Even today, API tooling is mainly limited to docs, SDK generation, API Consoles, and Postman. We at APIs.guru have been working on API tooling for more than 2 years and I think GraphQL is a game-changer in this field. GraphQL doesn’t only formally specify payloads for request and reply but comes loaded with features like introspection, IDL, directives, type-system, etc. In my talk, I want to prove that writing API-tooling has never been easier and that you can build useful things in less than 100 lines. I will buttress up theory with concrete examples from our open-source tools: GraphQL Voyager, GraphQL Faker and a few other tools not yet released. At the end, I will share my vision about “intelligent” API clients and how we can evolve GraphQL to make things that were unthinkable before.
