- 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();
}
```
PR Close#13785
This commit effectively reverts 7e0f02f96e
as it was an invalid fix for #6385, that created a more significant
bug, which was that changes were not always being detected.
Angular 1 digests should be run inside the ngZone to ensure
that async changes are detected.
We don't know how to fix#6385 without breaking change detection
at this stage. That issue is triggered by async operations, such as
`setTimeout`, being triggered inside scope watcher functions.
One could argue that watcher functions should be pure and not do
work such as triggering async operations. It is possible that the
original use case could be supported by moving the debounce
logic into the watch listener function, which is only called if the
watched value actually changes.
Closes#10660, #12318, #12034
PR Close#13812
With the exception of `$onChanges()`, all lifecycle hooks in ng1 are called on
the controller, regardless if it is the binding destination or not (i.e.
regardless of the value of `bindToController`).
This change makes `upgrade` mimic that behavior when calling lifecycle hooks.
Additionally, calling the `$onInit()` hook has been moved before calling the
linking functions, which also mimics the ng1 behavior.
Fix an issue in `registerForNg1Tests`, where it passes a `null` as
`ng1Injector` to `_bootstrapDone`. This causes a "TypeError: Cannot
read property 'get' of null" to be thrown from `_bootstrapDone`.
- 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
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
BREAKING CHANGE: previously deprecated @Component.directives and @Component.pipes support was removed.
All the components and pipes now must be declarated via an NgModule. NgModule is the basic
compilation block passed into the Angular compiler via Compiler#compileModuleSync or #compileModuleAsync.
Because of this change, the Compiler#compileComponentAsync and #compileComponentSync were removed as well -
any code doing compilation should compile module instead using the apis mentioned above.
Lastly, since modules are the basic compilation unit, the ngUpgrade module was modified to always require
an NgModule to be passed into the UpgradeAdapter's constructor - previously this was optional.
We changed the bootstrap order:
1. create NgZone
2. bootstrap ng1 inside NgZone and upgrade ng1 components to ng2 components.
3. bootstrap ng2 with NgZone
Note: Previous footgun behavior was: bootstrap ng2 first to extract NgZone, so that ng1 bootstrap can happen in NgZone. This meant that if ng2 bootstrap eagerly compiled a component which contained ng1 components, then we did not have complete metadata.
BREAKING CHANGE (deprecations)
- Instead of `coreBootstrap`, create an `@AppModule` and use `bootstrapModule`.
- Instead of `coreLoadAndBootstarp`, create an `@AppModule` and use `bootstrapModuleFactory`.
- Instead of `bootstrapWorkerApp`, create an `@AppModule` that includes the `WorkerAppModule` and use `bootstrapModule` with the `workerAppPlatform()`.
- Instead of `bootstrapWorkerUi`, create an @AppModule that includes the `WorkerUiModule` and use `bootstrapModule` with the `workerUiPlatform()` instead.
- Instead of `serverBootstrap`, create an @AppModule and use `bootstrapModule` with the `serverDynamicPlatform()` instead.
- Instead of `PLATFORM_PIPES` and `PLATFORM_DIRECTIVES`, provide platform directives/pipes via an `@AppModule`.
- Instead of `ComponentResolver`:
- use `ComponentFactoryResolver` together with `@AppModule.precompile`/`@Component.precompile` or `ANALYZE_FOR_PRECOMPILE` provider for dynamic component creation.
- use `AppModuleFactoryLoader` for lazy loading.
- Instead of `SystemJsComponentResolver`, create an `@AppModule` and use `SystemJsAppModuleLoader`.
- Instead of `SystemJsCmpFactoryResolver`, create an `@AppModule` and use `SystemJsAppModuleFactoryLoader`
Closes#9726
Every test now has an implicit module. It can be configured via `configureModule` (from @angular/core/testing)
to add providers, directives, pipes, ...
The compiler now has to be configured separately via `configureCompiler` (from @angular/core/testing)
to add providers or define whether to use jit.
BREAKING CHANGE:
- Application providers can no longer inject compiler internals (i.e. everything
from `@angular/compiler). Inject `Compiler` instead. This reflects the
changes to `bootstrap` for module support (3f55aa609f).
- Compiler providers can no longer be added via `addProviders` / `withProviders`.
Use the new method `configureCompiler` instead.
- Platform directives / pipes need to be provided via
`configureModule` and can no longer be provided via the
`PLATFORM_PIPES` / `PLATFORM_DIRECTIVES` tokens.
- `setBaseTestProviders()` was renamed into `initTestEnvironment` and
now takes a `PlatformRef` and a factory for a
`Compiler`.
- E.g. for the browser platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS} from ‘@angular/platform-browser-dynamic/testing’;
setBaseTestProviders(TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);
```
AFTER:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {browserTestCompiler, browserDynamicTestPlatform,
BrowserDynamicTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
browserTestCompiler,
browserDynamicTestPlatform(),
BrowserDynamicTestModule);
```
- E.g. for the server platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS} from ‘@angular/platform-server/testing/server’;
setBaseTestProviders(TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS);
```
AFTER:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {serverTestCompiler, serverTestPlatform,
ServerTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
serverTestCompiler,
serverTestPlatform(),
ServerTestModule);
```

Currently downgraded ng2 elements fail inside a ui-router view because they are unable
to require an ng2 Injector via the require attribute of the DDO, because ui-router compiles
its templates before they are inserted in a ui-view. This adds a "fallback" behavior if
a parent injector cannot be found to go to the root ng2 Injector.
Delays NG1 Directive controller instatiation where possible and pre-link function always
to the ngOnInit() lifecycle hook. This way bindings are always available on $scope in both
the controller and the link function.
