  • swc

    Rust-based platform for the Web

    Project mention: Docusaurus 2.0 – Meta's static site generator to build documentation sites | | 2022-08-01

    IMHO Rust is useful for its speed. Many frontend tools use Rust today (like swc, napi-rs...).

    We are willing to include Rust in Docusaurus in the future (alongside Node.js), as it can help to build the static doc site faster. BTW our docusaurus prod site ( is built using swc already (

    Now using a 100% Rust tool to build a doc site would be great too, but at the end of the day if you want a great experience you'll also need some JS and not just plain static HTML files. And Rust devs are more likely less "frontend-y" (I've been a backend Scala dev 10 years ago, I know how good looking UIs are produced by backend devs ^^). So I guess a combination of Node.js + Rust is great, and the frontend community that care about UI/UX is more likely to contribute to the JS side to polish things.

    Status, process, and documents for ECMA-262

    Project mention: Show HN: We are trying to (finally) get tail-calls into the WebAssembly standard | | 2022-07-12

    4. Proposed something else [ ]

    While apple is against Syntactic tail calls, they’re mainly just opposed to versions of it that would remove/unrequire the tail-call optimisation they already do:

    For the version of it that is backwards compatible, they wouldn’t need to do anything other than recognise it as valid syntax. Their main concern is that it "could add confusion with very little benefit."

  • eslint-plugin-react

    React-specific linting rules for ESLint

    Project mention: Same file components vs functions that return JSX | | 2022-07-25

    Prevent creating unstable components inside components (react/no-unstable-nested-components)

  • esprima

    ECMAScript parsing infrastructure for multipurpose analysis

    Project mention: Algorithm to simplify a 100-variable Boolean expression? | | 2022-06-04

    I used ESPrima, but any parser would do in this case. I then wrote a simple function to extract all "atomic" non-boolean expressions from it.

  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

  • boa

    Boa is an embeddable and experimental Javascript engine written in Rust. Currently, it has support for some of the language.

  • escodegen

    ECMAScript code generator

    Project mention: How to make your own programming language in JavaScript | | 2022-05-07

    What's cool about Esprima syntax is that there are tools that generate code based on their AST. An example is escodegen which takes Esprima AST as input and outputs JavaScript code. You can think that you can use just strings to generate code, but this solution will not scale. In this tutorial, I show only a single if statement but you will run into a lot of problems if you will have more complex code.

  • eslint-config-standard

    ESLint Config for JavaScript Standard Style

    Project mention: [AskJS] favorite JavaScript library | | 2022-05-28

    Hmm right, haven't found too many controversial things in, besides no-semi fixed by semi-standard and comma-dangle "never" (sucks for git history, they should allow it for multiline cases

  • neo

    The application worker driven frontend framework (by neomjs)

  • eslint-plugin-node

    Additional ESLint's rules for Node.js

    Project mention: 14 Linting Rules To Help You Write Asynchronous Code in JavaScript | | 2022-03-25

    The following rules are additional ESLint rules for Node.js provided by the eslint-plugin-node plugin. To use them, you need to install and add the plugin to the plugins array in your .eslintrc configuration file.

  • estraverse

    ECMAScript JS AST traversal functions

  • binjs-ref

    Reference implementation for the JavaScript Binary AST format

    Project mention: Python is in the browser. No idea if this will lead to chaos or harmony... | | 2022-05-01

    There was a proposal a little while back for BinAST which gets you some of the same benefits as bytecode, but not all... mainly just reducing the parse time and maybe even allowing more pipelined evaluation. See

  • jk

    Configuration as Code with ECMAScript

    Project mention: The Curse of NixOS | | 2022-01-24

    People have tried:

    But yeah I agree. The thing is, if all you need is robust determinism why do you need a full functional language with currying and other complex concepts?

    Google had the same problem for Bazel, and their solution (Starlark) is way easier to understand.

  • snuggsi

  • JavaScriptEngineSwitcher

    JavaScript Engine Switcher determines unified interface for access to the basic features of popular JavaScript engines (ChakraCore, Jering.Javascript.NodeJS, Jint, Jurassic, MSIE JavaScript Engine for .NET, NiL.JS, Microsoft ClearScript.V8 and VroomJs). This library allows you to quickly and easily switch to using of another JavaScript engine.

  • awesome-standard

    Documenting the explosion of packages in the standard ecosystem!

  • js-tokens

    Tiny JavaScript tokenizer.

    Project mention: Edit code from browser | | 2022-07-05

    Filtering out components from other code may be tricky. Even if you assume any file ending in .jsx or .tsx is a component it's still possible for those files to export other functions or multiple components. So you have to figure out which exported function is the component. Maybe assume any function starting with a capital letter (e.g. "Component") is a component. You may want to investigate Javascript tokenizers like js-tokens, which will make it easier for you to examine the code inside of each file. But a few regular expressions would work as well.

  • kataw

    An 100% spec compliant ES2022 JavaScript toolchain

    Project mention: We've been lied to: JavaScript is very fast | | 2021-10-12

    It then builds on the assumption that all of Javascript performance scales linearly based on the results of that fishy benchmark. Never mind that in C you can stack allocate, or use arena allocators, or use a million of other tricks, where in JS, once you write {}, you got a heap allocation that you don't have any control over (and if you think this doesn't matter, this is one of the reasons why esbuild is so much faster than babel, or heck even kataw, the fastest JS parsing toolkit I'm aware of).
