Installation and Setup

Before you begin, ensure you have Docker installed on your system. If you haven't already, download and install Docker from the official Docker website: https://www.docker.com/get-docker

Start Redis (Docker)

From the node-js-crash-course directory, start Redis using docker-compose (note: use docker-compose with the "-", not "docker compose"):

$ docker-compose up -d or docker compose up --build --wait
