Bundlers

Bundlers play a crucial role in modern TypeScript development, transforming modular code into optimized JavaScript that can run efficiently in the browser or on a server. They handle features like module resolution, tree shaking, code splitting, and asset optimization, making it easier to manage dependencies and improve performance.

This tutorial covers the most popular bundlers used in the TypeScript ecosystem.

webpack

The most widely used bundler, known for its powerful plugin system, tree shaking, and hot module replacement.

esbuild

A high-performance bundler written in Go, designed for speed and efficient TypeScript transpilation.

Rollup

A minimalist bundler focused on producing optimized, tree-shaken ESM bundles, commonly used for libraries.

Parcel

A zero-config bundler with built-in support for TypeScript, making it great for fast prototyping.

Vite

A next-gen build tool leveraging esbuild for fast development and Rollup for production builds.
