the following dependencies on your machine: - -1. [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. - -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](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. - - ./mvnw - npm start - -Npm 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](package.json). You can also run `npm update` and `npm install` to manage dependencies. -Add the `help` flag on any command to see how you can use it. For example, `npm help update`. - -The `npm run` command will list all of the scripts available to run for this project. - -### Service workers - -Service workers are commented by default, to enable them please uncomment the following code. - -- The service worker registering script in index.html - -```html - -``` - -Note: workbox creates the respective service worker and dynamically generate the `service-worker.js` - -### Managing dependencies - -For example, to add [Leaflet][] library as a runtime dependency of your application, you would run following command: - - npm install --save --save-exact leaflet - -To benefit from TypeScript type definitions from [DefinitelyTyped][] repository in development, you would run following command: - - npm install --save-dev --save-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](src/main/webapp/app/vendor.ts) file: - -``` -import 'leaflet/dist/leaflet.js'; -``` - -Edit [src/main/webapp/content/css/vendor.css](src/main/webapp/content/css/vendor.css) file: - -``` -@import '~leaflet/dist/leaflet.css'; -``` - -Note: there are still 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][]. - -### Using angular-cli - -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 - -## Building for production - -To optimize the Bookstore application for production, run: - - ./mvnw -Pprod clean package - -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/*.war - -Then navigate to [http://localhost:8080](http://localhost:8080) in your browser. - -Refer to [Using JHipster in production][] for more details. - -## Testing - -To launch your application's tests, run: - - ./mvnw clean test - -### Client tests - -Unit tests are run by [Jest][] and written with [Jasmine][]. They're located in [src/test/javascript/](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 -``` - -Then, run a Sonar analysis: - -``` -./mvnw -Pprod clean test sonar:sonar -``` - -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](src/main/docker) folder to launch required third party services. - -For example, to start a mysql database in a docker container, run: - - docker-compose -f src/main/docker/mysql.yml up -d - -To stop it and remove the container, run: - - docker-compose -f src/main/docker/mysql.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 package -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. - -## Continuous Integration (optional) - -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.
