Course Description

A database is the backbone of any application, and for developers working with varied and sizable data sets, selecting an appropriate data store is a critical development consideration. Redis, an in-memory, key-value data store offers simplified, rapid data access, valuable in a range of situations where instant access is necessary, for example with data caching.

Learning Redis is an example-based introduction which demonstrates how to work with the data store by creating a playable word game, written in NodeJs. Fundamental topics of Redis are covered along the way.

You’ll see how simple it is to install the database on your own machine or use a database provider in the cloud. Together we will discover the basic native data types of Redis and how to use them as we write a real game using JavaScript in a NodeJs environment. We’ll store and retrieve data using the Redis CLI and understand the basic NoSQL data keys and storage techniques.

Whether you’re writing a game or any other application, you need a place to store data. Learning Redis will demonstrate why you should implement Redis.

Throughout the course, we will put to use the important concepts of Redis such as keys, values, sets, and hashes, which will help us build a solid application that works on some of the most important app requirements such as information storage, validation, pub/sub, notifications, and sorting.

By the end of the course, you will understand how to make use of all of Redis’ features so you can design applications with rapid, efficiently managed data access.

  • Explore Redis commands and make the most of the supplied toolset
  • Install Redis for use on a machine or on the cloud
  • Use Redis interactively through its command line interface (CLI)
  • Efficiently tackle application complexity using Redis data structures
  • Store, list, and sort data with Redis to help create dynamic applications
  • Make the most of the Redis data store by developing an exciting word game with Node.js
  • Set up and use a hosted Redis database for increased scalability
  • Validate and notify your players using the pub/sub mechanism

Who is the target audience?

  • This course employs an example-based approach to learning, demonstrating the core topics of Redis through the development of a game and grounding the learning journey in a practical development experience.

Section 1: Course Introduction

Explain the requirements and the purpose of the course.


Explain the game that will be created.

Section 2: Getting Started

How to get Redis installed and running on your local machine.


Using a remote Redis service when a local install isn't available.


How to use Redis interactively from the command line.

Section 3: Keys and Values

How to store and retrieve basic data.


How using a key-based store affects database design and retrieval of information.

Section 4: A Game Needs Players

What is a player in our game and how can we model it.


Getting started with coding the game.


Understanding good security design.

Section 5: Building a Word Dictionary

We need a dictionary of words to validate game plays.


Getting a dictionary of words into Redis and coding the word validation check.

Section 6: Modeling the Game

Understanding the game play and user interaction.


Getting the basic game stored in Redis.


We need a bag of tiles for the user to draw letters from.

Section 7: Taking a Turn

Each player must maintain a Tray of tiles. How can we model this in Redis.


We must validate a turn against the dictionary, the player's tray, and the previous play.


A game is a series of turns by players that we need to manage.

Section 8: Game Over and Winners

We need to understand how a sorted set works to implement a leaderboard.


We need to detect the end of game and mark it as complete.


We need to calculate and store the final game results.


We want to have a leaderboard to see the top 10 scores of all time.

Section 9: Is It My Turn?

We need to learn how to use events to inform players about the status.


We need to design an event that informs our users about the game state.


We need to integrate our pub/sub design into our codebase.


We need to subscribe to the events we created.

Section 10: Wrapping Up

We want to review what you have done and learned.


We want to explore the possibilities of what we can do.
