更改默认更改检测策略 [英] Change default change detection strategy

问题描述

如何将默认更改检测策略设置为 OnPush ？可以以某种方式在全局设置它吗？

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

我要避免不必将此行添加到每个组件中

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

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

推荐答案

更改检测策略只能针对每个组件或指令定义，而不能全局定义。

The change detection strategy can only be defined per component or directive not globally.

使用自定义装饰器，因为即将发布的脱机模板编译器将不支持它。

Using a custom decorator is discouraged because it will not be supported by the upcoming offline template compiler.
