What are the best practices for CSS and JS minification?

Minification involves removing unnecessary characters from your CSS and JS files without changing their functionality. Best practices include using tools like UglifyJS for JavaScript and CSSNano for CSS, ensuring you have a build process in place, and testing your minified files to avoid errors.

Can you recommend some tools for minification?

Sure! For JavaScript, you can use UglifyJS, Terser, or Google Closure Compiler. For CSS, consider using CSSNano, CleanCSS, or PostCSS.

How do I integrate minification into my build process?

You can integrate minification into your build process using task runners like Gulp or Grunt, or build tools like Webpack. Set up tasks to automatically minify your files during the build.

What should I watch out for when minifying?

Be cautious of potential issues like variable name collisions, loss of comments that might be important for understanding the code, and ensuring that your minified files are properly tested to avoid runtime errors.
