LifeCycle can now be imported via angular2/angular2 or
angular2/core, so that end users can inject it without
having to use the full source path.
Closes#3395
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
Move the implementation of `(de)hydrate`, `hydrated`, and
`detectChangesInRecords` into `AbstractChangeDetector`.
Add comments clarifying the contract between `AbstractChangeDetector`
and its subclasses.
Closes#3245
Move fields common to Dynamic, Jit, and Pregen change detectors into the
`AbstractChangeDetector` superclass to save on codegen size and reduce
code duplication.
Update to #3248, closes#3243
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
Call new `(de)hydrateDirectives` methods from `(de)hydrate`. Add a null
implementation in `AbstractChangeDetector` and only override if
necessary for the specific change detector.
Update to #3248
Create `looseNotIdentical => !looseIdentical`, which will save a lot of
unnecessary '!' characters in generated change detectors.
Update to https://github.com/angular/angular/issues/3248
Reverted from commit 35597a8349
This style change makes the docs look nicer but clang-format doesn't
like it. @mhevery perhaps we can tweak the clang-format rules for this?
Previously, `uninitialized()` was a method, requiring a call as well as
two extra characters everywhere it was used.
Make this value a variable, saving the characters and avoiding the
method call to get its value.
This change also removes the export of `uninitialized` from
change_detect.ts, which is technically a breaking change, however
`uninitialized` is an implementation detail and nobody should be using
it in app logic. By convention, apps should not be importing from files
under `src/`.
Update to #3248.
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
Create `NameRegistry`, responsible for understanding how names are
generated for change detector fields and variables.
Use `NameRegistry` for both JS Jit & Dart pre-generated detectors.
Making progress on #3248
Previously, the compiler would detect cycles where there were none just because of other components that were compiled in parallel. Furthermore, the way ProtoView merging was triggered could result into early exits resulting in errors when trying to instantiate ProtoViews.
Fixes#3206Closes#3211
BREAKING CHANGE
Previously it was possible to pass a custom error reporter to bootstrap, which was used only during the construction of Injector. This had limited utility, so this capability has been removed.
BREAKING CHANGES:
Dart applications and TypeScript applications meant to transpile to Dart must now
import `package:angular2/bootstrap.dart` instead of `package:angular2/angular2.dart`
in their bootstrap code. `package:angular2/angular2.dart` no longer export the
bootstrap function. The transformer rewrites imports of `bootstrap.dart` and calls
to `bootstrap` to `bootstrap_static.dart` and `bootstrapStatic` respectively.
When a `Directive` implements a lifecycle interface (e.g. `OnChange` or
`OnInit`), populate its `lifecycle` property if not already populated).
Closes#3181
Static binary component tree of depth 10, i.e. 1024 components.
Current numbers for `pureScriptTime` are:
JavaScript:
Baseline: 27.10+-9%
Ng2: 26.84+-8%
Ng1: 55.30+-14%
Dart:
Baseline: 30.13+-4%
Ng2: 45.94+-3%
Ng1: 128.88+-10%
I.e. in JS we are same speed as baseline right now!
Some background: We had a recent change in the compiler that merges components into their parents already during compilation (#2529). This made Ng2 2x faster in this benchmark (before the Ng2 JS time was 49.59+-14%ms).
Closes#3196
Don't precompile Dart2JS for pull requests, instead serve the dart
sources with pub serve. We were already testing with Dartium so
all we lose is some test coverage of defects exposed only by the
Dart2JS transpiler.
This still runs the dart transformer.
Fixes#3030
BREAKING CHANGE
The @Parent annotation has been removed. Use @Ancestor instead.
@Parent was used to enforce a particular DOM structure (e.g., a pane component is a direct child of the tabs component).
DI is not the right mechanism to do it. We should enforce it using schema instead.
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.
Due to #3019 we have to check whether a property exists on a DOM element
not before runtime of the application.
Previously, we did this check in JavaScript, making all property values
go through dart js interop. However, this is slow for complex objects.
This commit changes this behavior to first check whether the property exists
before sending the property value to the DOM element via js interop.
Closes#3149
Previously, calls to getBaseHref used document.baseURI, which defaults
to the current path in the absence of a base element in the document.
This leads to surprising behavior.
With this change, getBaseHref returns null when a base element is not
present in the document.
Implement deferred libraries to work with dependency injection and other
angular codegen. This is done by not initializing the library in the parent
ng_deps file when it is declared as deferred, rewriting the import and,
chaining a future that initializes the library in any files that are using
deferred libraries which need angular codegen.
BREAKING CHANGES:
`ViewManager.createView` / `ViewContainerRef.create` have been split into 2 methods:
- `createHostView` which takes dynamically created bindings
- `createEmbeddedView` which takes the newly introduced `TemplateRef`
The new type `TemplateRef` is the combination of a `ProtoViewRef` and and `ElementRef`
from the same place. Use `TemplateRef` when working with embedded views in
`ng-if`, `ng-for`, ... instead of `ProtoViewRef`.
Also, `ProtoViewRef` is no more injectable, but `TemplateRef` is.
First part of #1989 to clean up manual content projection.
Closes#3114
Fix sort order for reflective imports in reflection_remover/rewriter.dart.
Currently there is only one import so the sort order happens to be correct,
but if another one is added the rewrite code will break.
Remove reflector parameter from initReflector method to simplify ng_deps for reflection
initialization. It wasn't used and was added for testability, but wasn't used. This
keeps the interface simplier.
In Dart, '$' indicates the beginning of an interpolation.
- Escapes '$' in strings when generating change detector classes.
- Adds a unit test to cover this case.
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 CHANGE:
This change renames all instances of PipeRegistry to Pipes.
As part of this change, the former "defaultPipes" export is
now a Pipes instance, instead of a map. The map that was previously
called "defaultPipes" no longer exists, but may be accessed via
defaultPipes.config.
This is its own commit so that tools have an easier time of preserving
history of the file, by keeping the diff between pipes.ts and
pipe_registry.ts minimal.
Also moved pipe_registry_spec.ts
The properties of the annotation classes are not really the public API.
Users will interact with these via a decorator, and the decorator
takes a single arg, typed with the args class. Thus the comment is
more useful on the arg class.
This also fixes the problem of intellisense/autocomplete not showing
the important docs as you fill in the properties in a decorator
declaration.
We had the same symbol exported as the interface
for Component decorator as well as the class for
Component annotation, and dgeni only showed the
latter.
Rename the interfaces for decorators with an ‘I’
prefix so they are retained in the .d.ts output.
Previously, when a return type was missing it
could have been any. But following #2746 we
require return types so remaining untyped returns
must be void.
In non-transformed mode the funcOrValue check was enough, but once
transformed these all use the same function for getters, so we need
to also check the name.
BREAKING CHANGE:
The Http module previously would return RxJS Observables from method calls
of the Http class. In order to support Dart, the module was refactored to
return the EventEmitter abstraction instead, which does not contain the same
combinators or subscription semantics as an RxJS Observable. However, the
EventEmitter provides a toRx() method which will return an RxJS Subject,
providing the same subscription and combinator conveniences as were
available prior to this refactor.
This is temporary, until issue #2794 is resolved, when Observables will
again be returned directly from Http class methods.
The BaseRequestOptions class is responsible for declaring default values,
while the RequestOptions class is merely responsible for setting values
based on values provided in the constructor.
BREAKING CHANGE: HttpFactory is no longer available.
This factory provided a function alternative to the `request` method of the
Http class, but added no real value. The additional factory required an
additional IHttp interface, an odd way to inject while preserving type information
(`@Inject(HttpFactory) http:IHttp`), and required additional documentation in the
http module.
Closes#2564
add test in gulpfile which will compile a basic TS file with generated
angular2.d.ts to ensure generated d.ts is valid syntactic TS
Adds support for enums in .d.ts generation pipeline.
Removes renaming reexports in http module.
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).
