I have many JS snippets and files shared across multiple projects. I have to either copy-past them into a single file for each project, or serve them as individual files on cdn. Both are bad ideas.
Is there any dependency management and build tool like Maven for JavaScript? Ideally it would take a set of js dependencies and build a single js file which can be served on cdn.
I can write a script to do that. But I’m looking to find if anything comparable to Maven exists for JS.
Update 2014: Based on answers here and my research following are most popular tools:
Bower, NPM, RequireJS, Browserify, Webpack, Grunt, Gulp
There’s RequireJS, but that’s kind of a different thing than Maven, and what you’re asking it to do is different than Maven too. There are any number of JS combiner/minifiers, like jekyll-combiner and a zillion others.
If you’re using Maven, the JavaScript Maven Tools might be of interest. If you’re not, I don’t know of a unified way to specifiy, download, combine, etc. for arbitrary build systems. Some of the node.js stuff might be useful, but I’ve never used that outside of a node.js context, so I’m not sure.
