An automated GitOps headless CMS pipeline in n8n allowing non-technical editors to update a live production landing page hero image via form submission. The 8-node workflow receives the image, uploads the asset to GitHub via the Contents API, fetches index.html while capturing the blob SHA concurrency token, parses the DOM using HTML CSS selectors to locate the hero element, safely mutates the markup, and pushes an atomic commit back to main—triggering Vercel CI/CD to redeploy the site on its global Edge Network in under 8 seconds.
- Zero-code headless CMS pipeline triggered by an n8n public form upload with binary file parsing
- Two-commit atomic GitOps architecture: asset creation (images/) followed by index.html markup mutation
- Optimistic concurrency control: captures Git blob SHA via GitHub Contents API to eliminate HTTP 422 race conditions
- Robust DOM extraction: utilizes n8n's native HTML node with CSS selector targeting (#hero-img, .hero-bg) over brittle regex parsing
- Automated Vercel CI/CD integration: deploys production builds in 7 seconds with instant Anycast Edge CDN cache purging
- Interactive showcase studio featuring 8-node n8n canvas, live form uploader, embedded sci-fi landing page, and Vercel build console
- Live index.html diff viewer detailing atomic attribute mutation and GitHub REST API v3 payload schema
- Automated 8-point diagnostic test suite verifying form binary parsing, SHA retention, DOM traversal, and deployment triggers
