Sorry - I must have missed that first paragraph. I agree that the sentence in the @placeholder
sub block makes it quite clear. But the second sentence only makes sense after realizing that there are three states in a @defer
block:
- Waiting: The
@defer
block has not been triggered; conditions not met. The content is not loading. - Loading: The
@defer
is triggered (conditions are met). The deferred content is loading. The@placeholder
block is now hidden and the@loading
block is showing). - Loaded/Ready: The deferred content is loaded and shown. Other sub blocks disappear.
from angular.
IMO adding a simple sentence would help a lot:
The
@loading
block is an optional block that allows you to declare content that will be shown during the loading of any deferred dependencies. The@loading
block replaces the @Placeholder block once loading has been triggered. For example, you could show a loading spinner. Similar to@placeholder
, the dependencies of the@loading
block are eagerly loaded.

I have created a PR for your change @ducin. I think it's a small enough change so that it's hopefully not complicated to merge it 👍 . Let's see what happens!

Closing this issue, since PR #54779 was merged.

Hi,
Placeholder:
The @Placeholder is an optional block that declares content to show before the defer block is triggered.
Loading:
The @Loading block is an optional block that allows you to declare content that will be shown during the loading of any deferred dependencies.
The difference seams quite clear here. The loading block replaces the placeholder onces trigger has fired/loading has started.
