GraphQL Day@ FOST London

Your next million API consumers won't be developers. They'll be AI agents. And they don't read documentation, parse hypermedia links, or guess which of your 200 REST endpoints returns the data they need. Read more…

In this talk, I will explain the core concepts of GraphQL Federation as accessibly as possible. The goal is that you could show this talk to anyone non-technical (such as my wife!) and they'd be able to understand and follow along. Some example topics include what subgraphs and supergraphs are, what entities are, what composition directives are, etc. It will be a fun, interactive (with audience participation!) experience.

You can hand your GraphQL work to an AI agent today, but it tends to make the same mistakes developers have made for years: schemas that are nullable everywhere, anonymous queries, and code that ignores partial errors. Most of the time the model isn't the problem. It just doesn't know your API or your team's conventions, so it guesses. Read more…

Your REST instincts are lying to you. In GraphQL the status code is almost always 200, errors travel in an array alongside your data, and one null in the wrong place can wipe out the entire response. Welcome to the partial response: a successful failure. Read more…

I will talk about "pioneer phase" of GraphQL adoption at HEMA and using AWS AppSync for the composable commerce migration, where I will share the raw and honest lessons learned when introducing a new tech stack to a 100-year-old Dutch icon.
