The ultimate javascript content-type utility.
Similar to the mime@1.x
module, except:
mime-types
simply returns false
, so do
var type = mime.lookup('unrecognized') || 'application/octet-stream'
.new Mime()
business, so you could do var lookup = require('mime-types').lookup
..define()
functionality.lookup(path)
Otherwise, the API is compatible with mime
1.x.
This is a Node.js module available through the
npm registry. Installation is done using the
npm install
command:
$ npm install mime-types
All mime types are based on mime-db, so open a PR there if you'd like to add mime types.
var mime = require('mime-types')
All functions return false
if input is invalid or not found.
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
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'
Get the default extension for a content-type.
mime.extension('application/octet-stream') // 'bin'
Lookup the implied default charset of a content-type.
mime.charset('text/markdown') // 'UTF-8'
