python3 -m http.server returns wrong MIME type for javascript files causing samples not to work

[hfmanson]

in README.md it's suggested to run the samples with

python3 -m http.server

However this server returns the text/html MIME type for .js and .css files. Therefore, on Chrome the audioworklet sample does not work.

I now use this Python script, providing the correct MIME type for javascript and css files.

try:
    from http import server # Python 3
except ImportError:
    import SimpleHTTPServer as server # Python 2

if __name__ == '__main__':
    server.SimpleHTTPRequestHandler.extensions_map['.js'] = 'application/javascript'
    server.SimpleHTTPRequestHandler.extensions_map['.css'] = 'text/css'
    server.test(port=8114, HandlerClass=server.SimpleHTTPRequestHandler, protocol="HTTP/1.1")

Hi @hfmanson - thanks a lot for reporting this one.

I had a look into this, and I can't reproduce this on Firefox or Chrome. You can also check using curl to see the returned content-type:

# Python 3.11.5 (main, Aug 24 2023, 15:09:45) [Clang 14.0.3 (clang-1403.0.22.14.1)] on darwin
cd path/to/webaudio-examples/audioworklet
python3 -m http.server
# ...
curl -v localhost:8000/script.js
*   Trying 127.0.0.1:8000...
* Connected to localhost (127.0.0.1) port 8000 (#0)

It could be that this has been fixed in the meantime, but I've tested using Python 3.11.5.

I'm going to close for the moment, but if you have some other info, let me know here! Thanks a lot!

Indeed, it's a python problem: SimpleHTTP/0.6 Python/3.10.12 on Linux returns text/javascript SimpleHTTP/0.6 Python/3.10.9 on Windows returns text/plain as MIME type on a .js files

I agree on closing the issue, maybe mention python version should be at least 3.10.12

Thanks for getting back, I'm glad we got to the bottom of it.

mention python version should be at least 3.10.12

That's a good idea, we can add a note in the docs. 👍🏻
