API

Generated API docs

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"
