Vue: Async Data vs Sync Data

What is the difference between async data and sync data in Vue?

In Vue, async data is fetched asynchronously, allowing the app to remain responsive, while sync data is loaded synchronously, blocking the UI until the data is available.

Can you give me an example of how to implement async data in a Vue component?

Sure! You can use the asyncData method in a Vue component to fetch data before rendering. For example:

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

What are the advantages of using async data?

The main advantages of async data include improved user experience, as it prevents the UI from freezing, and better performance, as data can be loaded in parallel with other operations.

Are there any downsides to using async data?

Yes, async data can introduce complexity in error handling and state management, and it may lead to race conditions if not managed properly.
