building for production: ng build (ahead-of-time compilation)

deploying app on server:

• Use & check environment variables!!! (was done when connecting to Firebase...)
• Polish & test code
• Build app (terminal comand) - see building for production
• Deploy build artifacts (generaated files) to static host (HTML, JS, CSS) - see Firebase hosting

For Firebase hosting:

• npm install -g firebase-tools
• firebase login (sign in to Google - Firebase account)
• firebase init (initiate your project - from app root directory)
• Put your static files (e.g., HTML, CSS, JS) in your app’s deploy directory (the default is “public” - change to dist/app-name)
• firebase deploy
