Angular Fire 2

Provides dependency injection and conforms to Angular conventions, making Firebase services injectable and native to the Angular ecosystem, as shown in the example use with provideFirebaseApp and inject.

Uses RxJS observables for real-time data handling, such as collectionData for Firestore, aligning perfectly with Angular's reactive programming patterns instead of callbacks.

Includes lazy-loading for Firebase modules to reduce initial load time and zone.js wrappers for stable server-side rendering, pre-rendering, and forms, ensuring broad compatibility.

Offers deploy schematics for easy hosting on Firebase with a single command and built-in router guards for authentication, simplifying common development tasks.
