Next.js

refine can be used with Next.js to SSR your pages. It doesn't get in the way and follows Next.js conventions and also provides helper modules when necessary.

Setup​

nextjs-router package provided by refine must be used for the routerProvider

npm i @refinedev/nextjs-router
TIP

We recommend using create refine-app to initialize your refine projects. It configures the project according to your needs including SSR with Next.js.

npm create refine-app@latest  -- -o refine-nextjs my-refine-nextjs-app
CAUTION

To make this example more visual, we used the @pankod/refine-antd package. If you are using Refine headless, you need to provide the components, hooks or helpers imported from the @pankod/refine-antd package.

Usage​

<Refine> must wrap your pages in a custom App component. This way your pages are integrated to refine.

pages/_app.tsx
import { AppProps } from "next/app";

import { Refine } from "@pankod/refine-core";
import {
  Layout,
  ReadyPage,
  useNotificationProvider,
  ErrorComponent,
} from "@pankod/refine-antd";

import dataProvider from "@pankod/refine-simple-rest";
import routerProvider from "@pankod/refine-nextjs-router";

import { PostList, PostEdit, PostCreate, PostShow } from "pages/posts";
import { UserList, UserShow } from "pages/users";

const API_URL = "https://api.fake-rest.refine.dev";

function MyApp({ Component, pageProps }: AppProps): JSX.Element {
  return (
    <Refine
      routerProvider={routerProvider}
      dataProvider={dataProvider(API_URL)}
      Layout={Layout}
      ReadyPage={ReadyPage}
      notificationProvider={useNotificationProvider}
      catchAll={<ErrorComponent />}
      resources={[
        {
          name: "posts",
          list: PostList,
          create: PostCreate,
          edit: PostEdit,
          show: PostShow,
        },
        {
          name: "users",
          list: UserList,
          show: UserShow,
        },
      ]}
    >
      <Component {...pageProps} />
    </Refine>
  );
}

export default MyApp;

Custom Page​

Let's say we want to show a list of users in /users. After creating users.tsx under pages in your Nextjs app, we can use the useTable hook to list the users in a table:

pages/users.tsx
import { LayoutWrapper } from "@pankod/refine-core";
import { useTable, List, Table } from "@pankod/refine-antd";

const API_URL = "https://api.fake-rest.refine.dev";
export const UserList: React.FC = () => {
  const { tableProps } = useTable<IUser>({
    resource: "users",
  });

  return (
    <LayoutWrapper>
      <List title="Users">
        <Table {...tableProps} rowKey="id">
          <Table.Column dataIndex="id" title="ID" sorter />
          <Table.Column dataIndex="firstName" title="Name" />
        </Table>
      </List>
    </LayoutWrapper>
  );
};
interface IUser {
  id: number;
  firstName: string;
}

export default UserList;
TIP

If you want to handle your resource with a custom page or create a custom page with or without a resource, these will not be visible in the <Sider /> component. You can trick the <Sider/> by passing an empty resource to show your custom route in it.

Example
const App = () => (
  <Refine
    resources={[
      // This will add an item to `<Sider/>` with route `/my-custom-item`
      { name: "my-custom-item", list: () => null },
    ]}
  />
);
CAUTION

Notice how we passed resource prop to useTable. This is necessary since for useTable to be able to get resource name from route, it needs to be a route parameter in a dynamic route. Refer here where standard CRUD pages can be built with dynamic routing.

CAUTION

We also used <LayoutWrapper> to show the page in the layout provided to <Refine>. This is deliberately opt-in to provide flexibility. If you're building a standard CRUD page layout can be baked in automatically.

SSR​

refine uses react-query in its hooks for data management. Following react-query's guide, SSR can be achieved like this:

pages/users.tsx
import { GetServerSideProps } from "next";
import dataProvider from "@pankod/refine-simple-rest";
import {
  LayoutWrapper,
  GetListResponse,
} from "@pankod/refine-core";
import { useTable, List, Table } from "@pankod/refine-antd";

const API_URL = "https://api.fake-rest.refine.dev";
export const UserList: React.FC<{ users: GetListResponse<IUser> }> = ({
  users,
}) => {
  const { tableProps } = useTable<IUser>({
    resource: "users",
    queryOptions: {
      initialData: users,
    },
  });

  return (
    <LayoutWrapper>
      <List title="Users">
        <Table {...tableProps} rowKey="id">
          <Table.Column dataIndex="id" title="ID" sorter />
          <Table.Column dataIndex="firstName" title="Name" />
        </Table>
      </List>
    </LayoutWrapper>
  );
};

export const getServerSideProps: GetServerSideProps = async (context) => {
  const data = await dataProvider(API_URL).getList({
    resource: "users",
  });

  return {
    props: { users: data },
  };
};

interface IUser {
  id: number;
  firstName: string;
}

export default UserList;

We use the getList method from our dataProvider to fetch users data and pass through props as conventionally done in Next.js. Then users data is available in the props of our /users page. useTable can take options for underlying react-query queries with queryOptions. Passing users data to its initialData loads the data on server side.

TIP

We used getList from dataProvider but data can be fetched in any way you desire.

Standard CRUD Page​

nextjs-router package provides NextRouteComponent for routing in refine resources. Simply export the component from the page and add a data fetching function. While you can create pages with defined params like [resource]/[action]/[id].tsx, we recommend using a catch-all route to handle all refine routing in a single file. You can start by creating a [[...refine]].tsx file under pages in your Nextjs app:

pages/[[...refine]].tsx
export { NextRouteComponent as default } from "@pankod/refine-nextjs-router";
INFORMATION

You can also define routes without using [[...refine]].tsx file like below, but a catch-all route is an easier approach with nested route support.

Export NextRouteComponent as default in the following pages:

  • pages/[resource].tsx
  • pages/[resource]/[action].tsx
  • pages/[resource]/[action]/[id].tsx
  • pages/index.tsx

NextRouteComponent will use route parameters resource and action and render the associated component defined in resources.

  • list component will be rendered for /[resource] route
  • create, edit and show will be rendered for /[resource]/[action] and /[resource]/[action]/[id] routes
  • For the root / route, it will render DashboardPage if it's defined and if not will navigate to the first resource in resources.
CAUTION

NextRouteComponent will wrap the page with Layout provided to <Refine>

SSR​

NextRouteComponent accepts a initialData prop for SSR data.

type NextRouteComponentProps = {
  initialData?: any;
};

initialData must be passed as props from getServerSideProps. NextRouteComponent will pass this data as initialData to the list, create, edit, and show components.

For example, for a list component that will be rendered for /[resource], the page can use SSR like this:

pages/[[...refine]].tsx
export { NextRouteComponent as default } from "@pankod/refine-nextjs-router";
import { handleRefineParams } from "@pankod/refine-nextjs-router";
import dataProvider from "@pankod/refine-simple-rest";

import { GetServerSideProps } from "next";

const API_URL = "https://api.fake-rest.refine.dev";

export const getServerSideProps: GetServerSideProps = async (context) => {
  const { resource, action, id } = handleRefineParams(context.params?.refine);

  try {
    if (resource && action === "show" && id) {
      const data = await dataProvider(API_URL).getOne({
        // we're slicing the resource param to get the resource name from the last part
        resource: resource.slice(resource.lastIndexOf("/") + 1),
        id,
      });

      return {
        props: {
          initialData: data,
        },
      };
    } else if (resource && !action && !id) {
      const data = await dataProvider(API_URL).getList({
        // we're slicing the resource param to get the resource name from the last part
        resource: resource.slice(resource.lastIndexOf("/") + 1),
      });

      return {
        props: {
          initialData: data,
        },
      };
    }
  } catch (error) {
    return { props: {} };
  }

  return { props: {} };
};

And in the list component for a resource e.g. "posts":

src/components/posts/list.tsx
import { GetListResponse, IResourceComponentsProps } from "@pankod/refine-core";
import { useTable, List, Table } from "@pankod/refine-antd";

export const PostList: React.FC<
  IResourceComponentsProps<GetListResponse<IPost>>
> = ({ initialData }) => {
  const { tableProps } = useTable<IPost>({
    queryOptions: {
      initialData,
    },
  });

  return (
    <List>
      <Table {...tableProps} rowKey="id">
        <Table.Column dataIndex="id" title="ID" />
        <Table.Column dataIndex="status" title="Status" />
      </Table>
    </List>
  );
};

interface IPost {
  id: number;
  firstName: string;
}
TIP

You can also achieve SSR with getStaticProps and getStaticPaths for static generation. All you need to do is to add the paths you want to statically generate to getStaticPaths and pass the data as initialData from getStaticProps.

Server Side Authentication​

nextjs-router package provides checkAuthentication to easily handle server side authentication.

pages/[[...refine]].tsx
export { NextRouteComponent as default } from "@pankod/refine-nextjs-router";
import { checkAuthentication } from "@pankod/refine-nextjs-router";

import { GetServerSideProps } from "next";

import { authProvider } from "../../src/authProvider";

const API_URL = "https://api.fake-rest.refine.dev";

export const getServerSideProps: GetServerSideProps = async (context) => {
  const { isAuthenticated, ...props } = await checkAuthentication(
    authProvider,
    context,
  );

  if (!isAuthenticated) {
    return props;
  }

  return {
    props: {},
  };
};

checkAuthentication expects your authProvider and getServerSideProps's context. It uses the checkAuth from the authProvider to check for authentication and returns isAuthenticated accordingly. It also returns a redirect object to handle unauthenticated case. It redirects to /login while keeping the original route to be navigated to after successful login.

syncWithLocation and Query Parameters in SSR​

If syncWithLocation is enabled, query parameters must be handled while doing SSR.

pages/users.tsx
import { GetServerSideProps } from "next";
import { parseTableParamsFromQuery } from "@pankod/refine-core";
import dataProvider from "@pankod/refine-simple-rest";

const API_URL = "https://api.fake-rest.refine.dev";

export const getServerSideProps: GetServerSideProps = async (context) => {
  const { parsedCurrent, parsedPageSize, parsedSorter, parsedFilters } =
    parseTableParamsFromQuery(context.query);
  const data = await dataProvider(API_URL).getList({
    resource: "users",
    filters: parsedFilters,
    pagination: {
      current: parsedCurrent || 1,
      pageSize: parsedPageSize || 10,
    },
    sort: parsedSorter,
  });

  return {
    props: { users: data },
  };
};

parseTableParams parses the query string and returns query parameters(refer here for their interfaces). They can be directly used for dataProvider methods that accepts them.

appDir Support​

Next.js introduced a new way of defining pages within the app/ directory. This new directory has support for layouts, nested routes, and uses Server Components by default. To learn more about the feature check out Next.js Beta docs

refine also follows this feature and provides a way to use appDir with your refine apps.

CAUTION

app/ is currently in beta and is not recommended for production use in Next.js. In refine, we're providing the app/ support as experimental and not recommended for production use.

To start using app/ with refine, you need to set create the refine routes in your /app directory with the following convention:


your-project
└── app
    └── [[...refine]]
        ├── layout.tsx
        └── page.tsx

Initializing <Refine/> in layout.tsx

app/[[...refine]]/layout.tsx
"use client";

import routerProvider from "@pankod/refine-nextjs-router/app";

export default function RefineLayout({
  children,
  params,
}: {
  children: React.ReactNode;
  params: Record<"refine", string[]>;
}) {
  return (
    <Refine
      routerProvider={routerProvider.call({ params })}
      /* ... */
    >
      {children}
    </Refine>
  );
}

We need to bind the params to the routerProvider and call it to initialize the routerProvider. This is because the params are not available via hooks for refine to use.

Creating page.tsx

app/[[...refine]]/page.tsx
"use client";

import { NextRouteComponent } from "@pankod/refine-nextjs-router/app";

export default NextRouteComponent;

Note that we're importing NextRouteComponent from @pankod/refine-nextjs-router/app instead of @pankod/refine-nextjs-router. This is because we're using the app/ directory and we need to import the app version of the NextRouteComponent.

NOTE

"use client"; is a directive that instructs Next.js to opt-out from Server Components. This is because refine and dependencies are not yet compatible with Server Components. That's why we're using it in both layout.tsx and page.tsx files.

NOTE

checkAuthentication does not work with app/ directory. You need to handle the authentication of your views while using app/ directory.

refine aims to provide a middleware for app/ directory to substitute checkAuthentication but it's not available yet.

INFORMATION

You can find the app/ directory example with refine in examples/nextjs/appdir
