API

import { format, parse, ContentType, Parameters }  from "https://deno.land/x/content_type/mod.ts";

parse(str: string): ContentType

let obj = parse('image/svg+xml; charset=utf-8');

Parse a Content-Type header. This will return an object with the following properties (examples are shown for the string 'image/svg+xml; charset=utf-8'):

  • type: The media type (the type and subtype, always lower case). Example: 'image/svg+xml'

  • parameters: An object of the parameters in the media type (name of parameter always lower case). Example: {charset: 'utf-8'}

Throws a TypeError if the string is missing or invalid.

format(obj: ContentType): string

let str = format({
  type: 'image/svg+xml',
  parameters: { charset: 'utf-8' }
});

Format an object into a Content-Type header. This will return a string of the content type for the given object with the following properties (examples are shown that produce the string 'image/svg+xml; charset=utf-8'):

  • type: The media type (will be lower-cased). Example: 'image/svg+xml'

  • parameters: An object of the parameters in the media type (name of the parameter will be lower-cased). Example: {charset: 'utf-8'}

Throws a TypeError if the object contains an invalid type or parameter names.
