Implements parsing based on RFC 2045 with added support for suffixes (RFC 3023, RFC 6839).
RFC 2045 is a little more permissive than later RFCs when it comes to allowed tokens. MediumType.js thereby adheres to Postel's law of liberal acceptance.
Examples of supported media types:
Split comma separated media types (like in HTTP's
Note that it properly supports quoted parameters when splitting. It's the only library that I know of that does this.MediumType
Sort an array of
MediumTypes according to sorting rules of the HTTP
Acceptheader listed in RFC 2616 and RFC 7231.
That is, first by the
qparameter, then by type and subtype specificity and then by parameter count (excluding the
Stringify media types to a canonical
type/subtype+suffix; param=valueformat.MediumTypetype: "application" subtype: "json"
No dependencies on Node.js modules or the whole MIME database. Pretty lightweight and easily usable in the browser with Browserify.
From v1.0.0 MediumType.js will follow semantic versioning, but until then, breaking changes may appear between minor versions (the middle number).
Installing on Node.js
npm install medium-type
Installing for the browser
MediumType.js doesn't yet have a build ready for the browser, but you will be able to use Browserify to have it run there till then.
var MediumType =var type = "application/vnd.app.model+json; charset=utf-8"typetype == "application"typesubtype == "vnd.app.model"typesuffix == "json"typeparameterscharset == "utf-8"
