How to Integrate Angular with Spring Boot Rest API

Run ng serve --port 8081 for a dev server. Navigate to http://localhost:8081/. The app will automatically reload if you change any of the source files.

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.

Run ng build to build the project. The build artifacts will be stored in the dist/ directory.

Run ng test to execute the unit tests via Karma.

Run ng e2e to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.
