There is a SPA on React.js and Node.js, how to implement a page change?

Question

JavaScript

There is a SPA on React.js and Node.js, when the button is pressed, a fetch request is sent to the server, a response arrives and you need to do a redirect along with it, but then Cannot GET / is displayed, because the files go through app.use(express.static ...), and the URL on that page is already different, but how can I write it so that a get request for any URL still issues index.html? I'm new to backend so sorry if this is a stupid question.

Answer 1

app.get('*', function(req, res){
  res.sendfile(__dirname + '/public/index.html');
});

These three lines are at the very end. And don't forget to change the path to index.html
