Automate Weekly Tutorials from Trending GitHub Repos with Gemini AI to WordPress

This n8n workflow automates the process of generating and publishing weekly tutorials based on trending GitHub repositories. It leverages Google Gemini AI to create engaging content and then publishes it directly to a WordPress site.

What it does

This workflow streamlines the content creation process by:

1. Triggering Weekly: The workflow is scheduled to run periodically (e.g., once a week) to check for new trending topics.
2. Fetching Trending Repositories: It makes an HTTP request to a GitHub API endpoint to retrieve a list of trending repositories.
3. Processing Trending Repos: It iterates through the list of trending repositories, likely extracting key information like repository name, description, and stars.
4. Generating Tutorial Content with AI: For each trending repository, it uses the Google Gemini Chat Model to generate a comprehensive tutorial. This likely includes an introduction, steps, code examples, and a conclusion.
5. Formatting Content: A Code node is used to format the AI-generated content into a suitable structure for a WordPress post.
6. Publishing to WordPress: The formatted tutorial is then published as a new post on a connected WordPress site.
7. Sending Email Notification (Optional/Error Handling): An email notification node is present, which could be used for success notifications, error alerts, or for human review in a "Human in the Loop" (HITL) scenario.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• GitHub Account/API Access: To fetch trending repositories (though a public endpoint might be used).
• Google Gemini API Key: For the Google Gemini Chat Model to generate AI content.
• WordPress Website: With administrator access to publish posts.
• SMTP Server Credentials: If you intend to use the "Send Email" node for notifications.

Setup/Usage

1. Import the Workflow:
   • Download the provided JSON file.
   • In your n8n instance, click on "Workflows" in the left sidebar.
   • Click "New" and then "Import from JSON".
   • Paste the JSON content or upload the file.
2. Configure Credentials:
   • Google Gemini Chat Model: Configure your Google Gemini API key.
   • WordPress: Set up your WordPress credentials (API key or username/password for basic authentication).
   • HTTP Request: Ensure any necessary authentication for GitHub (if required for the specific trending repo API) is configured.
   • Send Email: Configure your SMTP credentials if you plan to use this node.
3. Review and Customize Nodes:
   • Schedule Trigger (Node 839): Adjust the schedule to your preferred frequency (e.g., daily, weekly).
   • HTTP Request (Node 19): Verify the URL for fetching trending GitHub repositories. You might want to customize parameters like language, date range, etc.
   • Google Gemini Chat Model (Node 1262): Review the prompt used to generate the tutorial content. Customize it to fit your desired tutorial style, length, and focus.
   • Code (Node 834): Examine and modify the JavaScript code to ensure the AI-generated content is formatted exactly as you want it for your WordPress posts (e.g., adding HTML tags, markdown conversion, specific headings).
   • Wordpress (Node 118): Configure the post type, status (draft/publish), categories, tags, and any other WordPress-specific settings.
   • Send Email (Node 11): Customize the recipient, subject, and body of the email for notifications.
4. Activate the Workflow: Once all configurations are complete, activate the workflow.

The workflow will now automatically run on its defined schedule, generate tutorials from trending GitHub repositories, and publish them to your WordPress site.
