How does Nuxt.js handle async data in SSR?

How does Nuxt.js handle async data in server-side rendering?

Nuxt.js uses the asyncData method to fetch data asynchronously before rendering a page. This allows the server to send fully rendered pages to the client.

Can you give me an example of using asyncData in a Nuxt.js page?

Sure! In a Nuxt.js page component, you can define an asyncData method like this:

export default {
  async asyncData({ params }) {
    const data = await fetch(`https://api.example.com/items/${params.id}`);
    return { item: await data.json() };
  }
}

What happens if the asyncData call fails?

If the asyncData call fails, Nuxt.js will handle the error gracefully. You can use a try-catch block to manage errors and return a specific error state.

Is asyncData only for server-side rendering?

No, asyncData is also called when navigating to a page client-side, ensuring that data is always up-to-date.
