Full-stack signals poll demo

This project is an example of building a real-time poll application using full-stack signals using Vaadin Hilla. The main branch contains the starting point for the live-coding demo while the demo branch contains the final live-coding demo.

Running the application

The project is a standard Maven project. To run it from the command line, type mvnw (Windows), or ./mvnw (Mac & Linux), then open http://localhost:8080 in your browser.

You can also import the project to your IDE of choice as you would with any Maven project.

Deploying to Production

To create a production build, call mvnw clean package -Pproduction (Windows), or ./mvnw clean package -Pproduction (Mac & Linux). This will build a JAR file with all the dependencies and front-end resources, ready to be deployed. The file can be found in the target folder after the build completes.

Once the JAR file is built, you can run it using java -jar target/myapp-1.0-SNAPSHOT.jar (NOTE, replace myapp-1.0-SNAPSHOT.jar with the name of your jar).

Deploying using Docker

To build the Dockerized version of the project, run

Once the Docker image is correctly built, you can test it locally using

docker run -p 8080:8080 poll:latest
