LRU-memory-cache
Simple in-memory cache implementation for Node.js
Installation
npm install --save LRU-memory-cache
Usage example
var MemoryCache = require('LRU-memory-cache');
// Create cache
var cache = new MemoryCache();
// Get/set value
var val = cache.get('key'); // undefined
cache.set('key', 'value', ttl);
val = cache.get('key'); // 'value'
// Delete value
cache.delete('key');
val = cache.get('key'); // undefined
// Set value which will expire after 1 second
cache.set('key', 'new-value', 1);
setTimeout(function () {
val = cache.get('key'); // undefined
}, 1000);
cache.set('key', 'new-value', 1);
setTimeout(function () {
val = cache.get('key'); // new-value (exist)
}, 900);
setTimeout(function () {
val = cache.get('key'); // still exists
}, 900);
// each get move 'used' timestamp further. So TTL means time-from-last-use. LRU cache.
