@angular/fire

What is @angular/fire?

@angular/fire is the official Angular library for Firebase. It provides a set of AngularFire modules that enable Angular applications to interact with Firebase services such as Firestore, Authentication, Storage, and more. This library simplifies the integration of Firebase with Angular applications, offering reactive and declarative APIs.

What are @angular/fire's main functionalities?

Firestore

This feature allows you to interact with Firestore, a NoSQL database provided by Firebase. The code sample demonstrates how to retrieve a collection of items from Firestore and subscribe to changes in real-time.

import { AngularFirestore } from '@angular/fire/compat/firestore';

constructor(private firestore: AngularFirestore) {}

getItems() {
  return this.firestore.collection('items').valueChanges();
}

Authentication

This feature enables authentication functionalities such as signing in, signing out, and managing user sessions. The code sample shows how to sign in a user using email and password.

import { AngularFireAuth } from '@angular/fire/compat/auth';

constructor(private afAuth: AngularFireAuth) {}

login(email: string, password: string) {
  return this.afAuth.signInWithEmailAndPassword(email, password);
}

Storage

This feature allows you to interact with Firebase Storage, which is used for storing and serving user-generated content such as images and videos. The code sample demonstrates how to upload a file to Firebase Storage.

import { AngularFireStorage } from '@angular/fire/compat/storage';

constructor(private storage: AngularFireStorage) {}

uploadFile(filePath: string, file: File) {
  const fileRef = this.storage.ref(filePath);
  return fileRef.put(file);
}

Realtime Database

This feature provides access to Firebase Realtime Database, a cloud-hosted NoSQL database that allows data to be stored and synchronized in real-time. The code sample shows how to retrieve a list of items from the Realtime Database.

import { AngularFireDatabase } from '@angular/fire/compat/database';

constructor(private db: AngularFireDatabase) {}

getItems() {
  return this.db.list('items').valueChanges();
}

Analytics

This feature enables the use of Firebase Analytics to log events and track user interactions within your application. The code sample demonstrates how to log a custom event.

import { AngularFireAnalytics } from '@angular/fire/compat/analytics';

constructor(private analytics: AngularFireAnalytics) {}

logEvent(eventName: string, eventParams: any) {
  this.analytics.logEvent(eventName, eventParams);
}

Other packages similar to @angular/fire

firebase

The 'firebase' package is the official Firebase JavaScript SDK. It provides comprehensive access to Firebase services but lacks the Angular-specific integrations and reactive APIs provided by @angular/fire. Developers using Angular would need to manually integrate Firebase services and manage state updates.

reactfire

The 'reactfire' package is the official Firebase library for React. It offers similar functionalities to @angular/fire but is tailored for React applications. It provides hooks and components to easily integrate Firebase services with React's component-based architecture.

vuefire

The 'vuefire' package is the official Firebase library for Vue.js. It provides bindings to integrate Firebase services with Vue.js applications, similar to how @angular/fire integrates with Angular. It offers Vue-specific features such as directives and plugins.
