Hi @quick691. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To set a context value upon user login in a refine app, you can leverage refine's authentication system and React's Context API. Here's how you can implement this: Using Auth Provider with Context The most effective approach is to use refine's authProvider in combination with React's Context API. When a user logs in, you can update your context with user-specific data. 1. First, create a context provider in your application:

import React, { createContext, useState, useContext } from "react";

// Create your context
export const UserContext = createContext(null);

// Create a provider component
export const UserContextProvider = ({ children }) => {
  const [userData, setUserData] = useState(null);

  return (
    <UserContext.Provider value={{ userData, setUserData }}>
      {children}
    </UserContext.Provider>
  );
};

// Create a hook for easy context consumption
export const useUserContext = () => useContext(UserContext);

import React, { createContext, useState, useContext } from "react";

// Create your context
export const UserContext = createContext(null);

// Create a provider component
export const UserContextProvider = ({ children }) => {
  const [userData, setUserData] = useState(null);

  return (
    <UserContext.Provider value={{ userData, setUserData }}>
      {children}
    </UserContext.Provider>
  );
};

// Create a hook for easy context consumption
export const useUserContext = () => useContext(UserContext);

2. Wrap your application with this provider:

import { Refine } from "@refinedev/core";
import { UserContextProvider } from "./UserContext";

const App = () => {
  return (
    <UserContextProvider>
      <Refine
        authProvider={authProvider}
        // other refine props
      >
        {/* Your app components */}
      </Refine>
    </UserContextProvider>
  );
};

import { Refine } from "@refinedev/core";
import { UserContextProvider } from "./UserContext";

const App = () => {
  return (
    <UserContextProvider>
      <Refine
        authProvider={authProvider}
        // other refine props
      >
        {/* Your app components */}
      </Refine>
    </UserContextProvider>
  );
};

3. Modify your authProvider.login method to update the context:

import { AuthProvider } from "@refinedev/core";
import { useUserContext } from "./UserContext";
export const authProvider: AuthProvider = {
  login: async ({ email, password }) => {
    const { status, data } = await handleLogin(email, password);
    
    if (status === 200) {
      // Store token in localStorage or cookies
      localStorage.setItem("token", data.jwt);
      
      // Set headers for subsequent API requests
      axiosInstance.defaults.headers.common = {
        Authorization: `Bearer ${data.jwt}`,
      };
      
      // Update your context with user data
      // Note: You'll need to access this context using a hook in a component
      
      return {
        success: true,
        redirectTo: "/dashboard",
      };
    } else {
      return {
        success: false,
        error: {
          name: "Login Error",
          message: "Invalid credentials"
        },
      };
    }
  },
  // other auth methods
};

import { AuthProvider } from "@refinedev/core";
import { useUserContext } from "./UserContext";
export const authProvider: AuthProvider = {
  login: async ({ email, password }) => {
    const { status, data } = await handleLogin(email, password);
    
    if (status === 200) {
      // Store token in localStorage or cookies
      localStorage.setItem("token", data.jwt);
      
      // Set headers for subsequent API requests
      axiosInstance.defaults.headers.common = {
        Authorization: `Bearer ${data.jwt}`,
      };
      
      // Update your context with user data
      // Note: You'll need to access this context using a hook in a component
      
      return {
        success: true,
        redirectTo: "/dashboard",
      };
    } else {
      return {
        success: false,
        error: {
          name: "Login Error",
          message: "Invalid credentials"
        },
      };
    }
  },
  // other auth methods
};

4. Since the authProvider is an object and not a component, you can't directly use React hooks inside it. Instead, you can update the context from your login component:

import { useLogin } from "@refinedev/core";
import { useUserContext } from "./UserContext";

export const LoginPage = () => {
  const { mutate: login } = useLogin();
  const { setUserData } = useUserContext();
  
  const handleSubmit = async (formData) => {
    await login(formData, {
      onSuccess: (data) => {
        // Update context with user data
        setUserData(data.user);
      }
    });
  };
  
  // Your login form JSX
};

import { useLogin } from "@refinedev/core";
import { useUserContext } from "./UserContext";

export const LoginPage = () => {
  const { mutate: login } = useLogin();
  const { setUserData } = useUserContext();
  
  const handleSubmit = async (formData) => {
    await login(formData, {
      onSuccess: (data) => {
        // Update context with user data
        setUserData(data.user);
      }
    });
  };
  
  // Your login form JSX
};

This approach is commonly used in refine applications for managing user authentication and context, as mentioned in the documentation on authentication and demonstrated in various examples. For more complex scenarios, you might want to check out refine's customization-login example which provides a complete implementation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai but you can't use useContext outside of a client component

Let me check the knowledge base for you again. One moment! :books: ---------------------- You're absolutely right. When working with Next.js or other frameworks that separate server and client components, you can't use React hooks like useContext in server components. This is a common challenge when integrating Refine with Next.js. Solution for Client/Server Component Architecture Refine provides its features through React context API, as mentioned in the Discord support thread:

"Refine provides features with react context API. you can serve Refine the same way you serve any react app" Discord support thread

Here's how to properly handle this in a Next.js application: 1. Create a Client Component Wrapper Create a client component that wraps your Refine context:

// refine-context.tsx
"use client";

import { Refine } from "@refinedev/core";
import dataProvider from "@refinedev/simple-rest";
import { PropsWithChildren } from "react";

export function RefineContext({ children }: PropsWithChildren) {
  return (
    <Refine
      dataProvider={dataProvider("<https://api.fake-rest.refine.dev">)}
      authProvider={authProvider}
      // other refine props
    >
      {children}
    </Refine>
  );
}

// refine-context.tsx
"use client";

import { Refine } from "@refinedev/core";
import dataProvider from "@refinedev/simple-rest";
import { PropsWithChildren } from "react";

export function RefineContext({ children }: PropsWithChildren) {
  return (
    <Refine
      dataProvider={dataProvider("<https://api.fake-rest.refine.dev">)}
      authProvider={authProvider}
      // other refine props
    >
      {children}
    </Refine>
  );
}

2. Use the Client Component in Your Layout In your layout file, use this client component wrapper:

// app/layout.tsx
import { RefineContext } from "./refine-context";

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <html lang="en">
      <body>
        <RefineContext>{children}</RefineContext>
      </body>
    </html>
  );
}

// app/layout.tsx
import { RefineContext } from "./refine-context";

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <html lang="en">
      <body>
        <RefineContext>{children}</RefineContext>
      </body>
    </html>
  );
}

3. Create Client Components for Pages That Need Context For components that need to access the context (like login pages):

"use client";
import { useLogin } from "@refinedev/core";
export const LoginPage = () => {
  const { mutate: login } = useLogin();
  
  const handleSubmit = async (formData) => {
    await login(formData);
  };
  
  // Your login form JSX
};

"use client";
import { useLogin } from "@refinedev/core";
export const LoginPage = () => {
  const { mutate: login } = useLogin();
  
  const handleSubmit = async (formData) => {
    await login(formData);
  };
  
  // Your login form JSX
};

This approach is demonstrated in Refine's examples for Next.js integration, as shown in the Usage with Existing Projects documentation. For more complex layouts, you can also pass custom components to the ThemedLayoutV2 as shown in this Discord solution:

// For specific layouts like blog posts
import { ThemedLayoutV2 } from "@refinedev/antd";
import { Header } from "@components/header";
import { ThemedSiderV2 } from "@components/layout/sider";

export default async function Layout({ children }: React.PropsWithChildren) {
  // ...authentication checks
  
  return <ThemedLayoutV2 Header={Header} Sider={ThemedSiderV2}>{children}</ThemedLayoutV2>;
}

// For specific layouts like blog posts
import { ThemedLayoutV2 } from "@refinedev/antd";
import { Header } from "@components/header";
import { ThemedSiderV2 } from "@components/layout/sider";

export default async function Layout({ children }: React.PropsWithChildren) {
  // ...authentication checks
  
  return <ThemedLayoutV2 Header={Header} Sider={ThemedSiderV2}>{children}</ThemedLayoutV2>;
}

This pattern ensures that context is only used within client components while still allowing you to structure your application with both server and client components. Would you like more specific guidance on implementing this in your particular application structure? ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
