Hi Andy,
If you want to disable caching of all js files, you can do so by making the
following simple change to base.htm (starting at line 87 in the current
default branch):
require.config({
urlArgs: "cache_bust=" + Date.now(),
baseUrl: '{{ STATIC_URL }}js',
paths: {
'plugins': '{{ STATIC_URL }}plugins',
The highlighted line is the relevant bit which I added. It basically just
does what you described above, that is, it appends a timestamp to the query
string each time requirejs loads a new file, so that to the browser it
looks like a different URL and prevents caching (a practice known as 'cache
busting').
Hope that helps!
