mime-types 2.1.35

Mime-types is a content-type utility in JavaScript. It precisely offers its services due to its feature of not falling back naively to the first available type. Instead, when a file type is unrecognized, it returns 'false'. It is a node.js module available via npm registry and all its types are rooted in mime-db. It provides various API functionalities such as looking up the content-type associated with a file, creating a full content-type header given an extension or content-type, fetching the default extension for a content-type, checking the implied default charset of a content-type, and more.

Usage of mime-types is fairly straightforward after you've installed it using the npm install command npm install mime-types. Post-installation, you can require it in your JavaScript file with the following command var mime = require('mime-types'). The various functions provide different use cases:

• Looking up a content-type:

mime.lookup('json'); //returns 'application/json'

• Creating a full content-type header from an extension or content-type:

mime.contentType('markdown'); //returns 'text/x-markdown; charset=utf-8'

• Getting the default extension for a content-type:

mime.extension('application/octet-stream'); //returns 'bin'

• Looking up the implied default charset of a content-type:

mime.charset('text/markdown'); //returns 'UTF-8'

• A map of content-types by extension can be found at mime.types[extension] and a map of extensions by content-type at mime.extensions[type].
