Suspense

Solid Query can also be used with Solid's Suspense API's.

To do that you need to wrap your suspendable component with Suspense component provided by Solid

import { Suspense } from 'solid-js'
;<Suspense fallback={<LoadingSpinner />}>
  <SuspendableComponent />
</Suspense>

You can use async suspense function that is provided by solid-query.

import { useQuery } from '@tanstack/solid-query'

const todoFetcher = async () =>
  await fetch('https://jsonplaceholder.cypress.io/todos').then((response) =>
    response.json(),
  )

function SuspendableComponent() {
  const todosQuery = useQuery(() => ({
    queryKey: ['todos'],
    queryFn: todoFetcher,
  }))

  // Accessing todosQuery.data directly inside a <Suspense> boundary
  // automatically triggers suspension until data is ready
  return <div>Data: {JSON.stringify(todosQuery.data)}</div>
}

Fetch-on-render vs Render-as-you-fetch#

Out of the box, Solid Query in suspense mode works really well as a Fetch-on-render solution with no additional configuration. This means that when your components attempt to mount, they will trigger query fetching and suspend, but only once you have imported them and mounted them. If you want to take it to the next level and implement a Render-as-you-fetch model, we recommend implementing Prefetching on routing callbacks and/or user interactions events to start loading queries before they are mounted and hopefully even before you start importing or mounting their parent components.
