Persisting data with Redis

Redis is an open source in-memory key-value data store. Used in the correct setting, Redis can be a fast-performing data store. It is often used to provide caching in applications, but can also be used as a database.

In this recipe, we're going to create a task list database using Redis.

Getting ready

1. As with the previous databases in this chapter, we will use Docker to provision a Redis database using the following command:

   $ docker run --publish 6379:6379 --name node-redis --detach redis

   By default, the containerized Redis database will be available at localhost:6379.

2. We will also create a new folder named redis-app containing a file named tasks.js:

   $ mkdir redis-app
   $ cd redis-app
   $ touch tasks.js 

3. In this recipe, we will be making use of third-party npm modules; therefore, we need to initialize our project:

   $ npm init --yes

Now that we have Redis running and our project set up, we're ready to move on to the recipe.
