This changes Angular so that it can be used without reflection (assuming a codegen for injectors).
BREAKIKNG CHANGE:
- Drops `APP_COMPONENT` provider. Instead, inject
`ApplicationRef` and read its `componentTypes` property.
- long form bootstrap has changed into the following:
```
var platform = createPlatform(ReflectiveInjector.resolveAndCreate(BROWSER_PROVIDERS));
var appInjector =
ReflectiveInjector.resolveAndCreate([BROWSER_APP_PROVIDERS, appProviders], platform.injector);
coreLoadAndBootstrap(appInjector, MyApp);
```
BREAKING CHANGE:
- 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(…)`.
This adds the feature for `@ViewChild`/`@ViewChildren`/`@ContentChild`/`@ContentChildren` to define what to read from the queried element.
E.g. `@ViewChild(`someVar`, read: ViewContainerRef)` will locate the element with a variable `someVar` on it and return a `ViewContainerRef` for it.
Background: With this change, Angular knows exactly at which elements there will be `ViewConainerRef`s as the user has to ask explicitly of them. This simplifies codegen and will make converting Angular templates into server side templates simpler as well.
BREAKING CHANGE:
- `DynamicComponentLoader.loadIntoLocation` has been removed. Use `@ViewChild(‘myVar’, read: ViewContainerRef)` to get hold of a `ViewContainerRef` at an element with variable `myVar`.
- `DynamicComponentLoader.loadNextToLocation` now takes a `ViewContainerRef` instead of an `ElementRef`.
- `AppViewManager` is renamed into `ViewUtils` and is a mere private utility service.
Each compile template now exposes a `<CompName>NgFactory` variable
with an instance of a `ComponentFactory`.
Calling `ComponentFactory.create` returns a `ComponentRef` that can
be used directly.
BREAKING CHANGE:
- `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.
Instead of using injectAsync and returning a promise, use the `async` function
to wrap tests. This will run the test inside a zone which does not complete
the test until all asynchronous tasks have been completed.
`async` may be used with the `inject` function, or separately.
BREAKING CHANGE:
`injectAsync` is now deprecated. Instead, use the `async` function
to wrap any asynchronous tests.
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); });
}));
```
Closes#7735
BREAKING CHANGE:
- 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

To workaround https://github.com/Microsoft/TypeScript/issues/7573
we must remove the readonly keyword from generated .d.ts files.
This solution will not scale, but will probably buy enough time to require our users move to a 2.0 beta.
Closes#8003
process.env.TRAVIS_PULL_REQUEST contains a string and not a boolean value, so we need
to compare it to a string literal rather than do boolean arithmetics.
Instead of running with karma and the karma-dart shim, run dart
tests directly using the new package:test runner. This migrates
away from package:unittest.
Fixes a couple tests, mostly associated with depending on absolute
URLs or editing the test providers after an injector had already
been created.
Remove karma-dart and associated files. Change gupfiles to run tests
via `pub run test` instead.

This allows you to specify a regex and serializer function instead
of the path DSL in your route declaration.
```
@RouteConfig([
{ regex: '[a-z]+.[0-9]+',
serializer: (params) => `{params.a}.params.b}`,
component: MyComponent }
])
class Component {}
```

BREAKING CHANGE:
`OnPushObserve` was an experimental
feature for Dart and had
conceptual performance problems,
as setting up observables is slow.
Use `OnPush` instead.
BREAKING CHANGE:
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.
Closes#7262
