Angular v9 schematics should print out a link to the migration guide associated with each schematic. This way, users have an easy way to find more information about the automatic code transformations they will see with `ng update`. PR Close #33258 |

Renderer -> Renderer2 migration
Automatically migrates from Renderer to Renderer2 by changing method calls, renaming imports
and renaming types. Tries to either map method calls directly from one renderer to the other, or
if that's not possible, inserts custom helper functions at the bottom of the file.
Before
import { Renderer, ElementRef } from '@angular/core';
@Component({})
export class MyComponent {
constructor(private _renderer: Renderer, private _elementRef: ElementRef) {}
changeColor() {
this._renderer.setElementStyle(this._element.nativeElement, 'color', 'purple');
}
}
After
import { Renderer2, ElementRef } from '@angular/core';
@Component({})
export class MyComponent {
constructor(private _renderer: Renderer2, private _elementRef: ElementRef) {}
changeColor() {
this._renderer.setStyle(this._element.nativeElement, 'color', 'purple');
}
}
