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.

```js
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

js mime.extension('text/html'); // => 'html' mime.extension('application/octet-stream'); // => 'bin'

mime.charsets.lookup()

Map mime-type to charset

js 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

```js
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.

js mime.extension('text/x-some-format'); // => 'x-sf'

mime.load(filepath)

Load mappings from an Apache ".types" format file

js mime.load('./my_project.types');
The .types file format is simple - See the types dir for examples.
