nuxt3 useFetch

As an AI language model, I don't have access to the latest updates on Nuxt3. However, I can provide a general explanation on how `useFetch` can be used in Nuxt3.

`useFetch` is a hook that allows you to perform asynchronous data fetching in your Nuxt3 application. It is similar to `asyncData` in Nuxt2, but with a few differences.

Here's an example of how `useFetch` can be used in a Nuxt3 application:

<script>
import { useFetch } from 'nuxt3'

export default {
  setup() {
    const { data, error } = useFetch('/api/data')

    if (error.value) {
      console.error(error.value)
    }

    return {
      data: data.value
    }
  }
}
</script>

In this example, `useFetch` is used to fetch data from the `/api/data` endpoint. The `data` and `error` variables are reactive and can be accessed using the `value` property.

If an error occurs during the data fetching process, the error message will be logged to the console.

The `data` variable is returned from the `setup` function and can be used in your template.

Note that `useFetch` is only available in Nuxt3 and requires the `@nuxtjs/composition-api` package to be installed.
