The Annotated source code is available.

 
// Include the module 
var kache = require('kache');
 
// Set some options - these are the defaults 
var options = {
  start: true,    // Start a timer to remove old cache entries. 
  interval: 300   // Time in seconds between each scan. 
};
 
// Create a new cache 
var cache = kache(options);
 
// Set 'hello' to 'hello world' - expires in 3 seconds 
cache.set('hello', 'world', 3);
 
// Get 'hello' from the cache and log to console 
console.log(cache.get('hello')); // Outputs: 'world' 
 
// Wait 5 seconds and try again. The item will have expired and is no longer available. 
setTimeout(function() {
  console.log(cache.get('hello')); // null 
}, 5000);
