Javascript module not working in browser?

Question

Alright, I have looked on this site and have found several different answers, none of which have worked for me. Basically had a js file that had many functions in it along

Answer 1

You might want to use broswerify instead. It allows you to write NodeJS-style modules and then compiles them into a single browser-friendly JavaScript file, allowing you to get all the performance benefits of loading only a single file. It also means you can easily use the same code both server side and client side.

If you want to stick with separate files, it looks like you are well on your way. Unlike regular JavaScript files, modules are subject to Cross-Origin Resource Sharing (CORS) restrictions. They have to be loaded from the same origin, and cannot be loaded from the local filesystem. If you are loading them from the local file system, move them to a server. If you are already hosting them on a server, add the Access-Control-Allow-Origin: * header to the response that serves the module file.
