mime-types

The ultimate javascript content-type utility.

Similar to node-mime, except:

• No fallbacks. Instead of naively returning the first available type, mime-types simply returns false, so do var type = mime.lookup('unrecognized') || 'application/octet-stream'.
• No new Mime() business, so you could do var lookup = require('mime-types').lookup.
• Additional mime types are added such as jade and stylus via mime-db
• No .define() functionality

Otherwise, the API is compatible.

Install

sh
$ npm install mime-types

Adding Types

All mime types are based on mime-db, so open a PR there if you'd like to add mime types.

API

js
var mime = require('mime-types')

All functions return false if input is invalid or not found.

mime.lookup(path)

Lookup the content-type associated with a file.

js
mime.lookup('json')           // 'application/json'
mime.lookup('.md')            // 'text/x-markdown'
mime.lookup('file.html')      // 'text/html'
mime.lookup('folder/file.js') // 'application/javascript'

mime.lookup('cats') // false

mime.contentType(type)

Create a full content-type header given a content-type or extension.

js
mime.contentType('markdown')  // 'text/x-markdown; charset=utf-8'
mime.contentType('file.json') // 'application/json; charset=utf-8'

// from a full path
mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'

mime.extension(type)

Get the default extension for a content-type.

js
mime.extension('application/octet-stream') // 'bin'

mime.charset(type)

Lookup the implied default charset of a content-type.

js
mime.charset('text/x-markdown') // 'UTF-8'

var type = mime.types[extension]

A map of content-types by extension.

[extensions...] = mime.extensions[type]

A map of extensions by content-type.
