mime-types

The ultimate javascript content-type utility.

Install

$ npm install mime-types

Similar to mime except:

• No new Mime() business, so you could do var lookup = require('mime-types').lookup.
• No fallbacks, so do var type = mime.lookup('unrecognized') || 'application/octet-stream'.
• Additional mime types are added such as jade and stylus. Feel free to add more!
• Browser support via Browserify and Component by converting lists to JSON files.

Otherwise, the API is compatible.

Adding Types

If you'd like to add additional types, simply create a PR adding the type to custom.json and a reference link to the sources.

Do NOT edit mime.json or node.json. Those are pulled using build.js. You should only touch custom.json.

API

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.

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.

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

mime.extension(type)

Get the default extension for a content-type.

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

mime.charset(type)

Lookup the implied default charset of a content-type.

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

mime.types[extension] = type

A map of content-types by extension.

mime.extensions[type] = [extensions]

A map of extensions by content-type.

mime.define(types)

Globally add definitions. types must be an object of the form:

{
  "<content-type>": [extensions...],
  "<content-type>": [extensions...]
}

See the .json files in lib/ for examples.
