  • 0

New to JavaScript and am wondering if all JavaScript has to be “deployed” as individual .js files, or if there are ways to bundle/package multiple JS files as a component, like a Java .jar or a .NET .dll.

For instance, if I have a collection of, say, 30 JS files that make up a reusable library of JS objects and functions, is there a way to package these as a single deployable component or am I stuck copying-n-pasting all 30 files into every project where I want to use them?

What’s the norm here? Thanks in advance!

    2018 update: You can use CommonJS or ES modules and package them with an appropriate tool like Browserify, webpack, Parcel, etc.

    JavaScript can’t be compiled (before sending it to the client) of course; the closest equivalent is just to minify them, then glue all the files together. For minification, I personally like Google Closure Compiler; as for the gluing, it’s pretty easy to do with your command-line tools. For example:

    cat script1.js >> all.js
cat script2.js >> all.js
# etc.
