When should I use asyncData in Vue SSR?

You should use asyncData in Vue SSR when you need to fetch data before rendering a page, ensuring the data is available for the initial render.

Can you give me an example of how to implement asyncData?

Sure! In your Vue component, you can define an asyncData method that returns a promise. For example:

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

What are the benefits of using asyncData?

The benefits include improved SEO, faster initial page loads, and ensuring that the data is ready when the page is rendered.

Are there any downsides to using asyncData?

Yes, potential downsides include increased complexity in your components and the need to handle loading states and errors.
