<Refine>

A dataProvider is the place where a Refine app communicates with an API. Data providers also act as adapters for Refine, making it possible for it to consume different API's and data services. A dataProvider makes HTTP requests and returns response data back using predefined methods.

Refer to the Data Provider documentation for detailed information. →

Multiple data providers can be used with Refine, if you have multiple data providers, you can pass them to the dataProvider prop as an object.

import { Refine } from "@refinedev/core";
import { defaultDataProvider, exampleDataProvider } from "./data-providers";

const App = () => (
  <Refine
    dataProvider={{
      // `default` key must be defined to determine the default data provider
      default: defaultDataProvider,
      example: exampleDataProvider,
    }}
  />
);

Refine provides a simple interface from the routerProvider prop to infer the resource from route, pass, parse and sync the query parameters and handle navigation operations. This provider and its properties are optional but it is recommended to use it to get the most out of Refine. Bindings to pass to the routerProvider prop are provided for the following libraries:

• React Router via @refinedev/react-router-v6
• Next.js via @refinedev/nextjs-router
• Remix via @refinedev/remix-router

It's also possible to create a custom router bindings for your routing needs.

Refer to the Router Provider documentation for detailed information. →

resources is the main building block of a Refine app. A resource represents an entity in an endpoint in the API (e.g. https://api.fake-rest.refine.dev/posts). It serves as a bridge between the data from the API and the pages in the app, allowing pages to interact with the data from the API.

Here's an app that consumes the https://api.fake-rest.refine.dev/posts endpoint as a resource to list multiple items, edit or create an item and show a single item.

Routes for the action pages that are for interacting with the CRUD API operations are passed as a resource element to resources.

import { Refine } from "@refinedev/core";
import dataProvider from "@refinedev/json-server";

const App = () => (
  <Refine
    dataProvider={dataProvider("https://api.example.com")}
    resources={[
      {
        name: "posts",
        list: "/posts", // Means that the list action of this resource will be available at /posts in your app
        create: "/posts/create", // Means that the create action of this resource will be available at /posts/create in your app
        edit: "/posts/edit/:id", // Means that the edit action of this resource will be available at /posts/edit/:id in your app
        show: "/posts/show/:id", // Means that the show action of this resource will be available at /posts/show/:id in your app
      },
    ]}
  />
);

A string value that identifies a resource in the API. Interacting with the data in a resource will be done using an endpoint determined by the name:

https://api.fake-rest.refine.dev/posts
https://api.fake-rest.refine.dev/posts/1

The identifier value serves as the main matching key for a resource. It allows you to effectively differentiate between multiple resources that share the same name.

There are scenarios where you may have multiple resources with the same name but different meta values. For instance, you might want a posts resource utilizing the default data provider and another posts resource utilizing the "typicode" data provider. In this case, you can use the identifier to differentiate between them.

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

<Refine
    ...
    dataProvider={{
        default: defaultDataProvider,
        typicode: typicodeDataProvider,
    }}
    resources={[
        {
            name: "posts",
            identifier: "posts",
            meta: {
                foo: "bar",
            },
        },
        {
            name: "posts",
            identifier: "featured-posts",
            meta: {
                foo: "baz",
                filter: {
                    featured: true,
                },
                dataProviderName: "typicode",
            },
        },
    ]}
>
...
</Refine>;

As you can see in the example above, we have two resources with the same name but different identifier values. Also, both resources have different meta values. Using the identifier, we can differentiate between the two resources like so:

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

useTable({
  resource: "featured-posts",
});

const typicodeDataProvider = {
  //...
  getList: async ({ resource, meta }) => {
    console.log(resource); // "posts"
    console.log(meta); // { foo: "baz", filter: { featured: true } }
  },
  //...
};

The list path of the resource. The value assigned to the list will be treated as the list action path for the resource and the navigation operations will be performed on this path.

You can also pass a component to this property. In this case the default value for the path will be used, which is the /${name}.

There's also a third option, which is to pass an object with the component and path properties. This allows you to customize the path of the list action.

The create path of the resource. The value assigned to the create will be treated as the create action path for the resource and the navigation operations will be performed on this path.

You can also pass a component to this property. In this case the default value for the path will be used, which is the /${name}/create.

There's also a third option, which is to pass an object with the component and path properties. This allows you to customize the path of the list action.

The edit path of the resource. The value assigned to the edit will be treated as the edit action path for the resource and the navigation operations will be performed on this path.

You can also pass a component to this property. In this case the default value for the path will be used, which is the /${name}/edit/:id.

There's also a third option, which is to pass an object with the component and path properties. This allows you to customize the path of the list action.

The show path of the resource. The value assigned to the show will be treated as the show action path for the resource and the navigation operations will be performed on this path.

You can also pass a component to this property. In this case the default value for the path will be used, which is the /${name}/show/:id.

There's also a third option, which is to pass an object with the component and path properties. This allows you to customize the path of the list action.

meta can have any kind of property. It is used to store additional information about the resource. This property you pass can be received from the useResource. Listed below are the properties that are used by Refine or its libraries.

Name to show in the menu. The plural form of the resource name is shown by default.

<Refine
  resources={[
    {
      /* ... */
      meta: { label: "custom" },
    },
  ]}
/>

An icon element can be passed as properties for the icon in the menu.

<Refine
  resources={[
    {
      /* ... */
      meta: { icon: <CustomIcon /> },
    },
  ]}
/>

This value is used by the Crud views to determine whether to show the delete button or not.

<Refine
  resources={[
    {
      /* ... */
      meta: { canDelete: true },
    },
  ]}
/>

You can set this value if you want to nest your resource into another resource. Usually this value represents the name of the parent resource but you can also pass a custom string. In this case, it will still be interpreted as a parent resource. This value is used by the useMenu and useBreadcrumb hooks.

<Refine
  resources={[
    { name: "parent" },
    {
      name: "child",
      meta: { parent: "parent" },
    },
  ]}
/>

Default data provider name to use for the resource. If not specified, the default data provider will be used.

<Refine
  dataProvider={{
    default: defaultDataProvider,
    typicode: typicodeDataProvider,
  }}
  resources={[
    {
      /* ... */
      meta: { dataProviderName: "typicode" },
    },
  ]}
/>

Can be used to hide a resource in Sider. This resource is also filtered in the useMenu hook.

<Refine
  resources={[
    {
      /* ... */
      meta: { hide: true },
    },
  ]}
/>

Custom route name for the resource.

authProvider handles authentication logic like login, logout flow, and checking user credentials. It is an object with methods that Refine uses when necessary.

Refer to Auth Provider documentation for detailed information. →

The i18nProvider property lets you add i18n support to your app. Making you able to use any i18n framework.

Refer to i18n documentation for detailed information. →

accessControlProvider is the entry point for implementing access control for Refine apps.

Refer to access control documentation for detailed information. →

Refine lets you add Realtime support to your app via liveProvider. It can be used to update and show data in Realtime throughout your app.

Refer to live provider documentation for detailed information. →

notificationProvider handles notification logic. It is an object with methods that Refine uses when necessary.

Refer to the Notification Provider documentation for detailed information. →

options is used to configure the app.

When the dataProvider returns rejected promise with errors field, the useForm hook will set the errors state with the errors returned from the dataProvider.

Refer to Server Side Validation section of the Forms guide for detailed information. →

To disable this behavior, you can set the disableServerSideValidation option to true.

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

const App = () => (
  <Refine
    options={{ disableServerSideValidation: true }}
  >
    {/* ... */}
  </Refine>
);

Customize or disable the breadcrumb. By default it uses the Breadcrumb component from the respective package.

Refer to the Layouts and Menus section of UI Libraries guide for further information. →

import { Breadcrumb } from "@refinedev/antd";

const App = () => (
  <Refine
    options={{
      // Or you can pass `false` to disable the breadcrumbs
      breadcrumb: (
        <div
          style={{
            padding: "3px 6px",
            border: "2px dashed cornflowerblue",
          }}
        >
          <Breadcrumb />
        </div>
      ),
    }}
  />
);

mutationMode determines which mode the mutations run with. (e.g. useUpdate, useDelete).

const App = () => (
  <Refine
    options={{ mutationMode: "optimistic" }}
  />
);

pessimistic: The mutation runs immediately. Redirection and UI updates are executed after the mutation returns successfully. This is the default setting.

optimistic: The mutation is applied locally, and redirection and UI updates are executed immediately as if the mutation is successful. If the mutation returns with an error, UI updates accordingly.

undoable: The mutation is applied locally, and redirection and UI updates are executed immediately as if the mutation is successful. Waits for a customizable amount of timeout before mutation is applied. During the timeout, mutation can be canceled from the notification with the ?undo? button. UI will revert accordingly.

Refer to the Mutation Mode docs for further information. →

The duration of the timeout period in undoable mode is shown in milliseconds. Mutations can be canceled during this period. This period can also be set on the supported data hooks. The value set in hooks will override the value set with undoableTimeout. undoableTimeout has a default value of 5000.

const App = () => (
  <Refine
    options={{ mutationMode: "undoable", undoableTimeout: 3500 }}
  />
);

List query parameter values can be edited manually by typing directly in the URL. syncWithLocation's default value is false, so you need to set it to true to activate the feature.

Form hooks like useDrawerForm and useModalForm also have a syncWithLocation property but the value of this option has no effect on these hooks. You'll still need to set the syncWithLocation property in hooks to true to activate this feature.

When syncWithLocation is active, the URL on the listing page shows query parameters like those shown below:

/posts?current=1&pageSize=8&sort[]=createdAt&order[]=desc

Users can change the current page, items count per page, and sort and filter parameters.

When you have unsaved changes and try to leave the current page, Refine shows a confirmation modal box. warnWhenUnsavedChanges's default value is false, so you need to set it to true to activate the feature.

This feature also requires UnsavedChangesNotifier component to be mounted. You can import this component from your router package.

liveMode controls whether to update data automatically or not, with auto and manual respectively if a related live event is received. The off value can be used to avoid creating a subscription all together.

For more information, refer to the live provider documentation →

Refine implements a simple and transparent telemetry module for collecting usage statistics defined in a very limited scope. This telemetry module is used to improve the Refine experience. You can disable this by setting disableTelemetry to true.

For more information, refer to the Refine telemetry documentation →

By default, Refine redirects to the list page of the resource after a successful form mutation. To change this behavior based on the form action, set redirect as follows:

const App = () => (
  <Refine
    options={{
      redirect: {
        // If the resource doesn't have a show page defined, the user will be redirected to the list page.
        afterCreate: "show",
        // If the mutation mode is `undoable` or `optimistic`, the redirect happens before the mutation succeeds. Therefore, if there is no known `id` value, the user will be redirected to the list page.
        afterClone: "edit",
        // If set to `false`, no redirect is performed after a successful form mutation.
        afterEdit: false,
      },
    }}
  />
);

Config for React Query client that Refine uses.

const App = () => (
  <Refine
    options={{
      reactQuery: {
        clientConfig: {
          defaultOptions: {
            queries: {
              staleTime: Infinity,
            },
          },
        },
      },
    }}
  />
);

Also, you can use your own QueryClient.

import { QueryClient } from "@tanstack/react-query";

const myQueryClient = new QueryClient();

const App = () => (
  <Refine
    options={{
      reactQuery: {
        clientConfig: myQueryClient,
      },
    }}
  />
);

For more information, refer to the QueryClient documentation →

React Query Devtools are removed from the @refinedev/core and this prop is no longer supported for the configuration of the devtools. You can use the @tanstack/react-query-devtools in your app directly to use the devtools. For more information, please check out FAQ - How to use React Query Devtools with Refine?

For more information, refer to the Devtools documentation →

The textTransformers option in Refine is used to transform the resource name displayed on the user interface (UI). By default, if you define a resource named posts, Refine will display it as Posts. Similarly, when you delete a record, notification messages will be shown as Post deleted successfully..

You have the flexibility to customize these messages by using the textTransformers option. For instance, if you wish to disable any transformation, you can set the textTransformers option as shown in the example below:

const App = () => (
  <Refine
    // ...
    options={{
      textTransformers: {
        humanize: (text) => text,
        plural: (text) => text,
        singular: (text) => text,
      },
    }}
  />
);

The function converts the resource name to a more human-readable format. The default value uses the humanize-string library.

The function converts the resource name to its plural form. The default value uses the pluralize library.

The function converts the resource name to its singular form. The default value uses the pluralize library.

If you want loading overtime for the request, you can use the overtime object. It is useful when you want to show a loading indicator when the request takes too long.

const App = () => (
  <Refine
    options={{
      overtime: {
        interval: 1000, // default value is 1000
        onInterval: (elapsedInterval, context) => {
          console.log(elapsedInterval, context);
        },
      },
    }}
  />
);

The interval value in milliseconds. The default value is 1000.

The callback function that will be called on every interval. The default value is undefined.

The callback function receives two parameters:

• elapsedInterval: The elapsed interval in milliseconds.
• context: { resource?: IResourceItem; resourceName?: string; id?: BaseKey, action?: Action }

With @refinedev/core's v4.35.0, Refine introduced new query and mutation keys which are more structured and easy to construct. These keys are used in all data, auth, access control and audit log queries and mutations.

By default, Refine uses the legacy keys for backward compatibility and in the future versions it will switch to using the new query keys. You can easily switch to using new keys by setting useNewQueryKeys to true.

Callback to handle all live events.

For more information, refer to the live provider documentation →

When the app is navigated to a non-existent route, Refine shows a default error page. A custom error component can be used for this error page by passing the customized component to the catchAll property:

const CustomErrorPage = <div>Page not found</div>;

const App = () => (
  <Refine
    catchAll={CustomErrorPage}
  />
);

Refine has a default login page form which is served on the /login route when the authProvider configuration is provided.

Custom login component can be passed to the LoginPage property.

const CustomLoginPage = () => <div> Custom Login Page </div>;

const App = () => (
  <Refine
    LoginPage={CustomLoginPage}
  />
);

A custom dashboard page can be passed to the DashboardPage prop which is accessible on the root route.

The dashboard item will appear at the top of the sider menu. If DashboardPage is not given, the first resource of resources will be shown.

const CustomDashboardPage = () => <div> Custom Dashboard Page </div>;

const App = () => (
  <Refine
    DashboardPage={CustomDashboardPage}
  />
);

Refine shows a default ready page on the root route when no resources is passed to the <Refine>.

Custom ready page component can be set by passing to the ReadyPage property?.

const CustomReadyPage = () => <div> Custom Ready Page </div>;

const App = () => (
  <Refine
    ReadyPage={CustomReadyPage}
  />
);

The default sidebar can be customized by using Refine hooks and passing custom components to the Sider property.

For more information, refer to the useMenu hook documentation →

The default app footer can be customized by passing the Footer property.

const CustomFooter = () => <div>Custom Footer</div>;

const App = () => (
  <Refine
    Footer={CustomFooter}
  />
);

The default app header can be customized by passing the Header property.

const CustomHeader = () => <div>Custom Header</div>;

const App = () => (
  <Refine
    Header={CustomHeader}
  />
);

The default layout can be customized by passing the Layout property.

Layout property will receive individual layout components as property.

const App = () => (
  <Refine
    Layout={({ children, Sider, Footer, Header, OffLayoutArea }) => (
      <AntdLayout style={{ minHeight: "100vh", flexDirection: "row" }}>
        {Sider && <Sider />}
        <AntdLayout>
          {Header && <Header />}
          <AntdLayout.Content>
            <div style={{ padding: 24, minHeight: 360 }}>{children}</div>
          </AntdLayout.Content>
          {Footer && <Footer />}
        </AntdLayout>
        {OffLayoutArea && <OffLayoutArea />}
      </AntdLayout>
    )}
  />
);

A completely custom layout can also be implemented instead of the Refine's default:

const App = () => (
  <Refine
    Layout={({ children }) => (
      <div style={{ display: "flex", flexDirection: "column" }}>
        <div>Custom Layout</div>
        <div>{children}</div>
      </div>
    )}
  />
);

The component wanted to be placed out of the app layout structure can be set by passing to the OffLayoutArea prop.

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

const App = () => (
  <Refine
    OffLayoutArea={() => <div>Some elements to place outside the layout</div>}
  />
);

The app title can be set by passing the Title property.

const CustomTitle = ({ collapsed }) => (
  <div>{collapsed ? "Collapsed Title" : "Full Title"}</div>
);

const App = () => (
  <Refine
    Title={CustomTitle}
  />
);
