BREAKING CHANGE:
- all `…Metadata` classes have been removed. Use the corresponding decorator
as constructor or for `instanceof` checks instead.
- Example:
* Before: `new ComponentMetadata(…)`
* After: `new Component(…)`
- Note: `new Component(…)` worked before as well.
Every decorator now is made of the following:
- a function that can be used
as a decorator or as a constructor. This function
also can be used for `instanceof` checks.
- a type for this function (callable and newable)
- a type that describes the shape of the data
that the user needs to pass to the decorator
as well as the instance of the metadata
The docs for decorators live at the followig places
so that IDEs can discover them correctly:
- General description of the decorator is placed on the
`...Decorator` interface on the callable function
definition
- Property descriptions are placed on the interface
that describes the metadata produces by the decorator
closes#11145
Also rename `CompileIdentifierMetadata.runtime` into `CompileIdentifierMetadata.reference`.
Also remove `CompileIdentifierMetadata.equalsTo` as
now it is enough to just check the `reference` fields for equality.
ngc can now validate metadata before emitting to verify it doesn't
contain an error symbol that will result in a runtime error if
it is used by the StaticReflector.
To enable this add the section,
"angularCompilerOptions": {
"strictMetadataEmit": true
}
to the top level of the tsconfig.json file passed to ngc.
Enabled metadata validation for packages that are intended to be
used statically.
Until we have comprehensive E2E tests, it's too risky to change the
reflector_host Misko wrote before final. But google3 uses path mapping
and needs all imports to be and all paths to be canonicalized to
the longest rootDir.
This change introduces a subclass of ReflectorHost with overrides for methods
that differ. After final (or when we have good tests), we'll refactor
them back into one class.
Closes#10503
It is possible for code in `beforeEach` to capture and fork a zone
(for example creating `NgZone` in `beforeEach`). Subsequently the code
in `it` may chose to do `fakeAsync`. The issue is that because the
code in `it` can use `NgZone` from the `beforeEach`. it effectively can
escape the `fakeAsync` zone. A solution is to run all of the test in
`ProxyZone` which allows a test to dynamically replace the rules at any
time. This allows the `beforeEach` to fork a zone, and then `it` to
retroactively became `fakeAsync` zone.
Closes#9751
BREAKING CHANGE:
These forms of providers are no longer accepted:
bind(MyClass).toFactory(...)
new Provider(MyClass, toFactory: ...)
We now only accept:
{provider: MyClass, toFactory: ...}
Prior to this change `ngc` would place generated files which refer
to components in the node_modules into the node_module. This is an
issue. Now all of the files are forced into a single directory
as specified in `tsconfig.json` by the `genDir` option.

If a `@NgModule` has a `bootstrap` property, `PlatformRef.bootstrapModule` /
`PlatformRef.bootstrapModuleFactory` will automatically bootstrap the components
listed in there.
If such a property does not exist, `PlatformRef.bootstrapModule` /
`PlatformRef.bootstrapModuleFactory` will try to call the method `ngDoBootstrap(appRef: ApplicationRef)` on the module class.
Otherwise an error is reported.
This makes `bootstrapModuleFactory` wait for promises
returned by `APP_INITIALIZER`s, also making `bootstrapModuleFactory` async.
I.e. now `bootstrapModule` and `bootstrapModuleFactory` behave in the
same way.
This ensures that all code from module instantiation, to creating
`ApplicationRef`s as well as calling `APP_INITIALIZERS` is run
in the Angular zone.
This also moves the invocation of the initializers from the `ApplicationRef`
constructor into the `bootstrapModuleFactory` call, allowing initializers
to get a hold of `ApplicationRef` (see #9101).
