Optimizing State Management in a React App During Migration from Redux to Recoil
I've been researching this but I'm migrating some code and I'm converting an old project and I've been struggling with this for a few days now and could really use some help....... Hey everyone, I'm running into an issue that's driving me crazy... During migration from Redux to Recoil for a client's React application, performance issues arose, particularly with a complex component tree that heavily relies on global state. The application has numerous interconnected components that frequently need to read and update shared state. In Redux, this was manageable, but the switch to Recoil introduced some unexpected latency. I've tried switching to atom-based state management, yet the re-renders seem to be more frequent than anticipated. Here’s a simplified version of my setup: ```javascript import { atom, useRecoilState } from 'recoil'; const userState = atom({ key: 'userState', // unique ID (with respect to other atoms/selectors) default: { name: '', age: 0 }, // default value }); function UserProfile() { const [user, setUser] = useRecoilState(userState); const updateUser = (newData) => { setUser((prev) => ({ ...prev, ...newData })); }; return ( <div> <h1>{user.name}</h1> <button onClick={() => updateUser({ name: 'Alice' })}>Change Name</button> </div> ); } ``` While this approach seems straightforward, every update triggers a re-render in all components that subscribe to `userState`. I’ve also explored using selectors for derived state, thinking it might alleviate some of the performance hits, but the issue persists. Additionally, I checked the implementation of `React.memo` on child components to minimize unnecessary renders. It feels like every optimization suggestion I encounter still results in unwanted performance degradation, especially when the component tree depth increases. Would utilizing `Recoil's` `useRecoilCallback` or leveraging `transaction` methods yield better results? If anyone has run into similar issues or has insights on best practices when transitioning from Redux to Recoil, particularly in a performance-sensitive environment, I would greatly appreciate your guidance! I'd really appreciate any guidance on this. Any help would be greatly appreciated! I'd be grateful for any help. My team is using Javascript for this CLI tool. Is there a better approach? Any suggestions would be helpful.
