\n A tiny (2.8kB) and fast utility for getting a MIME type from an extension or filename\n
\n\n\n## Features\n\n* Lightweight – 2.8kB gzip
\n _Only includes standard mime types; all experimental and vendor-specific mimetypes removed._\n\n* [Performant](#benchmarks)
\n _All lookups are O(1) with minimal processing._\n\n* Comprehensive Dictionary
\n _Generated from [`mime-db`](https://github.com/jshttp/mime-db), which aggregates the IANA, NGINX, and Apache datasets._\n\n* Customizable
\n _Exposes the `mimes` dictionary for easy additions or overrides._\n\n* Supports Native ESM and [Deno](https://deno.land/x/mrmime)
\n _Ships with CommonJS and ESM support!_\n\n\n## Install\n\n```\n$ npm install --save mrmime\n```\n\n\n## Usage\n\n```js\nimport { lookup, mimes } from 'mrmime';\n\n// Get a MIME type\n// ---\nlookup('txt'); //=> \"text/plain\"\nlookup('.txt'); //=> \"text/plain\"\nlookup('a.txt'); //=> \"text/plain\"\n\n// Unknown extension\n// ---\nlookup('.xyz'); //=> undefined\n\n// Add extension to dictionary\n// ---\nmimes['xyz'] = 'hello/world';\nlookup('xyz'); //=> \"hello/world\"\n```\n\n\n## API\n\n### lookup(input)\nReturns: `string` or `undefined`\n\n#### input\nType: `string`\n\nThe extension or filename to lookup.\n\n> **Important:**\n> * Any `input` value is cast to string, lowercased, and trimmed.\n> * If a filename or filepath is provided, only the extension will be used.\n\n\n## Benchmarks\n\n> Running on Node v16.8.0\n\n```\nLoad times:\n mrmime 0.963ms\n mime/lite 3.281ms\n mime 6.751ms\n\nBenchmark :: plain (\"ext\")\n mime x 598,849 ops/sec ±0.28% (94 runs sampled)\n mime/lite x 536,643 ops/sec ±0.11% (97 runs sampled)\n mrmime x 835,885 ops/sec ±0.20% (97 runs sampled)\n\nBenchmark :: leading (\".ext\")\n mime x 368,656 ops/sec ±0.19% (99 runs sampled)\n mime/lite x 368,318 ops/sec ±0.13% (97 runs sampled)\n mrmime x 533,643 ops/sec ±0.10% (96 runs sampled)\n\nBenchmark :: filename (\"file.ext\")\n mime x 326,907 ops/sec ±0.17% (95 runs sampled)\n mime/lite x 327,479 ops/sec ±0.12% (98 runs sampled)\n mrmime x 512,823 ops/sec ±0.12% (99 runs sampled)\n```\n\n\n## Credits\n\nOf 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.\n\nThis 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.\n\nArtwork created by [mintinol](https://www.deviantart.com/mintinol), which I found [here](https://www.deviantart.com/mintinol/art/Mr-Mime-373927920).\n\nFinally, thanks to [Tim Branyen](https://github.com/tbranyen) for donating the package name :)\n\n\n## License\n\nMIT © [Luke Edwards](https://lukeed.com)\n","_attachments":{},"homepage":"https://github.com/lukeed/mrmime#readme","bugs":{"url":"https://github.com/lukeed/mrmime/issues"},"license":"MIT"}
