RequireJS seems to do something internally that caches required javascript files. If I make a change to one of the required files, I have to rename the file in order for the changes to be applied.

The common trick of appending a version number as a querystring param to the end of the filename does not work with requirejs <script src=jsfile.js?v2></script>

What I am looking for is a way to prevent this internal cacheing of RequireJS required scripts without having to rename my script files every time they are updated.

Cross-Platform Solution:

I am now using urlArgs: bust= + (new Date()).getTime() for automatic cache-busting during development and urlArgs: bust=v2 for production where I increment the hard-coded version num after rolling out an updated required script.

Note:

@Dustin Getz mentioned in a recent answer that Chrome Developer Tools will drop breakpoints during debugging when Javascript files are continuously refreshed like this. One workaround is to write debugger; in code to trigger a breakpoint in most Javascript debuggers.
