node-module-concat

Node.js module concatenation library

What is it?

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.

Install

npm install node-module-concat

Usage

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);
});

API

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.

  • includeNodeModules - Set to true if node_modules should also be included in the project.

• cb - Callback of the form cb(err, files, nativeModules) where files is an Array of files that have been included in the project and nativeModules is an Array of native modules that were found (but not included) when scanning the project.

Known limitations

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