browser-mime 

MIME types that can be parsed/rendered in most browsers. The list is automatically
generated from mime-db. Manual types and
extension information is also included in src/initial-db.json.

To rebuild the JS library in dist/:

``
npm build
`

To regenerate the database:

`
npm run build-db
`

This will reproduce browser-mime-db.json
by attempting to load an empty file of every type in mime-db, and keep track of which ones Chrome was able to download
and use vs. prompting the user with a Download popup.

The mime-types project is included as a squashed subtree in mime-types/. To update the subtree code use npm run update-mime-types.

API

The API is identical too, and shares the same code as, mime-types. From their README:

`js
var mime = require('mime-types')
`

All functions return false if input is invalid or not found.

$3

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'
`

$3

Get the default extension for a content-type.

`js
mime.extension('application/octet-stream') // 'bin'
`

$3

Lookup the implied default charset of a content-type.

`js
mime.charset('text/markdown') // 'UTF-8'
``
