A starter app for testing out your Apache Kafka deployment and trying out the Vert.x Kafka client.
The app allows you to send records to a topic in Kafka called demo every two seconds and consume back those records.
Test out the app by connecting to the websocket endpoints (UI will be added soon!):
- Make sure Kafka is running locally. (You can use the quickstart guide)
- Build the app:
mvn package - Start the app:
java -jar target/demo-all.jar - Connect to
http://localhost:8080/to view the UI - Use the buttons in the UI to produce and consume records
To configure the application to connect to your Kafka edit the properties file called kafka.properties.
Alternatively you can provide a custom path to the properties file using -Dproperties_path=<path> when starting the application.
If your Kafka is secured you will need to enable the security configuration options in your properties file.
To increase the logging level to debug provide a system property at start time: -Dlog.level=debug.
To increase the Kafka client logging level to info provide a system property at start time: -Dlog.level.kafka=info.
To build this project you will need:
This repo makes use of Netlify and Dependabot.
We use Netlify to show previews of Storybooks when a change is made to the UI. This is so we can see the changes without having to worry about pulling down every branch. The configuration for this lives in netlify.toml. This specifies how to build a Storybook and the project folder the UI lives in.
We use Dependabot to make sure we are always keeping our Node and Maven dependencies as up to date as possible. The configuration for this lives in .dependabot/config.yml. This describes how often we want our dependencies updates and certain restrictions such as the number of pull requests the bot can make at any one time.
