Description

Kafka consumer and procuder apps recipe for Mau.

This recipe is using a monorepo setup with multiple applications. Each application is a separate NestJS application. This isn't required, we just used it here for demonstration purposes.

This monorepo contains the following applications:

  1. Kafka producer
  2. Kafka consumer

Project setup

  1. Install necessary dependencies
$ npm install
$ npm install -g @nestjs/mau
  1. Create a new Mau project.
  2. Within that project, create two applications: Kafka producer and Kafka consumer.
  3. Create: Kafka broker.
  4. Now one by one, generate API keys for each application and run the following commands to deploy this recipe to the cloud:
$ npm run build APP_NAME
$ mau deploy APP_NAME

Environment variables

# Every Kafka broker comes with at least 2 nodes, hence the need for 2 URLs
KAFKA_BROKER_URL_1= # Kafka broker URL (1), example "b-1.name.ytderz.c6.kafka.us-east-1.amazonaws.com:9096"
KAFKA_BROKER_URL_2= # Kafka broker URL (2), example "b-2.name.ytderz.c6.kafka.us-east-1.amazonaws.com:9096"
KAFKA_BROKER_USERNAME= # Kafka broker username
KAFKA_BROKER_PASSWORD= # Kafka broker password
