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:

• RESTEasy to expose the REST endpoints and documented with OpenAPI
• Hibernate ORM with Panache to perform the CRUD operations on the database
• PostgreSQL database; automatically starts an embedded DB
• Liquibase to automatically update database
• Quinoa to handle allowing this monorepo to serve React and Java code
• React + PrimeReact for a top notch user interface including lazy datatable
• TanStack Query for powerful asynchronous state management for TypeScript
• Orval to generate TanStack Query client Typescript from OpenAPI definition
• React Hook Forms to validate user input data

To compile and run this demo you will need:

• JDK 17+
• Docker

In addition, you will need either a PostgreSQL database, or Docker to run one.

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.

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

First compile it:

$ ./mvnw package

Connection properties for the Agroal datasource are defined in the standard Quarkus configuration file, src/main/resources/application.properties.

Then run it with:

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

Navigate to: http://localhost:8080/

💡 Have a look at how fast it boots. Or measure total native memory consumption...

You can also create a native executable from this application without making any source code changes. A native executable removes the dependency on the JVM: everything needed to run the application on the target platform is included in the executable, allowing the application to run with minimal resource overhead.

Compiling a native executable takes a bit longer, as GraalVM performs additional steps to remove unnecessary codepaths. Use the native profile to compile a native executable:

$ mvn -Pnative

After getting a cup of coffee, you'll be able to run this binary directly where ${version} is the current project version:

$ docker run -i --rm -p 8080:8080 melloware/quarkus-primereact:${version}

💡 Please brace yourself: don't choke on that fresh cup of coffee you just got. 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.
