Write a specification for the git commit hook script

[DavidKalina]

Overview

This script integrates with Git's pre-commit and post-commit hooks to capture and transmit commit information to a remote server for analysis. It requires a Node.js environment and TypeScript for development.

Requirements

Node.js: Latest LTS version highly recommended. TypeScript: A recent version that aligns with your Node.js installation. Git: Version 2.x or higher.

Functionality

1. Pre-commit Hook Integration: Intercepts commit attempts and can optionally run checks or preprocessing tasks before the commit proceeds.

2. Post-commit Hook Integration: Gathers commit data: commit message, author details, diff output. Transmits data to the designated server endpoint.

3. Data Handling: Structures captured data (likely as JSON). Secure HTTPS transmission with error handling.

Inputs

• Commit Data: Message, author information, hash, timestamp, and change diff.
• Configuration: Server URL, any authentication needed.

Outputs

Success/Failure Acknowledgement: Console output on transmission status. Error Messages: Detailed logs for troubleshooting (network issues, server-side problems, etc.).

Error Handling

Graceful error handling and logging, preventing interruptions to the Git workflow (unless explicitly desired). Configurable retries for network/server errors, with either silent failure or user notification after exceeding the retry limit.

Configuration

• .env file or a package.json section is recommended for:
• Server endpoint URL
• Authentication details
• Retry count for transmissions

Security Considerations

• HTTPS only for transmission.
• Secure handling of sensitive data (auth tokens, etc.).
• Input sanitization to mitigate injection risks on the server side.

Development Steps

• TypeScript Project Setup: Initialize with appropriate tsconfig settings.
• Script Development: Write TypeScript code handling hooks, data capture, and secure transmission logic.
• Testing: Thorough manual and automated test cases to verify behavior in various commit scenarios.
• Deployment: Document the hook integration process for development environments.

Future Enhancements

• Granular configuration for selecting specific commit data to send.
• More robust error reporting and logging systems.
