Install @angular/fire


Quick Installation Steps

1. Grab your Firebase Web Config

From your Firebase project click the gear icon next to “Project Overview” to bring you to your project settings. On the general tab, in the *Your apps" section, click the </> button. This opens a popup called Add Firebase to your web app. You only need to copy the config object from this page.

It is perfectly OK to expose these credentials in your client-side code. Yes, somebody could use these credentials to write to your database, but Firebase apps are secured by writing [rules](/snippets/firestore-rules-recipes/).

2. Install @angular/fire via NPM

Install @angular/fire and firebase as dependencies in your Angular Project.

command line
npm install firebase @angular/fire

3. Add @angular/fire to the App Module

At this point, we can import the Firebase modules we need into Angular. The only required module is AngularFireModule. All other modules can be removed or added based on your needs. You

file_type_ng_component_ts src/app/app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

// 1. Import the libs you need
import { AngularFireModule } from '@angular/fire';
import { AngularFirestoreModule } from '@angular/fire/firestore';
import { AngularFireStorageModule } from '@angular/fire/storage';
import { AngularFireAuthModule } from '@angular/fire/auth';

// 2. Add your credentials from step 1
const config = {
    apiKey: '<your-key>',
    authDomain: '<your-project-authdomain>',
    databaseURL: '<your-database-URL>',
    projectId: '<your-project-id>',
    storageBucket: '<your-storage-bucket>',
    messagingSenderId: '<your-messaging-sender-id>'

  imports: [
    // 3. Initialize
    AngularFirestoreModule, // firestore
    AngularFireAuthModule, // auth
    AngularFireStorageModule // storage
  declarations: [ AppComponent ],
  bootstrap: [ AppComponent ]
export class AppModule {}

4. Usage in a Component

Done! Now you can use any of these modules in your components or services. For example, let’s listen to a Firestore database collection in realtime.

file_type_ng_component_ts src/app/app.component.ts
import { AngularFirestore } from '@angular/fire/firestore';

export class SomeComponent {

  constructor(private db: AngularFirestore) {
      const things = db.collection('things').valueChanges();

Pro Tip: Dev and Prod Firebase Projects

It can be beneficial to setup two Firebase projects - one for development and another for your live production app. In Angular, we can manage these projects easily with the built-in environment config.

file_type_ng_component_ts environment.ts
export const environment = {
  production: false,
  firebase: {
      // your web config from step 1

// In other files, import the environment like so:
import { environment } from '../environments/environment';
