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
