A simple CLI to scaffold Express.js starter projects.

import { verifyJWT } from '../lib/auth.js';
import { GlobalError, JWTPayload } from '../types/types.js';
import { Request, Response, NextFunction } from 'express';

export const verifyUserToken = (
  req: Request,
  res: Response,
  next: NextFunction,
): void => {
  const token = req.cookies?.token;
  if (!token) {
    return next();
  }
  try {
    const payload = verifyJWT(token) as JWTPayload;

    if (payload.role === 'admin') {
      return res.redirect('/admin/dashboard');
    }

    return res.redirect('/');
  } catch {
    const error: GlobalError = new Error('Ungültiger Token');
    error.statusCode = 401;
    return next(error);
