Install angularfire2 the official Angular library for Firebase.

npm install firebase @angular/fire --save

Firebase config

From the Firebase Console go to Settings then in the General tab click on Add Firebase to your web app

Copy only the code in the config, create a new file src/environments/firebase.ts

export const firebaseConfig = {
  apiKey: 'your-value',
  authDomain: 'your-value',
  databaseURL: 'your-value',
  projectId: 'your-value',
  storageBucket: 'your-value',
  messagingSenderId: 'your-value'

Add the file to .gitignore

# Secret files

Open src/environments/environment.ts

import { firebaseConfig } from './firebase';

export const environment = {
  production: false,
  firebase: firebaseConfig

Similar in src/environments/

import { firebaseConfig } from './firebase';

export const environment = {
  production: true,
  firebase: firebaseConfig


Open src/app/app.module.ts and add AngularFireModule in the imports

import { AngularFireModule } from '@angular/fire';
import { environment } from '../environments/environment';
  imports: [

Setup individual modules

Add modules for the individual @NgModules, the full list is

  • AngularFireAuthModule
  • AngularFireDatabaseModule
  • AngularFireFunctionsModule
  • AngularFirestoreModule
  • AngularFireStorageModule
  • AngularFireMessagingModule

In JobSearchLog we will use Auth, Firestore and Storage. The complete app.module.ts is

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AngularFireModule } from '@angular/fire';
import { AngularFirestoreModule } from '@angular/fire/firestore';
import { AngularFireStorageModule } from '@angular/fire/storage';
import { AngularFireAuthModule } from '@angular/fire/auth';

import { AppComponent } from './app.component';
import { environment } from '../environments/environment';

  declarations: [
  imports: [
  providers: [],
  bootstrap: [AppComponent]
export class AppModule { }

Test Firestore

Open app.component.ts and add a DI for AngularFirestore, bind a Firestore collection to a list

import { Component } from '@angular/core';
import { AngularFirestore } from '@angular/fire/firestore';
import { Observable } from 'rxjs';

  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
export class AppComponent {
  title = 'JobSearchLog';
  items: Observable<any[]>;

  constructor(db: AngularFirestore) {
    this.items = db.collection('items').valueChanges();

Change the template to visualize the items

<div style="text-align:center">
    Welcome to {{ title }}!

  <li *ngFor="let item of items | async">

Run the application

ng serve

Open the browser at the address http://localhost:4200/ and verify that there is no content in the list.

Create Cloud Firestore database

Open the Firebase Console, go to Database and click Create Database in the Firestore section.

Create the database in test mode (we will configure permission later)

Add a new collection with Collection ID items.

On the add first document step leave Auto-ID and add a Field name with a value of test.

In the browser there is new list item.

Add some new document in the collection and verify that they appear in the application.
