How to set content type of JavaScript files in Django

Question

I have a Django application, which requires several JavaScript files.

In Chrome I get the error \"Resource interpreted as Script, but transferred with MIME type text

Answer 1

I had an issue with Django serving javascript files as text/plain with the included server, which doesn't work too well with ES6 modules. I found out here that you could change file extension associations by placing the following lines in your settings.py:

#settings.py
if DEBUG:
    import mimetypes
    mimetypes.add_type("application/javascript", ".js", True)

and javascript files were now served as application/javascript.
