I do not think this change is correct, it is not officially registered with IANA as required.

Thanks for the review, @StanFromIreland! I updated this PR to add the extension to common_types like you suggested

[hugovk]

IANA says .cjs is an extension for the application/node type for CommonJS modules, not text/javascript:

https://www.iana.org/assignments/media-types/application/node

See here for more information: nodejs.org/api/modules.html#enabling

And this makes no mention of the MIME type.

Thanks for the update. And because this is actually registered with IANA, we can put it in the regular list.

Please also don't force push in this repo, it makes it a bit harder to review changes. We squash merge anyway at the end.

@hugovk That's a good point about force-pushing. Thank you for your help!

Please add to the first in the mimetypes list at https://docs.python.org/3.15/whatsnew/3.15.html#mimetypes

@hugovk Oh, weird, I think my local repo had an issue because I checked out with a depth of 1 and git fetch wasn't working. I've got that sorted now and can push from my local branch normally. Thanks for your patience!

[hugovk]

Thank you!
