Set a context upon user Login
How to fix a context value upon user Login in a refine app ?
KHi @quick691. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. 
K----------------------
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:
The most effective approach is to use refine's
import { AuthProvider } from "@refinedev/core";
import { useUserContext } from "./UserContext";
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- First, create a context provider in your application:
- Wrap your application with this provider:
- Modify your method to update the context:
import { AuthProvider } from "@refinedev/core";
import { useUserContext } from "./UserContext";
Kexport 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:
};
// 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
};
tsx
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.
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
};
tsx
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
};
```

M@kapa.ai but you can't use useContext outside of a client component
KLet me check the knowledge base for you again. One moment!

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 in server components. This is a common challenge when integrating Refine with Next.js.
Refine provides its features through React context API, as mentioned in the Discord support thread:
Here's how to properly handle this in a Next.js application:
Create a client component that wraps your Refine context:
In your layout file, use this client component wrapper:
For components that need to access the context (like login pages):
```tsx
"use client";
import { useLogin } from "@refinedev/core";

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" ask-any-questionHow to serve refine app using Next.js Custom Server?
Here's how to properly handle this in a Next.js application:
- Create a Client Component Wrapper
Create a client component that wraps your Refine context:
- Use the Client Component in Your Layout
In your layout file, use this client component wrapper:
- Create Client Components for Pages That Need Context
For components that need to access the context (like login pages):
```tsx
"use client";
import { useLogin } from "@refinedev/core";
Kexport const LoginPage = () => {
const { mutate: login } = useLogin();
const handleSubmit = async (formData) => {
await login(formData);
};
// Your login form JSX
};
tsx
// 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?
