Update the Angular 2 transformer to recognize
`package:angular2/platform/browser.dart` as the library which exports
the `bootstrap` function.
Update playground, examples, benchmarks, & tests to import bootstrap from
platform/browser.
Closes#7647
Create transformers that allow specifying transformer actions on
specific libraries.
* angular2/transform/codegen: Generates all necessary code.
* angular2/transform/reflection_rewriter: Replaces `bootstrap` calls in
application entry points to remove transitive dart:mirrors import,
resulting in smaller code size & faster execution.
* angular2/transform/deferred_rewriter: Rewrites deferred imports and
`loadLibrary` calls to initialize Angular2 and preserve deferred
operation.
Proper configuration of these three transformers can replace the single
angular2 transformer, resulting in significant performance gains for
builds of large angular2 apps.
Update angular2 itself to declare the codegen transformer, since it has
neither deferred imports nor application entry points.
Remove the undocumented & unused quick_transformer.
BREAKING CHANGE:
`OnPushObserve` was an experimental
feature for Dart and had
conceptual performance problems,
as setting up observables is slow.
Use `OnPush` instead.
Issue raised in PR #6745.
Previously, the transformer name conversion functions could return the
input string on unexpected input, which is almost certainly an error.
`throw` in this case instead, so we know early that something has likely
gone wrong.
Closes#6753
Previously, every .dart file in a package was processed to ensure proper
initialization of deferred loaded libraries.
Update the transformer to avoid processing libraries which we know do
not import any deferred libraries.
Closes#6745
Handle some cases which would previously result in broken code.
- Importing bootstrap.dart deferred
- Using combinators when importing bootstrap.dart
- Importing bootstrap.dart with a prefix
Closes#6749
Previously, we generated the code to initialize the reflector into the
<file>.ng_deps.dart and the compiled template and change detector code
into <file>.template.dart.
Update the transformer to generate all code into <file>.template.dart to
avoid the additional HTTP requests necessary when debugging
applications in Dartium.
BEFORE:
The following would throw in the dev mode because `f` would return a new array when called by checkNoChanges.
@Component({
template: `
{{f()}}
`
})
class A {
f() { return [1]; }
}
AFTER:
The checkNoChanges function compares only primitives types for equality, and deeply compares iterables. Other objects cannot cause checkNoChanges to throw. This means that the dev mode would never fail given a legal program, but may allow some illegal programs.
Previously, template codegen was done asynchronously, which could result
in reflector state being overwritten and leading to compile errors.
Update the codegen to run synchronously to ensure this does not happen.
Closes#6603
Resolve all invalid field override errors, workaround current
reflection limitations in Dart Dev Compiler. todo, hello_world and
key_events samples now work with Dart Dev Compiler.
BREAKING CHANGE: remove TemplateRef.elementRef setter
Closes#6441
Replace uses of `package:code_transformers`, which is only used to
convert from uri to `AssetId`, with calls to the utility methods in
`src/transform/common/url_resolver.dart`.
Closes#5931
In the `TemplateCompiler` phase, avoid reading in the `.ng_meta.json` files of
imported libraries when we can determine that the file we are processing
does not define any `View`s.
Closes#6183
BREAKING CHANGE:
- 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`
- Component view is not yet created when component constructor is called.
-> use `onInit` lifecycle callback to access the view of a component
- `ViewRef#setLocal` has been moved to new type `EmbeddedViewRef`
- `internalView` is gone, use `EmbeddedViewRef.rootNodes` to access
the root nodes of an embedded view
- `renderer.setElementProperty`, `..setElementStyle`, `..setElementAttribute` now
take a native element instead of an ElementRef
- `Renderer` interface now operates on plain native nodes,
instead of `RenderElementRef`s or `RenderViewRef`s
Closes#5993
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.
