No copy edits to this one, but I removed Dart-specific code, since the
Dart cheatsheet is produced from dart-lang/angular2.
Part of a group of cheatsheet PRs (see #11149).

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>`.
Accessing a property on the window object must be done with square brackets.
Otherwise closure compiler may collide the symbol's alias between the property
and variable mappings.
Also, accessing the 'provide' property must be done with dot syntax, so that
it can be renamed along with the code that declares such a property.
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.
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.
Often it is useful to test a component without rendering certain directives/components
in its template because these directives require some complicated setup.
You can do that by using NO_ERRORS_SCHEMA.
TestBed.configureTestingModule({
schemas: [NO_ERRORS_SCHEMA]
});
This would disable all schema checks in your tests.
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.
When creating a new Headers object using an existing Headers object
the existing Headers map is copied by reference. Therefore adding a
new Header value to the new Headers object also added this value to
the existing Headers object which is not in accordance with the
spec.
This commit alters the constructor to create a deep copy of existing
Headers maps and therefore unlink existing Headers from new Headers.
Closes#6845
BREAKING CHANGE:
any code which relies on the fact that a newly
created Headers object is referencing an existing Headers map is
now broken, but that should normally not be the case since this
behavior is not documented and not in accordance with the spec.
