GitHub Trending Daily Summary: OpenAI + HTML Report to DingTalk (n8n)

Get a daily GitHub Trending digest—auto-generated by AI and delivered to DingTalk/Feishu with a public HTML report

This n8n workflow fetches GitHub Trending (daily) repositories every morning, summarizes them using an OpenAI-compatible Chat Completions API, publishes a polished one-page HTML report, and posts the link to your DingTalk and/or Feishu group bots.

What this workflow does

• Runs daily at 09:00 via a cron schedule to start the reporting cycle.
• Downloads the GitHub Trending (daily) page and parses the top N repositories, including stars, forks, primary language, and stars gained today.
• Optionally fetches each repo’s README from raw.githubusercontent.com and trims it to a configured character limit.
• Calls an OpenAI-compatible Chat Completions endpoint to generate a JSON briefing with per-repository insights.
• Renders a styled single-file HTML report from the AI output (or falls back to a raw list if the AI call fails).
• Uploads the HTML to htmlhoster and retrieves a public entry URL.
• Sends signed webhook messages to DingTalk and/or Feishu including a short summary, top projects, and the report link.

Use cases

• SaaS teams that want a daily view of GitHub Trending to guide engineering and product research.
• Automation engineers needing an AI-enhanced GitHub insights report distributed to internal chat groups.
• Operators who want a consistent, shareable HTML dashboard link posted automatically each day.
