Thanks for this tutorial @francescoxx

When I run this on my machine, although the server is started, it is stuck when calling the endpoint. It does not returning the response.

Im currently using mac with m1 chip. Any pointers about this?

in the index.js, i tried to commented out these lines and it is working now:

// app.use((req, res, next) => {
//     res.setHeader('Access-Control-Allow-Origin', '*');
//     res.setHeader('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE');
// });
Enter fullscreen mode Exit fullscreen mode

I still don't understand what happened. Any pointers / explanation would be appreciated much.

Oh, this is because i missed the next() function call.

app.use((req, res, next) => {
    res.setHeader('Access-Control-Allow-Origin', '*');
    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE');
    next();
});
