angular-cn/CHANGELOG.md

OTHER BREAKING CHANGES

• HTML, style values, and URLs are now automatically sanitized. Values that do not match are escaped or ignored. When binding a URL or style property that would get ignored, bind to a value explicitly marked as safe instead by injection the DOM sanitization service:

  class MyComponent {
    constructor(sanitizer: DomSanitizationService) {
      // ONLY DO THIS FOR VALUES YOU KNOW TO BE SAFE! NEVER ALLOW USER DATA IN THIS!
      this.safeStyleValue = sanitizer.bypassSecurityTrustStyle('rotate(90deg)');
      // then bind to `safeStyleValue` in your template.
    }
  }
  

2.0.0-rc.1 (2016-05-03)

2.0.0-rc.0 (2016-05-02)

This is the first release candidate that contains repackaging of Angular into individual packages one per each feature area.

All of the packages are now distributed under the @angular npm scope. This changes how Angular is installed via npm and how you import the code.

To install Angular for a browser application please use:

npm install --save @angular/core @angular/compiler @angular/common @angular/platform-browser @angular/platform-browser-dynamic rxjs@5.0.0-beta.6 zone.js@0.6.12

To import various symbols please adjust the paths in the following way:

• angular2/core -> @angular/core
• angular2/compiler -> @angular/compiler
• angular2/common -> @angular/common
• angular2/platform/browser -> @angular/platform-browser (applications with precompiled templates) + @angular/platform-browser-dynamic (applications that compile templates on the fly)
• angular2/platform/server -> @angular/platform-server
• angular2/testing -> @angular/core/testing (it/describe/..) + @angular/compiler/testing (TestComponentBuilder) + @angular/platform-browser/testing
• angular2/upgrade -> @angular/upgrade
• angular2/http -> @angular/http
• angular2/router -> @angular/router-deprecated (snapshot of the component router from beta.17 for backwards compatibility)
• new package: @angular/router - component router with several breaking changes

Features

• core: introduce template context (cacdead), closes #8321

OTHER BREAKING CHANGES

• • ViewRef.changeDetectorRef was removed as using ChangeDetectorRefs for EmbeddedViewRefs does not make sense. Use ComponentRef.changeDetectorRef or inject ChangeDetectorRef instead.
• • Before, a EmbeddedViewRef used to have methods for setting variables. Now, a user has to pass in a context object that represents all variables when an EmbeddedViewRef should be created.

• ViewContainerRef.createEmbeddedViewRef now takes a context object as 2nd argument.
• EmbeddedViewRef.setLocal and getLocal have been removed. Use EmbeddedViewRef.context to access the context.
• DebugNode.locals has been removed. Use the new methods DebugElement.references to get the references that are present on this element, or DebugElement.context to get the context of the EmbeddedViewRef or the component to which the element belongs.

• • Depending on if you are using precompiled templates or you are compiling templates on the fly, the setup for the base test providers has changed:

Before:

// Somewhere in test setup
import {setBaseTestProviders} from 'angular2/testing';
import {
  TEST_BROWSER_PLATFORM_PROVIDERS,
  TEST_BROWSER_APPLICATION_PROVIDERS
} from 'angular2/platform/testing/browser';
setBaseTestProviders(TEST_BROWSER_PLATFORM_PROVIDERS,
                     TEST_BROWSER_APPLICATION_PROVIDERS);

After (applications that compile templates on the fly):

// Somewhere in the test setup
import {setBaseTestProviders} from '@angular/core/testing';
import {
  TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
  TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS
} from '@angular/platform-browser-dynamic/testing';
setBaseTestProviders(TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
                     TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);

After (applications with precompiled templates):

// Somewhere in the test setup
import {setBaseTestProviders} from '@angular/core/testing';
import {
  TEST_BROWSER_STATIC_PLATFORM_PROVIDERS,
  TEST_BROWSER_STATIC_APPLICATION_PROVIDERS
} from '@angular/platform-browser/testing';
setBaseTestProviders(TEST_BROWSER_STATIC_PLATFORM_PROVIDERS,
                     TEST_BROWSER_STATIC_APPLICATION_PROVIDERS);

2.0.0-beta.17 (2016-04-28)

Bug Fixes

• changelog: fix changelog script. (c209836)
• compiler: Allow templates to access variables that are declared afterwards. (1e8864c), closes #8261
• core: properly evaluate expressions with conditional and boolean operators (1ad2a02), closes #8235 #8244 #8282

• testing: allow test component builder to override directives from lists (ff2ae7a), closes #7397 #8217

Features

• compiler: ElementSchema now has explicit DOM schema information (d327ac4), closes #8179
• core: separate refs from vars. (d2efac1), closes #7158 #8264

BREAKING CHANGES

The reference #... now always means ref-.

Before:

• Outside of ngFor, a #... meant a reference.
• Inside of ngFor, it meant a local variable.

This pattern was confusing.

After:

• <template #abc> now defines a reference to a TemplateRef, instead of an input variable used inside of the template.
• Inside of structural directives that declare local variables, such as *ngFor, usage of #... is deprecated. Use let instead.
  • <div *ngFor="#item of items"> now becomes <div *ngFor="let item of items">
• var-... is deprecated.
  • use # or a ref- outside of *ngFor
  • for ngFor, use the syntax: <template ngFor let-... [ngForOf]="...">

• tests: manage asynchronous tests using zones (8490921), closes #7735
• view_compiler: codegen DI and Queries (2b34c88), closes #6301 #6567

BREAKING CHANGES

• • pipes now take a variable number of arguments, and not an array that contains all arguments.

• inject can no longer wrap fakeAsync while fakeAsync can wrap inject. So the order in existing tests with inject and fakeAsync has to be switched as follows: Before:

inject([...], fakeAsync((...) => {...}))

After:

fakeAsync(inject([...], (...) => {...}))

You will also need to add the dependency 'node_modules/zone.js/dist/fake-async-test.js' as a served file in your Karma or other test configuration.

• • Injector was renamed into ReflectiveInjector, as Injector is only an abstract class with one method on it

• Injector.getOptional() was changed into Injector.get(token, notFoundValue) to make implementing injectors simpler
• ViewContainerRef.createComponent now takes an Injector instead of ResolvedProviders. If a reflective injector should be used, create one before calling this method. (e.g. via ReflectiveInjector.resolveAndCreate(…).

• • DynamicComponentLoader.loadIntoLocation has been removed. Use @ViewChild(‘myVar’, {read: ViewContainerRef}) to get hold of a ViewContainerRef at an element with variable myVar. Then call DynamicComponentLoader.loadNextToLocation.

• DynamicComponentLoader.loadNextToLocation now takes a ViewContainerRef instead of an ElementRef.
• AppViewManager is renamed into ViewUtils and is a mere private utility service.

• • Compiler is renamed to ComponentResolver, Compiler.compileInHost has been renamed to ComponentResolver.resolveComponent.

• ComponentRef.dispose is renamed to ComponentRef.destroy
• ViewContainerRef.createHostView is renamed to ViewContainerRef.createComponent
• ComponentFixture_ has been removed, the class ComponentFixture can now be created directly as it is no more using private APIs.

• Location and other related providers have been moved out of router and into platform/common. BrowserPlatformLocation is not meant to be used directly however advanced configurations may use it via the following import change. Before:

import {
  PlatformLocation,
  Location,
  LocationStrategy,
  HashLocationStrategy,
  PathLocationStrategy,
  APP_BASE_HREF}
from 'angular2/router';
import {BrowserPlatformLocation} from 'angular2/src/router/location/browser_platform_location';

After:

import {
  PlatformLocation,
  Location,
  LocationStrategy,
  HashLocationStrategy,
  PathLocationStrategy,
  APP_BASE_HREF}
from 'angular2/platform/common';
import {BrowserPlatformLocation} from 'angular2/src/platform/browser/location/browser_platform_location';

• injectAsync is now deprecated. Instead, use the async function to wrap any asynchronous tests.

You will also need to add the dependency 'node_modules/zone.js/dist/async-test.js' as a served file in your Karma or other test configuration.

Before:

it('should wait for returned promises', injectAsync([FancyService], (service) => {
  return service.getAsyncValue().then((value) => { expect(value).toEqual('async value'); });
}));
it('should wait for returned promises', injectAsync([], () => {
  return somePromise.then(() => { expect(true).toEqual(true); });
}));

After:

it('should wait for returned promises', async(inject([FancyService], (service) => {
  service.getAsyncValue().then((value) => { expect(value).toEqual('async value'); });
})));
// Note that if there is no injection, we no longer need `inject` OR `injectAsync`.
it('should wait for returned promises', async(() => {
  somePromise.then(() => { expect(true).toEqual(true); });
}));

• • 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

• transformers: collect information for CompileDiDependencyMetadata (39b6e0e)
• transformers: makes the map of resolved identifiers configurable (0bb10d6), closes #7359

BREAKING CHANGES

• OnPushObserve was an experimental feature for Dart and had conceptual performance problems, as setting up observables is slow. Use OnPush instead.

• In Dart we used to support injecting types with generics. As this feature is hard to implement with the upcoming codegen we are dropping it. Merge cl/115454020 in G3 with this change.

• The $router injectable service has been renamed to $rootRouter

• The recently added binding of the current router to the current component has been renamed from router to $router. So now the recommended set up for your bindings in your routed component is:

{
  ...
  bindings: {
    $router: '<'
  }
}

Features

• angular1_router: allow component to bind to router (0f22dce)
• typings: install es6-shim typings to a location users can reference. (f1f5b45)

BREAKING CHANGES

Transitive typings are no longer included in the distribution.

If you use --target=es5, you will need to add a line somewhere in your application (for example, at the top of the .ts file where you call bootstrap):

///<reference path="node_modules/angular2/typings/browser.d.ts"/>

(Note that if your file is not in the same directory as node_modules, you'll need to add one or more ../ to the start of that path.)

If you have unit tests, you need to install typings in your project using http://github.com/typings/typings And install typings such as jasmine, angular-protractor, or selenium-webdriver to satisfy the type-checker.

If you rely on es6 APIs other than Promises and Collections, you will need to install the es6-shim typing instead of using the tag above. Angular previously exposed typings for the entire ES6 API.

• WebWorker: Add Router Support for WebWorker Apps (8bea667), closes #3563

Performance Improvements

• dart/transform: Only process deferred libs when necessary (f56df65), closes #6745

BREAKING CHANGES

This is a breaking change for unit tests. The API for the DebugElement has changed. Now, there is a DebugElement or DebugNode for every node in the DOM, not only nodes with an ElementRef. componentViewChildren is removed, and childNodes is a list of ElementNodes corresponding to every child in the DOM. query no longer takes a scope parameter, since the entire rendered DOM is included in the childNodes.

Before:

componentFixture.debugElement.componentViewChildren[0];

After

// Depending on the DOM structure of your component, the
// index may have changed or the first component child
// may be a sub-child.
componentFixture.debugElement.children[0];

Before:

debugElement.query(By.css('div'), Scope.all());

After:

debugElement.query(By.css('div'));

Before:

componentFixture.debugElement.elementRef;

After:

componentFixture.elementRef;

BREAKING CHANGES

• Renderer.listen now has to return a function that removes the event listener.

• TemplateRef.elementRef is now read-only.

• Tests are now required to use setBaseTestProviders to set up. Assuming your tests are run on a browser, setup would change as follows. Before:

// Somewhere in test setup
import {BrowserDomAdapter} from 'angular2/src/platform/browser/browser_adapter';
BrowserDomAdapter.makeCurrent

After:

// Somewhere in the test setup
import {setBaseTestProviders} from 'angular2/testing';
import {
  TEST_BROWSER_PLATFORM_PROVIDERS,
  TEST_BROWSER_APPLICATION_PROVIDERS
} from 'angular2/platform/testing/browser';
setBaseTestProviders(TEST_BROWSER_PLATFORM_PROVIDERS,
                     TEST_BROWSER_APPLICATION_PROVIDERS);

BREAKING CHANGES

• Platform pipes can only contain types and arrays of types, but no bindings any more.
• When using transformers, platform pipes need to be specified explicitly in the pubspec.yaml via the new config option platform_pipes.
• Compiler.compileInHost now returns a HostViewFactoryRef

2.0.0-beta.0 somnambulant-inauguration (2015-12-15)

Enjoy!

2.0.0-alpha.55 (2015-12-15)

Bug Fixes

• router: export ROUTER_LINK_DSL_PROVIDER and hide MockPopStateEvent (fc75220)

Features

• core: enable dev mode by default (3dca9d5)

BREAKING CHANGES

• Previously, Angular would run in dev prod mode by default, and you could enable the dev mode by calling enableDevMode. Now, Angular runs in the dev mode by default, and you can enable the prod mode by calling enableProdMode.

2.0.0-alpha.54 (2015-12-15)

Bug Fixes

• bundles: don't include RxJS in System.register bundles (77b7cae)
• bundles: remove ngUpgrade from the angular2.js bundle (283962f), closes #5739 #5854
• bundles: remove polyfills from angular2.js bundle (2983558), closes #5881
• bundles: rename the testing.js bundle to testing.dev.js (d55655f), closes #5899 #5776
• bundles: rename UMD bundles (61b9468), closes #5898

BREAKING CHANGES

• System.register testing bundle was renamed: testing.js -> testing.dev.js

• UMD bundles were renamed:

  • angular2.umd.js -> angular2-all.umd.js
  • angular2-testing.umd.js -> angular2-all-testing.umd.js

• RxJS used to be bundled with Angular 2 code and this is not the case any more. RxJS needs to be loaded explicitly.

• Previously angular2.js, angular2.min.js and angular2.dev.js bundles would have zone.js and reflect-metadata pre-appended. New bundles don't contain zone.js nor reflect-metadata - those external dependencies can be easily loaded into a browser using angular2-polyfills.js

• ngUpgrade related symbols are no longer part of the angular2.js bundle. ngUpgrade has a dedicated upgrade.js bundle now.

  import {Observable} from 'angular2/core'
  

  After

  import {Observable} from 'rxjs/Observable';
  

• The setupWebWorker function exported from angular2/platform/worker_app no longer returns a promise of providers, but instead synchronously returns providers. Related to #5815

• angular2/angular2 was removed. Use the correct import from one of the barrels. E.g. angular2/core, angular2/platform/browser, angular2/common, … Note: This only applies to JavaScript, Dart is not changed.

• The following symbols are not exported from angular2/angular2 any more: UrlResolver, AppRootUrl, getUrlScheme, DEFAULT_PACKAGE_URL_PROVIDER. Use imports from angular2/compiler instead.

2.0.0-alpha.52 (2015-12-10)

Features

• core: case-sensitive camelCase templates (kebab-case removal) (da9b46a)

BREAKING CHANGES

• Angular templates are now case-sensitive and use camelCase instead of kebab-case (dash-case).

  Before:

      <p *ng-if="cond">
      <my-cmp [my-prop]="exp">
      <my-cmp (my-event)="action()">
      <my-cmp [(my-prop)]="prop">
      <input #my-input>
      <template ng-for #my-item [ng-for-of]=items #my-index="index">
  

  After:

      <p *ngIf="cond">
      <my-cmp [myProp]="exp">
      <my-cmp (myEvent)="action()">
      <my-cmp [(myProp)]="prop">
      <input #myInput>`,
      <template ngFor "#myItem" [ngForOf]=items #myIndex="index">

Features

• HtmlLexer: allow "<" in text tokens (aecf681), closes #5550

BREAKING CHANGES

• The existing sfx bundle (angular2.sfx.dev.js) is replaced by UMD bundles: angular2.umd.js and angular2.umd.dev.js. The new UMD bundles dont have polyfills (zone.js, reflect-metadata) pre-appended. Those polyfills can be easily loaded by including the angular-polyfills.js bundle.

• The external-dependencies.js bundle was removed. Use angular-polyfills.js instead.

• Number and content of UMD bundles have changed:

• we only publish one bundle that contains: core, common, platform/browser, http, router, instrumentation and upgrade
• exported names have changed and now:
  • core is exported as ng.core
  • common is exported as ng.common
  • platform/browser is exported as ng.platform.browser
  • http is exported as ng.http
  • router is exported as ng.router
  • instrumentation is exported as ng.instrumentation
  • upgrade is exported as ng.upgrade

• Form directives are exportedAs 'ngForm' (was 'form')

  Before: html <form #f="form">

  After: html <form #f="ngForm">

• rxjs, reflect-metadata, zone.js and es6-shims now must be specified as explicit dependencies of each angular app that uses npm for package management.

  To migrate, please add the following into the "dependencies" section of your package.json:

  "dependencies": {
      ...
  
      "es6-promise": "^3.0.2",
      "es6-shim": "^0.33.3",
      "reflect-metadata": "0.1.2",
      "rxjs": "5.0.0-alpha.11",
      "zone.js": "0.5.8"
  
      ...
  }

BREAKING CHANGES

• <whatever /> used to be expanded to <whatever></whatever>. The parser now follows the HTML5 spec more closely. Only void and foreign elements can be self closed.

• End tags used to be tolerated for void elements with no content. They are no more allowed so that we more closely follow the HTML5 spec.

• Before import * as ng from 'angular2'; After import * as core from 'angular2/core';

• Http's MockBackend is no longer exported from the angular2/http module. It's now available at angular2/http/testing

• Operators and Observables from RxJS (e.g. .map(), .toArray(), .toPromise(), etc ) now need to be explicitly imported (once per operator in your app)

  import {Observable} from 'rxjs/Observable';
  import 'rxjs/add/operator/map';
  import 'rxjs/add/observable/interval';
  
  Observable.interval(1000).subscribe(...);
  
  http.get('foos.json').map(res => res.json()).subscribe(...);

BREAKING CHANGES

• Previously http would only error on network errors to match the fetch specification. Now status codes less than 200 and greater than 299 will cause Http's Observable to error.

• A few private helpers (e.g., platformCommon or applicationCommon) were removed or replaced with other helpers. Look at PLATFORM_COMMON_PROVIDERS, APPLICATION_COMMON_PROVIDERS, BROWSER_PROVIDERS, BROWSER_APP_PROVIDERS to see if they export the providers you need.

• Previously, components that would implement lifecycle interfaces would include methods like "onChanges" or "afterViewInit." Given that components were at risk of using such names without realizing that Angular would call the methods at different points of the component lifecycle. This change adds an "ng" prefix to all lifecycle hook methods, far reducing the risk of an accidental name collision.

  To fix, just rename these methods:

  • onInit
  • onDestroy
  • doCheck
  • onChanges
  • afterContentInit
  • afterContentChecked
  • afterViewInit
  • afterViewChecked
  • Router Hooks
  • onActivate
  • onReuse
  • onDeactivate
  • canReuse
  • canDeactivate

  To:

  • ngOnInit,
  • ngOnDestroy,
  • ngDoCheck,
  • ngOnChanges,
  • ngAfterContentInit,
  • ngAfterContentChecked,
  • ngAfterViewInit,
  • ngAfterViewChecked
  • Router Hooks
  • routerOnActivate
  • routerOnReuse
  • routerOnDeactivate
  • routerCanReuse
  • routerCanDeactivate

  The names of lifecycle interfaces and enums have not changed, though interfaces have been updated to reflect the new method names.

Performance Improvements

• dart/transform: Restrict visibility/mutability of codegen (45b33c5), closes #5009

BREAKING CHANGES

• AMBIENT_DIRECTIVES -> PLATFORM_DIRECTIVES

• AMBIENT_PIPES -> PLATFORM_PIPES

• Previously, the controlsErrors getter of ControlGroup and ControlArray returned the errors of their direct children. This was confusing because the result did not include the errors of nested children (ControlGroup -> ControlGroup -> Control). Making controlsErrors to include such errors would require inventing some custom serialization format, which applications would have to understand. Since controlsErrors was just a convenience method, and it was causing confusing, we are removing it. If you want to get the errors of the whole form serialized into a single object, you can manually traverse the form and accumulate the errors. This way you have more control over how the errors are serialized.

• validators: Allow errors at both the group/array level or their children (28d88c5)

BREAKING CHANGES

ControlGroup.errors and ControlArray.errors have changed

• Before: ControlGroup.errors and ControlArray.errors returned a reduced value of their children controls' errors.
• After: ControlGroup.errors and ControlArray.errors return the errors of the group and array, and ControlGroup.controlsErrors and ControlArray.controlsErrors return the reduce value of their children controls' errors.

Errors format has changed from validators

Now errors from a control or an array's children are prefixed with 'controls' while errors from the object itself are left at the root level.

Example: Given a Control group as follows:

var group = new ControlGroup({
  login: new Control("", required),
  password: new Control("", required),
  passwordConfirm: new Control("", required)
});

Before:

group.errors
{
  login: {required: true},
  password: {required: true},
  passwordConfirm: {required: true},
}

After:

group.errors
{
  controls: {
    login: {required: true},
    password: {required: true},
    passwordConfirm: {required: true},
  }
}

Pipes are now associated right to left

• Before: 1 + 1 | pipe:a | pipe:b was parsed as (1 + 1) | pipe:(a | pipe:b)
• After: 1 + 1 | pipe:a | pipe:b is parsed as ((1 + 1) | pipe:a) | pipe:b

NgZone Moved to Stream/Observable-based callback API

• deprecates these methods in NgZone: overrideOnTurnStart, overrideOnTurnDone, overrideOnEventDone, overrideOnErrorHandler
• introduces new API in NgZone that may shadow other API used by existing applications.

Directives no longer match to variable names

You can no longer use a #foo or a var-foo to apply directive [foo], although it didn't work properly anyway. This commit is fixing breakage caused by the switch to pre-compiler (exact SHA unknown).

Actions no longer support if statements

  After:

  <cmp [(prop)]="field"> is desugared to <cmp [prop]="field" (prop-change)="field=$event">
  

API DEPRECATION

• "DI Binding" terminology has changed to "DI Providers" to avoid conflicts/confusion with data-binding. All commonly used apis that use "bind" or "binding" in the name still work but are deprecated and will be removed in future alpha releases. Please update your code:
  • bind -> provide
  • @Component(bindings: ...) -> @Component(providers: ...)
  • @Component(viewBindings: ...) -> @Component(viewProviders: ...)
  • HTTP_BINDINGS -> HTTP_PROVIDERS
  • JSONP_BINDINGS -> JSONP_PROVIDERS
  • ROUTER_BINDINGS -> ROUTER_PROVIDERS
  • FORM_BINDINGS -> FORM_PROVIDERS
  • ELEMENT_PROBE_BINDINGS -> ELEMENT_PROBE_PROVIDERS
  • NoBindingError -> NoProviderError
  • AbstractBindingError -> AbstractProviderError
  • InvalidBindingError -> InvalidProviderError
  • beforeEachBindings -> beforeEachProviders
  • Binding -> Provider

BREAKING CHANGES

Query

make QueryList notify on changes via an observable

• Before: query.onChange(() => ...);
• After: query.changes.subscribe((iterable) => {});

Router

introduce new navigate method

Previously, router.navigate took a string representing the URL. Now, it accepts an array that mirrors the link DSL. The old navigate method has been renamed to router.navigateByUrl. Either change your navigation calls to use the DSL (preferred) or call router.navigateByUrl instead.

• Before: router.navigate

• After: router.navigateUrl

Pipes

add support for pure pipes By default, pipes are pure. This means that an instance of a pipe will be reused and the pipe will be called only when its arguments change.

Before:

@Pipe({name: 'date'}) class DatePipe {} defines an impure pipe.

After:

@Pipe({name: 'date'}) class DatePipe {} defines a pure pipe. @Pipe({name: 'date', pure: false}) class DatePipe {} defines an impure pipe.

• Before: @Pipe({name: 'date'}) class DatePipe {} defines an impure pipe.
• After: @Pipe({name: 'date'}) class DatePipe {} defines a pure pipe. @Pipe({name: 'date', pure: false}) class DatePipe {} defines an impure pipe.

ViewQuery

Implement query update mechanism based on views.

• ViewQuery no longer supports the descendants flag. It queries the whole component view by default.

Instead of working with finer grained element injectors, queries now iterate through the views as static units of modification of the application structure. Views already contain element injectors in the correct depth-first preorder.

This allows us to remove children linked lists on element injectors and a lot of book keeping that is already present at the view level.

Queries are recalculated using the afterContentChecked and afterViewChecked hooks, only during init and after a view container has changed.

• Before: @ViewQuery(SomeDirective, {descendants: true})) someDirective
• After: @ViewQuery(SomeDirective) someDirective

DI

add support for multi bindings Previously a content binding of a component was visible to the directives in its view with the host constraint. This is not the case any more. To access that binding, remove the constraint.

Core

remove the (^ syntax and make all DOM events bubbling)

• Before

<div (^click)="onEventHandler()">
  <button></button>
</div>

• After

<div (click)="onEventHandler()">
  <button></button>
</div>

Properties/Events (Inputs/Outputs)

Rename Property into Input and Event into Output

• Before: @Directive({properties: ['one'], events: ['two']})

• After: @Directive({inputs: ['one'], outputs: ['two']})

• Before: @Component({properties: ['one'], events: ['two']})

• After: @Componet({inputs: ['one'], outputs: ['two']})

• Before: class A {@Property() one; @Event() two;}

• After: class A {@Input() one; @Output() two;}

Compiler

With a new compiler NgNonBindable is not a directive but rather a special attribute (ng-non-bindable) recognized by the compiler. This means that you can't import / use the NgNonBindable as a directive. You should remove all the imports for the the NgNonBindable directive and all the references to it in the directives section of the @View decorator.

• IS_DARTIUM constant is no longer exported/supported

• The HTTP package is no longer supported in Dart (use standard library apis instead)

• Remove IRequestOptions / IResponseOptions / IQueryList interfaces

• Pipe factories have been removed and Pipe names to pipe implementations are 1-to-1 instead of 1-to-*

  Before:

  class DateFormatter {
  transform(date, args){}
  }
  
  class DateFormatterFactory {
  supporst(obj) { return true; }
  create(cdRef) { return new DateFormatter(); }
  }
  new Pipes({date: [new DateFormatterFactory()]})
  

  After:

  class DateFormatter {
  transform(date, args){}
  }
  new Pipes({date: DateFormatter})
  

• Previously Angular called onDestroy on all pipes. Now Angular calls onDestroy only on pipes that have the onDestroy method.

• Instead of configuring pipes via a Pipes object, now you can configure them by providing the pipes property to the View decorator.

  @Pipe({
  name: 'double'
  })
  class DoublePipe {
  transform(value, args) { return value * 2; }
  }
  @View({
  template: '{{ 10 | double}}'
  pipes: [DoublePipe]
  })
  class CustomComponent {}
  

• The router was previously exported as ng.router in the angular.sfx.dev.js bundle, but now it is exported as ngRouter.

• The selector for the CSSClass directive was changed from [class] to [ng-class]. The directive itself was renamed from CSSClass to NgClass

• change_detection: do not generate onAllChangesDone when not needed (adc2739)
• change_detection: removed the currentProto property (71ea199)

BREAKING CHANGES

• Directives that previously injected Pipes to get iterableDiff or keyvalueDiff, now should inject IterableDiffers and KeyValueDiffers.
  

• Previously, if an element had a property, Angular would update that property even if there was a directive placed on the same element with the same property. Now, the directive would have to explicitly update the native elmement by either using hostProperties or the renderer.

Reverts

• style(ngFor): add whitespace to Directive annotation (74b311a)

BREAKING CHANGES

• 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.

• S: 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.

Performance Improvements

• dom: Only send values for existing properties to js interior (153660f), closes #3149

BREAKING CHANGES

• Pipes.append has been renamed into Pipes.extend.
  

  Pipes.extend prepends pipe factories instead of appending them.

• S:

• 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!

• Renderer.setElementProperty does not take style./... prefixes any more. Use the new methods Renderer.setElementAttribute, ... instead Part of #2476

• 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).

• • Compiler.compile has been removed, the only way to compile components dynamically is via Compiler.compileInHost
