# kafkajs-demo
## Overview
It is a simple demo project to understand the working of kafka with express servers. I have used *kafkajs* as a kafka client for nodejs and *kafdrop* to monitor kafka service.
## Set up
1) Clone the repo and install the deps.
```
git clone https://github.com/fenil3357/kafkajs-demo.git
cd kafkajs-demo
cd payment-service
npm i
cd user-service
npm i
```
2) Run the zookeeper, kafka and kafdrop using docker compose.
```
cd kafka
docker compose up
```
3) Once it is running run the *admin.js* file which will create *payment-topic* with two partitions
```
cd kafka
node admin.js
```
4) After creating the topic run the payment and user services
```
cd payment-service
npm start
cd user-service
npm start
```
5) Now trigger the api in payment service to see result
```
curl "http://localhost:3000/proceed-payment?sender=Paul&receiver=Sam&amount=1000"
```
You can see the event listened in the user service console. You can also monitor kafka through kafkdrop on port 9000.
```
# Kafka monitor
http://localhost:9000
```
