# mime Comprehensive MIME type mapping API. Includes all 600+ types and 800+ extensions defined by the Apache project, plus additional types submitted by the node.js community. ## Install Install with [npm](http://github.com/isaacs/npm): npm install mime ## 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 The following APIs allow you to add your own type mappings within your project. If you feel a type should be included as part of node-mime, see [requesting new types](https://github.com/broofa/node-mime/wiki/Requesting-New-Types). ### 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.
