Is it as fast as people are saying? How stable is it? Is it really better than Node? And can I use it with continuous integration? What is Bun? Bun is the newest addition to the JavaScript family. It has been making waves that rival those made by Deno when it came out in 2018. Bun sits in the space between Node and Deno. Bun, like Deno, supports TypeScript out of the box and offers developer-frien
January 14, 2022 HEY is running its JavaScript off import maps The advent of import maps, and the bundler-less JavaScript reality it introduced, was undoubtedly my favorite advancement in web tech for 2021. Between Guy Bedford's excellent shim and native support in Chrome 89, we've finally been granted an escape from a decade's worth of frustrating complexity with excess tooling. Usually progress
EngInfraAce, CodeMirror, and Monaco: A Comparison of the Code Editors You Use in the Browser I’ve been working on Replit for roughly six years now, and as the team has grown, I’ve focused on the IDE (what we call the workspace) portion of the product. Naturally, I was increasingly preoccupied with the code editor. While we’ve considered creating a code editor that meets our needs, the complexity i
I'm very excited to announce @parcel/css, a new CSS parser, compiler, and minifier written in Rust! Check it out on GitHub, or try a live demo right in your browser. Parcel CSS has significantly better performance than existing tools, while also improving minification quality. In addition to minification, Parcel CSS handles compiling CSS modules, tree shaking, automatically adding and removing ven

Lume is the Galician word for fire but also a (yet another) static site generator for Deno. It’s inspired by other general-purpose static site generators, such as Jekyll and Eleventy, but it’s faster, simpler and easier to use and configure, besides being super flexible. Supports multiple file formats, like Markdown, YAML, JavaScript, TypeScript, JSX and Nunjucks, and it’s easy to extend. You can
Rust is a fast, reliable, and memory-efficient programming language. It's been voted the most loved programming language six years in a row (survey). Created by Mozilla, it's now used at Facebook, Apple, Amazon, Microsoft, and Google for systems infrastructure, encryption, virtualization, and more low-level programming. Why is Rust now being used to replace parts of the JavaScript web ecosystem li

You can now write Cloudflare Workers in 100% Rust, no JavaScript required. Try it out: https://github.com/cloudflare/workers-rs Cloudflare Workers has long supported the building blocks to run many languages using WebAssembly. However, there has always been a challenging “trampoline” step required to allow languages like Rust to talk to JavaScript APIs such as fetch(). In addition to the sizable
In our team at Rakuten, we have been using Elm1 in production for almost two years now. This post is about our story, the lessons we learned, and our likes and dislikes. This post is quite long so if you prefer to see an overview, feel free to jump to the index. Everything started in the Berlin branch of Rakuten during the summer of 2017. We were maintaining a medium-size single-page application w
August 12, 2021 Modern web apps without JavaScript bundling or transpiling I didn't much care for vanilla JavaScript prior to ES6. Through all of the 2000s, I chased different approaches to avoid writing too much of it. First there was RJS (Ruby-to-JavaScript). Then there was CoffeeScript. Both transpiling approaches that turned more enjoyable-to-write source code into the kind of JavaScript that
This article is aimed at beginners who've never had the chance to see 'why React'. It takes a very contrived example to make a point about how React's declarative state model could help keep state sanity when code scales. If you're an experienced developer these series of posts by Steven might give deep insights about why declarative abstractions scale in a way you might not have thought before. T
Sorting colors in JavaScriptJune 22, 2021How to sort colors in JavaScript? Let me tell you a story first. In the project I'm working on right now we used to have 134 colors in use! WTF?! you say. Once I discovered that I thought I'm going to show that to my colleagues, and we will address the problem. Unfortunately, I'm a very visual person (so to say) and I couldn't stand the very random order of

JavaScript in the browser runs many times faster than it did two decades ago. And that happened because the browser vendors spent that time working on intensive performance optimizations. Today, we’re starting work on optimizing JavaScript performance for entirely different environments, where different rules apply. And this is possible because of WebAssembly. We should be clear here—if you’re run
Q-Successは2021年5月4日（米国時間）、Webサーバ技術の使用サイト数に基づく市場シェア調査結果を発表した。「Nginx」と「Apache」がともに33.8％を占め、わずかな差でNginxが首位、Apacheが2位となった。 2009年にWeb技術調査サービス「W3Techs - World Wide Web Technology Surveys」が開始されて以来、NginxがApacheを抜いて首位となったのは、今回が初めてだ。 2009年のシェアはNginxが3.7％、Apacheが73％超、Microsoftの「インターネットインフォメーションサービス（IIS）」が20％程度だった。Apacheのシェアは、1年前はNginxを6.6ポイント上回っていたものの、一貫して低下傾向が続いている。 調査対象のWebサーバ技術の数は現在、98に達しており、2021年5月4日付の市場
