Pagination#

RTK Query does not include any built-in pagination behavior. However, RTK Query does make it straightforward to integrate with a standard index-based pagination API. This is the most common form of pagination that you'll need to implement.

Pagination Recipes#

Setup an endpoint to accept a page arg#

src/app/services/posts.ts
import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query/react'
interface Post {
id: number
name: string
}
interface ListResponse<T> {
page: number
per_page: number
total: number
total_pages: number
data: T[]
}
export const api = createApi({
baseQuery: fetchBaseQuery({ baseUrl: '/' }),
endpoints: (builder) => ({
listPosts: builder.query<ListResponse<Post>, number | void>({
query: (page = 1) => `posts?page=${page}`,
}),
}),
})
export const { useListPostsQuery } = api

Trigger the next page by incrementing the page state variable#

src/features/posts/PostsManager.tsx
const PostList = () => {
const [page, setPage] = useState(1);
const { data: posts, isLoading, isFetching } = useListPostsQuery(page);
if (isLoading) {
return <div>Loading</div>;
}
if (!posts?.data) {
return <div>No posts :(</div>;
}
return (
<div>
{posts.data.map(({ id, title, status }) => (
<div key={id}>{title} - {status}</div>
))}
<button onClick={() => setPage(page - 1)} isLoading={isFetching}>
Previous
</button>
<button
onClick={() => setPage(page + 1)}
isLoading={isFetching}
>
Next
</button>
<div>
);
};

General Pagination Example#

In the following example, you'll see Loading on the initial query, but then as you move forward we'll use the next/previous buttons as a fetching indicator while any non-cached query is performed. When you go back, the cached data will be served instantaneously.
