Summary

A previous post discussing frustrations with React Hooks gained significant attention, prompting feedback that reshaped the author's understanding and appreciation of Hooks. Initially, the author sought to abstract API call logic using a reusable Hook, similar to Redux middleware, but faced challenges with the imperative nature of the implementation. Feedback from readers, particularly from Karen Grigoryan, highlighted the need for a more declarative approach, leading to a revised useFetch Hook that leverages useReducer and useCallbackOne for better lifecycle management. This new approach aligns more closely with React's declarative philosophy, focusing on state changes to trigger component updates. The post further explores issues like stale closures and proposes using mutable refs to manage callback references safely, enhancing the reliability of Hooks. Overall, the author reaffirms their appreciation for React's one-way data flow and its ability to streamline complex JavaScript applications.
