n8n: Share Trending GitHub from Hacker News to X, LinkedIn

Automate sharing: pull trending GitHub links from Hacker News, draft posts with OpenAI, and publish to X + LinkedIn

This n8n workflow scans the Hacker News homepage every 6 hours for GitHub links, drafts tailored copy with OpenAI for X (Twitter) and LinkedIn, stores everything in Airtable, notifies you in Telegram, then publishes to both social networks automatically.

What this workflow does

• Runs on a schedule (every 6 hours).
• Finds GitHub links on Hacker News by requesting the Hacker News homepage HTML and extracting posts that link to GitHub (capturing the post title, the GitHub URL, and the Hacker News item link).
• Prevents duplicates by looking up each Hacker News post ID in Airtable and filtering out items already saved.
• Reads the GitHub repository page, converts the HTML to Markdown, and sends it to OpenAI to generate JSON containing an X post and a LinkedIn post.
• Validates outputs, saves the draft content to a new Airtable record (including source link, generated Tweet/X copy, and LinkedIn copy), and discards errored results.
• Notifies you via Telegram, waits 5 minutes, then publishes to X and LinkedIn.
• Updates Airtable status after completion (e.g., marking X and LinkedIn as done).

Use cases

• SaaS teams that want a steady stream of tech-focused updates without manual browsing of Hacker News.
• Automation engineers who need a reliable pipeline: Hacker News → GitHub → OpenAI → X + LinkedIn with Airtable tracking.
• Creators and communities curating trending developer tools and repos with consistent messaging.

Technical details

• Integrations/credentials: OpenAI, Airtable (Personal Access Token), Telegram, X (Twitter) OAuth2, LinkedIn OAuth2.
• Workflow logic: code, no op, wait, merge, filter, and twitter-related publishing steps.
• Airtable fields: Post ID, Title, Url, Tweet, LinkedIn, plus status fields (e.g., TDone and LDone).
