Redis not emitting events

When you create a new Medusa server, Redis is disabled by default. Instead, a fake Redis server is used that allows you to start your project but does not actually emit any events.

To enable a real Redis server, you need to install Redis on your machine and configure it with Medusa.

You can learn how to install Redis in the Set Up your Development Environment documentation.

After installing it, make sure to configure your Medusa server to use Redis:

module.exports = {
  projectConfig: {
    //...
    redis_url: REDIS_URL,
  },
}

By default, Medusa connects to Redis over the URL redis://localhost:6379. If you need to change that URL, set the following environment variable:

REDIS_URL=<YOUR_REDIS_URL>
