I can't figure out why the header isn't showing up in my basic Angular application

As a newcomer to Angular, I have been working on creating a simple application for hands-on learning. I decided to utilize the shared.module.ts file to handle my header and then imported it into my app.module.ts. However, after running the application, I noticed that the

<app-header></app-header>
component was not rendering as expected. Below is the code snippet in question - Can anyone pinpoint what went wrong? I am confident that I followed the correct procedures for exporting/importing/declaring components.

shared.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { HeaderComponent } from './components/header/header.component';



@NgModule({
  declarations: [HeaderComponent],
  imports: [
    CommonModule
  ],
  exports: [
    HeaderComponent // exporting header component from shared module here
  ]
})
export class SharedModule { }

app.module.ts

//predefined modules
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

//application modules
import { AppRoutingModule } from './app-routing.module';
import {BlogModule} from './blog/blog.module';
import { SharedModule} from './shared/shared.module'

//components
import { AppComponent } from './app.component';
import { DashboardComponent } from './dashboard/dashboard.component';

@NgModule({
  declarations: [
    AppComponent,
    DashboardComponent //declaring the dashboard component
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    BlogModule,
    SharedModule //importing the shared module here
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

dashboard.component.html

Hello, Header is below
<app-header></app-header>

What I see on the browser:

https://i.sstatic.net/rQpa4.png

Upon observing the webpage, it is evident that the header fails to load, even though there are no errors showing up in the browser console.

Answer №1

Incorporating the Dashboard component into the App module and importing the Shared module is a good start. However, it seems that you are using the Header component within the Dashboard component instead of the App Component, which may cause issues. To resolve this issue, consider creating a separate module specifically for the Dashboard component and importing the Shared module there to properly utilize the Header component. Alternatively, you can directly use the Header component in the app.component.html file.
