Front End React Application with User Authentication

Comment

There are two main things your React application needs to do to sign on a user: Get an access token from an authentication server. Send the access token to your backend server with each subsequent request.

const jwt = require("jsonwebtoken");

function authenticateToken(req, res, next) {
  // Read the JWT access token from the request header
  const authHeader = req.headers["authorization"];
  const token = authHeader && authHeader.split(" ")[1];
  if (token == null) return res.sendStatus(401); // Return 401 if no token

  // Verify the token using the Userfront public key
  jwt.verify(token, process.env.USERFRONT_PUBLIC_KEY, (err, auth) => {
    if (err) return res.sendStatus(403); // Return 403 if there is an error verifying
    req.auth = auth;
    next();
  });
}
