Unify BlockPreview & BlockPreviewContent into one component #16801

marekhrabe · 2019-07-29T20:57:20Z

Description

This PR updates the way BlockPreview & BlockPreviewContent are used. We want to soon make previews available for plugin developers and these two components were quite confusing together as seen in #16033 (comment).

This PR introduces a new version of BlockPreview which is used for both scaled and full-size previews (controlled by a prop isScaled) and allows you to add custom className to the preview wrapper for further styling if needed.

BlockPreviewContent is gone.

The boolean prop isScaled is a solution that simulates how the component is currently used in the codebase. It will be soon replaced with different way of doing scaling that is being cooked in #16113. For now, I think it's a good solution that will keep our current usages working the same way while paving the way for the new scaling API and exporting the component for devs to use in plugins.

How has this been tested?

in Block Inserter - hover any reusable block. A new "panel" with title "Preview" and the preview itself should show up.
focus some block with styles (button or quote for example):
- check the block settings sidebar and expand "Block Styles" panel. It should contain previews
- open the block switcher and check both thumbnails and also the full preview after hover which should match the styling of the one in block inserter

Screenshots

This is <BlockPreview isScaled blocks={ [ … ] } /> inside Block Styles:

This is the same preview inside the block switcher. The "panel" on the right was moved from the BlockPreview component directly into places where it is being used from (Inserter and Swicther). BlockPreview component is now always only the previewed content and nothing else.

TODO: Block Inserter and Block Switcher both use the "preview on hover" fly-out panel but currently don't share CSS for it in my PR. Let's figure out how to do it (without backing that directly into BlockPreview like before).

~~I'll probably make a wrapper component for BlockPreview which will add the "panel" styling and be used it in both places.~~

I made BlockPreviewDropdownWrapper for this. I'm still wondering if it is the right way.

It is used this way:

<BlockPreviewDropdownWrapper>
  <BlockPreview blocks={ [ … ] } />
</BlockPreviewDropdownWrapper>

but I was wondering whether to made it into something more like HOC which will take the same props as BlockPreview and will pass them internally to the preview. The alternative usage could be something like:

<BlockPreviewForDropdowns blocks={ [ … ] } />

<BlockPreviewForDropdowns blocks={ [ … ] } />

I like the idea of combining the blocks:

<BlockPreviewDropdownWrapper>
  <BlockPreview blocks={ [ … ] } />
</BlockPreviewDropdownWrapper>

However, maybe it worths create the new <PopoverAside /> component to make it usable not only for the BlockPreview one but other components.

I made BlockPreviewDropdownWrapper for this. I'm still wondering if it is the right way.

Forgot to mention that if we want to expose the <BlockPreview /> we will have to expose this one as well, right?

This reverts commit 5bc673e. This reverts commit 3006c01.

I don't mind it to be duplicated in the caller if necessary.

This was my concern and that's why I've introduced the DropdownWrapper to abstract the styling. Knowing this, I've reverted my last commit and we now have a copy of the "aside" in both Inserter and Switcher.

I think all feedback is now addressed here.

I think we may have lost a border around the previews in the change here but tbh I don't think it's worse. It may be better design-wise.

That was intentional :) Glad you noticed. That border just felt extraneous and was so subtle it was barely noticeable anyways.
