全局可用的定制管道
要使应用程序范围内的自定义管道可用,请在应用程序引导期间扩展 PLATFORM_PIPES。
import { bootstrap } from '@angular/platform-browser-dynamic';
import { provide, PLATFORM_PIPES } from '@angular/core';
import { AppComponent } from './app.component';
import { MyPipe } from './my.pipe'; // your custom pipe
bootstrap(AppComponent, [
provide(PLATFORM_PIPES, {
useValue: [
MyPipe
],
multi: true
})
]);
