What is up with version 2.4.1? about mimetypes HOT 6 CLOSED

Hi @drasive! 👋🏻

The version was pushed in a hurry and the commit was never pushed properly to GitHub. It's there now; 8942472.

Sorry about that 😅

Yeah, I noticed that. Honestly, this package just picks the first media type from mime-db's list. I guess I'll have to introduce a way to override certain media types, unless we can find a good heuristic for which to pick by default.

The other day I started a discussion about GitHub Pages' handling of .mp4 files because I think video/mp4 is a more sensible default.

(hi from Pages team). I tend to agree. I have a PR open internally to prefer video/mp4 for .mp4 extensions. This would have the side effect of making the user have to use a different extension for application/mp4, but since the latter is newer that feels more practical to me since it doesn't break long-standing assumptions about .mp4 files being videos. If there's no objections I'll change it on the Pages side at least.

The differences between the code released and the code in this repository are not backwards compatible. E.g. getting the MIME type for a file with ".mp4" extension returns "application/mp4" in v2.4.1 instead of "video/mp4".

mp4 is officially registered with IANA as application/mp4. See jshttp/mime-db#207

Hi @khellang, mp4 is also registered with IANA as video/mp4, so mime-db has multiple entries associated with .mp4 in its DB. I believe consumers of mime-db need some logic to decide which one has precedence. I noticed mime-score seems to prefer application/ but I'm not sure why.

The other day I started a discussion about GitHub Pages' handling of .mp4 files because I think video/mp4 is a more sensible default. If my understanding is wrong I'd be happy to learn more!

(Just commenting here because I haven't seen many other discussions about this recent change to mime-db. I expect this will cause more things to break once there is a new release of mime-db)

Excellent! Hope your PR is accepted!
