Introduction

Using JavaScript to manage files in a storage bucket is an efficient way to programmatically upload and delete files. This guide provides detailed steps for configuring a Node.js environment and using JavaScript to securely manage files in your storage bucket with SSL. This guide demonstrates the setup process using Node.js version 18, covering both Debian-based and Red Hat-based distributions. After setting up Node.js, follow the steps to download, configure, and run sample code for file management tasks.

Prerequisites

• Node.js version 18 installed on your environment.
• Access credentials for your storage bucket, including access key, secret key, endpoint, and region.
• Basic knowledge of command-line interface and text editor usage.

Step-by-Step Guide

Step 1: Install Node.js (Version 18)

For Debian-based Distributions

Update the system and install the necessary components:

sudo apt-get update && sudo apt-get install -y ca-certificates curl gnupg

Add NodeSource’s GPG key and repository:

sudo apt-get update && sudo apt-get install -y ca-certificates curl gnupg
curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg
NODE_MAJOR=18
echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_$NODE_MAJOR.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list
sudo apt-get update && sudo apt-get install nodejs -y

For Red Hat-based Distributions

Use the following command:

sudo dnf module install nodejs:18

Step 2: Download Sample Code and Install Dependencies

Download the sample code provided for uploading and deleting files in a bucket:

wget https://www.ipserverone.info/wp-content/uploads/2023/10/javascript.tar.gz
tar -xf javascript.tar.gz
cd javascript
npm install

Step 3: Configure Access Credentials and Endpoint

To manage files, configure the access credentials and endpoint information. Open client.js in a text editor:

vim client.js

Edit the following lines to include your access key, secret key, endpoint, and region information:

accessKeyId: 'ACCESS_KEY',
secretAccessKey: 'SECRET_KEY',
endpoint: 'https://ap-southeast-mys1.oss.ips1cloud.com',
region: 'ap-southeast-mys1'

Configure your endpoint and region accordingly:

endpoint: 'https://ap-southeast-mys1.oss.ips1cloud.com',
region: 'ap-southeast-mys1'

Step 4: Set Up package.json

Open package.json to specify the main module to run:

vim package.json

To upload files, set the main field to “uploadFile.js” :

"main": "uploadFile.js"

For deleting files, set the main field to “deleteFile.js” :

"main": "deleteFile.js"

Uploading Files

Step 1: Prepare Files for Upload

Create a directory for the assets you wish to upload and a sample file:

mkdir assets
echo "Hello world" > assets/sample_upload.txt

Step 2: Configure uploadFile.js

Open uploadFile.js in a text editor:

vim uploadFile.js

Update the following lines to specify the bucket name, file path, and file name in the bucket:

Bucket: 'sample-bucket-01',
Key: 'uploaded_text.txt',
Body: readFileSync('./assets/sample_upload.txt')

Step 3: Run the Upload Script

Ensure that  package.json is set to run uploadFile.js and execute the upload command:

node uploadFile.js

If the upload is successful, you will receive an HTTP 200 status code, indicating that the file has been uploaded to the bucket.

Deleting Files

Step 1: Configure deleteFile.js

Open deleteFile.js in a text editor:

vim deleteFile.js

Edit the following lines to specify the bucket name and the file you want to delete:

Bucket: 'sample-bucket-01',
Key: 'uploaded_text.txt'

Step 2: Run the Delete Script

Ensure that package.json is set to run deleteFile.js and execute the delete command:

node deleteFile.js

If the deletion is successful, you will receive an HTTP 204 status code, confirming that the file has been removed from the bucket.
