Expanding on my comment in an answer.
I think this is a very common problem and one I've struggled with myself. I don't think Nicholas Shanks's answer truly solves this.
This section in particular I take some issues with:
The user reloading example.com/resources/1/ is simply re-affirming the current application state, and the client does not need to do any API traversal to get back here.
Your client application should know the current URL, but that URL is saved on the client machine (in RAM, or disk cache, or a history file, etc.)
The implication I take from this, is that urls on your application are only valid for the life-time of the history file or disk cache, and cannot be shared with other users.
If that is good enough for your use-case, then this is probably the simplest, but I feel that there's a lot of cases where this is not true. The most obvious one indeed being the ability to share urls from the frontend-application.
To solve this, I would sum the issue up as:
You need to be able to statelessly map a url from a frontend to an API
The simplest, but incorrect way might simply be to map a API url such as:
Directly to url such as:
The issue I have with this, is that there's an implication that
/resource/1 is taken from the frontend url and just added on to the api url. This is not something we're supposed to do, because it means we can't really evolve this api. If the server decides to link to a different server for example, the urls break.
Another option is that you generate uris such as:
I personally don't think this is too crazy. It does mean that the frontend needs to be able to load that uri and figure out what 'view' to load for the backend uri.
A third possibility is that you add another api that can:
None of these ideas sound super great to me. I want a better solution to this problem, but these are things I came up with as I was contemplating this.
Super curious if there's better ideas out there!
