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.
