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 Vue
import { Suspense } from 'solid-js'
;<Suspense fallback={<LoadingSpinner />}>
<SuspendableComponent />
</Suspense>
import { Suspense } from 'solid-js'
;<Suspense fallback={<LoadingSpinner />}>
<SuspendableComponent />
</Suspense>
You can use async suspense function that is provided by solid-query.
<script>
import { defineComponent } from 'vue'
import { useQuery } from '@tanstack/solid-query'
const todoFetcher = async () =>
await fetch('https://jsonplaceholder.cypress.io/todos').then((response) =>
response.json(),
)
export default defineComponent({
name: 'SuspendableComponent',
async setup() {
const { data, suspense } = useQuery(() => ['todos'], todoFetcher)
await suspense()
return { data }
},
})
</script>
<script>
import { defineComponent } from 'vue'
import { useQuery } from '@tanstack/solid-query'
const todoFetcher = async () =>
await fetch('https://jsonplaceholder.cypress.io/todos').then((response) =>
response.json(),
)
export default defineComponent({
name: 'SuspendableComponent',
async setup() {
const { data, suspense } = useQuery(() => ['todos'], todoFetcher)
await suspense()
return { data }
},
})
</script>
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.
