Why use Vite when Bun is also a bundler? - Vite vs. Bun

1. vite

   1 876 70,040 9.9 TypeScript

   Next generation frontend tooling. It's fast!

   

   Vite is a fast local development server, which uses a bundler to create the bundle of JS that the client receives. It currently uses two bundlers, actually.

3. zig

   2 855 36,516 10.0 Zig

   General-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

   

   Bun is not just a Node replacement, but a Zig port of esbuild (initially the same fast algorithm), so includes it's own (currently limited) bundler:

4. bun

   3 349 75,376 10.0 Zig

   Incredibly fast JavaScript runtime, bundler, test runner, and package manager – all in one

   

   Vite has Hot Module Reloading (HMR), which is important for fast local development. Bun's HMR currently has at least one open issue.

5. esbuild

   4 347 38,446 9.0 Go

   An extremely fast bundler for the web

   

   For production, Vite can use another bundler, esbuild, to speed up transpilation and minification, while it in production also uses the bundler Rollup to create the client side JS bundle, due to Rollup's flexible API. Even though Vite uses ESM in development environment, for speed. In the future Vite may use esbuild entirely for bundling instead of Rollup, due to the speed it would gain.
