Pure pipes as well as arrays and maps are
implemented via proxy functions. This is
faster than the previous implementation
and also generates less code.
BREAKING CHANGE:
- pipes now take a variable number of arguments, and not an array that contains all arguments.
This adds the feature for `@ViewChild`/`@ViewChildren`/`@ContentChild`/`@ContentChildren` to define what to read from the queried element.
E.g. `@ViewChild(`someVar`, read: ViewContainerRef)` will locate the element with a variable `someVar` on it and return a `ViewContainerRef` for it.
Background: With this change, Angular knows exactly at which elements there will be `ViewConainerRef`s as the user has to ask explicitly of them. This simplifies codegen and will make converting Angular templates into server side templates simpler as well.
BREAKING CHANGE:
- `DynamicComponentLoader.loadIntoLocation` has been removed. Use `@ViewChild(‘myVar’, read: ViewContainerRef)` to get hold of a `ViewContainerRef` at an element with variable `myVar`.
- `DynamicComponentLoader.loadNextToLocation` now takes a `ViewContainerRef` instead of an `ElementRef`.
- `AppViewManager` is renamed into `ViewUtils` and is a mere private utility service.
BREAKING CHANGE:
- Renderer:
* renderComponent method is removed form `Renderer`, only present on `RootRenderer`
* Renderer.setDebugInfo is removed. Renderer.createElement / createText / createTemplateAnchor
now take the DebugInfo directly.
- Query semantics:
* Queries don't work with dynamically loaded components.
* e.g. for router-outlet: loaded components can't be queries via @ViewQuery,
but router-outlet emits an event `activate` now that emits the activated component
- Exception classes and the context inside changed (renamed fields)
- DebugElement.attributes is an Object and not a Map in JS any more
- ChangeDetectorGenConfig was renamed into CompilerConfig
- AppViewManager.createEmbeddedViewInContainer / AppViewManager.createHostViewInContainer
are removed, use the methods in ViewContainerRef instead
- Change detection order changed:
* 1. dirty check component inputs
* 2. dirty check content children
* 3. update render nodes
