useForm

Install the @refinedev/react-hook-form library.

npm i @refinedev/react-hook-form

pnpm add @refinedev/react-hook-form

yarn add @refinedev/react-hook-form

For more detailed usage examples please refer to the React Hook Form documentation.

We'll show the basic usage of useForm by adding an editing form.

import { useSelect } from "@refinedev/core";
import { useForm } from "@refinedev/react-hook-form";

export const PostEdit: React.FC = () => {
  const {
    refineCore: { onFinish, formLoading, query },
    register,
    handleSubmit,
    resetField,
    formState: { errors },
  } = useForm();

  const { options } = useSelect({
    resource: "categories",
    defaultValue: query?.data?.data.category.id,
  });

  useEffect(() => {
    resetField("category.id");
  }, [options]);

  return (
    <form onSubmit={handleSubmit(onFinish)}>
      <label>Title: </label>
      <input {...register("title", { required: true })} />
      {errors.title && <span>This field is required</span>}
      <br />
      <label>Status: </label>
      <select {...register("status")}>
        <option value="published">published</option>
        <option value="draft">draft</option>
        <option value="rejected">rejected</option>
      </select>
      <br />
      <label>Category: </label>
      <select
        {...register("category.id", {
          required: true,
        })}
        defaultValue={query?.data?.data.category.id}
      >
        {options?.map((category) => (
          <option key={category.value} value={category.value}>
            {category.label}
          </option>
        ))}
      </select>
      {errors.category && <span>This field is required</span>}
      <br />
      <label>Content: </label>
      <br />
      <textarea
        {...register("content", { required: true })}
        rows={10}
        cols={50}
      />
      {errors.content && <span>This field is required</span>}
      <br />

      {query?.data?.data?.thumbnail && (
        <>
          <br />
          <label>Image: </label>
          <br />

          <img src={query?.data?.data?.thumbnail} width={200} height={200} />
          <br />
          <br />
        </>
      )}

      <input type="submit" value="Submit" />
      {formLoading && <p>Loading</p>}
    </form>
  );
};

If you want to show a form in a modal or drawer where necessary route params might not be there you can use the useModalForm.

useForm can handle edit, create and clone actions.

By default, it determines the action from route. The action is inferred by matching the resource's action path with the current route.

It can be overridden by passing the action prop where it isn't possible to determine the action from the route (e.g. when using form in a modal or using a custom route).

import { useForm } from "@refinedev/react-hook-form";

const PostCreatePage: React.FC = () => {
  const {
    refineCore: { onFinish, formLoading },
    register,
    handleSubmit,
    formState: { errors },
  } = useForm();

  return (
    <form onSubmit={handleSubmit(onFinish)}>
      <label>Title: </label>
      <input {...register("title", { required: true })} />
      {errors.title && <span>This field is required</span>}
      <br />
      <label>Status: </label>
      <select {...register("status")}>
        <option value="published">published</option>
        <option value="draft">draft</option>
        <option value="rejected">rejected</option>
      </select>
      <br />
      <label>Content: </label>
      <br />
      <textarea
        {...register("content", { required: true })}
        rows={10}
        cols={50}
      />
      {errors.content && <span>This field is required</span>}
      <br />
      <br />

      />
      {errors.content && <span>This field is required</span>}
      <br />
      <input type="submit" value="Submit" />
      {formLoading && <p>Loading</p>}
    </form>
  );
};

import { useForm } from "@refinedev/react-hook-form";

const PostCreatePage: React.FC = () => {
  const {
    refineCore: { onFinish, formLoading },
    register,

      </select>
      <br />
      <label>Content: </label>
      <br />
      <textarea
        {...register("content", { required: true })}
        rows={10}
        cols={50}
      />
      {errors.content && <span>This field is required</span>}
      <br />
      <br />
      <input type="submit" disabled={formLoading} value="Submit" />
      {formLoading && <p>Loading</p>}
    </form>
  );
};

It will be passed to the dataProvider's method as a params. This parameter is usually used to as a API endpoint path. It all depends on how to handle the resource in your dataProvider. See the creating a data provider section for an example of how resource are handled.

By default it reads the resource value from the current URL.

• When action is "create", it will be passed to the create method from the dataProvider.
• When action is "edit", it will be passed to the update and the getOne method from the dataProvider.
• When action is "clone", it will be passed to the create and the getOne method from the dataProvider.

useForm({
  refineCoreProps: {
    resource: "categories",
  },
});

If the resource is passed, the id from the current URL will be ignored because it may belong to a different resource. To retrieve the id value from the current URL, use the useParsed hook and pass the id value to the useForm hook.

import { useParsed } from "@refinedev/core";
import { useForm } from "@refinedev/react-hook-form";

const { id } = useParsed();

useForm({
  refineCoreProps: {
    resource: "custom-resource",
    id,
  },
});

Or you can use the setId function to set the id value.

import { useForm } from "@refinedev/react-hook-form";

const {
  refineCore: { setId },
} = useForm({
  refineCoreProps: {
    resource: "custom-resource",
  },
});

setId("123");

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 →

id is used for determining the record to edit or clone. By default, it uses the id from the route. It can be changed with the setId function or id property.

It is useful when you want to edit or clone a resource from a different page. Keep in mind that id is required when action: "edit" or action: "clone".

useForm({
  refineCoreProps: {
    action: "edit", // or clone
    resource: "categories",
    id: 1, // <BASE_URL_FROM_DATA_PROVIDER>/categories/1
  },
});

redirect is used for determining the page to redirect after the form is submitted. By default, it uses the list. It can be changed with the redirect property.

It can be set to "show" | "edit" | "list" | "create" or false to prevent the page from redirecting to the list page after the form is submitted.

useForm({
  refineCoreProps: {
    redirect: false,
  },
});

It's a callback function that will be called after the mutation is successful.

It receives the following parameters:

• data: Returned value from useCreate or useUpdate depending on the action.
• variables: The variables passed to the mutation.
• context: react-query context.
• isAutoSave: It's a boolean value that indicates whether the mutation is triggered by the autoSave feature or not.

useForm({
  refineCoreProps: {
    onMutationSuccess: (data, variables, context, isAutoSave) => {
      console.log({ data, variables, context, isAutoSave });
    },
  },
});

It's a callback function that will be called after the mutation is failed.

It receives the following parameters:

• data: Returned value from useCreate or useUpdate depending on the action.
• variables: The variables passed to the mutation.
• context: react-query context.
• isAutoSave: It's a boolean value that indicates whether the mutation is triggered by the autoSave feature or not.

useForm({
  refineCoreProps: {
    onMutationError: (data, variables, context, isAutoSave) => {
      console.log({ data, variables, context, isAutoSave });
    },
  },
});

You can use it to manage the invalidations that will occur at the end of the mutation.

By default it's invalidates following queries from the current resource:

• on create or clone mode: "list" and "many"
• on edit mode: "list", "many" and "detail"

useForm({
  refineCoreProps: {
    invalidates: ["list", "many", "detail"],
  },
});

If there is more than one dataProvider, you should use the dataProviderName that you will use. It is useful when you want to use a different dataProvider for a specific resource.

If you want to use a different dataProvider on all resource pages, you can use the dataProvider prop of the <Refine> component.

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

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

For more information about mutation modes, please check Mutation Mode documentation page.

useForm({
  refineCoreProps: {
    mutationMode: "undoable", // "pessimistic" | "optimistic" | "undoable",
  },
});

NotificationProvider is required for this prop to work.

After form is submitted successfully, useForm will call open function from NotificationProvider to show a success notification. With this prop, you can customize the success notification.

useForm({
  refineCoreProps: {
    successNotification: (data, values, resource) => {
      return {
        message: `Post Successfully created with ${data.title}`,
        description: "Success with no errors",
        type: "success",
      };
    },
  },
});

NotificationProvider is required for this prop to work.

After form is submit is failed, Refine will show a error notification. With this prop, you can customize the error notification.

useForm({
  refineCoreProps: {
    action: "create",
    resource: "post",
    errorNotification: (data, values, resource) => {
      return {
        message: `Something went wrong when deleting ${data.id}`,
        description: "Error",
        type: "error",
      };
    },
  },
});

{
    "message": "Error when updating <resource-name> (status code: ${err.statusCode})" or "Error when creating <resource-name> (status code: ${err.statusCode})",
    "description": "Error",
    "type": "error",
}

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).
• Providing additional parameters to the redirection path after the form is submitted.

Refer to the meta section of the General Concepts documentation for more information →

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

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

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

    const { data } = await httpClient.post(url, variables, { headers });

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

In addition to the meta property, you can also pass the queryMeta property to the useForm hook. This property is used to pass additional information to the useOne hook that is used to fetch the data in the edit and clone modes. This is useful when you have to apply different values to the useOne hook from the useCreate or useUpdate hook mutations.

useForm({
  queryMeta: {
    querySpecificValue: "someValue",
  },
});

If you have overlapping properties in both meta and queryMeta, the queryMeta property will be used.

In addition to the meta property, you can also pass the mutationMeta property to the useForm hook. This property is used to pass additional information to the useCreate or useUpdate hook mutations. This is useful when you have to apply different values to the useCreate or useUpdate hooks from the useOne hook query.

useForm({
  mutationMeta: {
    mutationSpecificValue: "someValue",
  },
});

If you have overlapping properties in both meta and mutationMeta, the mutationMeta property will be used.

Works only in action: "edit" or action: "clone" mode.

in edit or clone mode, Refine uses useOne hook to fetch data. You can pass queryOptions options by passing queryOptions property.

useForm({
  refineCoreProps: {
    queryOptions: {
      retry: 3,
    },
  },
});

This option is only available when action: "create" or action: "clone".

In create or clone mode, Refine uses useCreate hook to create data. You can pass mutationOptions by passing createMutationOptions property.

useForm({
  refineCoreProps: {
    queryOptions: {
      retry: 3,
    },
  },
});

This option is only available when action: "edit".

In edit mode, Refine uses useUpdate hook to update data. You can pass mutationOptions by passing updateMutationOptions property.

useForm({
  refineCoreProps: {
    queryOptions: {
      retry: 3,
    },
  },
});

When it's true, Shows a warning when the user tries to leave the page with unsaved changes. It can be used to prevent the user from accidentally leaving the page. Default value is false.

It can be set globally in Refine config.

useForm({
  refineCoreProps: {
    warnWhenUnsavedChanges: true,
  },
});

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.

useForm({
  refineCoreProps: {
    liveMode: "auto",
  },
});

The callback function that is executed when new events from a subscription are arrived.

useForm({
  refineCoreProps: {
    onLiveEvent: (event) => {
      console.log(event);
    },
  },
});

Params to pass to liveProvider's subscribe method.

If you want to save the form automatically after some delay when user edits the form, you can pass true to autoSave.enabled prop.

By default the autoSave feature does not invalidate queries. However, you can use the invalidateOnUnmount prop to invalidate queries upon unmount.

It also supports onMutationSuccess and onMutationError callback functions. You can use isAutoSave parameter to determine whether the mutation is triggered by autoSave or not.

autoSave feature operates exclusively in edit mode. Users can take advantage of this feature while editing data, as changes are automatically saved in editing mode. However, when creating new data, manual saving is still required.

onMutationSuccess and onMutationError callbacks will be called after the mutation is successful or failed.

To enable the autoSave feature, set the enabled parameter to true. By default, it is disabled.

useForm({
  refineCoreProps: {
    autoSave: {
      enabled: true,
    },
  },
});

Set the debounce time for the autoSave prop. Default value is 1000 milliseconds.

useForm({
  refineCoreProps: {
    autoSave: {
      enabled: true,
      debounce: 2000,
    },
  },
});

If you want to modify the data before sending it to the server, you can use onFinish callback function.

useForm({
  refineCoreProps: {
    autoSave: {
      enabled: true,
      onFinish: (values) => {
        return {
          foo: "bar",
          ...values,
        };
      },
    },
  },
});

This prop is useful when you want to invalidate the list, many and detail queries from the current resource when hook is unmounted. By default, it invalidates the list, many and detail queries associated with the current resource. Also, You can use the invalidates prop to select which queries to invalidate.

By default, the invalidateOnUnmount prop is set to false.

useForm({
  refineCoreProps: {
    autoSave: {
      enabled: true,
      invalidateOnUnmount: true,
    },
  },
});

If the action is set to "edit" or "clone" or if a resource with an id is provided, useForm will call useOne and set the returned values as the query property.

const {
  refineCore: { query },
} = useForm();

const { data } = query;

When in "create" or "clone" mode, useForm will call useCreate. When in "edit" mode, it will call useUpdate and set the resulting values as the mutation property."

const {
  refineCore: { mutation },
} = useForm();

const { data } = mutation;

useForm determine id from the router. If you want to change the id dynamically, you can use setId function.

const {
  refineCore: { id, setId },
} = useForm();

const handleIdChange = (id: string) => {
  setId(id);
};

return (
  <div>
    <input value={id} onChange={(e) => handleIdChange(e.target.value)} />
  </div>
);

"By default, after a successful mutation, useForm will redirect to the "list" page. To redirect to a different page, you can either use the redirect function to programmatically specify the destination, or set the redirect property in the hook's options.

In the following example we will redirect to the "show" page after a successful mutation.

const {
  refineCore: { onFinish, redirect },
} = useForm();

// --

const handleSubmit = async (e: React.FormEvent<HTMLFormElement>) => {
  e.preventDefault();
  const data = await onFinish(formValues);
  redirect("show", data?.data?.id);
};

// --

onFinish is a function that is called when the form is submitted. It will call the appropriate mutation based on the action property. You can override the default behavior by passing an onFinish function in the hook's options.

For example you can change values before sending to the API.

It contains all the props needed by the "submit" button within the form (disabled, onClick etc.). When saveButtonProps.onClick is called, it triggers handleSubmitfunction with onFinish. You can manually pass these props to your custom button.

Loading state of a modal. It's true when useForm is currently being submitted or data is being fetched for the "edit" or "clone" mode.

If autoSave is enabled, this hook returns autoSaveProps object with data, error, and status properties from mutation.
