Overview

Redis Event Bus module for Medusa. When installed, the events system of Medusa is powered by BullMQ and io-redis. BullMQ is responsible for the message queue and worker. io-redis is the underlying Redis client, that BullMQ connects to for events storage.

Getting started

Install the module:

yarn add @medusajs/event-bus-redis

Add the module to your medusa-config.js:

module.exports = {
  // ...
  modules: [
    {
      resolve: "@medusajs/event-bus-redis",
      options: {
        redisUrl: "redis:..",
      },
    },
  ],
  // ...
}

Configuration

The module can be configured with the following options:

Option	Type	Description	Default
redisUrl	string	URL of the Redis instance to connect to.	events-worker
queueName	string?	Name of the BullMQ queue.	events-queue
queueOptions	object?	Options for the BullMQ queue. See BullMQ's documentation.	{}
redisOptions	object?	Options for the Redis instance. See io-redis's documentation	{}

Info: See how the options are applied in the RedisEventBusService and loader.

If you do not provide a redisUrl in the module options, the server will fail to start.
