A simple in-memory cache for node.js

npm install memory-cache

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', 'disappear', 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 disappear
Houdini is null
