How to write a module that works with Node.js, RequireJS as well as without them

Question

I am working on a JavaScript library for JSON/XML processing. My library works in browser as well as Node.js (with xmldom and xmlhttprequest modules).<

Answer 1

This is what I ended up with:

// If the require function exists ...
if (typeof require === 'function') {
    // ... but the define function does not exists
    if (typeof define !== 'function') {
        // Assume we're in the Node.js environment
        // In this case, load the define function via amdefine
        var define = require('amdefine')(module);
        // Use xmldom and xmlhttprequests as dependencies
        define(["xmldom", "xmlhttprequest", "fs"], _jsonix_factory);
    }
    else {
        // Otherwise assume we're in the browser/RequireJS environment
        // Load the module without xmldom and xmlhttprequests dependencies
        define([], _jsonix_factory);
    }
}
// If the require function does not exists, we're not in Node.js and therefore in browser environment
else
{
    // Just call the factory and set Jsonix as global.
    var Jsonix = _jsonix_factory().Jsonix;
}
