Description
GraphQL is a query language for APIs and a runtime for executing those queries with existing data. It provides a more efficient, powerful, and flexible alternative to REST. With GraphQL, you can define the structure of the data required, and the server returns exactly what was requested. It allows clients to specify exactly what data they need, which makes it simpler than traditional REST APIs where the server defines what is returned. This makes it easier to evolve APIs over time and enables powerful developer tools. Skills in GraphQL range from understanding its basic syntax and setting up a server to designing complex schemas, optimizing performance, and securing servers.
