Write the HelloWorld NodeJS application

Create a file yb-redis-helloworld.js and add the following content to it.

const redis = require("redis")
const client = redis.createClient();

client.on("error", function (err) {
    console.log("Error " + err);
});

// Insert the user profile.
const userid = 1
client.hmset(userid, ["name", "John", "age", "35", "language", "NodeJS"], redis.print);

// Query the user profile.
client.hmget(userid, ["name", "age", "language"], redis.print);

// Close the client.
client.quit(function (err, res) {
    console.log('Exiting from quit command.');
});

Run the application

To run the application, type the following:

$ node yb-redis-helloworld.js
