you can refactor this :

        if (userData.role === 'admin') {
          token = jwt.sign(userData, process.env.SECRET_COOKIE);
          response.writeHead(200, {
            'content-type': 'text/plain',
            'Set-Cookie': `accessToken=${token}`
          });
          response.end('/admin');
        } else {
          token = jwt.sign(userData, process.env.SECRET_COOKIE);
          response.writeHead(200, {
            'content-type': 'text/plain',
            'Set-Cookie': `accessToken=${token}`
          });
          response.end('/home');

to be like this :

          token = jwt.sign(userData, process.env.SECRET_COOKIE);
          response.writeHead(200, {
            'content-type': 'text/plain',
            'Set-Cookie': `accessToken=${token}`
          });

        if (userData.role === 'admin') {
           response.end('/admin');
         } else {
          response.end('/home');
