Vite vs Webpack — Which Build Tool Should You Use?

#vite #webpack #comparison #tooling

Quick Comparison

	Vite	Webpack
Dev server	Instant (native ESM)	Slower (bundling)
HMR	Near-instant	Slower
Config	Minimal	Verbose
Production build	Rollup	Webpack
Plugin ecosystem	Growing	Massive
Learning curve	Low	High

When to Use Vite

New projects (it's the default for React, Vue, Svelte)
You want fast dev server startup
You don't need complex Webpack-specific plugins
You value simplicity

When to Use Webpack

Legacy projects already using Webpack
You need Module Federation (micro-frontends)
You need a specific Webpack plugin with no Vite equivalent
Complex custom build pipelines

Key Differences

Dev Server: Vite serves files over native ESM — no bundling during development. This means instant server start regardless of app size. Webpack bundles everything before serving, which gets slower as your app grows.

Configuration: A Vite config is typically 10-20 lines. A Webpack config can be hundreds of lines with loaders, plugins, and optimization settings.

Production: Vite uses Rollup for production builds, which produces smaller bundles. Webpack uses its own bundler.
