We built a real-time system for Postgres→React sync using a `LISTEN/NOTIFY` Postgres trigger, GraphQL `@live` queries, a React hook and a custom ORM-inspired GraphQL query builder. Starting from ESP32 microcontroller devices sending MQTT messages and a Node/Postgres backend, we moved from polling to a stand-alone PoC with Yoga, Prisma triggers, and a custom `useLiveQuery` hook. After proving that the PoC was working we integrated with all our existing full-stack apps. So now we have low-latency UI updates, reusable cross-app logic, and easier extension for new sensor values. Great UX and excellent DX.

GraphQL celebrated it's 10 year birthday last year, today it's PostGraphile's turn! Hear from maintainer Benjie about the origins of the project, the lessons learned along the way, and how the project has evolved to meet the needs of its users despite being MIT-licensed OSS.

A relaxed discussion and Q&A with GraphQL TSC member Benjie Gillam. There is excitement in the air as Benjie celebrates the 10th anniversary of his open source project PostGraphile. This is your chance to ask Benjie about GraphQL, what are his preferred workflows, PostGraphile V5, the new GraphQL Golden Path or anything at all including his favourite colour or what he had for breakfast!

The session will be conducted by Taz Singh with participation from the audience.
