GraphQL is a query language developed by Facebook to provide a uniform way of fetching application data. It was designed to solve the drawbacks of REST-like APIs, such as lack of type safety and flexibility. GraphQL has a simple structure, enables introspection, and allows for client-side caching and real-time updates. It can be used with existing backends without requiring significant changes. To get started with GraphQL, one can read an introductory article, watch a video that covers the query language, try building a simple server, learn from a tutorial series, or dive deeper into the topic through articles and posts. These resources aim to help developers understand the benefits of GraphQL and how it can make their lives better.
