and low resource footprint.
Rust and JavaScript Interop ↔️ by Ryan Levick
In recent projects of mine, I’ve been using WebAssembly quite a bit. WebAssembly (Wasm) is “a new binary instruction format for a stack based virtual machine” that lets you use languages besides JavaScript to run code on a web page - usually either for performance reasons or to run code you’d like to share across different platforms. In my opinion, the most promising of these languages, due to its lack of a need for a runtime and great tooling is Rust.
Rising Tide: building a modular web framework in the open by Aaron Turon
The Network Services Working Group aims to improve the story for web development this year in several respects: by bolstering foundations like async/await, by improving the ecosystem of web-related crates, and by pulling these pieces together into a framework and book called Tide. The name “Tide” refers to “a rising tide lifts all boats”; the intent is to improve sharing, compatibility, and improvements across all web development and frameworks in Rust.
Programming Servo: A generic “worker event-loop” by Gregory Terzian
Let’s take a look at how in Rust you can have an algorithm generic over T, where T is further bound by a trait, which itself is generic over one of several parameters.
Tower Web — Expanding the middleware stack by Carl Lerche
tower-web version 0.2.2 has been released. It comes with a number of new features, which I will talk about in this post. Primarily, the middleware story is starting to come together. I will be expanding some on how middleware fits into Tower and web in general.
Benchmarking a Rust web application by klausi
I set out out my goal 9 for Rustnish: Write benchmark code that compares runtime performance of Rustnish against Varnish. Use cargo bench to execute the benchmarks.

The basic idea of a performance test here is to send many HTTP requests to the web service (the reverse proxy in this case) and measure how fast the responses arrive back. Comparing the results from Rustnish and Varnish should give us an idea if our performance expectations are holding up.
Programming Servo: the makings of a task-queue by Gregory Terzian
In Servo, task-sources are implemented via a channel, whose sender is cloned for each specific task-source, and where tasks are messages sent on the channel and containing a closure representing the actual task.
From Rust to beyond: The ASM.js galaxy by Ivan Enderlin
The second galaxy that our Rust parser will explore is the ASM.js galaxy. This post will explain what ASM.js is, how to compile the parser into ASM.js, and how to use the ASM.js module with Javascript in a browser. The goal is to use ASM.js as a fallback to WebAssembly when it is not available. I highly recommend to read the previous episode about WebAssembly since they have a lot in common.
Oxidizing sourmash: WebAssembly by Luiz Irber
In "Oxidizing sourmash: Python and FFI" I described my road to learn Rust, but something that I omitted was that around the same time the WebAssembly support in Rust started to look better and better and was a huge influence in my decision to learn Rust. Reimplementing the sourmash C++ extension in Rust and use the same codebase in the browser sounded very attractive, and now that it was working I started looking into how to use the WebAssembly target in Rust.
From Rust to beyond: The WebAssembly galaxy by Ivan Enderlin
The first galaxy that our Rust parser will explore is the WebAssembly (WASM) galaxy. This post will explain what WebAssembly is, how to compile the parser into WebAssembly, and how to use the WebAssembly binary with Javascript in a browser and with NodeJS.
Programming Servo: Anatomy of a Fetch by Gregory Terzian
Today, let’s go through an entire fetch in Servo, starting with an example in JS.
Rust GraphQL webserver with Warp, Juniper and MongoDB by /dev/random
Rust's web frameworks ecosystem is in constant change, but recently a new framework called warp came out implementing a new, original way to solve the old problem of transforming a request into a response, and I wanted to give it a try.

And, as I use GraphQL massively at work, I also wanted to check how well Juniper implements it. To add some spice, I used MongoDB as a storage engine instead of the ubiquitous and well-supported SQL databases.

Tower Web 0.2 — Now 100% comment attribute free by Carl Lerche
The short version is, Tower Web 0.2 was just released and regular Rust attributes are now used instead of magic comments. The doc comment is replaced with #[get("/")]. This is thanks to Rust macro wizard David Tolnay. I also thought that it would be best to immediately push out 0.2 and then we can all pretend 0.1 didn’t happen.
Ray Tracing: WebAssembly vs JavaScript by Matt Harrison
For the past few months I've been toying about with WebAssembly. The examples I've built using WebAssembly were very simple and could easily have been written in JavaScript with perfectly adequate performance. This got me thinking it's about time I make something to really shows where WebAssembly shines. This led me down the path of thinking about very compute-demanding applications. An obvious example is 3d graphics rendering. Even a small scene like the ones I've been creating involve computing millions of vector dot product calculations per second. This kind of CPU-intensive application seemed right up the street of WebAssembly.
Syntax diagram generator by lukaslueg
This is a demonstration of a pure-rust library to generate syntax diagrams for macro_rules!().Diagrams are generated fully automatically from rust-source as Scalable Vector Graphics, using customizable CSS for layout.
Tower Web — A new web framework for Rust by Carl Lerche
I previously announced Tower and mentioned that a web framework was in the works. It took longer than I had hoped (as it sometimes does with software), but today, I am opening up Tower Web.

Tower Web is an asynchronous HTTP web framework that focuses on removing boilerplate. It is built on top of Tokio, Hyper, and of course Tower. It works today on stable Rust.
Introducing PrrrStack, Pt. 2 by Crash Springfield
In the first article of this series, we created a RestAPI for our application using Postgres, Rust, and Rocket. For the second half, we’ll be using React to create the front end.
warp by Sean McArthur
Over the past several months, I’ve been working a web framework in Rust. I wanted to make use of the new hyper 0.12 changes, so the framework is just as fast, is asynchronous, and benefits from all the improvements found powering Linkerd. More importantly, I wanted there to be a reason for making a new framework; it couldn’t just be yet another framework with the only difference being I’ve written it. Instead, the way this framework is used is quite different than many that exist. In doing so, it expresses a strong opinion, which might not match your previous experiences, but I believe it manages to do something really special.

I’m super excited to reveal warp, a joint project with @carllerche.
Is WebAssembly the return of Java Applets & Flash? by Steve Klabnik
For this post, I’m going to make three comparisons: to Flash, to Java Applets, and occasionally to PNaCL. Secondly, this post is going to focus on the web use-case for WebAssembly, even though the previous post was about non-web uses. We’ll make that comparison in the next post. Finally, this post is kind of like eating tapas, there’s a bunch of little sections.
A static web app in Rust by Benjamin Fry
A three day tour of Yew and WASM with Rust
Writing a front-end WebAssembly framework in Rust: lessons learned by Robert Balicki
Over the past few months, I’ve been writing Smithy, a very work-in-progress front-end WebAssembly framework written in Rust.

My goal for Smithy is to enable you to use idiomatic Rust to write front-end code. This has costs: for example worrying about lifetimes and using Rc> to share state. But this also has the potential to give you the safety guarantees that the Rust compiler provides when writing browser code!
How much of npm can you break? by Andrea Cognolato
The idea was simple, choose a package and recursively traverse npm to find all of the packages that depend upon it, after all the npm website offers a ‘Dependents’ tab on a package’s page. I had not anticipated the issues that made this an interesting technical problem.
Announcing the js-sys crate! by rustwasm
The js-sys crate contains raw #[wasm_bindgen] bindings to all the global APIs guaranteed to exist in every JavaScript environment by the ECMAScript standard. It does not contain bindings to any Web- or Node-specific APIs. With the js-sys crate, we can work with Objects, Arrays, Functions, Maps, Sets, etc… without writing the #[wasm_bindgen] imports by hand.
Rust + actix-web power Atlas Weekend music festival by /u/maxfrai
We've just finished music festival Atlas Weekend which took place in Kyiv, Ukraine. This year there were for about 450,000 visitors during 6 days. I'm glad to announce that Rust and actix-web are used as a backend for main technical purposes of festival.
The Return of: Can Rust speed up your Azure Functions? by Claus
A couple of weeks back I started using WASM on Azure’s FaaS (serverless/Functions as a Services) and unexpectedly the Rust version of my simple Monte Carlo estimation was considerably slower than its JavaScript counterpart. Clearly this needs more exploring! This time around the challenges will be harder and more practical. Let’s see how WASM and JavaScript perform.
actix – a basic TCP client by Tobias Bieniek
In our last post about actix we introduced you to the Rust programming language and the actix actor framework. This week we will build a basic TCP client with actix.
A web application completely in Rust by Sascha Grunert
My latest software architectural experiment is to write a complete real-world web application in Rust with as less as boilerplate as possible. Within this post I want to share my findings with you to answer the question on how much web Rust actually is.
Our Vision for wasm-bindgen by rustwasm
The last blog post laid out the Rust and WebAssembly domain working group’s overall vision for Rust and WebAssembly. In this blog post, we will dive into the details of wasm-bindgen, the future we envision for it, and how you can help us build that future.

Programming Servo: an HTTP cache by Gregory Terzian
In our previous post, we saw how combining channels with an event-loop could be a useful technique to ‘drive’ the concurrent logic of your system, and it was hinted at that shared mutable state might be more complicated. A good example of such ‘shared mutable state’ in Servo is the HTTP cache.
Rust with Rocket + Elm running on Heroku by Ethan Frei
I had this goal of making a web app that was very fast, stable and easy to deploy. This is what I was hoping to accomplish: strongly typed server-side and client-side languages (Rust & Elm respectively), push-button deployments to the cloud with free hosting initially, and sub-second response times for API calls and page loads. With this setup, I think I'm well on my way to accomplishing each of these.
Better HTTP Upgrades with hyper by Sean McArthur
Better HTTP Upgrades with hyper It’s been possible to handle HTTP Upgrades (like Websockets) in hyper if you made use of the low-level APIs in the server and client, but it wasn’t especially nice to...
Project Ice Puzzle by Matthew Michelotti
This game was coded in Rust and is playable in web browsers by means of WebAssembly, WebGL and Howler.js. The software I developed is partly open source in the form of Gate, which is the Rust library that powers this game and can power other similar games. Special thanks to the tools I used to create assets: Gimp, FL Studio and BFXR.
Our Vision for Rust and WebAssembly by rustwasm
Rust and WebAssembly can combine in many delightful ways. To consolidate our efforts and have the largest, most-positive impact we can, the Rust and WebAssembly domain working group is focusing on one vision:

Surgically inserting Rust compiled to WebAssembly should be the best choice for speeding up the most performance-sensitive JavaScript code paths. Do not throw away your existing code base, because Rust plays well with others. Regardless of whether you are a Rust or Web developer, your natural workflow shouldn’t change because Rust compiled to wasm integrates seamlessly into your preferred tools.

This blog post will expand on these aspirations and describe where we stand in relation to them right now. In a series of follow up posts, we will talk about the next steps for each major component of the Rust and WebAssembly ecosystem.
Streaming gRPC with Rust by Kevin Hoffman
Lately I’ve been working on a side project that involves aggregating the indexes of media libraries and allowing one library to “lend” a file to another. For example, I might use this system if I want my home tower to “lend” a file to my laptop before I get on a plane. I’ll be committing my work-in-progress on this project to github shortly (just want to get an MVP working first and do some refactoring), but I thought I would take a step back for a moment and share my thoughts on one aspect of this project: gRPC. In particular: gRPC streaming.
Writing a Web API Client in Rust (Part 3) by Owen Nelson
The 3rd of a multi-part series where we build a small REST client for the Marvel Comics Web API using Rust. This time we focus on how to use the hyper and futures crates to make HTTP requests to a Web API, then use serde to parse JSON data from the response.
Conspiracies, Dissemination, and REST APIs by Rob Rowe
Welcome to the third post in a series where I share my experience learning Rust. I’m building out a conspiracy theories API to help me get more familiar with Rust and have a little fun. Since I am new to Rust, I welcome all feedback, especially from developers who have been using Rust for quite some time. Leave a comment below or send your feedback via Twitter. Now it’s time to draw the blackout curtains, put on your foil-lined hat on and start serving up conspiracies from a REST API.
actix – an actor framework for the Rust programming language by Tobias Bieniek
The “actor model” is the main primitive that powers the Erlang programming language and its descendant, Elixir. It describes a programming model that simplifies the development of concurrent and multi-threaded applications or even applications that run distributed on multiple machines.

The complexity of actors is relatively low, and that is because the complexity is usually hidden in the actor frameworks that are used to run these types of primitives in the end. One example of such an actor framework is actix, which we will have a closer look at now.
Actix::From(Rocket) by noyez
I was inspired by Nick’s post to migrate my code from Rocket to Actix. I have also been nagged by recent struggles with the nightly compiler and its compatibility with all the other crates that I use and other the platforms that I use; my code runs on 32⁄64 bit arm and 32⁄64 bit x86. When I started using Rocket around a year ago, the nightly compiler was just as stable as the stable compiler, but things have changed as rust is a growing eco system.

For me, once the differences below were addressed, porting the code was relatively straightforward. The vast majority of my code remained the same.
Writing a Simple Github Webhook Responder With actix-web by Daniel Welch
Creating a simple web service for automating Travis builds across repositories using actix-web and Github webhooks.
hyper v0.12 by Sean McArthur
Today sees the release of hyper v0.12.0, a fast and correct HTTP library for the Rust language.

This release adds support for several new features, while taking the opportunity to fix some annoyances, and improve the extreme speeds!
HTTP Crate with URL Support & a Simple HTTP Client by Pyfisch
While the http crate generally has a great API I have been unsatisfied how it handles URLs. To create a HTTP request a full URL is needed with a scheme (http/https), authority (example.org) and a path (/search?q=rust) but http does enforce this and allows you to only state the path. This means both clients and servers are either unable to determine protocol and and authority information or have to do this manually.
Mix Rust Code (WebAssembly) with Vue Component by drsensor
In this tutorials, we will try mixing Rust code with Javascript by compiling Rust code as .wasm then use it in Vue Component.
Snowhash in Rust with WASM by Josh Leeb-du Toit
A little while ago I came across this Snowflake generator. It’s a project by Raph Levein that takes a hash string and uses it to procedurally generate a unique snowflake. He explains that the original motivation was as a cryptographically secure visual hash, so that people would reliably be able to tell by visual inspection whether two hashes were identical. I thought that was a pretty cool idea.
Wicked Fast Web Servers in Rust by Pete Mertz
I write code for the web every day, and as such, I naturally wanted to find a web server that I could write some beautiful code in Rust with. There are a few options out there, Actix, Rocket, but none of them are quite as simple and succinct as KoaJS for node. As such, I wanted to write something as simple as Koa and as performant as a Rust framework, and I did. With that, I give you Thruster, an elegant, performant, web server written in Rust.
Writing a Web API Client in Rust (Part 2) by Owen Nelson
The 2nd of a multi-part series where we build a small REST client for the Marvel Comics Web API using Rust. This time we focus on how to use the hyper and futures crates to make HTTP requests to a Web API, then use serde to parse JSON data from the response.
Migrating to Actix Web from Rocket for Stability by Nick Babcock
I previously wrote an article back in November 2017: Replacing Elasticsearch with Rust and SQLite. In it, I needed to create a few HTTP endpoints that ingested JSON, perform a database lookup, and return JSON. Very simple. No query / path parameters, authentication, authorization, H2, or TLS. I didn’t understand how stability was such an important feature. I was familiar with needing new versions of the nightly compiler to stay current with clippy and rustfmt, but it was a blindspot when it came to dependencies.
Creating a Rusty Rocket fuelled with Diesel by Dan Newton
Here I go with my first post that fully focuses on Rust. After spending a few months doing a bit here and there I decided to just dive right in as I was going through the Rust book at too slow a pace to keep myself interested. So, in this post I decided to write about setting up a simple REST API which is something that I have done in Java plenty of times but with Rust it is a different story.
A Small Rust API with Actix by Steve Zeidner
I had the need for a very small API for this website. So small, in fact, that only one endpoint was required. I've been doing a lot of development in Rust lately, so naturally Rust seemed like a good candidate to build this API in. I also wanted to try out a newer Rust web framework called Actix web. It claims to be a "small, pragmatic, and extremely fast rust web framework", which sounded perfect for what I needed.
Making microservices in Rust by Dylan Maccora
This is a small idea that I have been wanting to put together for quite some time now and finally have managed to get the time and most importantly experience in Rust to finally try something a little more than just small projects. One area that I think Rust is really making a decent headway in in the web domain, which I am assuming is likely due to its origin from Firefox. So I wanted to see if I could put together a really basic CRUD micro-service doing the ever so original TODO functionality.

Using LLVM from Rust, to generate WebAssembly by Jay Phelps
Hopefully this post helps jumpstart those who want to use LLVM from Rust. I also include how one could use this to generate WebAssembly, but the first part of this post is target platform agnostic.
How does dynamic dispatch work in WebAssembly? by Nick Fitzgerald
C, C++, and Rust all have some capability for dynamic dispatch: function pointers, virtual methods, and trait objects. On native targets like x86, all these forms compile down into a jump to a dynamic address. What do these forms compile down into when targeting WebAssembly?
Small WebAssembly Binaries with Rust + Emscripten by Alon Zakai
The Rust language is one of the earliest adopters of WebAssembly, and it has more than one way to compile to it:
Hello wasm-pack! by Ashley Williams
wasm-pack is a tool for assembling and packaging Rust crates that target WebAssembly. These packages can be published to the npm Registry and used alongside other packages. This means you can use them side-by-side with JS and other packages, and in many kind of applications, be it a Node.js server side app, a client-side application bundled by Webpack, or any other sort of application that uses npm dependencies. You can find wasm-pack on crates.io and GitHub.
How To Optimize JavaScript Code with Rust Part 1 by Raji Ayinla
In the first part of this Rust series, we’re going to walk through setting up Rust, writing Rust code, exporting the code, and using the code in our Node environment. By the end of this article, you’ll see how painless marrying Rust with JavaScript is.
Writing An NES Emulator with Rust and WebAssembly by bokuweb
I wrote the NES emulator with Rust and WebAssembly to learn Rust. It’s not perfect and have some audio bugs, but it’s good enough to play Super Mario bros.
JavaScript Interop with WebAssembly by Kevin Hoffman
In my last post I provided an introduction to WebAssembly — what is it, why do we care, and what does it look like? In this post, I’d like to explore a little bit of the inner workings of how we can communicate between Rust (wasm) and JavaScript. As I mentioned in the last post, WebAssembly is neither JavaScript nor some strongly-typed dialect. It is a standalone, compiled, portable binary. How you send data into and get data out of that binary involves some subtle nuances about how WebAssembly works.
The case for deadlines by Alkis Evlogimenos
Rust aims to be the foundation of fast and robust software. A thorn in that side is the choice of timeout-centric APIs for I/O and multithreading. I posit this was a bad choice and it needs to be remedied as soon as possible before more APIs proliferate this (possibly accidental) design decision.
Getting Yew to work with Rust on ‘Bash on Ubuntu on Windows’ by Raymond Siu
Yew is a new web framework written in Rust that takes concepts from React JS and Elm. It takes the two web libraries I love and combines them with the new language I love — Rust. I wrote this article because I haven’t found a lot of documentation online on how to get the Yew examples running, and I’m sure there will be people that will run into the same problems I did. I wrote this in hopes that it helps someone out there.

Welcome to this week in Rust and WebAssembly! by Sendil Kumar N
Hello and welcome to the first issue of This Week in Rust and WebAssembly! Rust is a systems language pursuing the trifecta: safety, concurrency, and speed. WebAssembly is designed as a portable target for compilation of high-level languages like C, C++, and Rust, enabling deployment on the web for client and server applications. This is a weekly summary of its progress and community.
Announcing Tower — A library for writing robust network services with Rust by Carl Lerche
Tower is a library for writing robust network services with Rust. It is being built in service of the Conduit proxy, which is using the Tokio ecosystem to build the world’s smallest, fastest, most secure network proxy. Tower will also provide a batteries included experience for implementing HTTP and gRPC services.
Using Rust Modules in JavaScript/Web Development (Part 3/ 3) [NodeJS] by Atul
Please read the Part 1 of the series here :
Making a 100% Statically-Linked, Single-File Web App with React and Rust by Anders Pitman
This tutorial will cover the basics of creating a minimal React app which can be deployed as a statically-linked Rust binary. What this accomplishes is having all of your code, including HTML, JavaScript, CSS, and Rust, packaged into a single file that will run on pretty much any 64-bit Linux system, regardless of the kernel version or installed libraries.
Using Rust Modules in JavaScript/Web Development (Part 2 / 3) [Webpack] by Atul
Part 1 of the post was primarily concerned with integrating rust modules with JavaScript with the help of wasm. But that involved a lot of manual procedures. Another more streamlined way is using webpack.
Improving GStreamer performance with tokio by Sebastian Dröge
For one of our customers at Centricular we were working on a quite interesting project. Their use-case was basically to receive an as-high-as-possible number of audio RTP streams over UDP, transcode them, and then send them out via UDP again. Due to how GStreamer usually works, they were running into some performance issues.

This blog post will describe the first set of improvements that were implemented for this use-case, together with a minimal benchmark and the results. My colleague Mathieu will follow up with one or two other blog posts with the other improvements and a more full-featured benchmark.

The short version is that CPU usage decreased by about 65-75%, i.e. allowing 3-4x more streams with the same CPU usage. Also parallelization works better and usage of different CPU cores is more controllable, allowing for better scalability. And a fixed, but configurable number of threads is used, which is independent of the number of streams.
HTTP upgrades with hyper by Sean McArthur
The newest release of hyper includes some lower-level connection APIs for both the server and client. Notably, this allows using hyper send and receive HTTP upgrade requests. The most popular of these is Websockets.
Using Rust Modules in JavaScript/Web Development (Part 1 / 3) [Plain JS] by Atul
One of the promising reasons I started learning rust is that it can be used to build modules for web using web-assembly. This blog post will cover how you can build a rust module and use it as regular package in the JavaScript environment. Remember rust is not meant to replace JS. I see it as complementary add-on to the places where JS is comparatively slower (heavy computations).
JavaScript to Rust and Back Again: A wasm-bindgen Tale by Alex Crichton
Recently we’ve seen how WebAssembly is incredibly fast to compile, speeding up JS libraries, and generating even smaller binaries. We’ve even got a high-level plan for better interoperability between the Rust and JavaScript communities, as well as other web programming languages. As alluded to in that previous post, I’d like to dive into more detail about a specific component, wasm-bindgen.
Removing Connection State In mob by Herman J. Radtke III
I started writing mob, an multi-echo server using mio, in 2015. I coded mob into a mostly working state and then left it mostly alone, only updating it to work with the latest stable mio. Recently, I started looking at the code again and had the urge to improve it. In a previous post, I talked about managing the state of connections in mob. In this post, I will walk through what I did to remove the need to track connection state. I wanted to remove the state because the implementation required an O(n) operation every tick of the mio event loop. It also added a fair amount of complexity to the code.
Rust + Node.js are awesome! by Benjamín Calderón
Blazing fast, low requirements, computationally intensive operations on Node.js using Rust
Touring a Fast, Safe, and Complete(ish) Web Service in Rust by Brandur Leach
For years now, I’ve been having a crisis of faith in interpreted languages. They’re fast and fun to work in at small scale, but when you have a project that gets big, their attractive veneer quickly washes away. A big Ruby or JavaScript (just to name a few) program in production is a never ending game of whack-a-mock – you fix one problem only to find a new one somewhere else. No matter how many tests you write, or how well-disciplined your team, any new development is sure to introduce a stream of bugs that will need to be shored up over the course of months or years.

Central to the problem are the edges. People will reliably do a good job of building and testing the happy paths, but as humans we’re terrible at considering the edge conditions, and it’s those edges and corners that cause trouble over the years that a program is in service.
Building a Restful CRUD API with Rust by Sean Wragg
Since my initial Node/Rust REST comparison, I’ve wanted to follow up with a comprehensive guide for getting simple CRUD operations up and running in Rust.

Building a DNS server in Rust by Emil Hernvall
With the combined goal of gaining a deep understanding of DNS, of doing something interesting with Rust, and of scratching some of my own itches, I originally set out to implement my own DNS server. This document is not a truthful chronicle of that journey, but rather an idealized version of it, without all the detours I ended up taking. We'll gradually implement a full DNS server, starting from first principles.
Parc3l: Combining Three.js, Rust, and WebAssembly! by Andres Cuervo
WebAssembly has been interesting me lately, specifically the prospect of doing arithmetically-intensive operations with it, not unlike the fantastic physics engine Emscripten port Ammo.js. Compiling something like that is out of the scope of this little post (but should be getting easier!), and I’ve left some links at the bottom so you can clear more about WebAssembly if you’re interested.
Making WebAssembly better for Rust & for all languages by Lin Clark
To be a useful as a web language, Rust needs to work well with the JavaScript ecosystem. We have some work to do to get there, and fortunately that work ...
Crashing a Rust Hyper server with a Denial of Service attack by Klaus Purer
I’m writing a reverse proxy in Rust using Hyper and I want to measure performance a bit to know if I’m doing something terribly wrong. By doing that I discovered a Denial of Service vulnerability in Hyper when IO errors are not properly handled. Note that a workaround has been released in the meantime in Hyper 0.11.20, more background info can be found in this Hyper issue.
Writing a Simple IPFS Crawler by Gökberk Yaltıraklı
IPFS is a peer-to-peer protocol that allows you to access and publish content in a decentralized fashion. It uses hashes to refer to files. Short of someone posting hashes on a website, discoverability of content is pretty low. In this article, we’re going to write a very simple crawler for IPFS.
It’s challenging to have a traditional search engine in IPFS because content rarely links to each other. But there is another way than just blindly following links like a traditional crawler.
Writing servers with Tokio by Félix Saparelli
I’ve been writing a small toy project with Tokio in my spare time’s spare time. I’ll write more about it at a later date. What I’ve found writing it, though, is that there is a specific pattern to writing servers, both UDP and TCP (and presumably others) in Tokio, and it’s not super obvious at first glance. So here it is.
Writing a Microservice in Rust by Peter Goldsborough
Let me begin this article on Writing a Microservice in Rust by talking about C++. I’ve been a reasonably active member of the C++ community for quite a while now, attending and contributing talks to conferences, following the development and evangelism of the language’s more modern features and of course writing lots of it. C++ is a language that gives its users very fine-grained control over all aspects of the program they are writing, at the cost of a steep learning curve and a large body of knowledge required to write effective C++. However, C++ is also a very old language, conceived by Bjarne Stroustrup in 1985, and thus caries a lot of technical debt even into modern standards.
Speed Without Wizardry by Nick Fitzgerald
Vyacheslav Egorov, who goes by mraleph on the Web, wrote a response to my article “Oxidizing Source Maps with Rust and WebAssembly” titled “Maybe you don’t need Rust and WASM to speed up your JS”.

The “Oxidizing” article recounts my experience integrating Rust (compiled to WebAssembly) into the source-map JavaScript library. Although the JavaScript implementation was originally authored in idiomatic JavaScript style, as we profiled and implemented speed improvements, the code became hard to read and maintain. With Rust and its zero-cost abstractions, we found that there was no trade-off between performance and clean code.
Recently, for a Rusty Web by Sean McArthur
It’s been a few months since I shifted my focus full time to Rust, and in that time, we’ve gotten a lot of work done! I wanted to update you here what all that is, since it’s spread around on multiple repositories.
Porting Rust to WebAssembly by John-John Tedro
I recently spent some effort trying to make reproto run in a browser. Here I want to outline the problems I encountered and how I worked around them. I will also provide a number of suggestions for how things might be improved for future porters.
Fanta: An opinionated framework for web development in rust by Peter Mertz

Gameland intro, reimplemented in Rust for WebAssembly by Per Lundberg
My nice brother Johannes Ridderstedt sent me some old files a few weeks ago (in late 2017), stuff that he had preserved from an age-old computer of ours. One of these was the file named gameland.zip (not published yet, but I might put it up here some day.) I managed to get this running, and liked what I saw (you'll find the YouTube link to it further down on this page.) Around this time I was reading a bit about WebAssembly which I think will redefine and help reshape the web as we see it today. I was also looking at the Hello, Rust web page, and the "FizzleFade effect using a Feistel network" page in particular.
Event Sourcing with Aggregates in Rust by Kevin Hoffman
