How to store objects in Node.js redis?

To store objects in Node.js redism we call the hmset method.

For instance, we write

client.hmset("hosts", "mjr", "1", "another", "23", "home", "1234");

client.hgetall("hosts", (err, obj) => {
  console.dir(obj);
});

to call hmset with the key 'hosts' and the subsequent arguments as key-value pairs.

Then we get the value with with key 'hosts' with hgetall.

We get the value from obj in the callback.
