100% Serverless Website to Telegram Channel Automation

How any new blog post automatically triggers an instant broadcast to a Telegram channel using zero-cost GitHub Actions.

When maintaining a personal developer blog, one of the most tedious manual tasks is sharing newly published posts across social channels like Telegram.

We have fully automated this workflow! Now, whenever a new Markdown (.md) file is committed to the repository via git push, a real-time notification is instantly broadcasted directly to our Telegram channel—without paying for a 24/7 VPS or third-party webhooks.

How does it work without a dedicated server?

Most developers assume running a Telegram bot requires a continuously running Node.js or Python background service. However, since our codebase lives on GitHub, we leverage GitHub Actions as an ephemeral serverless execution engine!

The Workflow Step-by-Step

  1. Commit Analysis: When a push hits main, our custom Node script (notify-telegram.mjs) parses git diff to identify freshly added .md files.
  2. Frontmatter Extraction: It reads the metadata (title, description, tags) and verifies that draft: true is not set.
  3. Telegram Bot API: The extracted details are formatted into clean HTML markup and dispatched via a secure fetch() request directly to Telegram's sendMessage endpoint.

Conclusion

By combining static JAMstack rendering with event-driven GitHub Actions, we achieve an ultra-fast, zero-maintenance publishing pipeline. Write markdown, push to main, and let the automation handle the rest!
