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.
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.
fixes#5390
Before the change:
// original CSS
:host .foo .bar {...}
.foo .bar {...}
// translated to
[_nghost-shh-2] .foo .bar {...}
.foo[_ngcontent-shh-2] .bar[_ngcontent-shh-2] {...}
Note that `.foo` and `.bar` where not scoped and would then apply to nested components.
With this change those selectors are scoped (as they are without `:host`).
You can explicitly apply the style to inner component by using `>>>` or `/deep/`: `:host >>> .foo`
BREAKING CHANGE:
Exceptions are no longer part of the public API. We don't expect that anyone should be referring to the Exception types.
ExceptionHandler.call(exception: any, stackTrace?: any, reason?: string): void;
change to:
ErrorHandler.handleError(error: any): void;
BREAKING CHANGES:
- `#` and `var` are not supported any more in expressions, use `let`,
- `var-<name>` could not be used any more on templates, use `let-<name>`,
- `var-<name>` could not be used any more to create a reference, use `ref-<name>`.
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.
