In this article, I will show you how to build a JWT server using Node.js and the popular javascript library, jsonwebtoken. The JWT server will allow clients to request and receive JWTs that can be used for authentication.
Here’s an example of how to create a JWT server using Node.js and jsonwebtoken:
Install the required packages
First, we’ll need to install the jsonwebtoken package by running the following command:
npm install jsonwebtoken
Import the jsonwebtoken package
Next, we’ll import the jsonwebtoken package in our Node.js file:
const jwt = require('jsonwebtoken');
Define a secret key
The secret key is used to sign and verify the JWT. It should be kept private and secure. For the purpose of this example, we’ll define the secret key as a constant in our Node.js file:
const secret="secretkey";
