An optimization used to speed up consecutive function calls by caching the result of calls with identical input\n\nMemory is automatically released when an item expires.\n\n\n## Install\n\n```\n$ npm install mem\n```\n\n\n## Usage\n\n```js\nconst mem = require('mem');\n\nlet i = 0;\nconst counter = () => ++i;\nconst memoized = mem(counter);\n\nmemoized('foo');\n//=> 1\n\n// Cached as it's the same arguments\nmemoized('foo');\n//=> 1\n\n// Not cached anymore as the arguments changed\nmemoized('bar');\n//=> 2\n\nmemoized('bar');\n//=> 2\n```\n\n##### Works fine with promise returning functions\n\n```js\nconst mem = require('mem');\n\nlet i = 0;\nconst counter = async () => ++i;\nconst memoized = mem(counter);\n\n(async () => {\n\tconsole.log(await memoized());\n\t//=> 1\n\n\t// The return value didn't increase as it's cached\n\tconsole.log(await memoized());\n\t//=> 1\n})();\n```\n\n```js\nconst mem = require('mem');\nconst got = require('got');\nconst delay = require('delay');\n\nconst memGot = mem(got, {maxAge: 1000});\n\n(async () => {\n\tawait memGot('sindresorhus.com');\n\n\t// This call is cached\n\tawait memGot('sindresorhus.com');\n\n\tawait delay(2000);\n\n\t// This call is not cached as the cache has expired\n\tawait memGot('sindresorhus.com');\n})();\n```\n\n\n## API\n\n### mem(fn, [options])\n\n#### fn\n\nType: `Function`\n\nFunction to be memoized.\n\n#### options\n\nType: `Object`\n\n##### maxAge\n\nType: `number`<br>\nDefault: `Infinity`\n\nMilliseconds until the cache expires.\n\n##### cacheKey\n\nType: `Function`\n\nDetermines the cache key for storing the result based on the function arguments. By default, if there's only one argument and it's a [primitive](https://developer.mozilla.org/en-US/docs/Glossary/Primitive), it's used directly as a key, otherwise it's all the function arguments JSON stringified as an array.\n\nYou could for example change it to only cache on the first argument `x => JSON.stringify(x)`.\n\n##### cache\n\nType: `Object`<br>\nDefault: `new Map()`\n\nUse a different cache storage. Must implement the following methods: `.has(key)`, `.get(key)`, `.set(key, value)`, `.delete(key)`, and optionally `.clear()`. You could for example use a `WeakMap` instead or [`quick-lru`](https://github.com/sindresorhus/quick-lru) for a LRU cache.\n\n##### cachePromiseRejection\n\nType: `boolean`<br>\nDefault: `false`\n\nCache rejected promises.\n\n### mem.clear(fn)\n\nClear all cached data of a memoized function.\n\n#### fn\n\nType: `Function`\n\nMemoized function.\n\n\n## Tips\n\n### Cache statistics\n\nIf you want to know how many times your cache had a hit or a miss, you can make use of [stats-map](https://github.com/SamVerschueren/stats-map) as a replacement for the default cache.\n\n#### Example\n\n```js\nconst mem = require('mem');\nconst StatsMap = require('stats-map');\nconst got = require('got');\n\nconst cache = new StatsMap();\nconst memGot = mem(got, {cache});\n\n(async () => {\n\tawait memGot('sindresorhus.com');\n\tawait memGot('sindresorhus.com');\n\tawait memGot('sindresorhus.com');\n\n\tconsole.log(cache.stats);\n\t//=> {hits: 2, misses: 1}\n})();\n```\n\n\n## Related\n\n- [p-memoize](https://github.com/sindresorhus/p-memoize) - Memoize promise-returning & async functions\n\n\n## License\n\nMIT © [Sindre Sorhus](https://sindresorhus.com)\n","maintainers":[{"name":"sindresorhus","email":"sindresorhus@gmail.com"}],"time":{"modified":"2018-08-27T17:33:41.257Z","created":"2013-01-22T23:16:13.120Z","0.0.1":"2013-01-22T23:16:15.354Z","0.1.0":"2015-12-21T18:44:14.279Z","0.1.1":"2016-02-02T15:53:17.433Z","1.0.0":"2016-10-19T17:34:31.486Z","1.1.0":"2016-10-19T18:05:26.119Z","2.0.0":"2017-09-25T06:32:08.213Z","3.0.0":"2017-10-11T15:56:14.080Z","3.0.1":"2018-06-20T06:38:02.452Z","4.0.0":"2018-08-27T17:33:38.386Z"},"author":{"name":"Sindre Sorhus","email":"sindresorhus@gmail.com","url":"sindresorhus.com"},"repository":{"type":"git","url":"git+https://github.com/sindresorhus/mem.git"},"keywords":["memoize","function","mem","memoization","cache","caching","optimize","performance","ttl","expire","promise"],"readmeFilename":"readme.md","homepage":"https://github.com/sindresorhus/mem#readme","bugs":{"url":"https://github.com/sindresorhus/mem/issues"},"license":"MIT","users":{"antixrist":true,"psychollama":true,"quocnguyen":true,"sasquatch":true,"joelwallis":true,"pldin601":true,"cr8tiv":true,"daniel-zahariev":true,"xch":true},"_attachments":{},"_etag":"W/\"3481a115138c70d34c3c0700809391fc\"","_lastModified":"Mon, 27 Aug 2018 17:33:42 GMT"}
