ErrorHandler can not throw errors because it will unsubscribe itself from
the error stream.
Zones captures errors and feed it into NgZone, which than has a Rx Observable
to feed it into ErrorHandler. If the ErroHandler throws, then Rx will teardown
the observable which in essence causes the ErrorHandler to be removed from the
error handling. This implies that the ErrorHandler can never throw errors.
Closes#14949Closes#15182Closes#14316
Inlcuded fixes:
- include preamble in generated source map
- always add a mapping for line/col 0 so that the
generated sourcemap is not sparse
- use a uniue sourceUrl for inline templates even
in the AOT case
Update tsickle to version 0.21.6 which fixes a bug where input source maps which specified filenames differently than the names supplied to tsc didn't get composed with tsc's source maps. Also adds a test that the bug was fixed.
Previous to 2.x there were some source maps distrubted, but they didn't go
all the way back to the TypeScript sources and they weren't available for
all JavaScript distrubted to NPM.
With this change source maps will be available for FESM distributions as
well as UMD and will go all the way back to TypeScript sources.
Fixes#15184
Observable subscriptions from previous validation runs should be canceled
before a new subscription is created for the next validation run.
Currently the subscription that sets the errors is canceled properly,
but the source observable created by the validator is not. While this
does not affect validation status or error setting, the source
observables will incorrectly continue through the pipeline until they
complete. This change ensures that the whole stream is canceled.
AsyncValidatorFn previously had an "any" return type, but now it more
explicitly requires a Promise or Observable return type. We don't
anticipate this causing problems given that any other return type
would have caused a runtime error already.
Previously, style values were parsed with a regex that split on /:+/.
This causes errors for CSS such as
div {
background-url: url(http://server.com/img.png);
}
since the regex would split the background-url line into 3 values instead of 2.
Now, the : character is detected with indexOf, avoiding this error.
A test was added to verify the behavior is correct.
Implemented style guide elements to top header bar, side hamburger nav menu, content and search. Consolidated SCSS files to styles folder. Fixed PWA test.
The input may still have focus when the user hits ESC,
causing the search to be hidden.
If the user then clicks on the input again, they would expect
it to reopen the results.
DEPRECATION:
- the arguments `inputs` / `outputs` / `ngContentSelectors` of `downgradeComponent`
are no longer used as Angular calculates these automatically now.
- Compiler.getNgContentSelectors is deprecated. Use
ComponentFactory.ngContentSelectors instead.
E.g. for a component like this:
```
@Component({
template: ‘<ng-content select=“child”></ng-content>’
})
class MyComp {
@Input(‘aInputName’)
aInputProp: string;
@Output(‘aEventName’)
aOuputProp: EventEmitter<any>;
}
```
the `ComponentFactory` will now contain the following:
- `inputs = {aInputProp: ‘aInputName’}`
- `outputs = {aOutputProp: ‘aOutputName’}`
- `ngContentSelectors = [‘child’]`
In order for tsickle's new support for input source maps to work, the tsickleCompilerHost must be used for the initial load of source files, since that's when the inline source maps are read and stripped.
* feat(common): support `as` syntax in template/* bindings
Closes#15020
Showing the new and the equivalent old syntax.
- `*ngIf="exp as var1”`
=> `*ngIf="exp; let var1 = ngIf”`
- `*ngFor="var item of itemsStream |async as items”`
=> `*ngFor="var item of itemsStream |async; let items = ngForOf”`
* feat(common): convert ngIf to use `*ngIf="exp as local“` syntax
* feat(common): convert ngForOf to use `*ngFor=“let i of exp as local“` syntax
* feat(common): expose NgForOfContext and NgIfContext
In v2.x, users had to annotate classes that they intended to use as tokens with `@Injectable`. This is no longer required in v4.x for tokens,
and we now require the constructor parameters of classes annotated
with `@Injectable` to be statically analyzable by ngc.
This commit reduces the error into a warning
if the constructor parameters do not meet this condition.
DEPRECATION:
- Classes annotated with `@Injectable` but whose constructor’s parameter types
are not statically analyzable by ngc will produce a warning.
Closes#15003
Throwing on query changes would be a breaking change compared to v2.
Also discovers a bug with querying manually projected content, see #15117.
