ChangeDetectionStrategy • Angular

Use the CheckOnce strategy, meaning that automatic change detection is deactivated until reactivated by setting the strategy to Default (CheckAlways). Change detection can still be explicitly invoked. This strategy applies to all child directives and cannot be overridden.

NOTE: OnPush is enabled by default.

Use the Eager strategy, meaning that the component is checked eagerly when the change detection traversal reaches it, rather than only checking under certain circumstances (e.g. markForCheck, a signal in the template changed, etc).

@deprecated

Use Eager instead.

This value is equivalent to setting Eager and is due to be removed.
