  • Announcing Parcel CSS: A new CSS parser, compiler, and minifier written in Rust!
    8 projects | /r/rust | 12 Jan 2022
    I love seeing more and more of the frontend tooling space migrating to Rust. Next.js recently moved their TypeScript compiler to swc , which Parcel is also using. Parcel also has a source maps library written in Rust. The Rome Toolchain is being rewritten in Rust. And I strongly suspect there are at least a couple other large scale Rust-for-the-frontend projects being built at FAANG-scale companies :)

    First, we switched the default compiler for new projects from Babel to SWC (Speedy Web Compiler). SWC is dramatically faster than Babel and requires zero configuration. We’ll continue to support Babel in any project currently using it.

    As the reference explains “**SWC** (Speedy Web Compiler) is an extensible Rust-based platform that can be used for both compilation and bundling. Using SWC with Nest CLI is a great and simple way to significantly speed up your development process.”
  • Ruby Outperforms C: Breaking the Catch-22
    4 projects | news.ycombinator.com | 9 Sep 2023
    This is specifically about breaking the myth that performing expensive self-contained operations (e.g, parsing GraphQL) in a native extension (C, Rust, etc.) is always faster than the interpreted language.

    The JS ecosystem has the same problem, people think rewriting everything in Rust will be a magic fix. In practice, there's always the problem highlighted in the post (transitioning is expensive, causes optimization bailouts), as well as the cost of actually getting the results back into Node-land. This is why SWC abandoned the JS API for writing plugins - constantly bouncing back and forth while traversing AST nodes was even slower than Babel (e.g https://github.com/swc-project/swc/issues/1392#issuecomment-...)

  • Show HN: Ezno, a TypeScript checker written in Rust, is now open source
    4 projects | news.ycombinator.com | 7 Jun 2023
    Very cool! I'm curious, is this intended for dev tooling?

    For example, I could see this (or something similar) being useful as the engine for a typescript language server that would be faster than the standard one

    But if it's not aimed at 1:1 with tsc, would it be intended more for something like swc[1]?

    Or what would you expect people to use this for, besides just being a cool project to learn from?

    This is... good news, but I still cannot fathom using the default Typescript compiler for regular development. Seriously, leave the type-checking to your IDE and CICD chain, and switch to using tsx (https://www.npmjs.com/package/tsx) or swc (https://swc.rs/) and you will _immediately_ notice the difference in speed and productivity.
