client.getOrFetch('TestKeyGetFetchMC', done=>{
    setTimeout(function(){ done("This is the fetched value"); }, 3000);

let cache = require('mpnode-cache');
 
console.log("memcached");
 
let client = new cache("127.0.0.1", 6379, "redis");
 
client.set('TestKey', "TestValue")
        .then(rep => console.log(rep, "respuesta set"))
        .catch(err=>console.log(err, "error set"));
 
client.get('TestKey')
        .then(rep => console.log(rep, "respuesta get"))
        .catch(err=>console.log(err, "error get"));
 
let obj = {'att1':"val1"};
 
client.setHash("testHashKey", obj)
        .then(rep => console.log(rep, "respuesta setHashet"))
        .catch(err=>console.log(err, "error setHash"));
 
client.getHash("testHashKey")
        .then(rep => console.log(rep, "respuesta getHashet"))

The road ahead

• Replace with Spyies or Stubs both redis clients methods in unit tests

• Implement auth support
