Hi i want to share my solution: !!! These code works if you are using a remote server and developing on localhost (webpack or another dev environment) Cheers!!

let ALLOWED_ORIGINS = ["http://serverabc.com", "http://localhost:8080"];
app.use((req, res, next) => {
    let origin = req.headers.origin;
    let theOrigin = (ALLOWED_ORIGINS.indexOf(origin) >= 0) ? origin : ALLOWED_ORIGINS[0];
    res.header("Access-Control-Allow-Origin", theOrigin);
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");

    next();
})
