No Firebase App ‘[DEFAULT]’: How to Import Firebase 10.3.1 in module.ts File in Ionic Angular Project

If you are working on an Ionic Angular project and trying to import Firebase 10.3.1 in your module.ts file, you may encounter the error message “No Firebase App ‘[DEFAULT]’”. This error occurs when the Firebase app is not properly initialized or imported in your project. In this blog post, we will explore two possible solutions to resolve this issue.

Solution 1: Import Firebase and Initialize the App

The first solution involves importing Firebase and initializing the app in your module.ts file. Follow the steps below:

1. Install Firebase using npm:

    npm install firebase@10.3.1 --save
  

2. Import Firebase and initialize the app in your module.ts file:

    import * as firebase from 'firebase/app';
    import 'firebase/auth';
    import 'firebase/firestore';
    
    const firebaseConfig = {
      // Your Firebase configuration
    };
    
    firebase.initializeApp(firebaseConfig);
  

Make sure to replace firebaseConfig with your actual Firebase configuration.

Solution 2: Use AngularFire Module

The second solution involves using the AngularFire module, which provides a simplified way to work with Firebase in Angular projects. Follow the steps below:

1. Install AngularFire using npm:

    npm install @angular/fire@5.4.2 firebase@10.3.1 --save
  

2. Import the AngularFire module and initialize the app in your module.ts file:

    import { AngularFireModule } from '@angular/fire';
    import { AngularFireAuthModule } from '@angular/fire/auth';
    import { AngularFirestoreModule } from '@angular/fire/firestore';
    
    const firebaseConfig = {
      // Your Firebase configuration
    };
    
    AngularFireModule.initializeApp(firebaseConfig),
    AngularFireAuthModule,
    AngularFirestoreModule
  

Again, make sure to replace firebaseConfig with your actual Firebase configuration.

By following either of these solutions, you should be able to import Firebase 10.3.1 in your module.ts file without encountering the “No Firebase App ‘[DEFAULT]’” error. Remember to replace the placeholder values with your actual Firebase configuration.

Happy coding!
