Lazy Query in RTK Query
Nadim Chowdhury
Posted on December 22, 2023
useLazyGetCustomerNameListQuery
is a hook generated by Redux Toolkit Query for the getCustomerNameList
query endpoint in your API. This hook provides a function that you can call to execute the query lazily. It's part of the useQuery
hooks provided by Redux Toolkit Query for making API requests.
Here's an explanation of the useLazyGetCustomerNameListQuery
hook:
- Usage:
const {
data, // The result of the query
error, // Any error that occurred during the query
isLoading, // Boolean indicating if the query is currently loading
refetch, // Function to manually trigger a refetch of the query
} = useLazyGetCustomerNameListQuery(queryParams);
-
Parameters:
-
queryParams
: An object containing parameters to be sent with the query. These parameters are used to customize the API request, and they depend on the specific requirements of your API endpoint.
-
-
Result:
-
data
: The result of the query if it's successful. -
error
: Any error that occurred during the query. -
isLoading
: A boolean indicating if the query is currently loading. -
refetch
: A function that you can call to manually trigger a refetch of the query.
-
Example:
const { data, error, isLoading, refetch } = useLazyGetCustomerNameListQuery({
// Query parameters specific to your API endpoint
// ...
});
if (isLoading) {
return <p>Loading...</p>;
}
if (error) {
return <p>Error: {error.message}</p>;
}
// Use the data obtained from the query
This hook follows the convention of other useQuery
hooks in Redux Toolkit Query. It abstracts away the complexity of handling API requests and provides a convenient way to interact with the results of those requests in your React components. The refetch
function allows you to manually trigger a re-execution of the query when needed.
