Nestjs Kafka And Kubernetes Lima S Cloud Kafka is an open source, distributed streaming platform which has three key capabilities: publish and subscribe to streams of records, similar to a message queue or enterprise messaging system. store streams of records in a fault tolerant durable way. process streams of records as they occur. the kafka project aims to provide a unified, high. Then consumers come into play, they subscribe to the desired topic, and start reading messages. each application has its own queue, reading from which the consumer moves the offset pointer.
Apache Kafka Consumers Tutorial Cloudduggu Create an nx workspace by running the following command: > npx create nx workspace@latest. specify the nest option while creating the workspace and name the application api gateway. once the workspace is created, install the project dependencies by running the following commands: > cd nestjs microservices > npm i @nestjs microservices kafkajs. To create a kafka consumer in nestjs, we can use the @nestjs microservices module and the kafkaoptions interface. here's an example: here's an example: import { kafkaoptions , transport } from ' @nestjs microservices ' ; @ injectable () export class kafkaconsumerservice { private readonly kafkaclient : clientkafka ; constructor () { this . kafkaclient = new clientkafka ({ transport : transport . Additionally, the module configures a kafka consumer with a 'groupid' labeled as 'nestjs consumer group' for efficient message consumption. this module level configuration serves as a foundation for kafka interaction throughout the application, ensuring seamless communication with kafka topics and enabling event driven and real time functionality within the nest.js framework. Okay, now it’s time for the consumer app to consume messages of fibo topic and produce a message as e result in fibo.reply topic, let’s name it consumer:. nest new consumer npm i @nestjs.

Cqrs pattern with nestjs and kafka. in this step by step guide, we will walk through the process of building a sample blog application with three microservices — two producers (auth service and blog service) and one consumer (projection service) — using nestjs, kafka, and the cqrs pattern (command query responsibility segregation). To implement kafka in nestjs, follow these steps: 1. install the @nestjs microservices and kafkajs packages using npm: 2. create a kafka module in nestjs using the nestjs generator: 3. import the kafkamodule in your main application: 4. create a kafka service in the kafkamodule:.
