Upload Images / Files to Firebase Cloud Storage using Node JS

Firebase Cloud Storage is a powerful solution for storing and retrieving user-generated content like images, videos, and documents. In this article, we will learn how to upload images or files to Firebase Cloud Storage using Node JS.

Step 1: Set up Firebase Project

The first step is to create a new project in the Firebase Console and set up Firebase in your Node JS project. You can follow the official Firebase documentation to create and set up a new project.

Step 2: Install Firebase Storage SDK

Next, you need to install the Firebase Storage SDK for Node JS. You can do this by running the following command in your Node JS project directory:

npm install @google-cloud/storage

Step 3: Initialize Firebase Storage

After installing the Firebase Storage SDK, you need to initialize Firebase Storage in your Node JS project. You can do this by creating a new instance of the Storage class and passing your Firebase project’s credentials.

const { Storage } = require('@google-cloud/storage');
const storage = new Storage({
  keyFilename: 'path/to/your/firebase-project-credentials.json',
});

Step 4: Upload Images / Files to Firebase Cloud Storage

Now that Firebase Storage is initialized, you can upload images or files to Firebase Cloud Storage using the following code:

async function uploadFileToStorage(filePath, destinationPath) {
  const bucket = storage.bucket('your-firebase-storage-bucket');
  await bucket.upload(filePath, {
      destination: destinationPath,
  });
  console.log('File uploaded to Firebase Cloud Storage');
}

// Example usage
const filePath = 'path/to/your/local/file.jpg';
const destinationPath = 'images/file.jpg';
uploadFileToStorage(filePath, destinationPath);

Step 5: Handle Upload Errors

It’s important to handle errors that may occur during the file upload process. You can use try/catch blocks to handle any errors that may occur during the upload process.

try {
  // Upload file to Firebase Cloud Storage
  uploadFileToStorage(filePath, destinationPath);
} catch (error) {
  console.error('Error uploading file to Firebase Cloud Storage:', error);
}
