node-cache
A simple in-memory cache for node.js
Installation
npm install memory-cache
Usage
var cache = require('memory-cache');
// now just use the cache
cache.put('foo', 'bar');
console.log(cache.get('foo'))
// that wasn't too interesting, here's the good part
cache.put('houdini', 'disapear', 100) // Time in ms
console.log('Houdini will now ' + cache.get('houdini'));
setTimeout(function() {
console.log('Houdini is ' + cache.get('houdini'));
}, 200);
which should print
bar
Houdini will now disapear
Houdini is null
