  • Why Is Esbuild Fast?
    news.ycombinator.com | 2021-02-16
    Hey, I was trying to do this same thing for a TypeScript project I was bootstrapping. Digging around the issue tracker, I recall the maintainer stating that this is currently not in the scope of esbuild, and that swc[0] might be better suited for this.

    Personally, I wrote a crude JS script using the esbuild transform API + node-watch to compile .ts files and copy files/folders during development. This is all very recent, so I can't ensure that it's bulletproof quite yet.

    swc (https://github.com/swc-project/swc) is a rust equivalent to babel and has a bundler under development. Not sure how far along it is.

    That would be an interesting comparison of performance and features.

    swc is more ambitious, it wants to re-implement all of tsc type checking, not only transpiling: https://github.com/swc-project/swc/issues/571
    news.ycombinator.com | 2021-02-16
    Yup, impressive.

    SWC, another competitor project written in rust is also handled exclusively by a single person. Half a million lines of code and they have even built a type checker which is not open source.

    It appears like SWC will get a port of terser soonish:


  • JS minification benchmarks: babel-minify, esbuild, terser, uglify-js
    Check out esbuild and SWC.
  • Browser live reload template?
    Agreed that it used to be a headache but it's become much easier in the past few years. Babel, or swc (a babel alternative built in Rust that's crazy fast) now support typescript out of the box and both have loaders available.

    I've never used it, but [1] claims to be a much faster js/typescript compiler than some of its competitors and written in Rust.

    About performance, I tested in swc long time ago, in swc scenario napi-rs is 2x faster than neon's legacy backend: https://github.com/swc-project/swc/issues/852. Compare with the neon's napi backend, the performance won't be very different. But the napi backend of neon is incomplete.
