angular - Change default change detection strategy

Question

How to set the default change detection strategy to OnPush? Can it be set globally somehow?

I want to avoid having to adding this line to every component

@Component({
    ...
    changeDetection: ChangeDetectionStrategy.OnPush,
    ...
})

Answer 1

It is possible to set the change detection strategy to OnPush in the CLI so that newly generated components will have it set like that.

ng generate component test --changeDetection=OnPush

You can also set that value as default in your angular.json, so that you don't need to set the flag every time:

// angular.json
{
  //...
  "schematics": {
    "@schematics/angular": {
      "component": {
        "changeDetection": "OnPush"
      }
    }
  }
}
