Currently all playground examples are built with `tsc`
and served with the `gulp serve` task. In order to be able
to test these examples easily with Ivy, we now build and
serve the examples using Bazel. This allows us to expand our
Ivy test coverage and additionally it allows us to move forward
with the overall Bazel migration. Building & serving individual
examples is now very easy and doesn't involve building everything
inside of `/modules`.
PR Close#28490
This patch removes the deprecated support for animation
symbol imports from @angular/core.
BREAKING CHANGE: it is no longer possible to import
animation-related functions from @angular/core. All
animation symbols must now be imported from @angular/animations.
PR Close#22692
Animation triggers can now be set via template bindings `[]`
BREAKING CHANGE:
animation trigger expressions within the template that are assigned as
an element attribute (e.g. `@prop`) are deprecated. Please use the
Angular2 property binding syntax (e.g. `[@prop]`) when assigning
properties.
```ts
// this is now deprecated
<div @trigger="expression"></div>
// do this instead
<div [@trigger]="expression"></div>
```
It is now possible to set a fallback state that will apply its
styling when the destination state is not detected.
```ts
state("*", style({ ... }))
```
