GraphQL is a great way to expose your APIs, and it has changed the way we think about consuming data over HTTP.

Not only does GraphQL give us the power to ask for exactly what we want, but it also exposes data in a way that is more aligned with the way we humans think about data.

Over the last ten years, GraphQL has progressed from an internal project at Facebook to become the mainstream way for modern applications to interact with the backend. The ecosystem has grown phenomenally, and major players like Amazon, Twitter, Facebook, and Microsoft are committed to GraphQL.

Learn what GraphQL is and what the benefits are of using GraphQL over technologies like REST? Together we will dive deep into GraphQL and explore how it can solve the issues we face with traditional data fetching technologies.

In this talk, we will build a GraphQL backend for a modern application with ASP.NET Core and Hot Chocolate. We will dive into GraphQL mutation, GraphQL subscriptions, and DataLoader; we will look at what is coming next in GraphQL with defer and stream, client-controlled nullability, and OneOf Input Objects.

As we look at everyday use cases, we will learn GraphQL’s best practices and patterns.

If you like, bring your laptop and code along as we not only look at the concepts but go headfirst and apply them in some coding exercises.
