The ultimate javascript content-type utility.
Similar to [the `mime@1.x` module](https://www.npmjs.com/package/mime), except:
- ---
Otherwise, the API is compatible with `mime` 1.x.
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```sh
$ npm install mime-types
```
All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
so open a PR there if you'd like to add mime types.
```js
var mime = require('mime-types')
```
All functions return `false` if input is invalid or not found.
Lookup the content-type associated with a file.
```js
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.
```js
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.
```js
mime.extension('application/octet-stream') // 'bin'
```
Lookup the implied default charset of a content-type.
```js
mime.charset('text/markdown') // 'UTF-8'
```
