How to use the actioncable redis correct usage?

To successfully utilize ActionCable with Redis, we must configure the Rails application and ensure that both ActionCable and Redis are properly configured.

Here’s a step-by-step description of how to use it correctly:

1. Install and configure Redis:

   We must first install Redis on the server. Typically, we may install Redis by using a package manager or by following the installation instructions on the Redis website. Once Redis has been setup, ensure that it is up and running.

2. Configure Redis in Rails:

   We must configure ActionCable in the Rails application to utilize Redis as the message broker. Typically, this is done in the config/cable.yml file. Check that the adaptor is set to redis when we open the file.

   Depending on the arrangement, we may additionally need to supply the Redis server URL or connection information.

3. Set up Redis server URL:

   Using the url option in the config/cable.yml file, we can define the Redis server URL.

   We can use the default URL redis://localhost:6379 if we are running Redis locally on the default port. Change the URL to reflect the Redis server setup.

4. Start Redis server:

   Before beginning the Rails application, make sure the Redis server is up and running. To control the Redis process, we may use tools like redis-server or a process manager like systemd or supervisor.

5. Start Rails application:

   We may restart the Rails server or application after Redis is up and running and correctly setup in the Rails application. ActionCable will connect to Redis automatically and use it as the message broker for real-time communication.

6. Broadcasting messages:

   We may leverage ActionCable’s broadcasting features in the Rails application to deliver messages to connected clients.

   This entails building channels, implementing channel-specific logic, and sending messages to specified channels or clients through the stream_from or broadcast_to methods.

7. Scaling with multiple server instances

   Redis is essential when we need to expand the program over several server instances or processes. As Redis is an external message broker, several instances of your Rails application can connect with one another over a shared Redis server.

   All instances can communicate and broadcast messages to connected clients across various server instances as long as they are configured to utilize the same Redis server and channel names.
