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.js

SWC

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

Recap

Recap: Vite is ESM-fast, esbuild is Go-speed, SWC is Rust-fast, Rollup is flexible. Use depending on project needs.
