Afterwards, execute npm install -g @angular/cli to install the Angular CLI globally.
Run ng serve to start the web application. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.
Configure the following headers in the web server:
content-security-policy: script-src 'self'; object-src 'none';
