Overview

Angular_Fire combines the power of Angular with the flexibility of Firebase. This project allows developers to create dynamic, real-time applications with minimal effort. With Angular’s robust framework and Firebase’s backend services, you can focus on building features without worrying about server management.

Features

• Real-time Data: Synchronize data across all clients in real-time.
• Offline Support: Users can access data even without an internet connection.
• Notifications: Easily implement push notifications to engage users.
• State Management: Use NgRx for effective state management in your applications.
• Cloud Functions: Run backend code in response to events triggered by Firebase features.
• Firestore Integration: Store and sync data with Cloud Firestore, a NoSQL database.
• User Authentication: Secure your application with Firebase Authentication.

Technologies Used

• Angular: A platform for building mobile and desktop web applications.
• Firebase: A platform developed by Google for creating mobile and web applications.
• AngularFire: The official library for Firebase and Angular integration.
• Cloud Firestore: A flexible, scalable database for mobile, web, and server development.
• Cloud Functions: Event-driven serverless compute platform.
• NgRx: Reactive state management for Angular applications.
• RxJS: A library for reactive programming using Observables.

Installation

To get started with Angular_Fire, follow these steps:

1. Clone the Repository:

   git clone https://github.com/jayant-cell/Angular_Fire.git
   

2. Navigate to the Project Directory:

   cd Angular_Fire
   

3. Install Dependencies:

   npm install
   

4. Set Up Firebase:
   • Create a Firebase project in the Firebase Console.
   • Add your web app and copy the Firebase configuration.
5. Configure Firebase in Your Project:
   • Open src/environments/environment.ts and add your Firebase config:

     export const environment = {
     production: false,
     firebase: {
       apiKey: "YOUR_API_KEY",
       authDomain: "YOUR_AUTH_DOMAIN",
       projectId: "YOUR_PROJECT_ID",
       storageBucket: "YOUR_STORAGE_BUCKET",
       messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
       appId: "YOUR_APP_ID"
     }
     };
     

6. Run the Application:

   ng serve
   

7. Access the App: Open your browser and go to http://localhost:4200.

Usage

After setting up the project, you can start building your application. Here are some examples of how to use the features:

Real-time Data

To fetch real-time data from Firestore:

import { AngularFirestore } from '@angular/fire/firestore';

constructor(private firestore: AngularFirestore) {}

getItems() {
  return this.firestore.collection('items').valueChanges();
}

Offline Support

To enable offline data persistence:

import { AngularFirestore } from '@angular/fire/firestore';

constructor(private firestore: AngularFirestore) {
  this.firestore.firestore.enablePersistence()
    .catch((err) => {
      console.error('Persistence failed', err);
    });
}

Notifications

Set up push notifications using Firebase Cloud Messaging:

import { AngularFireMessaging } from '@angular/fire/messaging';

constructor(private afMessaging: AngularFireMessaging) {
  this.afMessaging.requestToken.subscribe(
    (token) => {
      console.log('Permission granted! Save to the server!', token);
    },
    (error) => {
      console.error('Unable to get permission to notify.', error);
    }
  );
}

State Management with NgRx

Set up NgRx to manage your application’s state effectively:

import { Store } from '@ngrx/store';
import { Observable } from 'rxjs';

export class AppComponent {
  items$: Observable<Item[]>;

  constructor(private store: Store<{ items: Item[] }>) {
    this.items$ = store.select('items');
  }

  loadItems() {
    this.store.dispatch(loadItems());
  }
}
