That's how I do CORS in express applications, you have to remember about OPTIONS because for some frameworks there are 2 calls for CORS, first one is OPTIONS which checks what methods are available and then there is actual call, OPTIONS require just empty answer 200 OK

js

allowCrossDomain = function(req, res, next) {
  res.header('Access-Control-Allow-Origin', '*');
  res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS');
  res.header('Access-Control-Allow-Headers', 'Content-Type, Authorization, Content-Length, X-Requested-With');
  if ('OPTIONS' === req.method) {
    res.send(200);
  } else {
    next();
  }
};

app.use(allowCrossDomain);
