Code Refactoring

• core: allow to provide multiple default testing modules (#15054) (6c8638c)

• upgrade: use ComponentFactory.inputs/outputs/ngContentSelectors (a3e32fb)
• introduce source maps for templates (#15011) (cdc882b)

BREAKING CHANGES

• Perviously, any provider that had an ngOnDestroy lifecycle hook would be created eagerly.

  Now, only classes that are annotated with @Component, @Directive, @Pipe, @NgModule are eager. Providers only become eager if they are either directly or transitively injected into one of the above.

  This also makes all useValue providers eager, which should have no observable impact other than code size.

  EXPECTED IMPACT: Making providers eager was an incorrect behavior and never documented. Also, providers that are used by a directive / pipe / ngModule stay eager. So the impact should be rather small.

• DebugNode.source no longer returns the source location of a node.

  Closes 14013

• core: (since v4 rc.1)

  • Renderer2.setStyle no longer takes booleans but rather a bit mask of flags.

4.0.0-rc.1 (2017-02-24)

We are excited to share 4.0.0-RC.1 with the community. This is a feature-complete pre-release of 4.0.0. Upgrade to get to know the new features to be released in 4.0.0, and to help us validate the release.

It’s important to note that this release has been tested extensively. All Angular applications within Google use the master branch of Angular, so every commit is tested and validated at scale prior to any release.

We Need Your Help

Please give this RC a try and test it with your projects! We have spent a significant amount of time working to ensure that this release is backwards compatible and will work with your existing code, but you may have use cases we haven’t anticipated. If you are broken by this release, let us know so that we can look into it right away. We are also looking for feedback related to the ergonomics of any newly added APIs.

What’s New

View Engine

We’ve made changes under the hood to what AOT generated code looks like. These changes should reduce the size of the generated code for your components by more than half in some cases. Read the Design Doc for the View Engine updates.

Enhanced *ngIf syntax

Our template binding syntax now supports a couple helpful changes. You can now use an if/else style syntax, and assign local variables such as when unrolling an observable.

<ng-template #loading>Loading...</ng-template>
<div *ngIf="userObservable | async; else loading; let user">
  {{ user.name }}
</div>

Animation Package

We have pulled Animations into their own package. This means that if you don’t use Animations, this extra code will not end up in your production bundles. This also allows you to more easily find documentation and to take better advantage of autocompletion. If you do need animations, libraries like Material will automatically import the module (once you install it via NPM), or you can add it yourself to your main NgModule.

TypeScript 2.1

We’ve updated Angular to a more recent version of TypeScript. This will improve the speed of ngc and you will get better type checking throughout your application.

StrictNullChecks

Angular is now compliant with TypeScript’s StrictNullChecks. This means that you can enable StrictNullChecks in your project, if desired.

Universal

Universal, the project that allows developers to run Angular on a server, is now up to date with Angular again, and has been adopted by the Angular team. This release now includes the results of the work from the Universal team over the last few months. The majority of the Universal code is now in platform-server. To learn more about this change, take a look the new renderModuleFactory method, or Rob Wormald’s Demo Repository. More documentation is forthcoming.

Flat ES Modules (Flat ESM / FESM)

We now ship flattened versions of our modules ("rolled up" version of our code in the EcmaScript Module format, see example file). This format should help tree-shaking, help reduce the size of your generated bundles, and speed up build, transpilation, and loading in the browser in certain scenarios.

ES2015 Builds

We now also ship our packages in the ES2015 Flat ESM format. This option is experimental and opt-in (configure your webpack to resolve "es2015" property in package.json over the regular "module" property).

Known Issues

The following is a list of known issues that will be fixed in the next rcs.

• Source maps are missing in npm packages
• Generated bundles will be larger temporarily while we validate new code paths and remove old ones
• angular.io docs have not been updated to reflect API changes in 4.0
• legacy UMD bundles don't have correct RxJS mappings when running in ES5 mode without a module system

Installing RC.1

We have two main ways to update. If you have an existing project, you should be able to run:

On Linux/Mac: npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router,animations}@next --save On Windows: npm install @angular/common@next @angular/compiler@next @angular/compiler-cli@next @angular/core@next @angular/forms@next @angular/http@next @angular/platform-browser@next @angular/platform-browser-dynamic@next @angular/platform-server@next @angular/router@next @angular/animations@next --save

Then run whatever ng serve or npm start command you normally use, and everything should work.

Please ensure that you are using Typescript v2.1.6 or higher.

If you rely on Animations you’ll also need to install the animations package @angular/animations and import the new BrowserAnimationsModule from @angular/platform-browser/animations in your root NgModule. Without this, your code will compile and run, but animations won’t activate. Imports from @angular/core were deprecated, use imports from the new package import { trigger, state, style, transition, animate } from '@angular/animations';.

What's next?

We have three more release candidates scheduled before our planned GA the week of March 22. In the meantime we'll be looking for your feedback, fixing bugs and working on docs.

• core: change abstract classes for interfaces (#12324) (ee747f7), closes #10083

Performance Improvements

• distribute smaller bundled code and include es2015 bundle (de795ea)

BREAKING CHANGES

• core: Because all lifecycle hooks are now interfaces the code that uses 'extends' keyword will no longer compile. Introduced by (ee747f7).

  To migrate the code follow the example below:

  Before:

  @Component()
  class SomeComponent extends OnInit {}
  

  After:

  @Component()
  class SomeComponent implements OnInit {}
  

  Based on our research we don't expect anyone to be affected by this change.

• RootRenderer cannot be used any more, use RendererFactoryV2 instead. Introduced by (ccb636c).

  Note: Renderer can still be injected/used, but is deprecated.

Note: the 4.0.0-rc.0 release on npm accidentally omitted one bug fix, so we cut rc.1 instead. oops :-)

DEPRECATIONS

• core: KeyValueDifferFactory and IterableDifferFactory no longer have ChangeDetectorRef as a parameter. It was not used and has been there for historical reasons. If you call DifferFactory.create(...) remove the ChangeDetectorRef argument. Introduced by (#14311).

BREAKING CHANGES

• common: Classes that derive from AsyncPipe and override transform() might not compile correctly. The much more common use of async pipe in templates is unaffected. We expect no or little impact on apps from this change, file an issue if we break you. Introduced by (#14367) (4da7925).

  • Mitigation: Update derived classes of AsyncPipe that override transform() to include the type parameter overloads.

Performance Improvements

• use abstract keyword where possible to decrease file size. (#14112) (670b680)
• core simplify ReflectiveInjector by removing code for Dart implementation (#14126) (670b680)

BREAKING CHANGES

• common: A definition of Iterable<T> is now required to correctly compile Angular applications. Support for Iterable<T> is not required at runtime but a type definition Iterable<T> must be available.

NgFor, and now NgForOf<T>, already supports Iterable<T> at runtime. With this change the type definition is updated to reflect this support.

Migration:

• add "es2015.iterable.ts" to your tsconfig.json "libs" fields.

Part of #12398

• upgrade: Previously, upgrade/static/downgradeInjectable returned an array of the form:

['dep1', 'dep2', ..., function factory(dep1, dep2, ...) { ... }]

Now it returns a function with an $inject property:

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.

DEPRECATIONS

• 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;

BREAKING CHANGES

• core: - 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();
}

Note

Due to regression in the 2.3.0 release that was fixed by #13464, components that have been compiled using 2.3.0 and published to npm will need to be recompiled and republished.

The >=2.3.1 compiler will issue is the following error if it encounters components compiled with 2.3.0: Unsupported metadata version 2 for module ${module}. This module should be compiled with a newer version of ngc.

We are adding more tests to our test suite to catch these kinds of problems before we cut a release.
