Answer 1

I was having same issue on production on digital ocean droplet. I was using axios in ReactJS to call Node.js API.

Although I included cors

const cors = require('cors');
app.use(cors());

But I still had to add

res.header( "Access-Control-Allow-Origin" );

before calling out my controller. And it worked for me. There I realized that cors is not working properly. So I uninstalled and installed them again and It Works!

Complete code is here.

So either you use

 app.use(function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
  res.header("Access-Control-Allow-Headers", "x-access-token, Origin, X-Requested-With, Content-Type, Accept");
  next();
});

or use

app.use(cors());

It's the same.
