I am in the process of writing a heavy Javascript app, which will ultimately be used by injecting one script into clients websites.

As of now I am writing all the modules in one JS file, however I am quickly finding that to be ineffective, as it feels very messy and cluttered, and I feel like the modules should all be in separate files.

My question is, what is a good approach to managing this. Should I write all the apps modules in separate files, and than compile them into one on the Server?

If it matters, I am using Node.js for my server.

    First point : don’t try to code everything in one file. Most big javascript applications contain dozens of files.

    Use some kind of makefile to concatenate your js (and css) files. And after that use a minifier (I use Google Closure Compiler). To help debug, my deployement scripts always make two versions in parallel : one non concatenated/minified and one concatenated/minified. The uncompressed version enables the development/test onsite without any deployement operation.

    This means that, as for all big application development, you need some kind of deployement toolchain to orchestrate the operations. This may be based on shell scripts, maven, ant, etc.

    Secondly : use classes (without abuse, javascript isn’t really OOP) and namespaces to clearly isolate your functions.
