💡 Hint

Common Mistakes

Using 'loading' or 'fallback' instead of 'ssr'.

Not disabling SSR causes the component to render on the server.

The ssr option set to false disables server-side rendering for the dynamic import, making it client-only.

Fix the error in the dynamic import to correctly load a client-only module.

💡 Hint

Common Mistakes

Setting ssr to true causes server rendering errors.

Using null or undefined does not disable SSR.

Setting ssr: false ensures the component loads only on the client side, fixing errors related to server rendering.

4fill in blank

hard

Fill both blanks to create a client-only component with a loading fallback.

NextJS

const ClientOnlyComp = dynamic(() => import('./ClientOnlyComp'), { [1]: false, [2]: () => <p>Loading...</p> });

Use ssr: false to disable server rendering and loading to show a loading message while the component loads.

5fill in blank

Fill all three blanks to import a client-only component with SSR disabled, a fallback UI, and suspense enabled.

Forgetting to disable SSR.

Using 'fallback' instead of 'loading'.
