Js file. There are many minifiers to choose from, including these: Google’s Closure Compiler, UglifyJS, and YUI Compressor, among others. You’ll find many online tools to help you use them, and minification-on-save is a common feature in code editors like Sublime Text, Brackets, Atom, and Light Table. Services like Grunt, Gulp, and Yeoman will also do this for you, and you can set file watchers that will concatenate and compress files for you automatically when they change. Here’s the “cave-man-style” Unix command-line way to concatenate and minify your code using UglifyJS: 1.
