React Hooks Development Tutorials, Guides & Insights

You can persist state to localStorage or sessionStorage:

import create from 'zustand';
import { persist } from 'zustand/middleware';

const useStore = create(persist(
  (set) => ({
    count: 0,
    increase: () => set((state) => ({ count: state.count + 1 })),
  }),
  {
    name: 'counter-storage',
  }
));

• Avoid unnecessary re-renders: Use React.memo, useMemo, and useCallback to prevent components from re-rendering unnecessarily.
• Use Lazy Loading: Defer loading of components and assets until they are actually needed to improve the initial load time.
• Optimize Large Lists: Use windowing techniques to render only the visible portion of large lists, reducing the rendering workload.
• Profile and Measure: Use React's built-in profiling tools to identify performance bottlenecks and optimize where needed.

React provides a variety of tools and techniques to optimize the performance of your applications. By effectively using Hooks like useMemo and useCallback, employing memoization strategies, and implementing lazy loading, you can ensure that your React applications are both efficient and responsive. This cheatsheet serves as a quick reference to help you implement these optimizations in your projects, leading to faster and more scalable applications.

• 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.
