This makes it more consistent with the dynamic version of `upgrade` and makes it
possible to share code between the dynamic and static versions.
This commit also refactors the file layout, moving common and dynamic-specific
files to `common/` and `dynamic/` directories respectively and renaming `aot/`
to `static/`.
Some private keys, used as AngularJS DI tokens, have also been renamed, but this
should not affect apps, since these keys are undocumented and not supposed to
be used externally.
BREAKING CHANGE:
Previously, `upgrade/static/downgradeInjectable` returned an array of the form:
```js
['dep1', 'dep2', ..., function factory(dep1, dep2, ...) { ... }]
```
Now it returns a function with an `$inject` property:
```js
factory.$inject = ['dep1', 'dep2', ...];
function factory(dep1, dep2, ...) { ... }
```
It shouldn't affect the behavior of apps, since both forms are equally suitable
to be used for registering AngularJS injectable services, but it is possible
that type-checking might fail or that current code breaks if it relies on the
returned value being an array.
Make sure that context (`this`) that is passed to functions generated by test helpers is passed through to the callback functions. Enables usage of Jasmine's variable sharing system to prevent accidental memory leaks during test runs.
Allow NgComponentOutlet to dynamically load a module, then load a component from
that module. Useful for lazy loading code, then add the lazy loaded code to the
page using NgComponentOutlet.
Closes#14043
- Introduce `InjectionToken<T>` which is a parameterized and type-safe
version of `OpaqueToken`.
DEPRECATION:
- `OpaqueToken` is now deprecated, use `InjectionToken<T>` instead.
- `Injector.get(token: any, notFoundValue?: any): any` is now deprecated
use the same method which is now overloaded as
`Injector.get<T>(token: Type<T>|InjectionToken<T>, notFoundValue?: T): T;`.
Migration
- Replace `OpaqueToken` with `InjectionToken<?>` and parameterize it.
- Migrate your code to only use `Type<?>` or `InjectionToken<?>` as
injection tokens. Using other tokens will not be supported in the
future.
BREAKING CHANGE:
- Because `injector.get()` is now parameterize it is possible that code
which used to work no longer type checks. Example would be if one
injects `Foo` but configures it as `{provide: Foo, useClass: MockFoo}`.
The injection instance will be that of `MockFoo` but the type will be
`Foo` instead of `any` as in the past. This means that it was possible
to call a method on `MockFoo` in the past which now will fail type
check. See this example:
```
class Foo {}
class MockFoo extends Foo {
setupMock();
}
var PROVIDERS = [
{provide: Foo, useClass: MockFoo}
];
...
function myTest(injector: Injector) {
var foo = injector.get(Foo);
// This line used to work since `foo` used to be `any` before this
// change, it will now be `Foo`, and `Foo` does not have `setUpMock()`.
// The fix is to downcast: `injector.get(Foo) as MockFoo`.
foo.setUpMock();
}
```

CHANGES:
- Remove unused `onDestroy` method on the `KeyValueDiffer` and
`IterableDiffer`.
DEPRECATION:
- `CollectionChangeRecord` is renamed to `IterableChangeRecord`.
`CollectionChangeRecord` is aliased to `IterableChangeRecord` and is
marked as `@deprecated`. It will be removed in `v5.x.x`.
- Deprecate `DefaultIterableDiffer` as it is private class which
was erroneously exposed.
- Deprecate `KeyValueDiffers#factories` as it is private field which
was erroneously exposed.
- Deprecate `IterableDiffers#factories` as it is private field which
was erroneously exposed.
BREAKING CHANGE:
- `IterableChangeRecord` is now an interface and parameterized on `<V>`.
This should not be an issue unless your code does
`new IterableChangeRecord` which it should not have a reason to do.
- `KeyValueChangeRecord` is now an interface and parameterized on `<V>`.
This should not be an issue unless your code does
`new IterableChangeRecord` which it should not have a reason to do.

Detailed changes:
- remove `UNINITIALIZED`, initialize change detection fields with `undefined`.
* we use `view.numberOfChecks === 0` now everywhere
as indicator whether we are in the first change detection cycle
(previously we used this only in a couple of places).
* we keep the initialization itself as change detection get slower without it.
- remove passing around `throwOnChange` in various generated calls,
and store it on the view as property instead.
- change generated code for bindings to DOM elements as follows:
Before:
```
var currVal_10 = self.context.bgColor;
if (jit_checkBinding15(self.throwOnChange,self._expr_10,currVal_10)) {
self.renderer.setElementStyle(self._el_0,'backgroundColor',((self.viewUtils.sanitizer.sanitize(jit_21,currVal_10) == null)? null: self.viewUtils.sanitizer.sanitize(jit_21,currVal_10).toString()));
self._expr_10 = currVal_10;
}
var currVal_11 = jit_inlineInterpolate16(1,' ',self.context.data.value,' ');
if (jit_checkBinding15(self.throwOnChange,self._expr_11,currVal_11)) {
self.renderer.setText(self._text_1,currVal_11);
self._expr_11 = currVal_11;
}
```,
After:
```
var currVal_10 = self.context.bgColor;
jit_checkRenderStyle14(self,self._el_0,'backgroundColor',null,self._expr_10,self._expr_10=currVal_10,false,jit_21);
var currVal_11 = jit_inlineInterpolate15(1,' ',self.context.data.value,' ');
jit_checkRenderText16(self,self._text_1,self._expr_11,self._expr_11=currVal_11,false);
```
Performance impact:
- None seen (checked against internal latency lab)
Part of #13651
- New method `UpgradeAdapter.registerForNg1Tests(modules)` declares the
Angular 1 upgrade module and provides it to the `angular.mock.module()`
helper.
This prevents the need to bootstrap the entire hybrid for every test.
Closes#5462, #12675
- Full support for content projection in downgraded Angular 2
components. In particular, this enables multi-slot projection and
other features on <ng-content>.
- Correctly wire up hierarchical injectors for downgraded Angular 2
components: downgraded components inherit the injector of the first
other downgraded Angular 2 component they find up the DOM tree.
Closes#6629, #7727, #8729, #9643, #9649, #12675
NgIf syntax has been extended to support else clause to display template
when the condition is false. In addition the condition value can now
be stored in local variable, for later reuse. This is especially useful
when used with the `async` pipe.
Example:
```
<div *ngIf="userObservable | async; else loading; let user">
Hello {{user.last}}, {{user.first}}!
</div>
<template #loading>Waiting...</template>
```

Add support for the `$postDigest()` and `$onDestroy()` lifecycle hooks.
Better align the behavior of the `$onChanges()` and `$onInit()` lifecycle hooks
with Angular 1.x:
- Call `$onInit()` before pre-linking.
- Always instantiate the controller before calling `$onChanges()`.
Add upgrade-static.umd.js bundles
This allows depending on it without getting a transitive dependency on compiler.
BREAKING CHANGE:
Four newly added APIs in 2.2.0-beta:
downgradeComponent, downgradeInjectable, UpgradeComponent, and UpgradeModule
are no longer exported by @angular/upgrade.
Import these from @angular/upgrade/static instead.
This commit introduces a new API to the ngUpgrade module, which is compatible
with AoT compilation. Primarily, it removes the dependency on reflection
over the Angular 2 metadata by introducing an API where this information
is explicitly defined, in the source code, in a way that is not lost through
AoT compilation.
This commit is a collaboration between @mhevery (who provided the original
design of the API); @gkalpak & @petebacondarwin (who implemented the
API and migrated the specs from the original ngUpgrade tests) and @alexeagle
(who provided input and review).
This commit is an starting point, there is still work to be done:
* add more documentation
* validate the API via internal projects
* align the ngUpgrade compilation of A1 directives closer to the real A1
compiler
* add more unit tests
* consider support for async `templateUrl` A1 upgraded components
Closes#12239
* feat(forms): ngSubmit event exposes $event from original submit event as local variable
Modify NgForm directive and FormGroup directive to expose the original submit event as $event in the ngSubmit event. Modify docs to reflect changes.
This resolves#10920.
* refactor: code cleanup
This reverts commit 727c2b38a4.
Revert "docs(core): updates query decorator docs"
This reverts commit b6287ccc51.
Revert "docs(core): extract how to examples"
This reverts commit 69e8ace884.
When lazily loading code, users need to be able to get hold of the
NgModuleFactory. For SystemJS environments, the SystemJS registry serves
this purpose. However other environments, such as modules compiled with
Closure compiler, do not expose exports object or a path based registry.
For these environments, `@NgModule` objects can include an identifier, and
the loading code can then pass `loadModule(id).then(() =>
getNgModule(id))` to the router.
BREAKING CHANGE: web worker platform is now exported via separate packages.
Please use @angular/platform-webworker and @angular/platform-webworker-dynamic
