* Base class to create strongly typed Svelte components.
* This only exists for typing purposes and should be used in `.d.ts` files.
*
* ### 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`:
* ```ts
* import { SvelteComponentTyped } from "svelte";
* export class MyComponent extends SvelteComponentTyped<{foo: string}> {}
* ```
* 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:
* ```svelte
*
*
* ```
*
* #### Why not make this part of `SvelteComponent(Dev)`?
* Because
* ```ts
* class ASubclassOfSvelteComponent extends SvelteComponent<{foo: string}> {}
* const component: typeof SvelteComponent = ASubclassOfSvelteComponent;
* ```
* will throw a type error, so we need to separate the more strictly typed class.
