Function defineLazyModule

defineLazyModule<M>(
    key: string,
    loader: () => Promise<M>,
    options?: LazyModuleOptions,
): LazyModule<M>
Defines a module that is loaded on first use.
Type Parameters
- M
Parameters
- key: string
  Unique key, for example 'studio:sortDialog'.
- loader: () => Promise<M>
  Loads the module, typically () => import('./SortDialog'). It must resolve to the module itself: after a failed fetch, the module is imported again directly from the URL the browser reported.
- Optionaloptions: LazyModuleOptions
  Tier, prefetch, and retry options.
Returns LazyModule<M>
Remarks
Browsers remember a failed module fetch until the page reloads. When the browser's error names the module's URL, later attempts import that URL again under a new query string, so the module loads once the network is back. Where the error does not name it (Safari), a failed module loads again only after a reload.
Example
```
const SortDialog = defineLazyModule('studio:sortDialog', () => import('./SortDialog'), { tier: 'common' });
const { default: Dialog } = await SortDialog.load();
```
