A PWA (Progressive Web App) with Ionic 4, Anuglar, firebase with @angular/fire

Angular is a TypeScript-based open-source framework by Google for building dynamic single-page applications and cross-platform mobile apps with MVC architecture and a rich set of features.
Firebase offers a comprehensive set of features, including real-time database, authentication, hosting, cloud functions, storage, and more. Firebase provides an easy-to-use interface and allows developers to focus on building features rather than managing infrastructure.
A Progressive Web App (PWA) is a type of web application that uses modern web technologies to provide a native app-like experience to users, including offline functionality, push notifications, and device hardware access. PWAs can be installed on a user's home screen and launched like a traditional app, but do not require a separate app store listing or download.
TypeScript is a superset of JavaScript, providing optional static typing, classes, interfaces, and other features that help developers write more maintainable and scalable code. TypeScript's static typing system can catch errors at compile-time, making it easier to build and maintain large applications.
