Use a Custom 404 Page

On this page

You can replace the default 404 page that MongoDB Realm displays when a user tries to access a resource that does not exist with a custom HTML document. You can specify this custom 404 page from the Realm UI or by importing an application configuration directory that includes the page in its hosting directory. Select the tab below that corresponds to the method you want to use.

Note
404 Errors in Single-Page Apps

When single-page application hosting is enabled, Realm always returns an HTTP 200 response with the app root regardless of the requested route. This means that you cannot specify a custom 404 page for a SPA. Instead, you should include custom code in your application to handle invalid routes.
