Below is my folder structure.
app
- common
- header
header.component.css
header.component.html
header.component.ts
- footer
footer.component.css
footer.component.html
footer.component.ts
- index
index.component.css
index.component.ts
index.component.html
index.module.ts
- lessons
lesson1(another folder)
lesson2(folder)
lesson.module.ts
app.component.css
app.component.ts
app.component.html
app.module.ts
I have imported header & footer component, index.module, lesson.module in app.module and used
<app-header></app-header>
<app-navbar></app-navbar>
in index.component.html, lesson1.component.html, lesson2.component.html.
But I get 'app-header' is not a known element error. Can somebody help me to resolve this error?
It works well if I include header and footer components directly in index.module.ts
app.module.ts
