Requirements

JHipster 7.9.3

npm install -g generator-jhipster
npm install -g yo

JDK 11

Node Js >= 14

Gradle > 7.x

Development

You need to run this command when dependencies change in package.json.

npm install

We use npm scripts and [Webpack][] as our build system.

Run the following commands in two separate terminals to create a blissful development experience where your browser auto-refreshes when files change on your hard drive.

Server:
./gradlew -x webapp

Client:
npm start

Swagger UI

http://localhost:9060/admin/docs

Building for production

Packaging as jar

To build the final jar and optimize the jhipster_demo application for production, run:

./gradlew -Pprod clean bootJar

This will concatenate and minify the client CSS and JavaScript files. It will also modify index.html so it references these new files. To ensure everything worked, run:

java -jar build/libs/*.jar

Then navigate to http://localhost:8080 in your browser.

Refer to [Using JHipster in production][] for more details.

Packaging as war

To package your application as a war in order to deploy it to an application server, run:

./gradlew -Pprod -Pwar clean bootWar

Testing

To launch your application's tests, run:

./gradlew test integrationTest jacocoTestReport

Client tests

Unit tests are run by [Jest][]. They're located in src/test/javascript/ and can be run with:

npm test

For more information, refer to the [Running tests page][].

Code quality

Sonar is used to analyse code quality. You can start a local Sonar server (accessible on http://localhost:9001) with:

docker-compose -f src/main/docker/sonar.yml up -d

Note: we have turned off authentication in src/main/docker/sonar.yml for out of the box experience while trying out SonarQube, for real use cases turn it back on.

You can run a Sonar analysis with using the sonar-scanner or by using the gradle plugin.

Then, run a Sonar analysis:

./gradlew -Pprod clean check jacocoTestReport sonarqube

For more information, refer to the [Code quality page][].

Using Docker to simplify development (optional)

You can use Docker to improve your JHipster development experience. A number of docker-compose configuration are available in the src/main/docker folder to launch required third party services.

For example, to start a postgresql database in a docker container, run:

docker-compose -f src/main/docker/postgresql.yml up -d

To stop it and remove the container, run:

docker-compose -f src/main/docker/postgresql.yml down

You can also fully dockerize your application and all the services that it depends on. To achieve this, first build a docker image of your app by running:

npm run java:docker

Or build a arm64 docker image when using an arm64 processor os like MacOS with M1 processor family running:

npm run java:docker:arm64

Then run:

docker-compose -f src/main/docker/app.yml up -d

When running Docker Desktop on MacOS Big Sur or later, consider enabling experimental Use the new Virtualization framework for better processing performance (disk access performance is worse).

For more information refer to [Using Docker and Docker-Compose][], this page also contains information on the docker-compose sub-generator (jhipster docker-compose), which is able to generate docker configurations for one or several JHipster applications.
