# Event-Driven application example
This is an example Event-Driven application written in Go, using [Watermill](https://github.com/ThreeDotsLabs/watermill).
The projects aims to integrate incoming GitHub webhooks with Grafana and Slack, essentially adding annotations and
sending messages when a new commit is pushed. There are also simulated deployment messages sent over RabbitMQ to
demonstrate working with multiple event streams.
An example result can look like this:


## Running
If you'd like to integrate the example with your Slack workspace, copy `.env-example` to `.env` and fill in the
webhook URL in `SLACK_WEBHOOK_URL` variable.In addition to the application, the docker-compose environment consists of:
* **Kafka** and **ZooKeeper**
* **RabbitMQ**
* **Grafana**
* **Prometheus**The whole environment can be run with:
```bash
docker-compose up
```You can now configure your GitHub repository to send webhooks to the application (you need to expose port `8080` to the
external network first).Alternatively, you can run `./scripts/send-stub-webhook.sh` to send some stub webhooks.
Visit [localhost:3000/d/webhooks](http://localhost:3000/d/webhooks) to see annotations added in Grafana. Use
`admin:secret` as credentials.## Metrics
You can access the Watermill dashboard at [localhost:3000/d/watermill](http://localhost:3000/d/watermill). See what
changes when you send more webhooks over time.
