Bippy: React Internals Hacking Toolkit

Bippy is a specialized JavaScript library designed to provide direct access to React's internal Fiber tree and other non-public APIs, primarily for advanced instrumentation, debugging, and experimental tooling. It operates by emulating React DevTools' hook (`window.__REACT_DEVTOOLS_GLOBAL_HOOK__`) before React itself initializes, thus bypassing standard access restrictions. The current stable version is 0.5.39. While there isn't a fixed release cadence, updates typically occur reactively to maintain compatibility with new React major or minor versions (currently supporting v17-19) as internal structures change. Its key differentiator is providing simplified utility functions to traverse the Fiber tree and extract properties like `memoizedProps`, `memoizedState`, and `dependencies` across different React versions, reducing the need for deep React source code knowledge. It's explicitly not recommended for production applications due to its reliance on unstable internal APIs.
