Super Simple Batch Downloader

Super Simple Batch Downloader is a Node.js application that allows users to bulk download files from a specified URL location. The app handles:

• Encoding and decoding filenames to support special characters and spaces.
• Sequential downloads with a progress indicator and estimated time remaining.
• Fallback to PowerShell if Node.js encounters errors while downloading files.
• Interactive CLI mode for specifying download parameters dynamically.

Features

• Bulk file downloading via HTTP requests.
• Automatic filename encoding/decoding for proper URL handling.
• Interactive command-line input for flexible configuration.
• Progress tracking with file-specific percentage and time estimation.
• PowerShell fallback to ensure downloads succeed if Node.js requests fail.

Installation

Ensure you have Node.js installed, then clone the repository and install dependencies:

git clone https://github.com/YOUR-USERNAME/batch-http-downloader.git
cd batch-http-downloader
npm install

Dependencies:

npm install

Usage

1. Running via Command Line

Execute the script using:

node index.js

You will then be prompted to enter:

1. Base URL where the files are located.

2. Output directory for saving downloaded files.

3. File names (one per line, press Enter after each).

4. Type "DONE" to start downloading.

Example prompt:

Enter the base URL: https://example.com/files
Enter the output directory: ./downloads
Enter file names (press Enter after each, then type "DONE" to finish):
file1.txt
image.png
document.pdf
DONE

2. Using the downloadFiles function directly

You can integrate the function in another Node.js script:

const { downloadFiles } = require('./index.js');

const baseUrl = 'https://example.com/files';
const outputDir = './downloads';
const fileNames = ['file1.txt', 'image.png', 'document.pdf'];

downloadFiles(baseUrl, fileNames, outputDir);

3. PowerShell Fallback

If a download fails, the script automatically tries downloading via PowerShell (Windows only):

powershell -Command "& { $client = New-Object System.Net.WebClient; $client.DownloadFile('<file_url>', '<output_path>') }"

Enhancements & Future Improvements if you want to help and contribute

• Add support for multi-threaded downloads (parallel execution).
• Support authentication headers for restricted file access.
• Expand compatibility for Linux/Mac alternatives to PowerShell fallback.
