useList
useList
is an extended version of TanStack Query's useQuery
. It supports all the features of useQuery
and adds some extra features.
It uses the
getList
method as the query function from thedataProvider
which is passed to<Refine>
.It uses a query key to cache the data. The query key is generated from the provided properties. You can see the query key by using the TanStack Query devtools.
When you need to fetch data according to sort, filter, pagination, etc. from a resource, you can use the useList
hook. It will return the data and some functions to control the query.
Basic Usage
Here is a basic example of how to use the useList
hook.
Pagination
The useList
hook supports the pagination feature. You can pass the pagination
property to enable pagination. To handle pagination, the useList
hook passes the pagination
property to the getList
method from the dataProvider
.
Dynamically changing the pagination
properties will trigger a new request.
Sorting
The useList
hook supports the sorting feature. You can pass the sort
property to enable sorting. To handle sorting, the useList
hook passes the sort
property to the getList
method from the dataProvider
.
Dynamically changing the sort
property will trigger a new request.
Filtering
The useList
hook supports the filtering feature. You can pass the filters
property to enable filtering. To handle filtering, the useList
hook passes the filters
property to the getList
method from the dataProvider
.
Dynamically changing the filters
property will trigger a new request.
Realtime Updates
This feature is only available if you use a Live Provider.
When the useList
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 →
Properties
resource
required
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.
useList({
resource: "categories",
});
dataProviderName
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.
useList({
dataProviderName: "second-data-provider",
});
config.filters
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 →
useList({
config: {
filters: [
{
field: "title",
operator: "contains",
value: "Foo",
},
],
},
});
config.sort
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 →
useList({
config: {
sort: [
{
field: "title",
order: "asc",
},
],
},
});
config.pagination
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.
current
You can pass the current
page number to the pagination
property.
useList({
config: {
pagination: {
current: 2,
},
},
});
pageSize
You can pass the pageSize
to the pagination
property.
useList({
config: {
pagination: {
pageSize: 20,
},
},
});
config.hasPagination
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.
useList({
config: {
hasPagination: false,
},
});
queryOptions
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 →
useList({
queryOptions: {
retry: 3,
},
});
metaData
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.
useList({
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(`${url}`, { headers });
return {
data,
};
},
//...
};
successNotification
NotificationProvider
is required for this prop to work.
After data is fetched successfully, useList
can call open
function from NotificationProvider
to show a success notification. With this prop, you can customize the success notification.
useList({
successNotification: (data, values, resource) => {
return {
message: `${data.title} Successfully fetched.`,
description: "Success with no errors",
type: "success",
};
},
});
errorNotification
NotificationProvider
is required for this prop to work.
After data fetching is failed, useList
will call open
function from NotificationProvider
to show an error notification. With this prop, you can customize the error notification.
useList({
errorNotification: (data, values, resource) => {
return {
message: `Something went wrong when getting ${data.id}`,
description: "Error",
type: "error",
};
},
});
liveMode
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 Live / Realtime page.
useList({
liveMode: "auto",
});
onLiveEvent
LiveProvider
is required for this prop to work.
The callback function is executed when new events from a subscription have arrived.
useList({
onLiveEvent: (event) => {
console.log(event);
},
});
liveParams
LiveProvider
is required for this prop to work.
Params to pass to liveProvider's subscribe method.
Return Values
Returns an object with TanStack Query's useQuery
return values.
