Angular 8 Firebase tutorial: Integrate Firebase into Angular 8 App with @angular/fire

angular-8-firebase-tutorial-integrate-angular-fire-feature-image

Firebase is a mobile and web application development platform developed by Google. We can build our apps very fast, without making complex back-end system. It helps to scale automatically, for even the largest apps. In this Angular 8 Firebase tutorial, we’re gonna integrate Firebase into Angular 8 App with @angular/fire module (official library for Firebase and Angular).

Integrate Firebase into Angular 8 App

Step 1: Set up the Firebase Project

Go to Firebase Console, login with your Google Account, then click on Add Project.

Enter Project name, set Project Id and select Country/Region:

Press CREATE PROJECT, browser turns into:

Click on Web App, a Popup will be shown:

Save the information for later usage.

Choose Database in the left (list of Firebase features) -> Realtime Database -> Tab RULES, then change .read and .write values to true:

Step 2: Install @angular/fire and firebase

Run command:
npm install firebase @angular/fire --save

Step 3: Add Firebase config to environments variable

Open /src/environments/environment.ts, add your Firebase configuration that we have saved when Popup window was shown:


export const environment = {
  production: false,
  firebase: {
    apiKey: 'xxx',
    authDomain: 'gkz-angular-firebase.firebaseapp.com',
    databaseURL: 'https://gkz-angular-firebase.firebaseio.com',
    projectId: 'gkz-angular-firebase',
    storageBucket: 'gkz-angular-firebase.appspot.com',
    messagingSenderId: '189575342164'
  }
};

Step 4: Setup @NgModule

Open /src/app/app.module.ts, import AngularFireModule and other @angular/fire modules if necessary (we use Firebase Database, for example).

Don’t forget to specify Firebase configuration with AngularFireModule.initializeApp(firebaseConfig):


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

import { AngularFireModule } from '@angular/fire';
import { AngularFireDatabaseModule } from '@angular/fire/database';
import { environment } from '../environments/environment';

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

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    AngularFireModule.initializeApp(environment.firebase),
    AngularFireDatabaseModule, // for database
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Step 5: Use @angular/fire module in Angular component

Open /src/app/app.component.ts:


import { Component } from '@angular/core';
import { AngularFireDatabase } from '@angular/fire/database';
import { Observable } from 'rxjs';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'Angular8Firebase';
  description = 'Angular-Fire-Demo';

  itemValue = '';
  items: Observable;

  constructor(public db: AngularFireDatabase) {
    this.items = db.list('items').valueChanges();
  }

  onSubmit() {
    this.db.list('items').push({ content: this.itemValue});
    this.itemValue = '';
  }
}

/src/app/app.component.html:

<div class="container-fluid">
  <div style="color: blue;">
    <h1>{{title}}</h1>
    <h3>{{description}}</h3>
  </div>

  <div style="width: 300px;">
    <form (ngSubmit)="onSubmit()">
      <div class="form-group">
        <label for="item">Item</label>
        <input type="text" class="form-control"
          placeholder="Enter content..." id="item"
          required [(ngModel)]="itemValue" name="item">
      </div>

      <div class="btn-group">
        <button type="submit" class="btn btn-success">Submit</button>
      </div>
    </form>
  </div>

  <h2>Content from Firebase</h2>
  <div class="col-md-3">
    <pre *ngFor="let item of items | async">{{item.content}}</.pre>
  </div>

</div>

Check Result

– Run Angular project with command: npm start or ng serve.
– Open browser with url http://localhost:4200/, enter Item content.
Item data displays immediately:

Firebase Console Database:

Conclusion

Now we have known how to create a Firebase Project, how to integrate that Firebase Project into Angular Application, we also look at the idea to use @angular/fire module to work with Firebase in simple way.

Happy learning! See you later.

  Hello,
  Did you get any errors because of these imports:
  import { AngularFireModule } from ‘@angular/fire’;

  import { environment } from ‘../environments/environment’;
  when placed in your code?
  Could you help me please?

    Why are you importing analytics, apps, and the rest?
