Webpack vs Vite: What’s the Difference?

As frontend projects grow, choosing the right build tool is critical. Let’s quickly compare Webpack and Vite in 6 areas:

---

1️⃣ Architecture

	Webpack	Vite
Type	Bundler-based	Native ESM-based dev server
Dev Mode	Full bundling needed	No bundling, uses native ES modules
Prod Mode	Uses Webpack	Uses Rollup

✅ Vite = faster dev startup
✅ Webpack = full control and compatibility

---

2️⃣ Development Speed

Feature	Webpack	Vite
Cold Start	❌ Slow	✅ Super fast
HMR	❌ Can lag	✅ Instant updates
Build Time	❌ Slower	✅ Faster (ESBuild)

✅ Vite wins in speed and DX (developer experience)

---

3️⃣ Build Tools

Area	Webpack	Vite
Dev Server	webpack-dev-server	Built-in, ultra-fast
Production Bundler	Webpack	Rollup
Transpiler	Babel, ts-loader	ESBuild (dev), Rollup (prod)
TypeScript	Needs setup	Built-in, fast
Code Splitting	Manual/SplitChunks	Built-in

✅ Vite is modern & simple
✅ Webpack is powerful but complex

---

4️⃣ Plugin Ecosystem

• Webpack: ✅ Very mature, tons of plugins
• Vite: 🚀 Fast-growing, supports Rollup plugins

✅ Use Webpack for plugin flexibility
✅ Vite if you’re okay with lighter plugin use
