After the introduction of the view engine, we can drop a lot of code that is not used any more.
This should reduce the size of the app bundles because a lot of this code was not being properly tree-shaken by today's tools even though it was dead code.
- Don’t use the animation renderer if a component
used style encapsulation but no animations.
- The `AnimationRenderer` should be cached in the same
lifecycle as its delegate.
- Trigger names need to be namespaced per component type.
When the `enableLegacyTemplate` is set to `false`, `<template>` tags and the
`template` attribute are no more used to define angular templates but are
treated as regular tag and attribute.
The default value is `true`.
In order to define a template, you have to use the `<ng-template>` tag.
This option applies to your application and all the libraries it uses. That is
you should make sure none of them rely on the legacy way to defined templates
when this option is turned off (`false`).
BREAKING CHANGE: Because all lifecycle hooks are now interfaces
the code that uses 'extends' keyword will no longer compile.
To migrate the code follow the example below:
Before:
```
@Component()
class SomeComponent extends OnInit {}
```
After:
```
@Component()
class SomeComponent implements OnInit {}
```
we don't expect anyone to be affected by this change.
Closes#10083
Use `RendererV2` instead of `Renderer` now. `Renderer` can still be injected
and delegates to `RendererV2`.
Use `RendererFactoryV2` instead of `RootRenderer`. `RootRenderer` cannot be used
anymore.
BREAKING CHANGE:
- `RootRenderer` cannot be used any more, use `RendererFactoryV2` instead.
Note: `Renderer` can still be injected/used, but is deprecated.
Currently styles are rendered to the root component element, which ensures they're cleaned up automatically
when the client application is bootstrapped. This is less than ideal as progressive rendering can cause HTML
to be rendered before the CSS is loaded, causing flicker.
This change returns to rendering <style> elements in the <head>, and introduces a mechanism for removing
them on client bootstrap. This relies on associating the server and client bootstrap. Another way to think
of this is that the client, when bootstrapping an app, needs to know whether to expect a server rendered
application exists on the page, and to identify the <style> elements that are part of that app in order
to remove them.
This is accomplished by providing a string TRANSITION_ID on both server and client. For most applications,
this will be achieved by writing a client app module that imports BrowserModule.withServerTransition({appId: <id>}).
The server app module will import this client app module and therefore inherit the provider for
TRANSITION_ID. renderModule[Factory] on the server will validate that a TRANSITION_ID has been provided.
TypeScript compiler will now build to ES2015 code and modules. Babili is used to minify ES2015
code, providing an initial optimization that we couldn't previously get just from Uglify. Uses
Babel to convert ES2015 to UMD/ES5 code, and Uglify to minimize the output.
Included refactoring:
- splits the `RendererV2` into a `RendererFactoryV2` and a `RendererV2`
- makes the `DebugRendererV2` a private class in `@angular/core`
- remove `setBindingDebugInfo` from `RendererV2`, but rename `RendererV2.setText` to
`RendererV2.setValue` and allow it on comments and text nodes.

- PlatformState provides an interface to serialize the current Platform State as a string or Document.
- renderModule and renderModuleFactory are convenience methods to wait for Angular Application to stabilize and then render the state to a string.
- refactor code to remove defaultDoc from DomAdapter and inject DOCUMENT where it's needed.
BREAKING CHANGE: Classes that derive from `AsyncPipe` and override
`transform()` might not compile correctly. Use of `async` pipe in
templates is unaffected.
Mitigation: Update derived classes of `AsyncPipe` that override
`transform()` to include the type parameter overloads.

BREAKING CHANGE:
- `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.

Tsickle transforms typescript code, which can change the location of code.
This can cause issues such as runtime stack traces reporting that errors
were raised on the incorrect line in the orginal source. This change replaces
the DecoratorDownlevelCompilerHost and the TsickleCompilerHost with tsickle's
TsickleCompilerHost, which automatically composes tsickle's source maps with
typescript's source maps, so that line numbers are correctly reported at
runtime.

This commit updates the doc-gen to account
for the changes to the codebase for decorators.
There are actually three kinds of calls that create decorators:
* makeDecorator
* makePropDecorator
* makeParamDecorator
Also, the actual documentation for each
decorator is split between two exported symbols:
* `interface [DecoratorName]` contains the metadata fields
* interface [DecoratorName]Decorator` contains a
"call member" which holds the general description of the decorator.
This processor now identifies all three decorator types, and pulls the
description of the callMember onto the main decorator doc description.
(There are some outstanding interfaces in the angular/angular project that
need to be re-exported from `/angular/modules/@angular/core/src/metadata.ts`
to ensure that the doc-gen is able to access them.)
Closes https://github.com/angular/angular.io/pull/2349
`ComponentFactory`s can now be created from a `ViewDefinitionFactory` via
`RefFactory.createComponentFactory`.
This commit also:
- splits `Services` into `Refs` and `RootData`
- changes `ViewState` into a bitmask
- implements `ViewContainerRef.move`

Note, this affects the underlying class and should not affect usage.
DEPRECATION:
- the `NgFor` class is now deprecated. Use `NgForOf<T>` instead.
IMPORTANT: Only the `NgFor` class is deprecated, not the `ngFor`
directive. The `*ngFor` and related directives are unaffected by
this change as references to the `NgFor` class generated from
templates will be automatically converted to references to
`NgForOf<T>` without requiring any template modifications.
- `TrackByFn` is now deprecated. Use `TrackByFunction<T>` instead.
Migration:
- Replace direct references to the `NgFor` class to `NgForOf<any>`.
- Replace references to `TrackByFn` to `TrackByFunction<any>`.
BREAKING CHANGE:
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.

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.

This patch adds the gulp command of `validate-commit-messages`
which will validate the range of commits messages present in the
active branch.
This check now runs on CI as part of the linting checks.
Allowed commit message types and scopes are controlled via commit-message.json file
and documented at https://github.com/angular/angular/blob/master/CONTRIBUTING.md#-commit-message-guidelines
This solution is based on old Vojta's code that he wrote for angular/angular.js, that was later adjusted
by @matsko in #13815.
Ideally we should switch over to something like https://www.npmjs.com/package/commitplease
as suggested in #9953 but that package currently doesn't support strict scope checking,
which is one of the primarily goal of this PR.
Note that this PR removes support for "chore" which was previously overused
by everyone on the team.
