Go Beyond the Spec With Custom Directives - Roy Derks, StepZen, an IBM Company The GraphQL Specification is a great document for everyone building and using GraphQL APIs, and always in development. For a reason! One thing where GraphQL services and client tooling are good at, is introducing new and better ways to use GraphQL. Often, they make use of custom directives to extend GraphQL with custom or experimental behavior. In this talk I'll share best practices on using directives in GraphQL, and how builders can use custom directives to add new configurable execution capabilities to GraphQL. GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.
