# Introduction
This is a sample Phoenix Application for demo connecting to Kafka. To see it in action, you can checkout the video here: https://youtu.be/Xwl0MKCnL_Y
## Features
- Setup local development environment using Docker Compose.
- [Kowl](https://github.com/cloudhut/kowl) explore Kafka messages.
- [Kaffe](https://github.com/spreedly/kaffe) Kafka client library for Phoenix projects.
## Up and running
Just run docker-compose up.
```bash
docker compose up
```
## Some useful command:
**Create a topic**
```bash
docker compose exec kafka \
kafka-topics --create --topic emails --partitions 1 --replication-factor 1 --if-not-exists --zookeeper zookeeper:2181
```
Or create multiple topics:
```bash
docker-compose exec kafka \
bash -c "seq 42 | kafka-console-producer --request-required-acks 1 --broker-list localhost:29092 --topic foo && echo 'Produced 42 messages.'"
```
**Describe topic**
```bash
docker compose exec kafka \
kafka-topics --describe --topic foo --zookeeper zookeeper:2181
```
**List messages in the topic**
```bash
docker compose exec kafka kafka-console-consumer --bootstrap-server localhost:29092 --topic emails --from-beginning
```
