Building a Write-Once Publishing Pipeline

The problem

Writing content is the easy part, while consistently publishing it across platforms with correct metadata and updates is a common challenge. Current workflows often involve manual copy-pasting and reformatting, leading to lost updates and tracking issues.

Why This Matters

Maintaining content consistency across multiple platforms is technically complex, often relying on error-prone manual processes. The cost of inconsistent content can range from brand confusion to SEO penalties, potentially impacting user engagement and revenue.

Key Insights

• Idempotency is crucial: The pipeline is designed to be safely run repeatedly without unintended side effects.
• Git as Source of Truth: Utilizing Markdown in Git as the single source of truth simplifies content management and version control.
• PostgreSQL for State Tracking: A PostgreSQL database tracks publication status and content hashes for reliable updates and prevents duplication.

Practical Applications

• Personal Bloggers: Automate publishing to platforms like WordPress, Dev.to, and Substack from a single Markdown source.
• Pitfall: Relying on manual updates across platforms leads to inconsistencies and broken links, damaging credibility.
