Minification Tips

Minifying JavaScript reduces file sizes, which means faster downloads and better page performance. Even simple whitespace removal can cut 20-40% off typical code.

Best Practices

  • Always test minified code before deploying to production
  • Use source maps for debugging minified code in production
  • Combine minification with Gzip/Brotli compression on your server
  • For modern projects, use Vite, Webpack, or Rollup with Terser
  • Keep original source files in version control, not minified ones
