JavaScript Minification Tips

Library Support

• React: Preserves JSX, hooks, and component patterns

• jQuery: Maintains $ and jQuery selectors safely

• Moment.js: Keeps date formatting and manipulation methods

• DOM APIs: Preserves querySelector, addEventListener, etc.

• Modern JS: Handles async/await, fetch, and Promises

Best Practices

• Test minified code thoroughly before production

• Keep source maps for debugging

• Be cautious with variable name shortening for libraries

• Preserve license comments in library code

• Consider using specialized tools for large libraries

Safe Minification

• Library method calls are preserved automatically

• String literals remain unchanged

• Important comments (license, copyright) are kept

• Framework-specific patterns are protected

• URL patterns in comments are preserved

Performance Tips

• Remove console logs for production builds

• Use whitespace removal for maximum compression

• Enable string optimization for smaller files

• Consider semicolon removal for modern browsers

• Combine with gzip compression for best results
