Description

Following the conversation in #37063, this PR is an exploration into enabling focus restoration when navigating back

Changes:

  • added basic location history stack (necessary for implementing focus restoration):
    • refactored the Navigator component, especially the shape of the context object: it now exposes location (the current location), push (used to navigate to a new location), and pop (used to navigate to the previous location)
    • refactored usages across gutenberg
  • enhanced focus restoration:
    • prior to this PR, each NavigatorScreen would focus its first tabbable element when mounted
    • this PR adds logic to attempt to restore focus on a specific element when navigating back (with a fallback on the first tabbable element, as it already happens)
    • updated Storybook example to take advantage of that
    • note that, as of now, the element that will receive focus is targeted via querySelector, and it is the responsibility of the developer to make sure that each link can be correctly selected by providing a working selector.

TODO:

  • edit Storybook example to add a standard NavigatorLink
  • add/update Navigator's unit tests
  • update Navigator README and JSDocs (including the @examples)
  • add CHANGELOG entry

How has this been tested?

  • [TODO] Unit tests
  • Check that the Storybook example works as expected (both focus restoration and back/forward navigation)
  • Check that the Global Styles Sidebar in the site editor works as expected (both focus restoration and back/forward navigation)
  • Check that the Preferences Modal in the post editor (on mobile screens) works as expected (both focus restoration and back/forward navigation)

Types of changes

New feature (technically not breaking, since the component is experimental)

Not sure if you're aware of this, but we've recently done other approach to try to implement a custom client side router in the side editor. See #36488 for the basic implementation and #37314 for focus management and some refactor.

The approach we take there is to make it browser-first, and use the history package to manage the routing for most parts. We can easily switch back to in-memory router by changing createBrowserHistory to createMemoryHistory.

Even though we currently don't have the need to implement a real browser-based client side router, I think it's still good to take it into account in case we ever have the requirement to do so.

Maybe we could combine the two into this component and learn from each other?

@kevin940726 yeah browser navigation has actually been part of the initial implementation of the Navigator component but we felt that it's not something that is needed in all use-cases and not something that should be backed into a UI component, for this reason we decided to built a generic UI component and still have an API that allow syncing with browser history if needed for non-mobile/web apps like edit-site. The original prototype here #32923 has a mechanism to sync navigation state with history that could serve as inspiration.

Hey @kevin940726 and @youknowriad , I created #37355 to discuss the interaction between Navigator and the client-side route in the site-editor package separately, so that we can keep the conversation here focused on the changes in this PR

@ciampo ciampo force-pushed the try/navigator-restore-focus-on-back-link branch from 11a72bb to ba08a42 Compare December 14, 2021 21:47

I don't have any more feedback in this PR, I'm really satisfied with how this is shaping up. Would be good to get a bit more testing and 🚢

This is great to hear! I was initially thinking of splitting the changes in this PR into 3 separate PRs for ease of review/track-ability — they could be:

  • Refactor Navigator to support location history
  • Add support for focus restoration
  • Introduce NavigatorLink and NavigatorBackLink

Would you be ok with that? Otherwise I can just continue the work in this PR (adding unit tests, refining docs...) before asking other folks for a final review.

@ciampo whatever works best for you. The current size of the PR is still manageable/easily reviewable but if you want to ship some things more quickly, go split it :)

In that case, I'm going to close this PR. I will open a few smaller PRs instead — thank you again for your feedback so far!
