How to set page title in React?

Question

React

Good afternoon. I am writing a public website in React. Will work with SSR. I am writing a 404 page. I ran into such a problem: so that when clicking on a broken link, search engines understand that the page does not exist, you need to give a 404 header. Is it possible to do this from React?

Answer 1

so then 404 gives the server in the request headers

Answer 2

In routes you need to redirect
