Show HN: TypeScript for the Browser
does esm.sh/tsx send source to their servers? I was under the impression it uses a rust-based wasm compiler in the browser locally https://swc.rs/#features

What Rust projects are you most excited about?
I'm most excited about SWC, the TypeScript and JavaScript compiler written in Rust.

Rust Dependencies Scare Me
I once wanted to contribute to the popular swc project (https://github.com/swc-project/swc). I cloned the repo, ran build, and a whooping 20GB was gone from my disk. The parser itself (https://github.com/swc-project/swc/blob/main/crates/swc_ecma...) has over a dozen dependencies, including serde.
Meanwhile, the heaviest JavaScript parser implemented in JavaScript is more lightweight.
I decided that I should leave this project alone and spend my time elsewhere.

A 10x Faster TypeScript

Matanuska ADR 017 - Vitest, Vite, Grabthar, Oh My!
But I also had my Vitest build configured to use SWC, the compiler backend I had configured for Vitest, and it had issues of its own. SWC is cool. It's a TypeScript compiler written in Rust that is extremely fast, and - unlike tsc - it mostly handles rewriting import paths just fine. However, I did find that it rewrites index.mjs imports into directory imports.

Fresh Start: Unlocking New Beginnings with GitHub Copilot
# React + Vite This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules. Currently, two official plugins are available: - [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react/README.md) uses [Babel](https://babeljs.io/) for Fast Refresh - [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh # Fresh-Starts

TypeScript 7: 10x Speedup and the Go Language 🚨
First of all, the original TypeScript compiler under the hood is moving in the new version 7 from JavaScript to Go. That is, there will be conditionally TypeScript 6 (JS) and TypeScript 7 (Go). This was done mainly because of the scaling problem when used in very large projects, but also, of course, because of the speed.

Why Go?
Since you wrote this it looks like [Anders replied](https://github.com/microsoft/typescript-go/discussions/411#d...) to one of the threads.
I have to agree with the sentiment that is a success story that the team is allowed to use the best tool for the job, even if it suffers from "not built here".
This is really healthy and encouraging to see in these large OSS corporate-sponsored projects, so kudos to you and the team for making the pragmatic choice.

What are some alternatives?
When comparing swc and typescript-go you can also consider the following projects:
esbuild - An extremely fast bundler for the web
Godot - Godot Engine – Multi-platform 2D and 3D game engine
vite - Next generation frontend tooling. It's fast!
porffor - An ahead-of-time JavaScript compiler
ts-loader - TypeScript loader for webpack
