how to install jsonwebtoken in next js

1. Install the jsonwebtoken library using npm:

npm install jsonwebtoken

1. Import jsonwebtoken in your Next.js file where you intend to use it:

import jwt from 'jsonwebtoken';

1. Use jsonwebtoken in your code to sign and verify tokens:

// Example: Creating a token
const payload = { user_id: 123 };
const secretKey = 'your_secret_key';
const token = jwt.sign(payload, secretKey);

// Example: Verifying a token
const decoded = jwt.verify(token, secretKey);

Note: Replace 'your_secret_key' with your actual secret key. It is crucial to keep your secret key secure and never expose it in your client-side code.

Now you have successfully installed and integrated the jsonwebtoken library into your Next.js project.
