LambdaTest Screenshot Downloader & PDF Generator

A CLI tool that:

• Fetches session screenshots from LambdaTest
• Downloads the screenshots as a ZIP file
• Extracts the screenshots in order
• Generates a PDF from the extracted images

Features

• ✅ Fetch screenshots dynamically using a session ID
• ✅ Handles network issues and API failures gracefully
• ✅ Ensures correct order of screenshots in the final PDF
• ✅ Cleans up temporary files after execution
• ✅ Supports PNG, JPG, and JPEG images
• ✅ Allows specifying an output directory
• ✅ Secure authentication using AUTH_HEADER
• ✅ Generates uniquely named files per session (screenshots_<session_id>.pdf)

Installation

To install the CLI globally:

npm install -g lambdatest-screenshot-pdf

To use it locally:

git clone https://github.com/shubhamsinghrathore/lambdatest-screenshot-pdf.git
cd lambdatest-screenshot-pdf
npm install

Usage

Run the command with a valid LambdaTest session ID:

AUTH_HEADER="Basic your_encoded_auth_string" lambdatest-screenshot-pdf <session_id> --output <output_directory>

Example:

AUTH_HEADER="Basic cmF0aG9yZXNodWIyMjpPaTYxUDNxRXgybXprNKcXUyMmtZM1dCdFlXTm5LclZPeVRRQ01RRGdyNTZjVg==" lambdatest-screenshot-pdf 1a80510a-289a-46b7-9f60-da01d108de10 --output ~/Desktop/screenshots

What happens when you run the command?

1. Fetches the ZIP download URL for the session ID.
2. Downloads the ZIP file.
3. Extracts the screenshots into screenshots_<session_id>/.
4. Generates a uniquely named screenshots_<session_id>.pdf with all images in order.
5. Cleans up temporary files.

Output

After execution, you will get:

• screenshots_<session_id>.zip (Downloaded ZIP file)
• screenshots_<session_id>/ (Extracted images)
• screenshots_<session_id>.pdf (Final merged PDF file)

Error Handling

This tool handles:

• 🚨 Invalid session ID → Ensures a valid session is passed.
• 🚨 Missing AUTH_HEADER → Prevents execution without authentication.
• 🚨 Network issues → Handles API timeouts and retries.
• 🚨 Missing ZIP file → Gracefully exits if the file is unavailable.
• 🚨 Corrupt images → Skips bad images while generating the PDF.
• 🚨 Invalid output directory → Ensures the specified directory exists.

Dependencies

• axios - For making HTTP requests.
