JavaScript Minification Best Practices
Our JavaScript Minifier applies the best compression settings, but keeping these tips in mind will make your work even better:
Always Validate First
Check your code before minifying. Invalid JavaScript may break after compression.
Keep a Readable Copy
Always save a formatted version for editing and debugging. Use the minified one for live sites.
Test After Minification
Run your app after minifying. Some settings may affect functionality if not tested.
Use Source Maps
For debugging, use source maps to track minified code back to the original script.
Following these practices will help you keep your JavaScript fast, secure, and easy to maintain.
