<InfiniteListBase>

The <InfiniteListBase> component is a headless version of the infinite list functionality. It fetches records from the data provider and provides infinite scrolling capabilities through a ListContext, but doesn’t render any UI by itself. This allows you to create fully custom list layouts with infinite loading.

<InfiniteListBase> fetches the list of records from the data provider using the useInfiniteListController hook and provides the data through a context. You have complete control over how to render the list of records.

Usage

Here is the minimal code necessary to display a list of books with infinite scroll:

// in src/books.js
import { InfiniteListBase, useListContext, useInfinitePaginationContext } from 'ra-core';

const BookTable = () => {
    const { data, isPending } = useListContext();

    if (isPending) {
        return <div>Loading...</div>;
    }

    return (
        <table>
            <thead>
                <tr>
                    <th>ID</th>
                    <th>Title</th>
                    <th>Author</th>
                </tr>
            </thead>
            <tbody>
                {data.map(book => (
                    <tr key={book.id}>
                        <td>{book.id}</td>
                        <td>{book.title}</td>
                        <td>{book.author}</td>
                    </tr>
                ))}
            </tbody>
        </table>
    );
};

const InfinitePagination = () => {
    const { hasNextPage, fetchNextPage, isFetchingNextPage } = useInfinitePaginationContext();

    if (!hasNextPage) {
        return null;
    }

    return (
        <div style={{ textAlign: 'center', margin: '1rem' }}>
            <button
                disabled={isFetchingNextPage}
                onClick={() => fetchNextPage()}
            >
                {isFetchingNextPage ? 'Loading...' : 'Load more'}
            </button>
        </div>
    );
};

export const BookList = () => (
    <InfiniteListBase>
        <div>
            <h1>Books</h1>
            <BookTable />
            <InfinitePagination />
        </div>
    </InfiniteListBase>
);

// in src/App.js
import { CoreAdmin, Resource } from 'ra-core';
import jsonServerProvider from 'ra-data-json-server';

import { BookList } from './books';

const App = () => (
    <CoreAdmin dataProvider={jsonServerProvider('https://jsonplaceholder.typicode.com')}>
        <Resource name="books" list={BookList} />
    </CoreAdmin>
);

export default App;

That’s enough to display a basic list with infinite scroll functionality. When users click the “Load more” button, additional records are fetched and appended to the list.

Props

<InfiniteListBase> accepts the same props as <ListBase>, but configured for infinite loading:

Prop	Required	Type	Default	Description
`children`	Required if no render	`ReactNode`	-	The component to use to render the list of records.
`render`	Required if no children	`ReactNode`	-	A function that render the list of records, receives the list context as argument.
`debounce`	Optional	`number`	`500`	The debounce delay in milliseconds to apply when users change the sort or filter parameters.
`disable Authentication`	Optional	`boolean`	`false`	Set to `true` to disable the authentication check.
`disable SyncWithLocation`	Optional	`boolean`	`false`	Set to `true` to disable the synchronization of the list parameters with the URL.
`exporter`	Optional	`function`	-	The function to call to export the list.
`filter`	Optional	`object`	-	The permanent filter values.
`filter DefaultValues`	Optional	`object`	-	The default filter values.
`perPage`	Optional	`number`	`10`	The number of records to fetch per page.
`queryOptions`	Optional	`object`	-	The options to pass to the `useQuery` hook.
`resource`	Optional	`string`	-	The resource name, e.g. `posts`.
`sort`	Optional	`object`	-	The initial sort parameters.
`storeKey`	Optional	`string`	-	The key to use to store the current filter & sort.

Check the <ListBase> component for details about each prop.

Pagination

Since <InfiniteListBase> is headless, you need to implement your own pagination component. You can use the useInfinitePaginationContext hook to get the pagination state and callbacks.

load more button

For example, here is a custom infinite pagination component displaying a “Load More” button at the bottom of the list:

import { InfiniteListBase, useInfinitePaginationContext, useListContext } from 'ra-core';

const LoadMore = () => {
    const {
        hasNextPage,
        fetchNextPage,
        isFetchingNextPage,
    } = useInfinitePaginationContext();

    return hasNextPage ? (
        <div style={{ marginTop: '1rem', textAlign: "center" }}>
            <button
                disabled={isFetchingNextPage}
                onClick={() => fetchNextPage()}
            >
                Load more
            </button>
        </div>
    ) : null;
};

const BookTable = () => {
    const { data } = useListContext();

    return (
        <table>
            <thead>
                <tr>
                    <th>ID</th>
                    <th>Title</th>
                    <th>Author</th>
                </tr>
            </thead>
            <tbody>
                {data.map(book => (
                    <tr key={book.id}>
                        <td>{book.id}</td>
                        <td>{book.title}</td>
                        <td>{book.author}</td>
                    </tr>
                ))}
            </tbody>
        </table>
    );
};

export const BookList = () => (
    <InfiniteListBase>
        <div>
            <BookTable />
            <LoadMore />
        </div>
    </InfiniteListBase>
);

Showing The Record Count

You can use useListContext to access the total property of the list, and render the total number of results in a sticky footer:

Infinite list with total number of results

import { useListContext, useInfinitePaginationContext, InfiniteListBase } from 'ra-core';

const CustomPagination = () => {
    const { total } = useListContext();
    const { hasNextPage, fetchNextPage, isFetchingNextPage } = useInfinitePaginationContext();

    return (
        <div>
            {hasNextPage && (
                <div style={{ textAlign: 'center', margin: '1rem' }}>
                    <button
                        disabled={isFetchingNextPage}
                        onClick={() => fetchNextPage()}
                    >
                        {isFetchingNextPage ? 'Loading...' : 'Load more'}
                    </button>
                </div>
            )}
            {total > 0 && (
                <div style={{
                    position: "sticky",
                    bottom: 0,
                    textAlign: "center",
                    backgroundColor: 'white',
                    border: '1px solid #ccc',
                    padding: '0.5rem',
                    margin: '0.5rem',
                    borderRadius: '4px'
                }}>
                    <span>{total} results</span>
                </div>
            )}
        </div>
    );
};

export const BookList = () => (
    <InfiniteListBase>
        <div>
            {/* Your list content here */}
            <CustomPagination />
        </div>
    </InfiniteListBase>
);

Controlled Mode

<InfiniteListBase> deduces the resource and the list parameters from the URL. This is fine for a page showing a single list of records, but if you need to display more than one list in a page, you probably want to define the list parameters yourself.

In that case, use the resource, sort, and filter props to set the list parameters.

import { InfiniteListBase, useListContext, useInfinitePaginationContext } from 'ra-core';

const SimpleList = ({ primaryText, secondaryText, tertiaryText }) => {
    const { data } = useListContext();

    return (
        <div>
            {data.map(item => (
                <div key={item.id} style={{
                    padding: '1rem',
                    borderBottom: '1px solid #eee'
                }}>
                    <div style={{ fontWeight: 'bold' }}>
                        {primaryText(item)}
                    </div>
                    {secondaryText && (
                        <div style={{ color: '#666' }}>
                            {secondaryText(item)}
                        </div>
                    )}
                    {tertiaryText && (
                        <div style={{ fontSize: '0.875rem', color: '#999' }}>
                            {tertiaryText(item)}
                        </div>
                    )}
                </div>
            ))}
        </div>
    );
};

const InfinitePagination = () => {
    const { hasNextPage, fetchNextPage, isFetchingNextPage } = useInfinitePaginationContext();

    return hasNextPage ? (
        <div style={{ textAlign: 'center', margin: '1rem' }}>
            <button
                disabled={isFetchingNextPage}
                onClick={() => fetchNextPage()}
            >
                {isFetchingNextPage ? 'Loading...' : 'Load more'}
            </button>
        </div>
    ) : null;
};

const Dashboard = () => (
    <div style={{ padding: '2rem' }}>
        <h2>Latest posts</h2>
        <InfiniteListBase
            resource="posts"
            sort={{ field: 'published_at', order: 'DESC' }}
            filter={{ is_published: true }}
            disableSyncWithLocation
        >
            <SimpleList
                primaryText={record => record.title}
                secondaryText={record => `${record.views} views`}
            />
            <InfinitePagination />
        </InfiniteListBase>

        <h2>Latest comments</h2>
        <InfiniteListBase
            resource="comments"
            sort={{ field: 'published_at', order: 'DESC' }}
            perPage={10}
            disableSyncWithLocation
        >
            <SimpleList
                primaryText={record => record.author.name}
                secondaryText={record => record.body}
                tertiaryText={record => new Date(record.published_at).toLocaleDateString()}
            />
            <InfinitePagination />
        </InfiniteListBase>
    </div>
)

Using the Hook Directly

If you don’t need the ListContext, you can use the useInfiniteListController hook directly, which does the same data fetching as <InfiniteListBase> but lets you render the content however you want.

import { useInfiniteListController } from 'ra-core';

const ProductList = () => {
    const { isPending, data, hasNextPage, fetchNextPage, isFetchingNextPage } = useInfiniteListController({
        resource: 'products'
    });

    return (
        <div style={{ padding: '2rem' }}>
            <h1>All products</h1>
            {!isPending && (
                <div style={{ display: 'flex', flexDirection: 'column', gap: '1rem' }}>
                    {data.map(product => (
                        <div key={product.id} style={{
                            border: '1px solid #ccc',
                            padding: '1rem',
                            borderRadius: '4px'
                        }}>
                            <h3>{product.name}</h3>
                        </div>
                    ))}
                </div>
            )}
            {hasNextPage && (
                <div style={{ textAlign: 'center', marginTop: '2rem' }}>
                    <button
                        disabled={isFetchingNextPage}
                        onClick={() => fetchNextPage()}
                    >
                        {isFetchingNextPage ? 'Loading...' : 'Load more'}
                    </button>
                </div>
            )}
        </div>
    );
};

useInfiniteListController returns callbacks to sort, filter, and paginate the list, so you can build a complete infinite list page.

Security

The <InfiniteListBase> component requires authentication and will redirect anonymous users to the login page. If you want to allow anonymous access, use the disableAuthentication prop.

If your authProvider implements Access Control, <InfiniteListBase> will only render if the user has the “list” access to the related resource.

For instance, for the <PostList> page below:

import { InfiniteListBase, useListContext } from 'ra-core';

const PostTable = () => {
    const { data } = useListContext();

    return (
        <table>
            <thead>
                <tr>
                    <th>Title</th>
                    <th>Author</th>
                    <th>Published At</th>
                </tr>
            </thead>
            <tbody>
                {data.map(post => (
                    <tr key={post.id}>
                        <td>{post.title}</td>
                        <td>{post.author}</td>
                        <td>{post.published_at}</td>
                    </tr>
                ))}
            </tbody>
        </table>
    );
};

// Resource name is "posts"
const PostList = () => (
    <InfiniteListBase>
        <PostTable />
    </InfiniteListBase>
);

<InfiniteListBase> will call authProvider.canAccess() using the following parameters:

{ action: "list", resource: "posts" }

Users without access will be redirected to the Access Denied page.

Note: Access control is disabled when you use the disableAuthentication prop.
