nodecache

Simple and powerful Cache Module for NodeJS.

Install with:

npm install nodecache

Usage

Save data in memory, the second parameter of cache.save only be called if it is not currently in memory.

var cache = require('nodecache');
 
var myFunction = function () {
    ...
    return 'Some Data';
};
var myData = cache.save('myData', myFunction); // This will call myFunction() and return 'Some Data'.
var myCachedData = cache.save('myData', myFunction); // This will return 'Some Data' without call myFunction().

Persist data using Redis:

var cache = require('nodecache');
 
var myFunction = function () {
    ...
    return 'Some Data';
};
cache.persist('myData', myFunction, function (err, reply) {
    console.log(reply); // Some Data
});

In the code above, data will be searched first in local memory, if not found there, it will be searched on Redis Storange, and if neither, it finally call myFunction().
