State Management

Local State

Local state in NextJS can be managed using React's built-in useState hook. You can define state variables and update them using the useState hook in functional components.

import { useState } from 'react';

export default function Counter() {
  const [count, setCount] = useState(0);

  const increment = () => {
    setCount(count + 1);
  };

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={increment}>Increment</button>
    </div>
  );
}

The code above shows an example of managing local state in NextJS using the useState hook. The Counter component defines a count state variable and an increment function to update the count value.

Global State

Global state in NextJS can be managed using external state management libraries such as Redux, MobX, React Context API, Recoil, Zustand, or SWR. These libraries provide a way to share state across components and manage complex state interactions in the application.
