Utility functions for media types (MIME types).

This API is inspired by the GoLang mime package and jshttp/mime-types, and is designed to integrate and improve the APIs from x/media_types.

The vendor folder contains copy of the jshttp/mime-db db.json file along with its license.

import { extensionsByType } from "https://deno.land/std@0.224.0/media_types/extensions_by_type.ts";

extensionsByType("application/json"); // ["json", "map"]
extensionsByType("text/html; charset=UTF-8"); // ["html", "htm", "shtml"]
extensionsByType("application/foo"); // undefined

Variables

extensions

A map of extensions for a given media type.

Functions

f contentType	Given an extension or media type, return a full `Content-Type` or `Content-Disposition` header value.
f extension	For a given media type, return the most relevant extension, or `undefined` if no extension can be found.
f extensionsByType	Returns the extensions known to be associated with the media type `type`. When `type` has no associated extensions, the function returns `undefined`.
f formatMediaType	Serializes the media type and the optional parameters as a media type conforming to RFC 2045 and RFC 2616.
f getCharset	Given a media type or header value, identify the encoding charset. If the charset cannot be determined, the function returns `undefined`.
f parseMediaType	Parses the media type and any optional parameters, per RFC 1521. Media types are the values in `Content-Type` and `Content-Disposition` headers. On success the function returns a tuple where the first element is the media type and the second element is the optional parameters or `undefined` if there are none.
f typeByExtension	Returns the media type associated with the file extension. Values are normalized to lower case and matched irrespective of a leading `.`.

Type Aliases

T ContentTypeToExtension	Maps content types to their corresponding file extensions.
T DB	MIME-types database.
T KnownExtensionOrType	Known extension or type. Used in `contentType`.
