How do I connect my Heroku app to Redis?

To connect your Heroku app to Redis, you can use the Heroku Redis add-on. First, run heroku addons:create heroku-redis in your terminal.

What do I do after I add the Redis add-on?

After adding the Redis add-on, you can access your Redis instance using the environment variable REDIS_URL. Use a Redis client to connect.

Can you show me an example of how to use the Redis client in my app?

Sure! If you're using Node.js, you can use the redis package. Here's a simple example:

const redis = require('redis');
const client = redis.createClient(process.env.REDIS_URL);

client.on('connect', () => {
  console.log('Connected to Redis');
});

What if I encounter connection issues?

If you encounter connection issues, check your REDIS_URL and ensure that your Redis instance is running. You can also check Heroku logs for errors.
