What’s the difference between REST and GraphQL?

Over the past decade, the complexity of data requirements on the web has increased, leading to the emergence of GraphQL as a flexible alternative to REST APIs. Originally developed at Facebook, GraphQL allows for more dynamic data querying by enabling the frontend to specify exactly what data is needed through a single endpoint, contrasting with REST's need for multiple specific endpoints. This adaptability addresses the challenges REST faces in meeting rapid frontend changes, particularly in mobile environments where data size impacts application speed. GraphQL facilitates faster development and iterations by reducing backend workload through its Schema Definition Language (SDL), which outlines data structure access. While REST APIs remain prevalent, GraphQL is gaining traction for its ability to streamline application building and improve productivity, with increasing support from cloud-based providers integrating it into their offerings.
