mimeparse: now in JavaScript
JAVASCRIPT:
-
-
Mimeparse.bestMatch(['application/xbel+xml', 'text/xml'], 'text/*;q=0.5,*/*; q=0.1');
-
The above code is from a JavaScript port of Joe Gregorio's mimeparse library that "provides basic functions for handling mime-types. It can handle matching mime-types against a list of media-ranges. See section 14.1 of the HTTP specification RFC 2616 for a complete explanation."
Using it you can do things such as:
- parse_mime_type(): Parses a mime-type into its component parts.
- parse_media_range(): Media-ranges are mime-types with wild-cards and a 'q' quality parameter.
- quality(): Determines the quality ('q') of a mime-type when compared against a list of media-ranges.
- quality_parsed(): Just like quality() except the second parameter must be pre-parsed.
- fitness_and_quality_parsed(): Just like quality_parsed() but also returns the fitness score.
- best_match(): Choose the mime-type with the highest fitness score and quality ('q') from a list of candidates.
I have a feeling that one day we will look around and realise that we actually have a JavaScript library after all, and that server side JavaScript can do the trick :)

I’m not really sure what the applicable use of this on the client layer would be, after all to determine the mimetype of a file you’d likely be feeding that from the server side… Or am I missing something?
You are missing something. This is for rich internet applications.
