Relay Runtime

Relay Runtime is the part of Facebook’s Relay framework that manages how data fetched from a server is handled within a React application. It controls tasks such as fetching data, caching responses, and updating user interface components when data changes. Think of it as the engine that ensures your app displays the right information promptly, without unnecessary network requests or delays. By efficiently coordinating data management, Relay Runtime helps keep your app fast, consistent, and responsive, especially in complex scenarios where multiple data sources and dependencies are involved.
