GraphQL in Motion gets you started building GraphQL-based APIs for new and existing web and mobile applications. Featuring expert presenter Tyler Reckart and dozens of high-quality video lessons, you'll practice as you go and start using what you learn immediately.
GraphQL in Motion teaches you to use GraphQL to build easy-to-manage APIs that radically simplify communication between the components and services that make up a web application. You'll begin by learning how GraphQL fits into various application architectures, including how it compares to REST and other API styles. Following a series of examples, you'll learn to use the GraphQL syntax to write simple data-retrieval queries, dig into schema design, and tackle more advanced challenges like direct data manipulation and error handling. Along the way, you'll find exercises that encourage you to practice as you go so you'll be ready to take on the real world.

In applications with many moving parts, it's a monumental task to keep track of which components and services are responsible for which data at any given time. GraphQL provides an abstraction layer through which you can request data from application services without knowing their underlying architecture. Developed by Facebook to simplify their internal APIs, GraphQL is now available as an open source tool you can use for your own web and mobile applications. Just like REST, GraphQL receives queries and returns resources; however, with GraphQL you can specify the resources you want in a single query without knowing anything about the way the servers are organized. Powerful, fast, and designed with modern development in mind, GraphQL-based systems are more flexible and developer-friendly than traditional REST-based architectures.
