How does jsonwebtoken.default work?

jsonwebtoken.default is a library that provides a set of functions for creating, signing, and verifying JSON Web Tokens (JWTs) in web applications.

The library allows a developer to generate a JWT that contains a set of claims, such as a user ID, username, and expiration time. These claims can be used to authenticate and authorize users in web applications.

To create a JWT, the library provides a sign() function that takes a set of claims and a secret key as input. The secret key is used to sign the JWT and can be used to verify the JWT later.

To verify a JWT, the library provides a verify() function that takes the JWT and the secret key as input. The function verifies the signature of the JWT and ensures that the claims are valid and have not expired.

The library also provides utility functions for decoding and verifying JWTs without requiring a secret key, as well as for generating random strings and base64-encoded data.

const jwt = require("jsonwebtoken");

// Set the secret key used to sign the JWT
const secret = "mysecretkey";

// Set the claims to be included in the JWT
const claims = {
  userId: 1234,
  username: "john.doe",
  exp: Math.floor(Date.now() / 1000) + 60 * 60, // Token will expire in 1 hour
};

// Create a new JWT using the claims and secret key
const token = jwt.sign(claims, secret);

console.log("JWT:", token);

// Verify the JWT using the secret key
jwt.verify(token, secret, (err, decoded) => {
  if (err) {
    console.error("Error verifying JWT:", err);
  } else {
    console.log("JWT verified successfully:", decoded);
  }
});

In this example, we set the secret key used to sign the JWT to 'mysecretkey'. We then create a set of claims to include in the JWT, such as a userId, username, and an expiration time. We create the JWT using the jwt.sign() function, passing in the claims and secret key, and store the resulting JWT in the token variable. Finally, we verify the JWT using the jwt.verify() function, passing in the JWT and secret key. If the JWT is valid and has not expired, the function will return the decoded claims in the decoded variable. If there is an error with the JWT, such as an invalid signature or expired claims, the function will return an error in the err variable.
