 Provide a custom path for the ESM loader directory, containing files you can import in an initiation script within your application to register all your components for lazy loading. Read more about the loader directory in the [section below](#loader).

+
+```js
+import { defineCustomElements } from 'stencil-library/dist/loader'
+```

+
+```js
+import { defineCustomElements } from 'stencil-library/loader'
+```
