auth-using-nodejs-express-mongo's Issues

APIs not getting response

I setup and run this project on localhost but not getting response from server side.

Solution
Add this code in main file (index.js) between mongo connection and routes code.

app.all('/*', (req, res, next) => {
  // CORS header support
  res.header("Access-Control-Allow-Origin", "*"); // restrict it to the required domain
  res.header('Access-Control-Allow-Methods', 'GET,POST,PUT,PATCH,DELETE,OPTIONS');
  // Set custom headers for CORS
  res.header('Access-Control-Allow-Headers', 'Content-type,Accept,X-Access-Token,X-Key,Authorization,login_user_id');
  if (req.method == 'OPTIONS') {
    res.status(200).end();
  } else {
    next();
  }
});
