simple-memcached v1.0.1

simple-memcached

A Node.js package that act like a cache system,similarily redis cache and memcached do. But this one too simple to use.

Usage

First, install the package using npm:

npm install simple-memcached --save

Then, require the package and use it like so:

var simpleCache = require('simple-memcached');

And get data from cache with this simple function call:

simpleCache.getFromCache("get_all_data");

In this case, get_all_data is the key to get cached data.
And also set data from database to cache like this:

simpleCache.setCache("get_all_data", result, 60);

In this case, get_all_data is the key and result is data returned from database. 60 is the expiry time in seconds for that cache.

Check this usage sample too;

exports.get_all_data = function (cb) {
    var get_all_data = simpleCache.getFromCache("get_all_data");
    if(get_all_data !== null){
        cb(null, {status:200,desc:'success from cache', data: get_all_data});
        return;
    }
    var query = "SELECT * FROM table WHERE 1=1";
    db.getConnection(function (err, connection) {
        if(err){
            cb(err);
        }else{
            connection.query(query, function (err, result) {
                connection.release();
                if (err) {
                    cb(err);
                } else {
                    simpleCache.setCache("get_all_data", result, 60);
                    cb(null,{status:200,desc:'success from db', data: result});
                }
            });
        }
    });
}

To delete specific cache data, call following function:

simpleCache.deleteCache("get_all_data");

In this case, get_all_data is key name to delete from cache

To clear all cache once, call following function:

simpleCache.clearCache();
