A toy CRUD application for managing prescriptions, drugs, doctors and patients.
NOTES:
- I'm experimenting with rapid app generation using AI assistants and code generators.
- This is one part of a multi-project pathfinding effort.
WHAT I DID:
- Used ChatGPT to create JDL from a brief domain description
- Used the JDL to generate a Spring Boot/Angular application with JHipster
- Modified the MapStruct mappers, the TypeScript models, and the Angular components to add more fields to the Prescription list screen.
EXAMPLE PAGE (my additions to the stock JHipster app are highlighted):
This application was generated using JHipster 7.9.3, you can find documentation and help at https://www.jhipster.tech/documentation-archive/v7.9.3.
Node is required for generation and recommended for development. package.json is always generated for a better development experience with prettier, commit hooks, scripts and so on.
In the project root, JHipster generates configuration files for tools like git, prettier, eslint, husky, and others that are well known and you can find references in the web.
/src/* structure follows default Java structure.
-
.yo-rc.json- Yeoman configuration file JHipster configuration is stored in this file atgenerator-jhipsterkey. You may findgenerator-jhipster-*for specific blueprints configuration. -
.yo-resolve(optional) - Yeoman conflict resolver Allows to use a specific action when conflicts are found skipping prompts for files that matches a pattern. Each line should match[pattern] [action]with pattern been a Minimatch pattern and action been one of skip (default if ommited) or force. Lines starting with#are considered comments and are ignored. -
.jhipster/*.json- JHipster entity configuration files -
npmw- wrapper to use locally installed npm. JHipster installs Node and npm locally using the build tool by default. This wrapper makes sure npm is installed locally and uses it avoiding some differences different versions can cause. By using./npmwinstead of the traditionalnpmyou can configure a Node-less environment to develop or test your application. -
/src/main/docker- Docker configurations for the application and services that the application depends on
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.
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.
npm install
We use npm scripts and Angular CLI with 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. 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.
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 disabled by default. To enable it, uncomment the following code in src/main/webapp/app/app.module.ts:
ServiceWorkerModule.register('ngsw-worker.js', { enabled: false }),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/app.module.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
JHipster Control Center can help you manage and control your application(s). You can start a local control center server (accessible on http://localhost:7419) with:
docker-compose -f src/main/docker/jhipster-control-center.yml up
To build the final jar and optimize the pharmascript 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. They're located in src/test/javascript/ and can be run with:
npm 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
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 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
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:
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.
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.
