Recoil
Recoil is a state management library for React applications, developed by Facebook. It provides a minimal and flexible API for managing global state in a way that feels native to React, using atoms and selectors to handle shared state across components. It aims to simplify state management by offering predictable updates and efficient re-renders without the boilerplate of other solutions.
Developers should learn Recoil when building medium to large React applications that require complex state management, such as dashboards, data-intensive UIs, or apps with many interdependent components. It is particularly useful for scenarios where state needs to be shared across multiple components without prop drilling, as it offers a more intuitive and performant alternative to Context API for global state. Use cases include real-time data updates, form state management, and user authentication flows.
