State Management Beyond Redux: Using Zustand for Scalable React Apps

Tutorial May 03, 2025

While Redux remains a powerful tool for state management, there are scenarios where Zustand might be a better fit:

  • Project Size: For small to medium-sized projects, Zustand's simplicity can accelerate development.
  • Team Experience: Teams new to state management may find Zustand's learning curve more approachable.
  • Boilerplate Reduction: If minimizing boilerplate is a priority, Zustand offers a cleaner setup.
  • Performance Needs: Zustand's selective rendering can enhance performance in applications with frequent state updates.

React Performance Optimization Cheatsheet: Hooks, Memoization, and Lazy Loading

Cheatsheet August 20, 2024
javascript

import React from 'react';
import { FixedSizeList as List } from 'react-window';

const Row = ({ index, style }) => (
  <div style={style}>Row {index}</div>
);

function MyList({ itemCount }) {
  return (
    <List
      height={400}
      itemCount={itemCount}
      itemSize={35}
      width={300}
    >
      {Row}
    </List>
  );
}

export default MyList;

This approach drastically reduces the number of rendered DOM nodes, improving performance when dealing with large datasets.

React Custom Hook for API Requests

  • Reusability: The useFetch hook can be used across different components and applications, reducing code duplication and simplifying API interaction.
  • Loading and Error States: Automatically manages loading and error states, providing a consistent way to handle asynchronous operations.
  • Cleanup Handling: Prevents state updates on unmounted components, reducing potential memory leaks and ensuring stability.
  • Custom Headers: Extend the hook to accept custom headers or authentication tokens in the options parameter.
  • Polling: Implement a polling mechanism by setting up a setInterval within the useEffect for periodically fetching data.
  • Data Transformation: Add a callback function to transform the fetched data before setting it in state.
