Class TJSFolderRolltable

Base class for Svelte components with some minor dev-enhancements. Used when dev=true.

Can be used to create strongly typed Svelte components.

Example:

You have component library on npm called component-library, from which you export a component called MyComponent. For Svelte+TypeScript users, you want to provide typings. Therefore you create a index.d.ts:

import { SvelteComponent } from "svelte";
export class MyComponent extends SvelteComponent<{foo: string}> {}
Copy

Typing this makes it possible for IDEs like VS Code with the Svelte extension to provide intellisense and to use the component like this in a Svelte file with TypeScript:

<script lang="ts">
	import { MyComponent } from "component-library";
</script>
<MyComponent foo={'bar'} />
Copy
