useDelete

useDelete is a modified version of react-query's useMutation for delete mutations.

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

Features

Usage

Let's say that we have a resource named categories.

https://api.fake-rest.refine.dev/categories
{
[
{
id: 1,
title: "E-business",
},
{
id: 2,
title: "Virtual Invoice Avon",
},
];
}
import { useDelete } from "@pankod/refine";

const { mutate } = useDelete();

mutate({
resource: "categories",
id: "2",
});
tip

mutate can also accept lifecycle methods like onSuccess and onError. Refer to react-query docs for further information. β†’


After the mutation runs categories will be updated as below:

https://api.fake-rest.refine.dev/categories
{
[
{
id: 1,
title: "E-business",
},
];
}

note

Queries that use /categories endpoint will be automatically invalidated to show the updated data. For example, data returned from useList will be automatically updated.

tip

useDelete returns react-query's useMutation result. This result includes a lot of properties, one of which being mutate.

important

Variables passed to mutate must have these types.

{
id: string;
resource: string;
mutationMode?: MutationMode;
undoableTimeout?: number;
onCancel?: (cancelMutation: () => void) => void;
}

Mutation mode

Mutation mode determines the mode which the mutation runs with.

import { useDelete } from "@pankod/refine";

const { mutate } = useDelete();

mutate({
resource: "categories",
id: "2",
mutationMode: "optimistic",
});

Refer to mutation mode docs for further information. β†’

Creating a custom method for cancelling mutations

You can pass a custom cancel callback to useUpdate. This callback is triggered instead of the default one when undo button is clicked when mutationMode = "undoable".

caution

Default behaviour on undo action includes notifications. If a custom callback is passed this notification will not appear.

danger

Passed callback will receive a function that actually cancels the mutation. Don't forget to run this function to cancel the mutation on the undoable mode.

import { useDelete } from "@pankod/refine";

const customOnCancel = (cancelMutation: () => void) => {
cancelMutation();
// rest of custom cancel logic...
};

const { mutate } = useDelete();

mutate({
resource: "categories",
id: "1",
mutationMode: "undoable",
undoableTimeout: 7500,
onCancel: customOnCancel,
});

After 7.5 seconds the mutation will be executed. The mutation can be cancelled within that 7.5 seconds. If cancelled customOnCancel will be executed and the request will not be sent.

*: These props have default values in RefineContext and can also be set on <Refine> component. useDelete will use what is passed to <Refine> as default but a local value will override it.
