`useRefresh`

This hook returns a function that forces a refetch of all the active queries, and a rerender of the current view when the data has changed.

import { useRefresh } from 'react-admin';
const RefreshButton = () => {
 const refresh = useRefresh();
 const handleClick = () => {
 refresh();
 }
 return <button onClick={handleClick}>Refresh</button>;
};

It is common to use it after a mutation, e.g. after deleting a record.

import * as React from 'react';
import { useDelete, useNotify, useRefresh, useRecordContext, Button } from 'react-admin';
const DeleteCommentButton = () => {
 const refresh = useRefresh();
 const record = useRecordContext();
 const notify = useNotify();
 const [deleteOne, { isPending }] = useDelete(
 'comments',
 { id: record.id },
 {
 onSuccess: (data) => {
 refresh();
 notify('Comment deleted');
 },
 onError: (error) => {
 notify(`Comment deletion error: ${error.message}`, { type: 'error' });
 },
 }
 );
 
 return <Button label="delete" onClick={() => deleteOne()} disabled={isPending} />;
};
