NPM Google Cloud Storage

The npm package for Google Cloud Storage is a client library that allows Node.js developers to interact with Google Cloud Storage, a scalable and secure object storage service for storing and accessing data on Google Cloud Platform. This package makes it easier to perform various operations like uploading files, downloading files, managing buckets, and handling file metadata within a Node.js application.

Key Features

File Uploads and Downloads:
- Easily upload files to Google Cloud Storage or download files from it.
Bucket Management:
- Create, configure, and manage storage buckets.
Streamlined Data Operations:
- Stream data to and from your Cloud Storage objects.
Access Controls:
- Manage permissions and access controls for individual files and buckets.
File and Bucket Metadata:
- Retrieve and modify metadata for stored files and buckets.

Installation

To use Google Cloud Storage in your Node.js application, first, you need to install the package using npm:

bash

npm install @google-cloud/storage

Usage Example

Here’s a basic example of how to use the Google Cloud Storage npm package in a Node.js application:

javascript

const { Storage } = require('@google-cloud/storage');

// Creates a client using default credentials
const storage = new Storage();

async function listBuckets() {
  try {
    const [buckets] = await storage.getBuckets();
    console.log('Buckets:');
    buckets.forEach(bucket => {
      console.log(bucket.name);
    });
  } catch (err) {
    console.error('ERROR:', err);
  }
}

listBuckets();

This example lists all the storage buckets available in the associated Google Cloud project.

Authentication

To authenticate your application with Google Cloud, you’ll typically use a service account key. After creating a service account in the Google Cloud Console, you can download a JSON key file. Then, you can set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of the JSON key file:

bash

export GOOGLE_APPLICATION_CREDENTIALS="/path/to/your/keyfile.json"

Alternatively, if you are running your application on Google Cloud infrastructure (e.g., Compute Engine, App Engine), your application can use the default service account associated with the instance.
