What to do after reloading the js page if the History API is used?

Question

JavaScript

The bottom line is this: the History API is used on the main page of the site. If the url changes from example.com to example.com/contacts, then when we reload the page, we obviously get a 404 error, because the server is trying to return the page that is located at this url, which is not there, because we have a Single Page Application.
Is there any way out other than the obvious - to generate a page on the server?

Answer 1

redirect the request using the web server

Answer 2

redirect all requests to index.html (by means of a web server), and in index.html just parse the url from the browser (location.pathname) and load the piece that matches the url
