queryOptions

Call Signature#

function queryOptions<TQueryFnData, TError, TData, TQueryKey>(options): QueryOptions<TQueryFnData, TError, TData, TQueryKey> & object & QueryKeyWithDataTag<TQueryKey, TQueryFnData, TError>;

Defined in: queryOptions.ts:90

You can generally pass everything to queryOptions that you can also pass to useQuery. These options can be shared across hooks and imperative APIs such as queryClient.query. options.queryKey is required and is the query key to generate options for.

This overload is selected when initialData is set, so the resulting data is never undefined.

Type Parameters#

TQueryFnData#

TQueryFnData = unknown

TError#

TError = Error

TData#

TData = TQueryFnData

TQueryKey#

TQueryKey extends readonly unknown[] = readonly unknown[]

Parameters#

options#

QueryOptions<TQueryFnData, TError, TData, TQueryKey> & object

The DefinedInitialDataOptions to use — everything you can pass to useQuery, with initialData set.

Returns#

QueryOptions<TQueryFnData, TError, TData, TQueryKey> & object & QueryKeyWithDataTag<TQueryKey, TQueryFnData, TError>

The same options object, typed so that queryKey carries the inferred data type.

See#

• useQuery to run a query with these options.

• The Query Options API for more on this pattern.

Example#

import { For } from 'solid-js'
import { queryOptions, useQuery } from '@tanstack/solid-query'

const postsOptions = queryOptions({
  queryKey: ['posts'],
  queryFn: fetchPosts,
  initialData: [],
})

function Posts() {
  // `postsQuery.data` is `Post[]`, never `undefined`, thanks to `initialData` — even if a refetch fails,
  // so the list stays visible alongside the error.
  const postsQuery = useQuery(() => postsOptions)

  return (
    <div>
      {postsQuery.isError ? <span>Error: {postsQuery.error.message}</span> : null}
      <ul>
        <For each={postsQuery.data}>{(post) => <li>{post.title}</li>}</For>
      </ul>
    </div>
  )
}

Call Signature#

function queryOptions<TQueryFnData, TError, TData, TQueryKey>(options): QueryOptions<TQueryFnData, TError, TData, TQueryKey> & object & QueryKeyWithDataTag<TQueryKey, TQueryFnData, TError>;

Defined in: queryOptions.ts:141

You can generally pass everything to queryOptions that you can also pass to useQuery. These options can be shared across hooks and imperative APIs such as queryClient.query. options.queryKey is required and is the query key to generate options for.

Type Parameters#

TQueryFnData#

TQueryFnData = unknown

TError#

TError = Error

TData#

TData = TQueryFnData

TQueryKey#

TQueryKey extends readonly unknown[] = readonly unknown[]

Parameters#

options#

QueryOptions<TQueryFnData, TError, TData, TQueryKey> & object

The UndefinedInitialDataOptions to use — everything you can pass to useQuery.

Returns#

QueryOptions<TQueryFnData, TError, TData, TQueryKey> & object & QueryKeyWithDataTag<TQueryKey, TQueryFnData, TError>

The same options object, typed so that queryKey carries the inferred data type.

See#

• useQuery to run a query with these options.

• The Query Options API for more on this pattern.

Example#

A parameterized factory, so the same options object can be reused per id:

import { Match, Switch } from 'solid-js'
import { queryOptions, useQuery } from '@tanstack/solid-query'

const postOptions = (id: string) =>
  queryOptions({
    queryKey: ['post', id],
    queryFn: () => fetchPost(id),
  })

function Post(props: { id: string }) {
  const postQuery = useQuery(() => postOptions(props.id))

  return (
    <Switch>
      <Match when={postQuery.isPending}>Loading...</Match>
      <Match when={postQuery.isError}>Error: {postQuery.error.message}</Match>
      <Match when={postQuery.isSuccess}>
        <h1>{postQuery.data.title}</h1>
      </Match>
    </Switch>
  )
}
