It is part of the TypeScript Academy learning path, one of 3 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Intro
Goal: Explore popular bundlers—Vite, esbuild, SWC, and Rollup. Each offers unique speed and flexibility.
Vite
Vite: Instant dev server using ESM, fast HMR, production builds powered by Rollup.
// package.json
{
"scripts": {
"dev": "vite",
"build": "vite build"
}
}esbuild
esbuild: Extremely fast bundler in Go. Great for prototyping and JS/TS projects.
// Command
npx esbuild src/index.ts --bundle --outfile=out.jsSWC
SWC: Rust-based compiler for TS/JS. Often used in Next.js for speed.
// swc config (.swcrc)
{
"jsc": {
"parser": { "syntax": "typescript" },
"target": "es2020"
}
}Rollup
Rollup: Flexible bundler, strong tree-shaking. Vite uses Rollup internally for builds.
// rollup.config.js
import typescript from "@rollup/plugin-typescript";
export default {
input: "src/index.ts",
output: { file: "bundle.js", format: "cjs" },
plugins: [typescript()]
};Choosing bundler
Choosing: Vite for dev DX, esbuild for speed, SWC for Rust-based compilation, Rollup for control. All integrate with TS easily.
Question
Quick check: Which bundler uses native ES modules for fast dev server?
Recap
Recap: Vite is ESM-fast, esbuild is Go-speed, SWC is Rust-fast, Rollup is flexible. Use depending on project needs.
