React Hooks Deep Dive: Beyond useState and useEffect

Introduction

React Hooks revolutionized how we write React components, making it easier to manage state, side effects, and more. While useState and useEffect are the most commonly used hooks, React provides several other powerful hooks, and you can even create your own custom hooks to encapsulate logic and reuse it across components.

Advanced Built-in Hooks

useContext

Share data easily across your component tree without prop drilling.

useReducer

Manage complex state logic in a predictable way, similar to Redux but built-in.

useMemo & useCallback

Optimize performance by memoizing expensive calculations and functions.

Custom Hooks

Custom hooks let you extract component logic into reusable functions. For example:

import { useState, useEffect } from "react";

function useWindowWidth() {
  const [width, setWidth] = useState(window.innerWidth);
  useEffect(() => {
    const handleResize = () => setWidth(window.innerWidth);
    window.addEventListener("resize", handleResize);
    return () => window.removeEventListener("resize", handleResize);
  }, []);
  return width;
}

Patterns and Best Practices

Prefix custom hooks with use.
Keep hooks pure and focused.
Share logic, not state.
