mime
Comprehensive MIME type mapping API based on mime-db module.
Install
Install with npm:
npm install mime
Contributing / Testing
npm run test
Command Line
mime [path_string]
E.g.
> mime scripts/jquery.js
application/javascript
API - Queries
mime.lookup(path)
Get the mime type associated with a file, if no mime type is found application/octet-stream is returned. Performs a case-insensitive lookup using the extension in path (the substring after the last '/' or '.'). E.g.
var mime = require('mime');
mime.lookup('/path/to/file.txt'); // => 'text/plain'
mime.lookup('file.txt'); // => 'text/plain'
mime.lookup('.TXT'); // => 'text/plain'
mime.lookup('htm'); // => 'text/html'
mime.default_type
Sets the mime type returned when mime.lookup fails to find the extension searched for. (Default is application/octet-stream.)
mime.extension(type)
Get the default extension for type
mime.extension('text/html'); // => 'html'
mime.extension('application/octet-stream'); // => 'bin'
mime.charsets.lookup()
Map mime-type to charset
mime.charsets.lookup('text/plain'); // => 'UTF-8'
(The logic for charset lookups is pretty rudimentary. Feel free to suggest improvements.)
API - Defining Custom Types
Custom type mappings can be added on a per-project basis via the following APIs.
mime.define()
Add custom mime/extension mappings
mime.define({
'text/x-some-format': ['x-sf', 'x-sft', 'x-sfml'],
'application/x-my-type': ['x-mt', 'x-mtt'],
// etc ...
});
mime.lookup('x-sft'); // => 'text/x-some-format'
The first entry in the extensions array is returned by mime.extension(). E.g.
mime.extension('text/x-some-format'); // => 'x-sf'
mime.load(filepath)
Load mappings from an Apache ".types" format file
mime.load('./my_project.types');
The .types file format is simple - See the types dir for examples.
