The web app's dashboard allows teams to manage approvals, while Aurora ensures data correctness and lifecycle management for approval states. The backend uses AWS Lambda workers for notifications, callbacks, and expiration handling.", "body_md": "Nod is an approval API for AI agents, scripts, and workflows.\n\nThe idea is simple:\n\nWe built the web app on **Vercel**. The dashboard lets teams manage:\n\nFor the database, we used **Amazon Aurora PostgreSQL**. Nod needs a strong relational database because approval data must be correct. An approval is not just a UI card. It has a lifecycle.\n\n``` php\npending -> approved\npending -> rejected\npending -> expired\npending -> canceled\n```\n\nAurora stores the source of truth:\n\nThe backend runs on AWS with Lambda workers. One worker sends Slack notifications. Another sends signed callbacks. Another expires old approvals.\n\nA typical flow looks like this:\n\n``` php\nApp or agent\n  -> Nod API\n  -> Aurora PostgreSQL\n  -> Slack or web approval\n  -> Signed callback\n  -> App continues\n```\n\nVercel helped us move fast on the user experience. Aurora gave us the reliable data layer needed for real approvals. Together, they helped us build Nod as infrastructure, not just a demo.", "url": "https://wpnews.pro/news/building-nod-with-vercel-and-amazon-aurora-postgresql", "canonical_source": "https://dev.to/madebyaman/building-nod-with-vercel-and-amazon-aurora-postgresql-4e8g", "published_at": "2026-06-29 18:34:31+00:00", "updated_at": "2026-06-29 18:48:45.916560+00:00", "lang": "en", "topics": ["ai-agents", "developer-tools", "ai-infrastructure"], "entities": ["Nod", "Vercel", "Amazon Aurora PostgreSQL", "AWS", "Lambda"], "alternates": {"html": "https://wpnews.pro/news/building-nod-with-vercel-and-amazon-aurora-postgresql", "markdown": "https://wpnews.pro/news/building-nod-with-vercel-and-amazon-aurora-postgresql.md", "text": "https://wpnews.pro/news/building-nod-with-vercel-and-amazon-aurora-postgresql.txt", "jsonld": "https://wpnews.pro/news/building-nod-with-vercel-and-amazon-aurora-postgresql.jsonld"}}
