schedule-cache

Installation

npm install schedule-cache --save

Usage

var Cache = require("schedule-cache");
var cache = Cache.create();
 
// 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("dapigu", "roar", 100, function(key, value) {
    console.log(key + " did " + value);
}); // Time in ms
 
console.log("Dapigu will now " + cache.get("dapigu"));
 
setTimeout(function() {
    console.log("Dapigu is " + cache.get("dapigu"));
}, 200);
 
// create new cache instance
var newCache = Cache.create();
 
newCache.put("foo", "newbaz");
 
setTimeout(function() {
    console.log("foo in old cache is " + cache.get("foo"));
    console.log("foo in new cache is " + newCache.get("foo"));
}, 200);

which should print

bar
dapigu will now roar
Dapigu did roar
Dapigu is null
foo in old cache is baz
foo in new cache is newbaz

Or schedule style

// Per Minute Clear Cache
cache.put("foo1", "minute", "*/1 * * * *", function (key, value) {
    console.log("Per " + value + "Cache");
});
 
// Per Second Clear Cache
cache.put("foo1", "second", "*/1 * * * * *", function (key, value) {
    console.log("Per " + value + "Cache");
});

which should print

Per second Cache
Per minute Cache
