mime-type

mime-type

The custom mime-typs utility can work with mime-db.

fork from mime-types, except:

• you can load mime-types via mime-db mime = new Mime(require('mime-db'))
  • or use mime = require('mime-type/with-db') directly, but first
  • you need npm install mime-db
• mime = new Mime() business, so you could do lookup = mime.lookup.bind(mime).
• you can add the mime-type via .define() functionality
• you can search the mime-type via .glob() functionality
• .exist(type) functionality to check whether a mime-type is exist.
• .extensions will be deprecated, use mime[type].extensions instead.
• All functions return undefined if input is invalid or not found.

Otherwise, the API is compatible.

Install

$ npm install mime-type

API

var mime = require('mime-type')()
//or create an instance and load mime-db. you need `npm install mime-db`
var mime = require('mime-type/with-db')

All functions return undefined 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('folder/.htaccess') // false

mime.lookup('cats') // false

mime.glob(pattern)

Return all MIME types which matching a pattern

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

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'

// 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.

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'

var type = mime.types[extension]

A map of content-types by extension.

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

A map of extensions by content-type.
