AngularFire

The official Angular library for Firebase.

ng add @angular/fire

Note: If you want to ng add AngularFire and will be using Hosting/Cloud Functions, you need to configure the Firebase CLI first so that you are logged in for the schematics that are run as part of ng add @angular/fire. Follow this guide to have the Firebase CLI walk you through the setup.

AngularFire smooths over the rough edges an Angular developer might encounter when implementing the framework-agnostic Firebase JS SDK & aims to provide a more natural developer experience by conforming to Angular conventions.

• Dependency injection - Provide and Inject Firebase services in your components
• Zone.js wrappers - Stable zones allow proper functionality of service workers, forms, SSR, and pre-rendering
• Observable based - Utilize RxJS rather than callbacks for realtime streams
• NgRx friendly API - Integrate with NgRx using AngularFire's action based APIs.
• Lazy-loading - AngularFire dynamically imports much of Firebase, reducing time to load your app
• Deploy schematics - Get your Angular application deployed on Firebase Hosting with a single command
• Google Analytics - Zero-effort Angular Router awareness in Google Analytics
• Router Guards - Guard your Angular routes with built-in Firebase Authentication checks

Example use

import { provideFirebaseApp, getApp, initializeApp } from '@angular/fire/app';
import { getFirestore, provideFirestore } from '@angular/fire/firestore';

@NgModule({
  imports: [
    provideFirebaseApp(() => initializeApp({ ... })),
    provideFirestore(() => getFirestore()),
  ],
  ...
})
export class AppModule { }

import { inject } from '@angular/core';
import { Firestore, collectionData, collection } from '@angular/fire/firestore';
import { Observable } from 'rxjs';

interface Item {
  name: string,
  ...
};

@Component({
  selector: 'app-root',
  template: `
  <ul>
    <li *ngFor="let item of item$ | async">
      {{ item.name }}
    </li>
  </ul>
  `
})
export class AppComponent {
  item$: Observable<Item[]>;
  firestore: Firestore = inject(Firestore);

  constructor() {
    const itemCollection = collection(this.firestore, 'items');
    this.item$ = collectionData(itemCollection);
  }
}

Compatibility

Angular and Firebase versions

AngularFire doesn't follow Angular's versioning as Firebase also has breaking changes throughout the year. Instead we try to maintain compatibility with both Firebase and Angular majors for as long as possible, only breaking when we need to support a new major of one or the other.

Angular	Firebase	AngularFire
16	9	^7.6
15	9	^7.5
14	9	^7.4
13	9	^7.2
12	9	^7.0
12	7,8	^6.1.5
11	7,8	^6.1
10	8	^6.0.4
10	7	^6.0.3
9	8	^6.0.4
9	7	^6.0

_{Version combinations not documented here may work but are untested and you will see NPM peer warnings.}

Polyfills

Neither AngularFire or Firebase ship with polyfills. To have compatibility across as wide-range of environments we suggest the following polyfills be added to your application:

API	Environments	Suggested Polyfill	License
Various ES5+ features	Safari < 10	core-js/stable	MIT
globalThis	Chrome < 71 Safari < 12.1 iOS < 12.2 Node < 12	globalThis	MIT
Proxy	Safari < 10	proxy-polyfill	Apache 2.0
fetch	Safari < 10.1 iOS < 10.3	cross-fetch	MIT

Resources

Quickstart - Get your first application up and running by following our quickstart guide.

Contributing

Stackblitz Template - Remember to set your Firebase configuration in app/app.module.ts.

Sample apps

We have three sample apps in this repository:

1. samples/compat a kitchen sink application that demonstrates use of the "compatibility" API
2. samples/modular a kitchen sink application that demonstrates the new tree-shakable API
3. samples/advanced the same app as samples/modular but demonstrates more advanced concepts such as Angular Universal state-transfer, dynamically importing Firebase feature modules, and Firestore data bundling.

Having troubles?

Get help on our Q&A board, the official Firebase Mailing List, the Firebase Community Slack (#angularfire2), the Angular Community Discord (#firebase), Gitter, the Firebase subreddit, or Stack Overflow.

NOTE: AngularFire is maintained by Googlers but is not a supported Firebase product. Questions on the mailing list and issues filed here are answered on a best-effort basis by maintainers and other community members. If you are able to reproduce a problem with Firebase outside of AngularFire's implementation, please file an issue on the Firebase JS SDK or reach out to the personalized Firebase support channel.

Developer Guide

This developer guide assimes you're using the new tree-shakable AngularFire API, if you're looking for the compatability API you can find the documentation here.

See the v7 upgrade guide for more information on this change..
