Avoiding duplicate downloads

I have the issue that scripts are loaded multiple times. I would have expected that scripts that have been loaded or are in the middle of loading won’t be loaded each time.

loadjs(['libraryA.js', 'usingA.js'], {
  success: function() { /* done loading */ },
  async: false
});

loadjs(['libraryA.js', 'libraryB_usingA.js', 'usingA_B.js'], {
  success: function() { /* done loading */ },
  async: false
});

In the above example libraryA.js gets loaded twice. I’ve been trying to avoid this issue by using bundleIds and loadjs.ready but this gets complicated quite quickly.

Am I missing something here?

@groupedsi @naltatis Here’s a new lightweight dependency manager I created called JohnnyDepp that implements the require method you requested: https://github.com/muicss/johnnydepp

Let me know what you think.

Great! I’m happy to hear you like it. LoadJS and JohnnyDepp share the same underlying file loading code but their API’s are different enough that I thought combining them into one library would be confusing.

JohnnyDepp is tested across all major browsers and should be production-ready so give it a try and let me know if it works for you.
