AngularFire is the official Angular library for Firebase. It provides Angular-native wrappers around the Firebase JS SDK with:

- **Dependency Injection** - Firebase services as injectable Angular services
- **Zone.js Integration** - Automatic zone wrapping for change detection stability
- **RxJS Observables** - Real-time data streams as Observables
- **Lazy Loading** - Dynamic imports to reduce bundle size
- **SSR Support** - Compatible with Angular Universal/SSR
- **Router Guards** - Built-in auth guards for route protection

## When to Apply

Use this skill when:

- **Setting up Firebase** in an Angular application
- Implementing **Firebase Authentication** (sign-in, sign-out, auth guards)
- Working with **Cloud Firestore** (collections, documents, queries, real-time updates)
- Using **Realtime Database** for real-time data synchronization
- Managing **file uploads/downloads** with Cloud Storage
- Calling **Cloud Functions** from Angular
- Implementing **analytics**, **performance monitoring**, or **remote config**
- Setting up **push notifications** with Cloud Messaging
- Protecting routes with **auth guards**
- Configuring **Firebase emulators** for local development
- Building **server-side rendered** Angular apps with Firebase

Do NOT use this skill when:

- Using Firebase JS SDK directly without Angular wrappers
- Working with non-Firebase backends
- The Firebase product you need is not supported by AngularFire
