RESTful APIs have been around for a while now, but they are flawed. Things like non-CRUD operations, response validation, error handling, in-memory state management etc. just get really hard. This talk covers how GraphQL - a standard that unifies server and client communication - comes to save the day, and why the tooling around it is a game-changer. We will answer the following questions. What is the philosophy behind GraphQL? How do you architect a scalable schema? How can GraphQL boost productivity? How can you avoid common pitfalls? We will then get a GraphQL server up and running together while focusing on exploring real-world patterns for architecting our schema. We will discuss and implement practical steps to improve query performance, error handling and caching. By the end of this talk, you will leave with a working GraphQL server while we explore real-world patterns.
