Go Cloud Storage API

The cloudbucket package provides functionality to interact with a cloud storage bucket using the Google Cloud Storage service.

Features

• File Upload: Upload a file to the cloud storage bucket.
• File Retrieval: Retrieve a file from the cloud storage bucket.
• Object Listing: List all objects in the cloud storage bucket.
• Signed URL Generation: Generate a signed URL for accessing a file in the cloud storage bucket.
• Bulk Object Retrieval: Retrieve and store all objects from the cloud storage bucket.
• Object Deletion: Delete an object from the cloud storage bucket.
• Update Object: Update an existing object in the cloud storage bucket.

Prerequisites

Before using the cloudbucket package, make sure you have completed the following steps:

1. Google Cloud Storage Account: Sign up for a Google Cloud Storage account and create a bucket.

2. Service Account Key:

   • Go to the Google Cloud Console.
   • On the burger menu on top left select APIs & Services -> Credentials. That opens the page in the background. Click CREATE CREDENTIALS and select Service Account.
   • After clicking CREATE, you should be redirected to Create Role section. Search Cloud Storage and Storage Admin. Click on CONTINUE. You should be redirected to another page. Click DONE.
   • It creates you Service Account. Click on the account and you’ll be redirected to next page.
   • On Keys section. Click Add Key” -> Create new key.
   • In the Create key step, select JSON as the key type and click on Create. This will download the service account key file (keys.json).
   • Store the keys.json file securely. It will be used for authentication when accessing the cloud storage bucket.

3. Set up Authentication:

   • Ensure that you have the keys.json file generated in the previous step.
   • Place the keys.json file in a secure location within your project directory.
   • Provide the path to the keys.json file when initializing the storageClient in your code:

By following these steps, you will have a Google Cloud Storage account, a service account key (keys.json), and the necessary authentication set up for using the cloudbucket package.
