A tiny (2.8kB) and fast utility for getting a MIME type from an extension or filename

Features

• Lightweight – 2.8kB gzip
  Only includes standard mime types; all experimental and vendor-specific mimetypes removed.

• Performant
  All lookups are O(1) with minimal processing.

• Comprehensive Dictionary
  Generated from mime-db, which aggregates the IANA, NGINX, and Apache datasets.

• Customizable
  Exposes the mimes dictionary for easy additions or overrides.

• Supports Native ESM and Deno
  Ships with CommonJS and ESM support!

Install

$ npm install --save mrmime

Usage

import { lookup, mimes } from 'mrmime';

// Get a MIME type
// ---
lookup('txt'); //=> "text/plain"
lookup('.txt'); //=> "text/plain"
lookup('a.txt'); //=> "text/plain"

// Unknown extension
// ---
lookup('.xyz'); //=> undefined

// Add extension to dictionary
// ---
mimes['xyz'] = 'hello/world';
lookup('xyz'); //=> "hello/world"

API

lookup(input)

Returns: string or undefined

input

Type: string

The extension or filename to lookup.

Important:

• Any input value is cast to string, lowercased, and trimmed.
• If a filename or filepath is provided, only the extension will be used.

Credits

Of course, a thank-you to mime serving the community all these years & for being a all-encompassing MIME type library. I've only ever needed lookup/getType functionality – and now ESM support – so mrmime can only ever support 1/3 of what mime offers, at best.

This would not be possible without the team behind mime-db, who have painstakingly maintained an amazing database for 7+ years.

Artwork created by mintinol, which I found here.

Finally, thanks to Tim Branyen for donating the package name :)
