You need to declare the component in the parent module.

Are you building angular project?

Hills’s comment means you need to declare the components that you want to share in the corresponding modules, this is angular-specific setup.

Then import the “library module” in the module of the “consumer component”.

For example:

In library module:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
@NgModule({
  imports:      [ BrowserModule ],
  providers:    [ ],
  declarations: [ AppSlidesComponent, AppStartButtons ],
  exports:      [ AppSlidesComponent, AppStartButtons ],
})
export class AppLibModule { }

In the consumer module:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
@NgModule({
  imports:      [ BrowserModule, AppLibModule ],
  providers:    [ ],
  declarations: [ WelcomePageComponent ],
  exports:      [ WelcomePageComponent ],
})
export class WelcomeModule { }
