Node.js module concatenation library

This library exposes a single function that concatenates Node.js modules within a project. This can be used to obfuscate an entire project into a single file. It can also be used to write client-side JavaScript code where each file is written just like a Node.js module.

npm install node-module-concat

var modConcat = require("node-module-concat"); var outputFile = "./project/concatenated.js"; modConcat("./project/index.js", outputFile, function(err, files) { if(err) throw err; console.log(files.length + " were combined into " + outputFile); });

var modConcat = require("node-module-concat");

modConcat(entryModule, outputFile, [options,] cb)

• entryModule - the path to the entry point of the project to be concatenated. This might be an index.js file, for example.
• outputFile - the path where the concatenated project file will be written.
• options - Optional. An Object containing any of the following:

  • outputStreamOptions - Options passed to fs.createWriteStream call when the outputFile is opened for writing.

  • excludeFiles - An Array of files that should be excluded from the project even if they were referenced by a require(...).

    Note: These require statements should probably be wrapped in a try, catch block to prevent uncaught exceptions.

• cb - Callback of the form cb(err, files) where files is an Array of files that have been included in the project.

• Dynamic require() statements don't work (i.e. require("./" + variable))
• require.resolve calls are not modified
• require.cache statements are not modified
