+# quick-lru [![Build Status](https://travis-ci.org/sindresorhus/quick-lru.svg?branch=master)](https://travis-ci.org/sindresorhus/quick-lru) [![Coverage Status](https://coveralls.io/repos/github/sindresorhus/quick-lru/badge.svg?branch=master)](https://coveralls.io/github/sindresorhus/quick-lru?branch=master)
+
+> Simple [“Least Recently Used” (LRU) cache](https://en.m.wikipedia.org/wiki/Cache_replacement_policies#Least_Recently_Used_.28LRU.29)
+
+Useful when you need to cache something and limit memory usage.
+
+Inspired by the [`hashlru` algorithm](https://github.com/dominictarr/hashlru#algorithm), but instead uses [`Map`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Map) to support keys of any type, not just strings, and values can be `undefined`.
+
+## Install
+
+```
+$ npm install quick-lru
+```
+
+## Usage
+
+```js
+const QuickLRU = require('quick-lru');
+
+const lru = new QuickLRU({maxSize: 1000});
+
+lru.set('🦄', '🌈');
+
+lru.has('🦄');
+//=> true
+
+lru.get('🦄');
+//=> '🌈'
+```
+
+## API
+
+### new QuickLRU(options?)
+
+Returns a new instance.
+
+### options
+
+Type: `object`
+
+#### maxSize
+
+*Required*\
+Type: `number`
+
+The maximum number of items before evicting the least recently used items.
+
+#### maxAge
+
+Type: `number`\
+Default: `Infinity`
+
+The maximum number of milliseconds an item should remain in cache.
+By default maxAge will be Infinity, which means that items will never expire.
+
+Lazy expiration happens upon the next `write` or `read` call.
+
+Individual expiration of an item can be specified by the `set(key, value, options)` method.
+
+#### onEviction
+
+*Optional*\
+Type: `(key, value) => void`
+
+Called right before an item is evicted from the cache.
+
+Useful for side effects or for items like object URLs that need explicit cleanup (`revokeObjectURL`).
+
+### Instance
+
+The instance is [`iterable`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Iteration_protocols) so you can use it directly in a [`for…of`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Statements/for...of) loop.
+
+Both `key` and `value` can be of any type.
+
+#### .set(key, value, options?)
+
+Set an item. Returns the instance.
+
+Individual expiration of an item can be specified with the `maxAge` option. If not specified, the global `maxAge` value will be used in case it is specified on the constructor, otherwise the item will never expire.
+
+#### .get(key)
+
+Get an item.
+
+#### .has(key)
+
+Check if an item exists.
+
+#### .peek(key)
+
+Get an item without marking it as recently used.
+
+#### .delete(key)
+
+Delete an item.
+
+Returns `true` if the item is removed or `false` if the item doesn't exist.
+
+#### .clear()
+
+Delete all items.
+
+#### .resize(maxSize)
+
+Update the `maxSize`, discarding items as necessary. Insertion order is mostly preserved, though this is not a strong guarantee.
+
+Useful for on-the-fly tuning of cache sizes in live systems.
+
+#### .keys()
+
+Iterable for all the keys.
+
+#### .values()
+
+Iterable for all the values.
+
+#### .entriesAscending()
+
+Iterable for all entries, starting with the oldest (ascending in recency).
+
+#### .entriesDescending()
+
+Iterable for all entries, starting with the newest (descending in recency).
+
+#### .size
+
+The stored item count.
