02. AngularFirebase2 Tutorial: Install and Set up Firebase Database in Angular Project.

To install the AngularFirebase 2 library in Angular project, you need to run the below command in your terminal.

npm install firebase @angular/fire --save

To make connection between your Firebase database and Angular app.

Go to src > environments folder and add your Firebase config details in both the environment files.

environment.prod.ts

export const environment = {
  production: true,
  firebase: {
    apiKey: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    authDomain: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    databaseURL: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    projectId: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    storageBucket: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    messagingSenderId: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
  }
};

environment.ts

export const environment = {
  production: false,
  firebase: {
    apiKey: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    authDomain: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    databaseURL: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    projectId: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    storageBucket: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    messagingSenderId: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
  }
};

It’s time to import Firebase services in app.module.ts file.

// Firebase services + environment module
import { AngularFireModule } from '@angular/fire/compat';
import { AngularFireAuthModule } from '@angular/fire/compat/auth';
import { AngularFireStorageModule } from '@angular/fire/compat/storage';
import { AngularFirestoreModule } from '@angular/fire/compat/firestore';
import { AngularFireDatabaseModule } from '@angular/fire/compat/database';
import { environment } from '../environments/environment';

@NgModule({
  imports: [
    AngularFireModule.initializeApp(environment.firebase),
    AngularFireAuthModule,
    AngularFirestoreModule,
    AngularFireStorageModule,
    AngularFireDatabaseModule,
  ]
})

So far, we have created the account in Firebase real-time NoSQL database.

Along with that, we have also set up the AngularFire2 library in Angular project.

Now you can use the powerful features of AngularFire2, and you can create your web and mobile app project.
