CommonJS modules allow two ways to define exported properties. In either case you are returning an Object/Function. Because functions are first class citizens in JavaScript they to can act just like Objects (technically they are Objects). That said your question about using the new keywords has a simple answer: Yes. I’ll illustrate… Module exports You … Read more
Well there’s no reliable way to detect running in Node.js since every website could easily declare the same variables, yet, since there’s no window object in Node.js by default you can go the other way around and check whether you’re running inside a Browser. This is what I use for libs that should work both … Read more
If you want CommonJS export behavior, you’ll need to use CommonJS directly (or use the plugin in the other answer). This behavior was removed because it caused confusion and lead to invalid ES6 semantics, which some people had relied on e.g. export default { a: ‘foo’ }; and then import {a} from ‘./foo’; which is … Read more

RequireJS implements the AMD API (source). CommonJS is a way of defining modules with the help of an exports object, that defines the module contents. Simply put, a CommonJS implementation might work like this: // someModule.js exports.doSomething = function() { return “foo”; }; //otherModule.js var someModule = require(‘someModule’); // in the vein of node exports.doSomethingElse … Read more
