Ambient directives can be configured when bootstraping an application.
Ambient directives can be used in every component of the application without
needing to explicitly list them.
- Changes the `alreadyChecked` flag of AbstractChangeDetector to a new `state` flag.
- Changes all checks of alreadyChecked to check that the state is NeverChecked.
- Set state to Errored if an error is thrown during detection.
- Skip change detection for a detector and its children when the state is Errored.
- Add a test to validate this fixes issue #4323.
Closes#4953
Refactor EventEmitter and Async Facade to match ES7 Observable semantics, properly use RxJS typedefs, make EventEmitter inherit from RxJS Subject. Closes#4149.
BREAKING CHANGE:
- consumers of EventEmitter no longer need to call .toRx()
- EventEmitter is now generic and requires a type - e.g. `EventEmitter<string>`
- EventEmitter and Observable now use the `.subscribe(generatorOrNext, error, complete)` method instead of `.observer(generator)`
- ObservableWrapper uses `callNext/callError/callComplete` instead of `callNext/callThrow/callReturn`
We used to use different external css parsers,
depending on the `DomAdapter`. This lead to
inconsistent behavior and environment specific errors.
Closes#5006Closes#4993
Currently, the only way for a directive to export a validator is by providing a function. This makes it ackward to write validators that depend on directive inputs. In addition to supporting functions as validators, classes implementing the Validator interface are supported too.
- fixes wrapping for object literal keys called `template`.
- spacing in destructuring expressions.
- changes to keep trailing return types of functions closer to their
function declaration.
- better formatting of string literals.
Closes#4828
Example:
var login = new Control("someLogin");
c.setErrors({"notUnique": true});
expect(c.valid).toEqual(false);
expect(c.errors).toEqual({"notUnique": true});
c.updateValue("newLogin");
expect(c.valid).toEqual(true);
BREAKING CHANGE:
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.
Closes#4917
Allow ControlGroups and ControlArrays to contain errors from their level, and
errors from their children. [Design Doc](https://docs.google.com/document/d/1EnJ3-_iFpVKFz1ifN1LkXSGQ7h3A72OQGry2g8eo7IA/edit?pli=1#heading=h.j53rt81eegm4)
BREAKING CHANGE: 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},
}
}
BREAKING CHANGES:
- deprecates these methods in NgZone: overrideOnTurnStart, overrideOnTurnDone, overrideOnEventDone, overrideOnErrorHandler
- introduces new API in NgZone that may shadow other API used by existing applications.
BREAKING CHANGES:
- 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).
We can’t resolve relative urls (e.g. for images) in the compiler as
these urls are meant to be loaded in the browser
(unless we would inline images as base64…).
Also, keep `<link rel=“stylesheet”>` in templates that
reference absolute urls with e.g. `http://`. This
behavior was already present for `@import` rules
within stylesheets.
Closes#4740
This is useful for the compiler tests, but otherwise it's not useful.
Additionally if an application has external templates (as is common) then
we should actually fetch these templates in tests.
Fixes#4539Closes#4682
BREAKING CHANGE
Before
```
<cmp [(prop)]="field"> was desugared to <cmp [prop]="field" (prop)="field=$event">
```
After
```
<cmp [(prop)]="field"> is desugared to <cmp [prop]="field" (prop-change)="field=$event">
```
Closes#4658
Bindings in the component view have to be first, before
bindings of components in the light dom (i.e. have the same
order as used in the `ViewManagerUtils.createView()` method.
Fixes#4522Closes#4523
This was a poorly typed attempt to mimic TypeScript's index signatures,
which we can use instead.
This eliminates a very strange type that we were exposing to users, but
not re-exporting through our public API.
Fixes#4483
BREAKING CHANGE:
- Removes `ChangeDetection`, use a binding for `ChangeDetectorGenConfig` instead
to configure change detection.
- `RenderElementRef.renderBoundElementIndex` was renamed to `RenderElementRef.boundElementIndex`.
- Removes `ViewLoader`, use `XHRImpl` instead.
Closes#3605
BREAKING CHANGE:
- we don't mark an element as bound any more if it only contains text bindings
E.g. <div>{{hello}}</div>
This changes the indices when using `DebugElement.componentViewChildren` / `DebugElement.children`.
- `@Directive.compileChildren` was removed,
`ng-non-bindable` is now builtin and not a directive any more
- angular no more adds the `ng-binding` class to elements with bindings
- directives are now ordered as they are listed in the View.directives regarding change detection.
Previously they had an undefined order.
- the `Renderer` interface has new methods `createProtoView` and `registerComponentTemplate`. See `DomRenderer` for default implementations.
- reprojection with `ng-content` is now all or nothing per `ng-content` element
- angular2 transformer can't be used in tests that modify directive metadata.
Use `angular2/src/transform/inliner_for_test` transformer instead.
- use `$implicit` variable value correctly
- handle `ng-non-bindable` correctly
- add some more assertions to `TemplateCompiler`
- make `CompiledTemplate` const
- fix default value for `@Directive.moduleId`
- add new compiler to application bindings
BREAKING CHANGE:
- `Compiler.compileInHost` and all methods of `DynamicComponentLoader` don’t take `Binding` any more, only `Type`s. This is in preparation for the new compiler which does not support this.
Part of #3605Closes#4346
- Rename `DirectiveMetadata` into `CompileDirectiveMetadata`, merge
with `NormalizedDirectiveMetadata` and remove `ChangeDetectionMetadata`
- Store change detector factories not as array but
directly at the `CompiledTemplate` or the embedded template
to make instantiation easier later on
- Already analyze variable values and map them
to `Directive.exportAs`
- Keep the directive sort order as specified in the
`@View()` annotation
- Allow to clear the runtime cache in `StyleCompiler`
and `TemplateCompiler`
- Ignore `script` elements to match the semantics of the
current compiler
- Make all components dynamically loadable and remove
the previously introduced property `@Component#dynamicLoadable`
for now until we find a better option to configure this
- Don’t allow to specify bindings in `@View#directives` and `@View#pipes` as this was never supported by the transformer (see below for the breaking change)
BREAKING CHANGE:
- don't support DI bindings in `@View#directives` and `@View@pipes` any more in preparation of integrating the new compiler. Use `@Directive#bindings` to reexport directives under a different token instead.
Part of #3605Closes#4314
This change adds a syntax for bootstrapping Angular on a page that allows more fine-grained control of the hierarchy created. platform() creates a platform injector (of which there can only be one). From the platform, .application() creates an Angular application including a Zone and all specified application bindings (e.g. for the DOM, HTTP, Compiler, Renderer, etc). At the application level, .bootstrap() will bootstrap the given component into that application.
Closes#3852
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.
BREAKING 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.
Closes#3966
This change moves many APIs to the angular2/core export.
This change also automatically adds FORM_BINDINGS in
the application root injector.
BREAKING CHANGE:
Many dependencies that were previously exported from specific
APIs are now exported from angular2/core. Affected exports, which
should now be included from angular2/core include:
angular2/forms
angular2/di
angular2/directives
angular2/change_detection
angular2/bootstrap (except for dart users)
angular2/render
angular2/metadata
angular2/debug
angular2/pipes
Closes#3977
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.
BREAKING CHANGE:
ViewQuery no longer supports the descendants flag. It queries the whole
component view by default.
Closes#3973
