This package exposes a MIME_TYPES
object which provides
mappings from file extensions to MIME types. For each extension one or
more MIME types are provided, with the default type always in first
position.
import { MIME_TYPES } from "@thi.ng/mime";
MIME_TYPES.mp3
// [ 'audio/mpeg', 'audio/mp3' ]
MIME_TYPES.jpg
// [ 'image/jpeg' ]
MIME_TYPES.jpeg
// [ 'image/jpeg' ]
To simplify lookup and support a fallback type, the package also has preferredType()
function:
import { preferredType } from "@thi.ng/mime";
preferredType("mp3")
// "audio/mpeg"
// unknown file extension w/ default fallback type
preferredType("foo")
// "application/octet-stream"
// unknown file extension w/ given fallback type
preferredType("foo", "text/plain")
// "text/plain"
