About This Tool

Primary Use Case

Key Features

• Command-line interface for easy URL processing
• Package interface for custom integration in Go projects
• Supports extraction of JavaScript sources from HTTP responses and web pages
• Handles multiple URLs via input files
• Options to autofill and resolve relative URLs
• Customizable HTTP request methods and headers
• Multi-threaded processing for faster extraction
• Verbose output for detailed runtime information

Insights & Recommendations

When using the tool, ensure the `--complete` option is used before `--resolve` to properly autofill and resolve relative URLs. The tool supports multi-threading to speed up processing but consider system resource limits when increasing threads. Custom HTTP headers and methods allow bypassing some access restrictions or mimicking specific clients.

Installation

Run `go install github.com/003random/getJS/v2@latest` to install the tool

Usage

Smart Usage Notes

• Integrate getJS in automated pentesting pipelines to quickly gather JS sources for vulnerability analysis.
• Combine with static analysis tools to detect insecure JavaScript code patterns early in development.
• Use multi-threaded extraction to scale reconnaissance across large target domains efficiently.
• Leverage verbose output for detailed debugging and to tailor custom scanning headers and methods.
• Incorporate getJS in purple team exercises to simulate attacker reconnaissance and improve defender detection capabilities.
