How to Enable CORS in node JS app on the server side

Simple thing will be to enable Core middleware, like the below

const cors = require('cors')

app.use(function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
  next();
});

app.get('/', cors(), (request, response) => {
  response.send('OK, am up!')
})
