useInfiniteList

Here is a basic example of how to use the useInfiniteList hook.

import React from "react";
import { useInfiniteList } from "@pankod/refine-core";

const PostList = () => {
    const {
        data,
        isError,
        isLoading,
        hasNextPage,
        fetchNextPage,
        isFetchingNextPage,
    } = useInfiniteList({
        resource: "categories",
        config: {
            pagination: {
                pageSize: 4
            }
        }
    });

    if (isLoading) {
        return <p>Loading</p>;
    }
    if (isError) {
        return <p>Something went wrong</p>;
    }

    const allPages = [].concat(...(data?.pages ?? []).map((page) => page.data));

    return (
        <div>
            <ul>
                {allPages.map(({ id, title }) => (
                    <li key={id}>
                        {id}.{title}
                    </li>
                ))}
            </ul>
            {
                hasNextPage && (
                    <button
                        onClick={() => fetchNextPage()}
                        disabled={isFetchingNextPage}
                    >
                        {isFetchingNextPage ? "Loading more..." : "Load More" }
                    </button>
                )
            }
        </div>
    );
}

useInfiniteList hook supports pagination properties just like useList. To handle pagination, the useInfiniteList hook passes the pagination property to the getList method from the dataProvider.

Dynamically changing the pagination properties will trigger a new request. Also, the fetchNextPage method will increase the pagination.current property by one and trigger a new request.

import { useInfiniteList } from "@pankod/refine-core";

const postListQueryResult = useInfiniteList({
  resource: "posts",
  config: {
    pagination: { current: 3, pageSize: 8 },
  },
});

The useInfiniteList hook supports the sorting feature. You can pass the sort property to enable sorting. To handle sorting, the useInfiniteList hook passes the sort property to the getList method from the dataProvider.

Dynamically changing the sort property will trigger a new request.

import { useState } from "react";
import { useInfiniteList, HttpError } from "@pankod/refine-core";

interface IProduct {
    id: number;
    name: string;
    material: string;
}

const ProductList: React.FC = () => {
    const [order, setOrder] = useState<"asc" | "desc">("asc");

    const {
        data,
        isLoading,
        isError,
        hasNextPage,
        fetchNextPage,
        isFetchingNextPage
    } = useInfiniteList<IProduct, HttpError>({
        resource: "products",
        config: {
            sort: [
                {
                    field: "name",
                    order,
                },
            ],
        },
    });

    if (isLoading) {
        return <p>Loading</p>;
    }
    if (isError) {
        return <p>Something went wrong</p>;
    }

    const allPages = [].concat(...(data?.pages ?? []).map((page) => page.data));

    return (
        <div>
            <button
                onClick={() =>
                    setOrder((prev) => (prev === "asc" ? "desc" : "asc"))
                }
            >
                toggle sort
            </button>

            <ul>
                {allPages.map((product) => (
                    <li key={product.id}>
                        {product.name} - ({product.material})
                    </li>
                ))}
            </ul>

            {
                hasNextPage && (
                    <button
                        onClick={() => fetchNextPage()}
                        disabled={isFetchingNextPage}
                    >
                        {isFetchingNextPage ? "Loading more..." : "Load More" }
                    </button>
                )
            }
        </div>
    );
};

The useInfiniteList hook supports the filtering feature. You can pass the filters property to enable filtering. To handle filtering, the useInfiniteList hook passes the filters property to the getList method from the dataProvider.

Dynamically changing the filters property will trigger a new request.

import { useState } from "react";
import { useInfiniteList, HttpError } from "@pankod/refine-core";

interface IProduct {
    id: number;
    name: string;
    material: string;
}

const ProductList: React.FC = () => {
    const [value, setValue] = useState("Cotton");

    const {
        data,
        isLoading,
        isError,
        hasNextPage,
        fetchNextPage,
        isFetchingNextPage
    } = useInfiniteList<IProduct, HttpError>({
        resource: "products",
        config: {
            filters: [
                {
                    field: "material",
                    operator: "eq",
                    value,
                },
            ],
        },
    });

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

    if (isError) {
        return <div>Something went wrong!</div>;
    }

    const allPages = [].concat(...(data?.pages ?? []).map((page) => page.data));

    return (
        <div>
            <span> material: </span>
            <select value={value} onChange={(e) => setValue(e.target.value)}>
                {["Cotton", "Bronze", "Plastic"].map((material) => (
                    <option key={material} value={material}>
                        {material}
                    </option>
                ))}
            </select>

            <ul>
                {allPages.map((product) => (
                    <li key={product.id}>
                        {product.name} - ({product.material})
                    </li>
                ))}
            </ul>

            {
                hasNextPage && (
                    <button
                        onClick={() => fetchNextPage()}
                        disabled={isFetchingNextPage}
                    >
                        {isFetchingNextPage ? "Loading more..." : "Load More" }
                    </button>
                )
            }
        </div>
    );
};

This feature is only available if you use a Live Provider.

When the useInfiniteList hook is mounted, it will call the subscribe method from the liveProvider with some parameters such as channel, resource etc. It is useful when you want to subscribe to live updates.

Refer to the liveProvider documentation for more information →

It will be passed to the getList method from the dataProvider as a parameter. The parameter is usually used as an API endpoint path. It all depends on how to handle the resource in the getList method. See the creating a data provider section for an example of how resources are handled.

useInfiniteList({
  resource: "categories",
});

If there is more than one dataProvider, you can specify which one to use by passing the dataProviderName prop. It is useful when you have a different data provider for different resources.

useInfiniteList({
  dataProviderName: "second-data-provider",
});

filters will be passed to the getList method from the dataProvider as a parameter. It is used to send filter query parameters to the API.

Refer to the CrudFilters interface for more information →

useInfiniteList({
  config: {
    filters: [
      {
        field: "title",
        operator: "contains",
        value: "Foo",
      },
    ],
  },
});

sort will be passed to the getList method from the dataProvider as a parameter. It is used to send sort query parameters to the API.

Refer to the CrudSorting interface for more information →

useInfiniteList({
  config: {
    sort: [
      {
        field: "title",
        order: "asc",
      },
    ],
  },
});

pagination will be passed to the getList method from the dataProvider as a parameter. It is used to send pagination query parameters to the API.

You can pass the current page number to the pagination property.

useInfiniteList({
  config: {
    pagination: {
      current: 2,
    },
  },
});

You can pass the pageSize to the pagination property.

useInfiniteList({
  config: {
    pagination: {
      pageSize: 20,
    },
  },
});

hasPagination will be passed to the getList method from the dataProvider as a parameter. It is used to determine whether to use server-side pagination or not.

useInfiniteList({
  config: {
    hasPagination: false,
  },
});

queryOptions is used to pass additional options to the useQuery hook. It is useful when you want to pass additional options to the useQuery hook.

Refer to the useQuery documentation for more information →

useInfiniteList({
  queryOptions: {
    retry: 3,
  },
});

metaData is used following two purposes:

• To pass additional information to data provider methods.
• Generate GraphQL queries using plain JavaScript Objects (JSON). Please refer GraphQL for more information.

In the following example, we pass the headers property in the metaData object to the create method. With similar logic, you can pass any properties to specifically handle the data provider methods.

useInfiniteList({
  metaData: {
    headers: { "x-meta-data": "true" },
  },
});

const myDataProvider = {
  //...
  getList: async ({
    resource,
    pagination,
    hasPagination,
    sort,
    filters,
    metaData,
  }) => {
    const headers = metaData?.headers ?? {};
    const url = `${apiUrl}/${resource}`;

    //...
    //...

    const { data } = await httpClient.get(`${url}`, { headers });

    return {
      data,
    };
  },
  //...
};

NotificationProvider is required for this prop to work.

After data is fetched successfully, useInfiniteList can call open function from NotificationProvider to show a success notification. With this prop, you can customize the success notification.

useInfiniteList({
  successNotification: (data, values, resource) => {
    return {
      message: `${data.title} Successfully fetched.`,
      description: "Success with no errors",
      type: "success",
    };
  },
});

NotificationProvider is required for this prop to work.

After data fetching is failed, useInfiniteList will call open function from NotificationProvider to show an error notification. With this prop, you can customize the error notification.

useInfiniteList({
  errorNotification: (data, values, resource) => {
    return {
      message: `Something went wrong when getting ${data.id}`,
      description: "Error",
      type: "error",
    };
  },
});

LiveProvider is required for this prop to work.

Determines whether to update data automatically ("auto") or not ("manual") if a related live event is received. It can be used to update and show data in Realtime throughout your app. For more information about live mode, please check the Live / Realtime page.

useInfiniteList({
  liveMode: "auto",
});

LiveProvider is required for this prop to work.

The callback function is executed when new events from a subscription have arrived.

useInfiniteList({
  onLiveEvent: (event) => {
    console.log(event);
  },
});

LiveProvider is required for this prop to work.

Params to pass to liveProvider's subscribe method.

Returns an object with TanStack Query's useInfiniteQuery return values.

Refer to the useInfiniteQuery documentation for more information →

Some APIs use the cursor-pagination method for its benefits. This method uses a cursor object to determine the next set of data. The cursor can be a number or a string and is passed to the API as a query parameter.

Preparing the data provider:

Consumes data from data provider useInfiniteList with the getList method. First of all, we need to make this method in the data provider convenient for this API. The cursor data is kept in pagination and should be set to 0 by default.

getList: async ({ resource, pagination }) => {
    const { current } = pagination;
    const { data } = await axios.get(
        `https://api.fake-rest.refine.dev/${resource}?cursor=${current || 0}`,
    );

    return {
        data: data[resource],
        total: 0,
    };
},

After this process, we successfully retrieved the first page of data. Let's fill the cursor object for the next page.

getList: async ({ resource, pagination }) => {
    const { current } = pagination;
    const { data } = await axios.get(
        `https://api.fake-rest.refine.dev/${resource}?cursor=${current || 0}`,
    );

    return {
        data: data[resource],
        total: 0,
        cursor: {
            next: data.cursor.next,
            prev: data.cursor.prev,
        },
    };
},

By default, refine expects you to return the cursor object, but is not required. This is because some APIs don't work that way. To fix this problem you need to override the getNextPageParam method and return the next cursor.

import { useInfiniteList } from "@pankod/refine-core";

const {
  data,
  error,
  hasNextPage,
  isLoading,
  fetchNextPage,
  isFetchingNextPage,
} = useInfiniteList({
  resource: "posts",
  queryOptions: {
    getNextPageParam: (lastPage, allPages) => {
      // return the last post's id
      const { data } = lastPage;
      const lastPost = data[data.length - 1];
      return lastPost.id;
    },
  },
});
