mime-types (2.1.35)

2026-02-24T14:01:22Z

Setup this registry in your project .npmrc file:

registry=

To install the package using npm, run the following command:

npm install mime-types@2.1.35

or add it to the package.json file:

"mime-types": "2.1.35"

For more information on the npm registry, see the documentation.

mime-types

The ultimate javascript content-type utility.

Similar to the mime@1.x module, 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.
No .define() functionality
Bug fixes for .lookup(path)

Otherwise, the API is compatible with mime 1.x.

Install

This is a Node.js module available through the npm registry. Installation is done using the npm install command:

$ 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

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/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. When given an extension, mime.lookup is used to get the matching content-type, otherwise the given content-type is used. Then if the content-type does not already have a charset parameter, mime.charset is used to get the default charset and add to the returned content-type.

mime.contentType('markdown') // 'text/x-markdown; charset=utf-8'
mime.contentType('file.json') // 'application/json; charset=utf-8'
mime.contentType('text/html') // 'text/html; charset=utf-8'
mime.contentType('text/html; charset=iso-8859-1') // 'text/html; charset=iso-8859-1'

// 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/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.
