useDelete

useDelete is used when you want to delete a record. It is an extended version of TanStack Query's useMutation and not only supports all features of the mutation but also adds some extra features.

It uses the deleteOne method as the mutation function from the dataProvider which is passed to <Refine>.

Usage​

The useDelete hook returns many useful properties and methods. One of them is the mutate method which expects resource and id as parameters. These parameters will be passed to the deleteOne method from the dataProvider as parameters.

import { useDelete } from "@refinedev/core";

const { mutate } = useDelete();

mutate({
resource: "products",
id: 1,
});

Realtime Updates​

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

When the useDelete mutation runs successfully, it will call the publish method from liveProvider with some parameters such as channel, type etc. This is useful when you want to publish the changes to the subscribers on the client side.

Invalidating Queries​

When the useDelete mutation runs successfully, it will invalidate the following queries from the current resource: "list" and "many" by default. Which means that, if you use useList or useMany hooks on the same page, they will refetch the data after the mutation is completed. You can change this behavior by passing invalidates prop.

For more information, refer to the invalidation documentation β†’

Audit Logs​

This feature is only available if you use a Audit Log Provider.

When the useDelete mutation runs successfully, it will call the log method from auditLogProvider with some parameters such as resource, action, data, previousData etc. This is useful when you want to log the changes to the database.

Properties​

mutationOptions​

mutationOptions is used to pass options to the useMutation hook. It is useful when you want to pass additional options to the useMutation hook.

Refer to the useMutation documentation for more information β†’

useDelete({
mutationOptions: {
retry: 3,
},
});

mutationOptions does not support onSuccess and onError props because they override the default onSuccess and onError functions. If you want to use these props, you can pass them to mutate functions like this:

const { mutate } = useDelete();

mutate(
{
resource: "products",
id: 1,
},
{
onError: (error, variables, context) => {
// An error occurred!
},
onSuccess: (data, variables, context) => {
// Let's celebrate!
},
},
);

overtimeOptions​

If you want loading overtime for the request, you can pass the overtimeOptions prop to the this hook. It is useful when you want to show a loading indicator when the request takes too long. interval is the time interval in milliseconds. onInterval is the function that will be called on each interval.

Return overtime object from this hook. elapsedTime is the elapsed time in milliseconds. It becomes undefined when the request is completed.

const { overtime } = useDelete({
//...
overtimeOptions: {
interval: 1000,
onInterval(elapsedInterval) {
console.log(elapsedInterval);
},
},
});

console.log(overtime.elapsedTime); // undefined, 1000, 2000, 3000 4000, ...

// You can use it like this:
{
elapsedTime >= 4000 && <div>this takes a bit longer than expected</div>;
}

Mutation Parameters​

resource
required
​

This parameter will be passed to the deleteOne method from the dataProvider as a parameter. It is usually used as an API endpoint path but it all depends on how you handle the resource in the deleteOne method.

const { mutate } = useDelete();

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

For more information, refer to the creating a data provider tutorial β†’

If you have multiple resources with the same name, you can pass the identifier instead of the name of the resource. It will only be used as the main matching key for the resource, data provider methods will still work with the name of the resource defined in the <Refine/> component.

For more information, refer to the identifier of the <Refine/> component documentation β†’

id
required
​

This parameter will be passed to the deleteOne method from the dataProvider as a parameter. It is used to determine which record to delete.

const { mutate } = useDelete();

mutate({
id: 123,
});

mutationMode​

Mutation mode determines which mode the mutation runs with. Mutations can run under three different modes: pessimistic, optimistic, and undoable. The default mode is pessimistic. Each mode corresponds to a different type of user experience.

For more information, refer to the mutation mode documentation β†’

const { mutate } = useDelete();

mutate({
mutationMode: "undoable",
});

undoableTimeout​

When mutationMode is set to undoable, undoableTimeout is used to determine the duration to wait before executing the mutation. The default value is 5000 milliseconds.

const { mutate } = useDelete();

mutate({
mutationMode: "undoable",
undoableTimeout: 10000,
});

onCancel​

The onCancel property can be utilized when the mutationMode is set to "undoable". It provides a function that can be used to cancel the ongoing mutation.

By defining onCancel, undoable notification will not be shown automatically. This gives you the flexibility to handle the cancellation process in your own way, such as showing a custom notification or implementing any other desired behavior to allow users to cancel the mutation.

import { useRef } from "react";
import { useDelete } from "@refinedev/core";

const MyComponent = () => {
const { mutate } = useDelete();
const cancelRef = useRef<(() => void) | null>(null);

const deleteItem = () => {
mutate({
//...
mutationMode: "undoable",
onCancel: (cancelMutation) => {
cancelRef.current = cancelMutation;
},
});
};

const cancelDelete = () => {
cancelRef.current?.();
};

return (
<>
<button onClick={deleteItem}>Delete</button>
<button onClick={cancelDelete}>Cancel</button>
</>
);
};

successNotification​

NotificationProvider is required for this prop to work.

This prop allows you to customize the success notification that shows up when the data is fetched successfully and useDelete calls the open function from NotificationProvider:

const { mutate } = useDelete();

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

errorNotification​

NotificationProvider is required for this prop to work.

This prop allows you to customize the error notification that shows up when the data fetching fails and the useDelete calls the open function from NotificationProvider:

const { mutate } = useDelete();

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

meta​

meta is a special property that can be used to pass additional information to data provider methods for the following purposes:

  • Customizing the data provider methods for specific use cases.
  • Generating GraphQL queries using plain JavaScript Objects (JSON).

In the following example, we pass the headers property in the meta object to the deleteOne method. You can pass any properties to specifically handle the data provider methods with similar logic.

const { mutate } = useDelete();

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

const myDataProvider = {
//...
deleteOne: async ({
resource,
id,
meta,
}) => {
const headers = meta?.headers ?? {};
const url = `${apiUrl}/${resource}/${id}`;

//...
//...

const { data } = await httpClient.delete(url, undefined, { headers });

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

For more information, refer to the meta section of the General Concepts documentation→

dataProviderName​

This prop allows you to specify which dataProvider if you have more than one. Just pass it like in the example:

const { mutate } = useDelete();

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

invalidates​

invalidates is used to specify which queries should be invalidated after the mutation is completed.

By default, it invalidates the following queries from the current resource: "list" and "many". That means, if you use useList or useMany hooks on the same page, they will refetch the data after the mutation is completed.

const { mutate } = useDelete();

mutate({
invalidates: ["list", "many"],
});

Return Values​

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

For more information, refer to the useMutation documentation β†’

Additional Values​

overtime​

overtime object is returned from this hook. elapsedTime is the elapsed time in milliseconds. It becomes undefined when the request is completed.

const { overtime } = useDelete();

console.log(overtime.elapsedTime); // undefined, 1000, 2000, 3000 4000, ...
