What is Firebase?

Firebase is the Backend-as-a-Service (BaaS) platform which is developed by Google and provides a variety of tools and services for building web and mobile applications. It simplifies the backend development tasks like database management, authentication, file storage, and real-time data syncing. Allows the developers to focus on building high-quality applications. The Firebase integrates well with other Google Cloud products and offers cross-platform support.

How To Use Firebase?

Step 1: Create the Firebase Project

Go to Firebase Console. Click on the Get Started with a Firebase project to create a new project. Enter a project name and follow the prompts to enable Google Analytics (optional).

Step 2: Set Up the Firebase SDK

Once project is created, click on platform you're developing (e.g., Web, iOS, Android).Follow instructions to addn the Firebase SDK to your app. For the web projects, add Firebase scripts in your HTML file.

<script src="https://www.gstatic.com/firebasejs/8.0.0/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.0.0/firebase-firestore.js"></script>

Step 3: Initialize the Firebase in Your App

Add the Firebase configuration in to your project.

var firebaseConfig = {
    apiKey: "YOUR_API_KEY",
    authDomain: "YOUR_PROJECT_ID.firebaseapp.com",
    projectId: "YOUR_PROJECT_ID",
    storageBucket: "YOUR_PROJECT_ID.appspot.com",
    messagingSenderId: "YOUR_SENDER_ID",
    appId: "YOUR_APP_ID"
};
firebase.initializeApp(firebaseConfig);

Step 4: Integrating the Firebase Services

You can now integrate the services such as Firebase Authentication, Firestore Database, or the Cloud Functions into your app.
For instance adding the Firestore:

var db = firebase.firestore();
db.collection("users").add({
    name: "Raj Kumar",
    email: "[email protected]"
})
.then(function(docRef) {
    console.log("Document written with ID: ", docRef.id);
})
.catch(function(error) {
    console.error("Error adding document: ", error);
});

Example: This example Demonstrates the usage of Firebase Authentication and Firestore.

                firebase.initializeApp(firebaseConfig);

                // Firestore
                var db = firebase.firestore();
                db.collection("users").add({

                    console.log("Document added: ", docRef.id);
        });

                // Firebase Authentication
                firebase.auth()
                .signInWithEmailAndPassword("[email protected]", "password123")
            .then(user => {

Why We Choose it?

The Firebase is designed as a severless platform which means that the developers do not need to manage or scale servers manually. The core components of Firebase are built on the Google Cloud, ensuring reliability and high availability.

Key elements of Firebase architecture include:

Backend-as-a-Service(BaaS): The firebase abstracts back-end complexities and it allows the developers to use the APIs to interact with services.
Event-driven architecture: Firebase uses the triggers(events) to invoke cloud functions or the other services automatically.
Data synchronization: Firebase keeps all the connected clients updated in real-time, making it ideal for the interactive apps.

Key Features of the Firebase

Real-time database:The firebase is real-time NoSQL database allows the developers to store and sync the data across all clients in real-time.
Cloud Firestore: Firestore is the Firebase's scalable NoSQL cloud database that offers an automatic scaling, high performance, and the real-time capabilities.
Firebase Authentication:Firebase Authentication helps the developers to implement secure authentication mechanisms using by various identity provider such as Google, Facebook, Twitter, GitHub and emial/password.
Cloud Functions:Cloud Functions allows the developer to write server-sides code that automatically runs in response to the events triggered by Firebase features and the HTTPs requests.
Firebase Cloud Messaging(FCM): Firebase Cloud Messaging provides the way to send notifications to users across the platforms(iOS,Android and the web).
Firebase Hosting: Firebase Hosting offer the fast, secure and reliable hosting for a static and dynamic content. It is optimized for the web and mobile app hosting, providing SSL certificates by the default for security.

Advantages of Firebase

Simplified App Development: Firebase abstracts much of the complexity that associted with backend services such as authentication, database and the cloud functions which allow developers to focus on creating front-end and the business logic of apps.
Real-time Data Synchronization: With the real-time database and the Firestore, Firebase make it easier to build the apps that require live updates.
Cross-Platform Support: Firebase offer the strong support for cross-platform apps that includes Android, iOS and Web. The unified API across all platforms ensures that the developers do not have to write seperate codebases for each the platform when using Firebase Services.
Security: The Firebase provides built-in security rules and the policies to protect all data accesses and prevent the unauthorized usage.
Scalabilty: The Firebase automatically scales with our app's growth. Whether we have the small user base or millions of users. Firebase can handle the load without manual intervention.

Use Cases of Firebase

Social Media and Chat Apps: Firebase is the real-time database which is perfectly suited for building the chat apps where messages need to be delivered instantaneously across all the users.
Collaborative Platforms: Applications that allow for multiple users to collaborative in the real-time, such as document editing tools or the project management apps that benefit from Firebase's data synchronization capabilities.
E-commerce Apps: Firebase Authentication and the Cloud Firestore are frequently used in the e-commerce apps for managing the user accounts, product catalogs and the orders.
Game Development: The Firebase's cloud functions, real-time analytics and the performance monitoring make it the popular coice for game developes looking to manage the back-end infrastructure while optimizing the user experience.
