What and why?

Gutenberg can be used as a platform/framework to build block editors. Mainly thanks to the @wordpress/block-editor package. That said, the experience today is not as straightforward as it can be. There can be a lot of small gotchas and hacks you need to do in order to achieve the desired result. One of these small things is the need to manually render SlotFillProvider component, this PR bundles this behavior within the BlockEditorProvider component, that way custom block editors don't have to render this extra component.

I've added logic to SlotFillProvider to prevent the provider from being rendered twice that way it's fine for application (like edit-post...) to still continue rendering it at the top level to enable slot fill outside the block editor provider while not duplicating the provider by rendering BlockEditorProvider. I might use the same technique for the ShortcutProvider in a separate PR.

Testing Instructions

1- Nothing really, there shouldn't be any impact.

A more radical idea is to eliminate the SlotFillProvider usages completely. They don't do anything useful anyway.

Rendering a <SlotFillProvider> will create a new slot/fill registry, exposed to its children. The existing registry from the parent will be "shadowed" and invisible. Except that this PR is adding code that is actively preventing this: it's detecting if there is a "non-default" context already present, and if there is, it won't shadow it, but instead the provider will act as noop.

So, the only1 function of <SlotFillProvider> is to replace the "default" slot/fill registry, which does nothing and has all methods implemented as noops, with the "real" registry. And the parent.isDefault check makes sure that there is only one "real" registry, a singleton.

But we can achieve that by putting the "real" registry directly into the "default" context, then there would be no providers, only consumers.

I can't just set the default context to null because that would be a breaking change I believe.

The default context behaves in such a way that all Fills and Slots are rendered, but they are "inert". A fill swallows its children and they will never be rendered. A slot will render its container element but nothing will ever be rendered into it.

If the default context was null, rendering Fills and Slots would crash. But they could be fixed by prefixing all the registerSlot etc. calls with ?..

An open question is, do we really need this "inert" behavior anywhere? Wouldn't it be fine if all the rendered slots and fills were really registered in the default registry?

Footnotes

  1. There's one other function of <SlotFillProvider>: I can render several of them in separate non-nested parts of the React tree, and then each sub-tree has its own slot/fill registry. And they are all isolated from each other. The question is whether we have any practical need for this.

This is what I'm doing for the ShortcutProvider and yeah I'd like this approach.

Then we need to answer two questions:

  1. do we need or want to support the "inert" behavior of slots and fills when there is no provider rendered?
  2. do we need or want to support multiple parallel slot/fill registries that are isolated from each other in different React sub-trees?

If we can answer "no" to both, then eliminating the SlotFillProvider is an easy patch.

I don't think so, if we can still make slot/fill work normally, that would be better IMO

do we need or want to support multiple parallel slot/fill registries that are isolated from each other in different React sub-trees?

This is something I've explored a long time ago, I believe there's no need at the moment though.

So, I think a good path forward would be:

  • put a "real" slot/fill registry in the default value of the context
  • don't use the context provider in Gutenberg, just use the default registry
  • however, we should expose the function to create a new registry, and the context Provider as a public API

That allows using the default registry in most code, and at the same time allows you to override the default if you want to. In tests, but maybe also at other places. You can do registry = createRegistry and <Provider value={ registry }/> if you want to.

That's inline with how other libraries that have a "singleton + context", like @wordpress/data or @wordpress/i18n, also work.
