A tiny (2.8kB) and fast utility for getting a MIME type from an extension or filename |
|
</div> |
|
|
|
|
|
## Features |
|
|
|
* Lightweight – 2.8kB gzip<br> |
|
_Only includes standard mime types; all experimental and vendor-specific mimetypes removed._ |
|
|
|
* [Performant](#benchmarks)<br> |
|
_All lookups are O(1) with minimal processing._ |
|
|
|
* Comprehensive Dictionary<br> |
|
_Generated from [`mime-db`](https://github.com/jshttp/mime-db), which aggregates the IANA, NGINX, and Apache datasets._ |
|
|
|
* Customizable<br> |
|
_Exposes the `mimes` dictionary for easy additions or overrides._ |
|
|
|
* Supports Native ESM and [Deno](https://deno.land/x/mrmime)<br> |
|
_Ships with CommonJS and ESM support!_ |
|
|
|
|
|
## Install |
|
|
|
``` |
|
$ npm install --save mrmime |
|
``` |
|
|
|
|
|
## Usage |
|
|
|
```js |
|
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. |

## Credits |
|
|
|
Of course, a thank-you to [`mime`](https://github.com/broofa/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`](https://github.com/jshttp/mime-db), who have painstakingly maintained an amazing database for 7+ years. |
