### Refine App Initialization with React Router

Source: https://refine.dev/docs/index

This snippet shows the main App component setup for a Refine application. It initializes Refine with a REST data provider, React Router, authentication provider, and i18n provider. It defines resources for 'products' and 'categories' and sets up authenticated routes for CRUD operations and public routes for authentication.

```tsx
// file: /App.tsx 
import { Authenticated, type I18nProvider, Refine } from "@refinedev/core";
import dataProvider from "@refinedev/simple-rest";

import routerProvider, {
  CatchAllNavigate,
  NavigateToResource,
} from "@refinedev/react-router";
import { BrowserRouter, Outlet, Route, Routes } from "react-router";

import CssBaseline from "@mui/material/CssBaseline";
import GlobalStyles from "@mui/material/GlobalStyles";
import {
  AuthPage,
  ErrorComponent,
  RefineSnackbarProvider,
  ThemedLayout,
  useNotificationProvider,
} from "@refinedev/mui";

import { useTranslation } from "react-i18next";

import { authProvider } from "./authProvider";
import { Header } from "./components/header";
import { ColorModeContextProvider } from "./contexts/color-mode";

import {
  CategoryCreate,
  CategoryEdit,
  CategoryList,
  CategoryShow,
} from "@/pages/categories";
import {
  ProductCreate,
  ProductEdit,
  ProductList,
  ProductShow,
} from "@/pages/products";

function App() {
  const { t, i18n } = useTranslation();

  const i18nProvider: I18nProvider = {
    translate: (key, params) => t(key, params).toString(),
    changeLocale: (lang: string | undefined) => i18n.changeLanguage(lang),
    getLocale: () => i18n.language,
  };

  return (

### Refine Internationalization Setup (TypeScript)

Source: https://refine.dev/docs/index

Configures i18next for internationalization in a React application using the @refinedev/core framework. It integrates with i18next-browser-languagedetector and i18next-xhr-backend to detect user language and load translations from JSON files.

```typescript
import i18n from "i18next";
import detector from "i18next-browser-languagedetector";
import Backend from "i18next-xhr-backend";
import { initReactI18next } from "react-i18next";

i18n
  .use(Backend)
  .use(detector)
  .use(initReactI18next)
  .init({
    supportedLngs: ["en", "de"],
    backend: {
      loadPath: "/locales/{{lng}}/{{ns}}.json",
    },
    ns: ["common"],
    defaultNS: "common",
    fallbackLng: ["en", "de"],
  });

export default i18n;

```

### Product List with DataGrid and Refine MUI

Source: https://refine.dev/docs/index

This snippet defines the Product List page using Refine's `List` component and Material UI's `DataGrid`. It fetches product data and category information to display a table with columns for name, category, price, and actions. The category is displayed as its title, and the price is formatted as currency. Action buttons for showing, editing, and deleting products are included.

```tsx
// file: /pages/products/list.tsx 
import { useMemo } from "react";

import {
  useGetLocale,
  useList,
  useTranslate,
} from "@refinedev/core";

import { DataGrid, type GridColDef } from "@mui/x-data-grid";
import {
  DeleteButton,
  EditButton,
  List,
  NumberField,
  ShowButton,
  useDataGrid,
} from "@refinedev/mui";

export const ProductList = () => {
  const { dataGridProps } = useDataGrid();

  const locale = useGetLocale()();

  const translate = useTranslate();

  const { result: { data: categories }, query: { isLoading: categoryLoading } } = useList({
    resource: "categories",
    pagination: {
      mode: "off",
    },
  });

  const columns = useMemo<GridColDef[]>(
    () => [
      {
        field: "name",
        flex: 1,
        headerName: translate("products.fields.name"),
        minWidth: 300,
      },
      {
        field: "category",
        flex: 1,
        headerName: translate("products.fields.category"),
        minWidth: 200,
        valueGetter: ({ row }) => {
          const value = row?.category;
          return value;
        },
        display: "flex",
        renderCell: function render({ value }) {
          return categoryLoading ? (
            <>{translate("loading")}</>
          ) : (
            categories?.data?.find((item) => item.id === value?.id)?.title ??
              null
          );
        },
      },
      {
        field: "price",
        flex: 1,
        headerName: translate("products.fields.price"),
        minWidth: 100,
        maxWidth: 150,
        display: "flex",
        renderCell: ({ value }) => {
          return (
            <NumberField
              value={value}
              locale={locale}
              options={{ style: "currency", currency: "USD" }}
            />
          );
        },
      },
      {
        field: "actions",
        headerName: translate("table.actions"),
        sortable: false,
        display: "flex",
        renderCell: function render({ row }) {
          return (
            <>
              <ShowButton hideText recordItemId={row.id} />
              <EditButton hideText recordItemId={row.id} />
              <DeleteButton hideText recordItemId={row.id} />
            </>
          );
        },
        align: "center",
        headerAlign: "center",
        minWidth: 80,
      },
    ],
    [categoryLoading, categories, locale, translate],
  );

  return (
    <List>
      <DataGrid {...dataGridProps} columns={columns} />
    </List>
  );
};

```

--------------------------------

### Product Show Page with Refine MUI

Source: https://refine.dev/docs/index

This snippet defines the Product Show page using Refine's `Show` component and Material UI components. It displays product details, including name, price, and material. The price is formatted as currency using `NumberField`. Skeleton loaders are used for a better user experience while data is being fetched.

```tsx
// file: /pages/products/show.tsx 
import { useOne, useShow, useTranslate } from "@refinedev/core";

import Skeleton from "@mui/material/Skeleton";
import Stack from "@mui/material/Stack";
import Typography from "@mui/material/Typography";

import {
  NumberField,
  Show,
  TextFieldComponent as TextField,
} from "@refinedev/mui";
import type { Product } from "./types";

```

### Refine App Configuration with MUI and React Router

Source: https://refine.dev/docs/index

This snippet shows the main App.tsx file for a Refine application. It configures the Refine core with data providers, router, authentication, and i18n providers. It also sets up routing for products and categories, including list, create, edit, and show views, utilizing MUI components for layout and authentication pages.

```tsx
import { Authenticated, type I18nProvider, Refine } from "@refinedev/core";
import dataProvider from "@refinedev/simple-rest";

import routerProvider, {
  CatchAllNavigate,
  NavigateToResource,

  ThemedLayout,
  useNotificationProvider,
} from "@refinedev/mui";

import { useTranslation } from "react-i18next";

import { authProvider } from "./authProvider";
import { Header } from "./components/header";
import { ColorModeContextProvider } from "./contexts/color-mode";

import {
  CategoryCreate,
  CategoryEdit,
  CategoryList,
  CategoryShow,
} from "@/pages/categories";
import {
  ProductCreate,
  ProductEdit,
  ProductList,
  ProductShow,
} from "@/pages/products";

function App() {
  const { t, i18n } = useTranslation();

  const i18nProvider: I18nProvider = {
    translate: (key, params) => t(key, params).toString(),
    changeLocale: (lang: string | undefined) => i18n.changeLanguage(lang),
    getLocale: () => i18n.language,
  };

  return (
    <BrowserRouter>

### Product Create Form with Autocomplete

Source: https://refine.dev/docs/index

A form for creating a new product using Refine and React Hook Form. It includes fields for product name and description, and an autocomplete field for selecting a category. The component uses `useForm` for form state management and `useAutocomplete` for category suggestions.

```tsx
// file: /pages/products/create.tsx 
import { type HttpError, useTranslate } from "@refinedev/core";
import { useForm } from "@refinedev/react-hook-form";
import { Controller } from "react-hook-form";

import { Autocomplete, Box, TextField } from "@mui/material";
import { Create, useAutocomplete } from "@refinedev/mui";
import type { Product } from "./types";

export const ProductCreate: React.FC = () => {
  const translate = useTranslate();
  const {
    saveButtonProps,
    refineCore: { formLoading },
    register,
    control,
    formState: { errors },
  } = useForm<Product, HttpError, Product>();

  const { autocompleteProps: categoryAutocompleteProps } = useAutocomplete({
    resource: "categories",
  });

  return (
    <Create isLoading={formLoading} saveButtonProps={saveButtonProps}>
      <Box
        component="form"
        sx={{ display: "flex", flexDirection: "column" }}
        autoComplete="off"
      >
        <TextField
          {...register("name", {
            required: translate("form.required"),
          })}
          error={!!errors?.name}
          helperText={<>{errors?.name?.message}</>}
          margin="normal"
          fullWidth
          slotProps={{
            inputLabel: {
              shrink: true,
            },
          }}
          type="text"
          label={translate("products.fields.name")}
          name="name"
        />
        <TextField
          {...register("description", {
            required: translate("form.required"),
          })}

```

### Refine Color Mode Context Provider (TypeScript)

Source: https://refine.dev/docs/index

Provides a React context for managing the application's color mode (light/dark). It integrates with Material UI's ThemeProvider and Refine's themes, allowing users to switch between modes and persisting the preference in localStorage. It also respects the system's color scheme preference.

```typescript
import { ThemeProvider } from "@mui/material/styles";
import { RefineThemes } from "@refinedev/mui";
import type React from "react";
import {
  type PropsWithChildren,
  createContext,
  useEffect,
  useState,
} from "react";

type ColorModeContextType = {
  mode: string;
  setMode: () => void;
};

export const ColorModeContext = createContext<ColorModeContextType>(
  {} as ColorModeContextType,
);

export const ColorModeContextProvider: React.FC<PropsWithChildren> = ({
  children,
}) => {
  const colorModeFromLocalStorage = localStorage.getItem("colorMode");
  const isSystemPreferenceDark = window?.matchMedia(

### Display Product Details in React with Refine

Source: https://refine.dev/docs/index

This React component uses the Refine framework to display product details. It fetches product data and its associated category, handling loading and error states with skeleton loaders. Dependencies include React, Refine hooks (useTranslate, useShow, useOne), and Material UI components.

```javascript
export const ProductShow: React.FC = () => {
  const translate = useTranslate();
  const {
    result: product,
    query: { isLoading },
  } = useShow<Product>();

  const {
    data: categories,
    isLoading: categoryLoading,
    isError: categoryError,
  } = useOne({
    resource: "categories",
    id: product?.category?.id,
    queryOptions: {
      enabled: !!product?.category?.id,
    },
  });

  return (
    <Show isLoading={isLoading}>
      <Stack gap={1}>
        <Typography variant="body1" fontWeight="bold">
          {translate("products.fields.id")}
        </Typography>
        {product ? (
          <NumberField value={product.id} />
        ) : (
          <Skeleton height="20px" width="200px" />
        )}
        <Typography variant="body1" fontWeight="bold">
          {translate("products.fields.name")}
        </Typography>
        {product ? (
          <TextField value={product.name} />
        ) : (
          <Skeleton height="20px" width="200px" />
        )}
        <Typography variant="body1" fontWeight="bold">
          {translate("products.fields.description")}
        </Typography>
        {product ? (
          <TextField value={product.description} />
        ) : (
          <Skeleton height="20px" width="200px" />
        )}
        <Typography variant="body1" fontWeight="bold">
          {translate("products.fields.price")}
        </Typography>
        {product ? (
          <NumberField value={product.price} />
        ) : (
          <Skeleton height="20px" width="200px" />
        )}
        <Typography variant="body1" fontWeight="bold">
          {translate("products.fields.material")}
        </Typography>
        {product ? (
          <TextField value={product.material} />
        ) : (
          <Skeleton height="20px" width="200px" />
        )}
        <Typography variant="body1" fontWeight="bold">
          {translate("products.fields.category")}
        </Typography>
        {categoryError ? null : categoryLoading ? (
          <Skeleton height="20px" width="200px" />
        ) : (
          <TextField value={categories?.data?.title} />
        )}
      </Stack>
    </Show>
  );
};

### Create/Edit Product Form with Refine and Material UI

Source: https://refine.dev/docs/index

This snippet defines a form for creating or editing product details using Refine's `Edit` component and Material UI's `TextField` and `Autocomplete` components. It handles form state management with `react-hook-form` and includes validation for required fields. The form allows users to input product name, price, material, and select a category.

```tsx
import {
  Controller,
  useFormContext,
} from "react-hook-form";
import {
  Box,
  TextField as MuiTextField,
  Autocomplete as MuiAutocomplete,
} from "@mui/material";

  Edit,
  useTranslate,
  useResource,
  useParsed,
} from "@refinedev/core";
import {
  TextField,
  NumberField,
  Autocomplete,
} from "@refinedev/mui";

export const ProductEdit = () => {
  const translate = useTranslate();
  const { resource, id } = useParsed();
  const { control, formState: { errors } } = useFormContext();

  const { data: productsData } = useResource({
    resource: "products",
    id,
    queryOptions: {
      enabled: id !== undefined,
    },
  });

  const { data: categories } = useResource({
    resource: "categories",
    queryOptions: {
      enabled: id !== undefined,
    },
  });

  const categoryAutocompleteProps = {
    options: categories?.data ?? [],
    loading: !categories,
  };

  return (
    <Edit saveButtonProps={{ size: "large" }}>

          defaultValue={productsData?.category ?? null}
          render={({ field }) => (
            <Autocomplete
              {...categoryAutocompleteProps}
              {...field}
              onChange={(_, value) => {
                field.onChange(value);
              }}
              getOptionLabel={(item) => {
                return (
                  categoryAutocompleteProps?.options?.find(
                    (p) => p?.id?.toString() === item?.id?.toString(),
                  )?.title ?? ""
                );
              }}

export const TOKEN_KEY = "refine-auth";

export const authProvider: AuthProvider = {
  login: async ({ username, email, password }) => {
    if ((username || email) && password) {
      localStorage.setItem(TOKEN_KEY, username);
      return {
        success: true,
        redirectTo: "/",
      };
    }

    return {
      success: false,
      error: {
        name: "LoginError",
        message: "Invalid username or password",
      },
    };
  },
  logout: async () => {
    localStorage.removeItem(TOKEN_KEY);
    return {
      success: true,
      redirectTo: "/login",
    };
  },
  check: async () => {
    const token = localStorage.getItem(TOKEN_KEY);
    if (token) {
      return {
        authenticated: true,
      };
    }

    return {
      authenticated: false,
      redirectTo: "/login",
    };
  },
  getPermissions: async () => null,
  getIdentity: async () => {
    const token = localStorage.getItem(TOKEN_KEY);

### Category Show Component using Refine

Source: https://refine.dev/docs/index

Displays the details of a single category using Refine's Show component. It fetches category data using `useShow` and displays the ID and title. Skeleton loaders are used while the data is loading. It leverages Material UI components for rendering.

```tsx
// file: /pages/categories/show.tsx 
import {
  useShow,
  useTranslate,
} from "@refinedev/core";

import Skeleton from "@mui/material/Skeleton";
import Stack from "@mui/material/Stack";
import Typography from "@mui/material/Typography";

import {
  NumberField,
  Show,
  TextFieldComponent as TextField,
} from "@refinedev/mui";
import type { Category } from "./types";

export const CategoryShow = () => {
  const translate = useTranslate();
  const {
    result: category,
    query: { isLoading },
  } = useShow<Category>();

  return (
    <Show isLoading={isLoading}>
      <Stack gap={1}>
        <Typography variant="body1" fontWeight="bold">
          {translate("categories.fields.id")}
        </Typography>
        {category ? (
          <NumberField value={category?.id ?? ""} />
        ) : (
          <Skeleton height="20px" width="200px" />
        )}
        <Typography variant="body1" fontWeight="bold">
          {translate("categories.fields.title")}
        </Typography>
        {category ? (
          <TextField value={category?.title} />
        ) : (
          <Skeleton height="20px" width="200px" />
        )}
      </Stack>
    </Show>
  );
};

### Configure Authentication Routes with React Router

Source: https://refine.dev/docs/index

This snippet demonstrates how to configure routes for 'forgot-password' and 'update-password' using React Router within a Refine application. It utilizes the AuthPage component, passing a 'type' prop to differentiate authentication flows. No external dependencies are required beyond React Router and Refine.

```javascript
import React from "react";
import {
  BrowserRouter,
  Routes,
  Route,
} from "react-router-dom";

import {
  Refine,
  AuthPage,
  RefineSnackbarProvider,
} from "@pankod/refine-react-router-v6";
import {
  ColorModeContextProvider,
} from "./context/color-mode";

function App() {
  return (
    <BrowserRouter>
      <ColorModeContextProvider>
        <RefineSnackbarProvider>
          <Refine>
            <Routes>
              <Route
                path="/forgot-password"
                element={<AuthPage type="forgotPassword" />} 
              />
              <Route
                path="/update-password"
                element={<AuthPage type="updatePassword" />} 
              />
            </Routes>
          </Refine>
        </RefineSnackbarProvider>
      </ColorModeContextProvider>
    </BrowserRouter>
  );
}

export default App;
```

### Category List Component using Refine and DataGrid

Source: https://refine.dev/docs/index

Renders a list of categories using Refine's List component and Material UI's DataGrid. It defines columns for category title and actions (Show, Edit, Delete buttons). The component utilizes `useTranslate` for localization and `useDataGrid` for data fetching and management.

```tsx
// file: /pages/categories/list.tsx 
import { useMemo } from "react";

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

import { DataGrid, type GridColDef } from "@mui/x-data-grid";
import {
  DeleteButton,
  EditButton,
  List,
  ShowButton,
  useDataGrid,
} from "@refinedev/mui";

export const CategoryList: React.FC = () => {
  const translate = useTranslate();
  const { dataGridProps } = useDataGrid();

  const columns = useMemo<GridColDef[]>(
    () => [
      {
        field: "title",
        flex: 1,
        headerName: translate("categories.fields.title"),
        minWidth: 200,
      },
      {
        field: "actions",
        headerName: translate("table.actions"),
        sortable: false,
        display: "flex",
        renderCell: function render({ row }) {
          return (
            <>
              <ShowButton hideText recordItemId={row.id} />
              <EditButton hideText recordItemId={row.id} />
              <DeleteButton hideText recordItemId={row.id} />
            </>
          );
        },
        align: "center",
        headerAlign: "center",
        minWidth: 80,
      },
    ],
    [translate],
  );

  return (
    <List>
      <DataGrid {...dataGridProps} columns={columns} />
    </List>
  );
};

```

### Product Edit Form Component (TypeScript)

Source: https://refine.dev/docs/index

The `ProductEdit` component is responsible for rendering the form to edit product details. It uses `useForm` from `@refinedev/react-hook-form` for form state management and validation, and `useAutocomplete` for fetching category options. The form includes fields for ID, name, description, price, material, and category, with appropriate validation and UI elements from Material UI and Refine.

```typescript
import {
  type HttpError,
  useTranslate,
} from "@refinedev/core";
import { useForm } from "@refinedev/react-hook-form";
import { Controller } from "react-hook-form";

import { Autocomplete, Box, TextField } from "@mui/material";
import { Edit, useAutocomplete } from "@refinedev/mui";
import type { Product } from "./types";

export const ProductEdit = () => {
  const translate = useTranslate();
  const {
    saveButtonProps,
    refineCore: { query, formLoading },
    register,
    control,
    formState: { errors },
  } = useForm<Product, HttpError, Product>();

  const productsData = query?.data?.data;

  const { autocompleteProps: categoryAutocompleteProps } = useAutocomplete({
    resource: "categories",
    defaultValue: productsData?.category?.id,
  });

  return (
    <Edit isLoading={formLoading} saveButtonProps={saveButtonProps}>
      <Box
        component="form"
        sx={{ display: "flex", flexDirection: "column" }}
        autoComplete="off"
      >

### Refine React Hook Form for Category Creation

Source: https://refine.dev/docs/index

A React component for creating a new category using Refine's useForm hook and Material UI components. It handles form state, validation, and submission, with a single text field for the category title.

```tsx
// file: /pages/categories/create.tsx 
import { type HttpError, useTranslate } from "@refinedev/core";
import { useForm } from "@refinedev/react-hook-form";

import { Box, TextField } from "@mui/material";
import { Create } from "@refinedev/mui";

import type { Category } from "./types";

export const CategoryCreate: React.FC = () => {
  const translate = useTranslate();
  const {
    saveButtonProps,
    refineCore: { formLoading },
    register,
    formState: { errors },
  } = useForm<Category, HttpError, Category>();

  return (
    <Create isLoading={formLoading} saveButtonProps={saveButtonProps}>
      <Box
        component="form"
        sx={{ display: "flex", flexDirection: "column" }}
        autoComplete="off"
      >
        <TextField
          {...register("title", {
            required: translate("form.required"),
          })}
          error={!!errors?.title}
          helperText={<>{errors?.title?.message}</>}
          margin="normal"
          fullWidth
          slotProps={{
            inputLabel: {
              shrink: true,
            },
          }}
          type="text"
          label={translate("categories.fields.title")}
          name="title"
        />
      </Box>
    </Create>
  );
};

```

### Refine React Hook Form for Category Editing

Source: https://refine.dev/docs/index

A React component for editing an existing category using Refine's useForm hook and Material UI components. It mirrors the creation form, providing fields for editing category details.

```tsx
// file: /pages/categories/edit.tsx 
import { type HttpError, useTranslate } from "@refinedev/core";
import { useForm } from "@refinedev/react-hook-form";

import { Box, TextField } from "@mui/material";

### Category Form Fields for Edit/Create

Source: https://refine.dev/docs/index

Defines input fields for category ID and title within a Refine form. The ID field is a number input and is disabled, while the title field is a text input and is required. It uses Material UI's TextField component and Refine's register function for form handling.

```tsx
        autoComplete="off"
      >
        <TextField
          {...register("id", { valueAsNumber: true })}
          margin="normal"
          fullWidth
          slotProps={{
            inputLabel: {
              shrink: true,
            },
          }}
          type="number"
          label={translate("categories.fields.id")}
          name="id"
          disabled
        />
        <TextField
          {...register("title", {
            required: translate("form.required"),
          })}
          error={!!errors?.title}
          helperText={<>{errors?.title?.message}</>}
          margin="normal"
          fullWidth
          slotProps={{
            inputLabel: {
              shrink: true,
            },
          }}
          type="text"
          label={translate("categories.fields.title")}
          name="title"
        />
      </Box>
    </Edit>
  );
};
```

### Category Interface Definition

Source: https://refine.dev/docs/index

Defines the TypeScript interface for a Category object, specifying its properties as 'id' and 'title', both of which are strings. This interface is used for type safety in the application.

```ts
// file: /pages/categories/types.ts 
export interface Category {
  id: string;
  title: string;
}
