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.
This allows Angular to error on unknown properties,
allowing applications that don’t use custom elements
to get better error reporting.
Part of #10043
BREAKING CHANGE:
- By default, Angular will error during parsing
on unknown properties,
even if they are on elements with a `-` in their name
(aka custom elements). If you application is using
custom elements, fill the new parameter `@NgModule.schemas`
with the value `[CUSTOM_ELEMENTS_SCHEMA]`.
E.g. for bootstrap:
```
bootstrap(MyComponent, {schemas: [CUSTOM_ELEMENTS_SCHEMA]});
```
This introduces the `BrowserModule` to be used for long form
bootstrap and offline compile bootstrap:
```
@AppModule({
modules: [BrowserModule],
precompile: [MainComponent],
providers: […], // additional providers
directives: […], // additional platform directives
pipes: […] // additional platform pipes
})
class MyModule {
constructor(appRef: ApplicationRef) {
appRef.bootstrap(MainComponent);
}
}
// offline compile
import {bootstrapModuleFactory} from ‘@angular/platform-browser’;
bootstrapModuleFactory(MyModuleNgFactory);
// runtime compile long form
import {bootstrapModule} from ‘@angular/platform-browser-dynamic’;
bootstrapModule(MyModule);
```
The short form, `bootstrap(...)`, can now creates a module on the fly,
given `directives`, `pipes, `providers`, `precompile` and `modules`
properties.
Related changes:
- make `SanitizationService`, `SecurityContext` public in `@angular/core` so that the offline compiler can resolve the token
- move `AnimationDriver` to `platform-browser` and make it
public so that the offline compiler can resolve the token
BREAKING CHANGES:
- short form bootstrap does no longer allow
to inject compiler internals (i.e. everything
from `@angular/compiler). Inject `Compiler` instead.
To provide custom providers for the compiler,
create a custom compiler via `browserCompiler({providers: [...]})`
and pass that into the `bootstrap` method.
Mostly, removing things that were never intended to be exported publicy.
BREAKING CHANGE:
The following are no longer publicly exported APIs. They were intended as internal
utilities and you should use your own util:
```
browserDetection,
dispatchEvent,
el,
normalizeCSS,
stringifyElement,
expect (and custom matchers for Jasmine)
```
This addresses several oversights in assigning security contexts to DOM schema
elements found by our security reviewers (thanks!).
This also adds some more precise unit tests for the interaction between
(Dom)ElementSchemaRegistry and the TemplateParser, and extracts the security
specific parts into dom_security_schema.ts.
Comparison of (potentially) dangerous property names is done case insensitive,
to avoid issues like formAction vs formaction.
