BREAKING CHANGE:
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.
Closes#5036
This make apps to load quicker with pub serve (only builds what is
needed).
Note that lazy transformers seem to make pub build slower, so we wrap
transformers to force them to be eager in release mode.
Closes#5372
All common directives, forms, and pipes have been moved out of angular2/core,
but we kept reexporting them to make transition easier.
This commit removes the reexports.
BREAKING CHANGE
Before
import {NgIf} from 'angular2/core';
After
import {NgIf} from 'angular2/common';
Closes#5362
Currently, core depends on DomRenderer, which depends on the browser.
This means that if you depend on angular2/core, you will always
pull in the browser dom adapter and the browser render, regardless
if you need them or not.
This PR moves the browser dom adapter and the browser renderer out of core.
BREAKING CHANGE
If you import browser adapter or dom renderer directly (not via angular2/core),
you will have to change the import path.
Fix @Input annotations to work with setter methods in dart, and fix @Output
annotations to work with getter methods in Dart when using transformers.

After discussing it we decided that PLATFORM_ is a better prefix for directives available everywhere in the app.
BREAKING CHANGE
AMBIENT_DIRECTIVES -> PLATFORM_DIRECTIVES
AMBIENT_PIPES -> PLATFORM_PIPES
Closes#5201
This is part of ongoing work to make core platform-independent.
BREAKING CHANGE
All private exports from 'angular2/src/core/facade/{lang,collection,exception_handler}' should be replaced with 'angular2/src/facade/{lang,collection,exception_handler}'.
BREAKING CHANGE
All private exports from 'angular2/src/core/{directives,pipes,forms}' should be replaced with 'angular2/src/common/{directives,pipes,formis}'
Closes#5153
Store dependency import information in a dedicated list in `NgDepsModel`
rather than as a boolean field on `ImportModel`. An `ImportModel` should
not "care" whether it is a .ng_deps.dart import or not -- this
information belongs in `NgDepsModel`.
This simplifies some of the logic around how `NgDepsModel` imports are
processed and eventually output.
- Move zone-related code out of logger.dart and into zone.dart.
- Rename `logger` => `log`.
- Add the ability to specify a zone-local `TemplateCompiler`.
The template compiler update removed the option to run the transformer
without generating change detectors and deprecated the
`generate_change_detectors` transformer parameter.
Now that it has been deprecated for several weeks, remove it from the
transformer code.
Forward `reflectPropertiesAsAttributes` => `reflect_properties_as_attributes`
and add a deprecation warning to `reflectPropertiesAsAttributes`.
Closes#4433
- 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
Match [ViewResolver][]'s semantics for reading template and style values
from `@Component` and `@View` annotations.
We now warn if template and/or style values appear on an `@Component`
annotation and a `@View` annotation is present.

Previously, importing a library twice using different prefixes could
cause the template compiler step to incorrect omit `Directive`
dependencies provided by that library.
Previously, we parsed dependencies out of a the stringified value of
`directives`, which is brittle and error-prone.
Move this parsing into `DirectiveProcessor` where we have the full Dart
ast to help.
Previously, `DeferredRewriter` checked for the existence of
`.ng_deps.dart` files to determine which deferred libraries it needed to
rewrite, requiring that those assets exist at the time it was run.
Update to check for `.ng_meta.json` files instead, which exist after the
`DirectiveProcessor` phase. This allows the `DeferredRewriter` (which
only processes *.dart files) to run in
parallel with `TemplateComplier` (which only processes *.ng_meta.json
files) and `StylesheetCompiler` (which only processes *.css files).
Have DeferredRewriter to check existence of .ng_meta.json assets rather than .ng_deps.dart assets
Update `DirectiveProcessor` and `TemplateCompiler` to generate the
getters, setters, and methods currently generated in `BindGenerator`.
Update `DirectiveMetadataLinker` to output `.ng_meta.json` files instead
of `.ng_deps.dart` files, avoiding full codegen until the last phase.
This allows us to dedupe codegen logic and remove an additional phase
from the transformer.
Now that we can specify `directives` in either `@View` or `@Component`,
we will try to parse from both.
Previously, we would trash any `directives` parsed in the first
annotation upon encountering the second annotation. This ensures that we
maintain that list of `directives` regardless of annotation ordering.
Handle the situation where a `.dart` file generates a `.ng_meta.json`
file but does not register any reflective information.
An example of this would be a file that defines a const list that looks
like a directive alias. The transformer keeps track of this, and creates
a `.ng_meta.json` file but never creates a `.ng_deps.dart` file, which
can result in other files being linked to it and it not defining an
`initReflector` method.
`DeferredRewriter` depends on the presence of `.ng_deps.dart` files,
which do not yet exist in the phase where it was previously run.
Update the transformer phases to fix this and add an integration test to
prevent regression.
Link `NgDeps` & `NgMeta` data in the same phase to avoid unnecessary asset
creation & reading.
Remove `NgMeta#exports` and instead use `NgDeps#exports` to link `NgMeta` files
in `ng_meta_linker.dart`.
Previously, annotations which were const objects (as opposed to const
instance creation expressions) were incorrectly output as instance
creation expressions.
Before:
```
const override() // A const instance creation expression
```
After
```
override // A const instance
```
Closes#4481
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.
Ensure that the transformers are properly declaring all consumed
outputs. In particular, when a transformer overwrites an output, make
sure the transformer calls `consumePrimary` followed by `addOutput` for
that file.
Prevent `DirectiveLinker` from consuming `.ng_deps.json` files. When we
do this, barback incorrectly calculates the available assets for that
phase, resulting in broken builds.
To simplify processing and testing in the future, use protobufs to
represent of `.ng_deps.dart` files rather than always dealing
directly in Dart code.
This update does not actually use the protobuf representation, but this
is a step towards moving all phases to parse and use protobufs rather than
Dart code.
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
When running in Dartium without using transformers (i.e. with a normal
static web server), handle relative template URLs. This works by using
mirrors to get the URL of the library where the component class is
defined.
