This package provides TypeScript definitions for react-reconciler, a library that enables building custom React renderers targeting non-DOM environments. It offers crucial type information, ensuring type safety and improved developer experience when working with React's reconciliation algorithm to create renderers for platforms like the terminal, canvas, or native applications. These definitions significantly simplify the integration process, preventing common type-related errors during development. Using this package enhances the overall robustness and maintainability of custom React renderers.
