It would be impractical to put your entire app in a single component. Instead, we can import components from other files and include them in our markup.
Add a <script>
tag to the top of App.svelte
that imports Nested.svelte
...
App.svelte
<script>
import Nested from './Nested.svelte';
</script>
...and include a <Nested />
component:
App.svelte
<p>This is a paragraph.</p>
<Nested />
Notice that even though Nested.svelte
has a <p>
element, the styles from App.svelte
don't leak in.
Component names are always capitalised, to distinguish them from HTML elements.
