Quarkus PrimeReact

If you like this project, please consider supporting me ❤️

This monorepo is a minimal CRUD service exposing a couple of endpoints over REST, with a front-end based on React so you can play with it from your browser.

While the code is surprisingly simple, under the hood this is using:

• Quarkus REST for REST API endpoints with OpenAPI documentation
• Quarkus WebSockets Next for real-time WebSocket communication
• Quarkus RESTEasy Problem for consistent REST API error handling
• Quarkus Quinoa to handle allowing this monorepo to serve React and Java code
• Hibernate ORM with Panache to perform the CRUD operations on the database
• PostgreSQL database; automatically starts an embedded DB
• Liquibase to automatically update database
• React + PrimeReact for a top notch user interface including lazy datatable
• React Hook Forms to validate user input data
• React Websocket to handle websocket connections
• TanStack Query for powerful asynchronous state management for TypeScript
• Orval to generate TanStack Query client Typescript from the OpenAPI definition

Requirements

To compile and run this demo you will need:

• JDK 17+
• Apache Maven

Code Generation

This project uses Orval to generate the TanStack Query client Typescript from the OpenAPI definition.

Developing

Live coding with Quarkus

The Maven Quarkus plugin provides a development mode that supports live coding. To try this out:

$ ./mvnw quarkus:dev

Watch as it starts up a temporary PostreSQL database just for this session. In this mode you can make changes to the code and have the changes immediately applied, by just refreshing your browser.

💡 Hot reload works add a new REST endpoint and see it update in realtime. Try it!

Now open your web browser to http://localhost:8080/ to see it in action.

Building

Run Quarkus PrimeReact in JVM mode

When you're done iterating in developer mode, you can run the application as a conventional jar file.

First compile it:

$ ./mvnw clean package

Then run it with:

$ java -jar ./target/quarkus-app/quarkus-run.jar

Or build it as a single executable JAR file (known as an uber-jar):

$ ./mvnw clean package -Dquarkus.package.type=uber-jar

Then run it with:

$ java -jar ./target/quarkus-primereact-{version}-runner.jar

Navigate to: http://localhost:8080/

Run Quarkus PrimeReact in Docker

You can easily build a Docker image of this application with the following command:

$ ./mvnw -Pdocker

You will be able to run this binary directly where ${version} is the current project version:

$ docker run -i --rm -p 8000:8000 melloware/quarkus-primereact:latest

💡 Now observe the time it took to boot, and remember: that time was mostly spent to generate the tables in your database and import the initial data.
