declare component in multiple modules
//Create a SharedModule:
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
@NgModule({
imports: [
CommonModule
],
declarations: [
SharedComponent
],
exports: [
SharedComponent
]
})
export class SharedModule {}
//and import it in the module you need:
@NgModule({
imports: [SharedModule]
})
//and in the appModule:
@NgModule({
imports: [ChildModule, SharedModule],...
})
