How can I convert a multi-file node.js app to a single file?

Question

If I have a node.js application that is filled with many require statements, how can I compile this into a single .js file? I'd have to manually resolve the require statements and ensure that the classes are loaded in the correct order. Is there some tool that does this?

Let me clarify.

The code that is being run on node.js is not node specific. The only thing I'm doing that doesn't have a direct browser equivalent is using require, which is why I'm asking. It is not using any of the node libraries.

You can use webpack with target: 'node', it will inline all required modules and export everything as a single, standalone, one file, nodejs module
