Updates for all angular.io links to the new angular.dev domain. Additionally, adjustment to new resources where the equivalent does not exist on the new site (e.g. Tour of Heroes tutorial)
These async methods are a replacement for the Observable based `runSchematicAsync` and `runExternalSchematicAsync` methods.
DEPRECATED:
The Observable based `SchematicTestRunner.runSchematicAsync` and `SchematicTestRunner.runExternalSchematicAsync` method have been deprecated in favor of the Promise based `SchematicTestRunner.runSchematic` and `SchematicTestRunner.runExternalSchematic`.
All TypeScript files have been updated to pass the new eslint-based linting checks. eslint compatible disabling comments have also been added in place of the previous tslint comments.
Previously, `addSymbolToNgModuleMetadata()` assumed that the added
symbol would not span multiple lines. In most cases, the added symbol is
a single word, so this assumption was correct. In some cases, however,
we might want to add a mutli-line string, such as a static method of an
`@NgModule`:
```ts
imports: [
SomeModule.staticMethod({
prop1: 'val1',
prop2: 'val2'
})
]
```
This commit allows `addSymbolToNgModuleMetadata()` to correctly handle
multi-line strings by ensuring that added metadata symbols are always
put on a new line (even if the array is empty) and each line in the
string is indented as necessary.
Currently , the CLI generates :
```typescript
transform(value: any , args?: any)
```
With this commit , it generate :
```typescript
transform(value: any, ...args?: any[])
```
Which conforms to the official doc
Fixes#12602
