Also inserts comment nodes before/after projected nodes so that text nodes don’t get merged when we serialize/deserialize them.
Closes#3356
First part of #3364
BREAKING CHANGES:
- `ShadowDomStrategy` was removed. To specify the encapsulation of a component use `@View(encapsulation: ViewEncapsulation.NONE | ViewEncapsulation.EMULATED | ViewEncapsulation.NATIVE)`
- The default encapsulation strategy is now `ViewEncapsulation.EMULATED` if a component contains styles and `ViewEncapsulation.NONE` if it does not. Before this was always `NONE`.
- `ViewLoader` now returns the template as a string and the styles as a separate array
Fixes#3001
BREAKING CHANGE:
View renderer used to take normalized CSS class names (ex. fooBar for foo-bar).
With this change a rendered implementation gets a calss name as specified in a
template, without any transformations / normalization. This change only affects
custom view renderers that should be updated accordingly.
Closes#3264
The Angular 2 render compiler can get out of sync between its transformer
execution and its runtime execution, leading to incorrect change detectors with
out-of-order property values. Stable sorting solves this problem (temporarily).
Angular fetches template HTML files outside of the browser's normal parsing flow. As a result, URLs in template files are interpreted relative to the root application, when the components defined by the template files are inserted into the DOM. This change enables a template author to prefix URLs with the string $baseUrl, which will be replaced with the relative base path of the template file.
So for an example template loaded from /component/foo/template.html:
<img src="$baseUrl/logo.png" />
becomes:
<img src="/component/foo/logo.png" />
Addresses #2384.
Closes#2529
BREAKING CHANGES:
- shadow dom emulation no longer
supports the `<content>` tag. Use the new `<ng-content>` instead
(works with all shadow dom strategies).
- removed `DomRenderer.setViewRootNodes` and `AppViewManager.getComponentView`
-> use `DomRenderer.getNativeElementSync(elementRef)` and change shadow dom directly
- the `Renderer` interface has changed:
* `createView` now also has to support sub views
* the notion of a container has been removed. Instead, the renderer has
to implement methods to attach views next to elements or other views.
* a RenderView now contains multiple RenderFragments. Fragments
are used to move DOM nodes around.
Internal changes / design changes:
- Introduce notion of view fragments on render side
- DomProtoViews and DomViews on render side are merged,
AppProtoViews are not merged, AppViews are partially merged
(they share arrays with the other merged AppViews but we keep
individual AppView instances for now).
- DomProtoViews always have a `<template>` element as root
* needed for storing subviews
* we have less chunks of DOM to clone now
- remove fake ElementBinder / Bound element for root text bindings
and model them explicitly. This removes a lot of special cases we had!
- AppView shares data with nested component views
- some methods in AppViewManager (create, hydrate, dehydrate) are iterative now
* now possible as we have all child AppViews / ElementRefs already in an array!
By binding the token `DOM_REFLECT_PROPERTIES_AS_ATTRIBUTES` provided by
the dom_renderer module to `true` in the root injector (i.e. bootstrap()),
all elements whose properties are set by angular will be reflected as
attributes with the prefix "ng-reflect-".
Fixes#2910
Relying on ASI (automatic semicolon insertion)
is allowed in TypeScript because JavaScript allows
it. However, when we run clang-format it doesn’t
understand that these statements are terminated
with a newline and changes the indentation, in bad
cases even breaking the code.
Fixes#817
This fixes several minor indentation issues (instanceof precendence,
type declaration specificity, template string length calculation).
This should also fix some flip-flop situations with template strings.
BREAKING CHANGES:
- rename `ElementRef.domElement` to `ElementRef.nativeElement`
- add `Renderer.getNativeElementSync` to make the app side
less dependent on the dom renderer.
- don’t use `ElementRef.nativeElement` in directives but
use the methods on `Renderer` directly.
- Removed `ElementRef.setAttribute`. Use `Renderer.setElementAttribute` instead.
Closes#2712
Last part of #2476Closes#2476
BREAKING CHANGES:
- Almost all methods in `Renderer` now take a `RenderElementRef` instead
of a `ViewRef` + `boundElementIndex`.
- These methods can be called with the `ElementRef` from the app side
directly.
Closes#2706
Related to #2476
BREAKING CHANGES:
- host actions don't take an expression as value any more but only a method name,
and assumes to get an array via the EventEmitter with the method arguments.
- Renderer.setElementProperty does not take `style.`/... prefixes any more.
Use the new methods `Renderer.setElementAttribute`, ... instead
Part of #2476Closes#2637
BREAKING CHANGE: compiler will throw on binding to non-existing properties.
Till now it was possible to have a binding to a non-existing property,
ex.: `<div [foo]="exp">`. From now on this is compilation error - any
property binding needs to have at least one associated property:
eaither on an HTML element or on any directive associated with a
given element (directives' properites need to be declared using the
`properties` field in the `@Directive` / `@Component` annotation).
Closes#2598
Allows to add or remove previous siblings of text
interpolations (e.g. by added `<script>` tags for
content reproduction, or by removed `<style>` tags).
Also calculates correctly whether an element is
empty.
Fixes#2591
