GitHub Workflow Version Control Dashboard with Commit History and Rollbacks

This n8n workflow provides a comprehensive solution for monitoring and managing GitHub repository changes. It acts as a central hub for tracking commit history, identifying potential rollbacks, and visualizing key development metrics.

What it does

This workflow is designed to be a robust system for various GitHub-related automation tasks. While the provided JSON is a barebones structure, it outlines the foundational components for a powerful version control dashboard.

1. Triggers on various events: The workflow is equipped to be triggered by a Webhook (for external events) or a Schedule Trigger (for periodic checks). It also includes an Execute Workflow Trigger, indicating it can be part of a larger, modular n8n setup.
2. Interacts with GitHub: It includes a GitHub node, suggesting it can fetch repository data, commit details, or other relevant information from GitHub.
3. Processes and Transforms Data: The workflow utilizes several core n8n nodes for data manipulation:
   • HTTP Request: For making custom API calls, potentially to other services or GitHub endpoints not directly covered by the GitHub node.
   • If and Switch: For implementing conditional logic and branching the workflow based on data.
   • Merge and Aggregate: For combining and summarizing data from different paths or items.
   • Loop Over Items (Split in Batches): For iterating through lists of data, such as commits or pull requests.
   • Edit Fields (Set): For adding, modifying, or removing fields in the data.
   • Code: For executing custom JavaScript logic, allowing for highly flexible data processing.
   • Compare Datasets: For identifying differences between two sets of data, crucial for detecting changes or potential rollbacks.
   • Filter and Sort: For refining and ordering data.
   • Split Out: For deconstructing nested data structures.
   • HTML: Potentially for parsing HTML content, perhaps from GitHub commit messages or pull request descriptions.
   • Summarize: For generating summaries or aggregated statistics from the processed data.
4. Responds to Webhooks: The Respond to Webhook node indicates that this workflow can send custom responses back to the system that triggered it via a webhook, making it suitable for interactive or real-time integrations.
5. Modular Design: The Execute Sub-workflow and n8n nodes suggest that this workflow is designed to either call other n8n workflows or be called by them, promoting modularity and reusability.
6. No Operation (NoOp): The No Operation, do nothing node serves as a placeholder or a way to temporarily disable a branch of the workflow without breaking connections.

Prerequisites/Requirements

• n8n Instance: A running n8n instance to host and execute the workflow.
• GitHub Account: A GitHub account with appropriate access to the repositories you wish to monitor.
• GitHub Credentials: An n8n credential configured for GitHub (e.g., OAuth, Personal Access Token).
• Webhook Source (Optional): If using the Webhook trigger, an external service configured to send webhook events to your n8n instance.

Setup/Usage

1. Import the workflow: Download the provided JSON and import it into your n8n instance.
2. Configure GitHub Credentials:
   • Locate the "GitHub" node.
   • Click on the "Credential" field and select an existing GitHub credential or create a new one. Follow the n8n documentation for GitHub credentials if needed.
3. Configure Triggers:
   • Webhook: If you intend to trigger this workflow via a webhook, activate the "Webhook" node and copy its URL. Configure your external service (e.g., GitHub webhooks for repository events) to send POST requests to this URL.
   • Schedule Trigger: If you want the workflow to run at specific intervals, configure the "Schedule Trigger" node with your desired frequency (e.g., every hour, daily).
   • Execute Workflow Trigger: If this workflow is a sub-workflow, ensure the parent workflow is configured to call it correctly.
4. Customize Workflow Logic:
   • Review the HTTP Request, If, Switch, Code, Filter, and other data manipulation nodes. Adjust their settings, expressions, and conditions to match your specific requirements for monitoring, analyzing, and reacting to GitHub data.
   • For example, you might configure the GitHub node to list commits for a specific repository, then use an If node to check for certain commit messages or authors, and finally use an HTTP Request to send a notification to Slack or another service.
5. Activate the Workflow: Once configured, activate the workflow in n8n.
