This application was generated using JHipster 6.6.0, you can find documentation and help at https://www.jhipster.tech/documentation-archive/v6.6.0.
This is a "gateway" application intended to be part of a microservice architecture, please refer to the Doing microservices with JHipster page of the documentation for more information.
This application is configured for Service Discovery and Configuration with Consul. On launch, it will refuse to start if it is not able to connect to Consul at http://localhost:8500. For more information, read our documentation on Service Discovery and Configuration with Consul.
Before you can build this project, you must install and configure the following dependencies on your machine:
- Node.js: We use Node to run a development web server and build the project. Depending on your system, you can install Node either from source or as a pre-packaged bundle.
- Yarn: We use Yarn to manage Node dependencies. Depending on your system, you can install Yarn either from source or as a pre-packaged bundle.
After installing Node, you should be able to run the following command to install development tools. You will only need to run this command when dependencies change in package.json.
yarn install
We use yarn scripts and Webpack as our build system.
If you are using hazelcast as a cache, you will have to launch a cache server. To start your cache server, run:
docker-compose -f src/main/docker/hazelcast-management-center.yml up -d
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.
./mvnw
yarn start
Yarn is also used to manage CSS and JavaScript dependencies used in this application. You can upgrade dependencies by
specifying a newer version in package.json. You can also run yarn update and yarn install to manage dependencies.
Add the help flag on any command to see how you can use it. For example, yarn help update.
The yarn run command will list all of the scripts available to run for this project.
Congratulations! You've selected an excellent way to secure your JHipster application. If you're not sure what OAuth and OpenID Connect (OIDC) are, please see What the Heck is OAuth?
To log in to your app, you'll need to have Keycloak up and running. The JHipster Team has created a Docker container for you that has the default users and roles. Start Keycloak using the following command.
docker-compose -f src/main/docker/keycloak.yml up
The security settings in src/main/resources/application.yml are configured for this image.
spring:
...
security:
oauth2:
client:
provider:
oidc:
issuer-uri: http://localhost:9080/auth/realms/jhipster
registration:
oidc:
client-id: web_app
client-secret: web_appIf you'd like to use Okta instead of Keycloak, you'll need to change a few things. First, you'll need to create a free developer account at https://developer.okta.com/signup/. After doing so, you'll get your own Okta domain, that has a name like https://dev-123456.okta.com.
Modify src/main/resources/application.yml to use your Okta settings.
spring:
...
security:
oauth2:
client:
provider:
oidc:
issuer-uri: https://{yourOktaDomain}/oauth2/default
registration:
oidc:
client-id: {clientId}
client-secret: {clientSecret}
security:Create an OIDC App in Okta to get a {clientId} and {clientSecret}. To do this, log in to your Okta Developer account and navigate to Applications > Add Application. Click Web and click the Next button. Give the app a name you’ll remember, specify http://localhost:8080 as a Base URI, and http://localhost:8080/login/oauth2/code/oidc as a Login Redirect URI. Click Done, then Edit and add http://localhost:8080 as a Logout redirect URI. Copy and paste the client ID and secret into your application.yml file.
Create a ROLE_ADMIN and ROLE_USER group and add users into them. Modify e2e tests to use this account when running integration tests. You'll need to change credentials in src/test/javascript/e2e/account/account.spec.ts and src/test/javascript/e2e/admin/administration.spec.ts.
Navigate to API > Authorization Servers, click the Authorization Servers tab and edit the default one. Click the Claims tab and Add Claim. Name it "groups", and include it in the ID Token. Set the value type to "Groups" and set the filter to be a Regex of .*.
After making these changes, you should be good to go! If you have any issues, please post them to Stack Overflow. Make sure to tag your question with "jhipster" and "okta".
JHipster ships with PWA (Progressive Web App) support, and it's turned off by default. One of the main components of a PWA is a service worker.
The service worker initialization code is commented out by default. To enable it, uncomment the following code in src/main/webapp/index.html:
<script>
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('./service-worker.js').then(function() {
console.log('Service Worker Registered');
});
}
</script>Note: Workbox powers JHipster's service worker. It dynamically generates the service-worker.js file.
For example, to add Leaflet library as a runtime dependency of your application, you would run following command:
yarn add --exact leaflet
To benefit from TypeScript type definitions from DefinitelyTyped repository in development, you would run following command:
yarn add --dev --exact @types/leaflet
Then you would import the JS and CSS files specified in library's installation instructions so that Webpack knows about them: Edit src/main/webapp/app/vendor.ts file:
import 'leaflet/dist/leaflet.js';
Edit src/main/webapp/content/scss/vendor.scss file:
@import '~leaflet/dist/leaflet.css';
Note: There are still a few other things remaining to do for Leaflet that we won't detail here.
For further instructions on how to develop with JHipster, have a look at Using JHipster in development.
You can also use Angular CLI to generate some custom client code.
For example, the following command:
ng generate component my-component
will generate few files:
create src/main/webapp/app/my-component/my-component.component.html
create src/main/webapp/app/my-component/my-component.component.ts
update src/main/webapp/app/app.module.ts
To build the final jar and optimize the gateway application for production, run:
./mvnw -Pprod clean verify
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 target/*.jar
Then navigate to http://localhost:8080 in your browser.
Refer to Using JHipster in production for more details.
To package your application as a war in order to deploy it to an application server, run:
./mvnw -Pprod,war clean verify
To launch your application's tests, run:
./mvnw verify
Unit tests are run by Jest and written with Jasmine. They're located in src/test/javascript/ and can be run with:
yarn test
For more information, refer to the Running tests page.
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
You can run a Sonar analysis with using the sonar-scanner or by using the maven plugin.
Then, run a Sonar analysis:
./mvnw -Pprod clean verify sonar:sonar
If you need to re-run the Sonar phase, please be sure to specify at least the initialize phase since Sonar properties are loaded from the sonar-project.properties file.
./mvnw initialize sonar:sonar
or
For more information, refer to the Code quality page.
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 mariadb database in a docker container, run:
docker-compose -f src/main/docker/mariadb.yml up -d
To stop it and remove the container, run:
docker-compose -f src/main/docker/mariadb.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:
./mvnw -Pprod verify jib:dockerBuild
Then run:
docker-compose -f src/main/docker/app.yml up -d
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.
To configure CI for your project, run the ci-cd sub-generator (jhipster ci-cd), this will let you generate configuration files for a number of Continuous Integration systems. Consult the Setting up Continuous Integration page for more information.
