n8n Workflow: Save Your Workflows into a GitHub Repository

This n8n workflow provides a robust framework for managing and saving your n8n workflows to a GitHub repository. While the provided JSON is a foundational structure, it outlines the essential components for a scheduled, conditional, and iterative process to interact with GitHub.

What it does

This workflow is designed to be a starting point for automating the backup or synchronization of n8n workflows to a GitHub repository. It demonstrates how to:

1. Trigger on a Schedule: The workflow can be initiated at predefined intervals using the Cron node.
2. Execute Custom Logic: A Function node allows for custom JavaScript code execution, which can be used for data manipulation, preparation, or conditional logic.
3. Interact with GitHub: The GitHub node enables actions like fetching repository contents, creating files, or updating existing ones.
4. Process Data in Batches: The "Loop Over Items" (Split in Batches) node helps efficiently process multiple items, such as a list of workflows, in manageable chunks.
5. Apply Conditional Logic: The Switch node allows for branching the workflow based on specific conditions, enabling different actions depending on the data.
6. Merge Data: The Merge node can combine data streams from different branches of the workflow.
7. Edit Data Fields: The "Edit Fields (Set)" node is used to modify, add, or remove fields from the data flowing through the workflow.
8. Perform HTTP Requests: The HTTP Request node allows for interaction with any external API, useful for more complex GitHub API calls or other services.
9. No Operation: The "No Operation, do nothing" node acts as a placeholder or a terminal point for branches where no further action is required.

Prerequisites/Requirements

• n8n Instance: An active n8n instance to import and run the workflow.
• GitHub Account: A GitHub account and a repository where you intend to save your workflows.
• GitHub Credential in n8n: You will need to set up a GitHub credential in your n8n instance to allow the workflow to authenticate with your GitHub account.

Setup/Usage

1. Import the Workflow:
   • Copy the provided JSON content.
   • In your n8n instance, go to "Workflows" and click "New".
   • Click the three dots menu (...) in the top right and select "Import from JSON".
   • Paste the JSON content and click "Import".
2. Configure Credentials:
   • Locate the "GitHub" node in the workflow.
   • Click on the node and configure your GitHub credentials. If you don't have one set up, click "Create New" and follow the prompts to authenticate with your GitHub account.
3. Customize Workflow Logic:
   • The "Function" node (ID 14) is a placeholder for your custom JavaScript logic. You will need to modify this node to define how you want to retrieve and format your n8n workflows.
   • The "GitHub" node (ID 16) and "HTTP Request" node (ID 19) will need to be configured with the specific GitHub API calls to fetch, create, or update files in your repository. This includes specifying the repository name, file paths, and content.
   • The "Cron" node (ID 7) can be configured to define the schedule at which this workflow should run (e.g., daily, weekly).
   • The "Switch" node (ID 112) can be used to implement conditional logic, for example, to check if a workflow file already exists in GitHub before attempting to create it.
   • The "Loop Over Items" (Split in Batches) node (ID 39) is useful if you plan to process multiple workflows from your n8n instance.
4. Activate the Workflow:
   • Once configured, save the workflow.
   • Toggle the workflow to "Active" to enable its scheduled execution.

This workflow provides a flexible foundation. You will need to implement the specific logic within the "Function", "GitHub", and "HTTP Request" nodes to precisely define how your n8n workflows are retrieved and saved to your chosen GitHub repository.
