A simple in-memory cache. put(), get() and del()


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');
// 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

Houdini will now disappear
Houdini is null
