Answer 1

In app.listen you passed wrong port means you intialized port as 8080 but passed 80

app.listen(8080,() =>{
    console.log(`The application started and the port is ${port}`);
});

Basically, app.use function uses a middleware when a particular API is called it does not a get request.

So try app.get instead of app.use it will work.

app.get('/static', (req, res) => {
  // Do your stuffs.
  return res.send(response)
})
