Integrating Firebase SDK with Node.js

Firebase is a platform developed by Google for creating web and mobile applications. It offers various services such as a real-time database, authentication, cloud storage, and more. In this tutorial, we’ll explore how to integrate Firebase SDK with a Node.js application, focusing on Firestore as our database.

Prerequisites

Before we begin, ensure you have the following:

• Node.js installed on your machine
• A Firebase project created on the Firebase console (https://console.firebase.google.com/)
• Basic knowledge of JavaScript and Node.js

Setting up Firebase

1. Go to the Firebase console and create a new project.
2. Once the project is created, click on “Add Firebase to your web app” to get your Firebase configuration object.

Installing Firebase SDK

1. Open your terminal and navigate to your Node.js project directory.
2. Install the Firebase SDK using npm:

npm install firebase

Initializing Firebase in your Node.js application

1. Create a new JavaScript file (e.g., app.js) in your project directory.
2. Import the Firebase SDK and initialize it with your Firebase configuration:

Using Firebase Firestore

In this example, we’ll demonstrate basic operations with Firebase Firestore, such as reading, writing, updating, and deleting data.

Writing Data to Firestore

Reading Data from Firestore

Updating Data in Firestore

Deleting Data from Firestore

Conclusion

In this tutorial, we’ve learned how to integrate Firebase SDK with a Node.js application and perform basic operations using Firebase Firestore. Firebase offers many more features such as authentication, cloud storage, and real-time database, which you can explore further in the official Firebase documentation.
