next js

@kapa.ai Hi This code is for auth-provider in a nextjs refinedev app. I encounter the following error :Unhandled Runtime Error Error: Functions cannot be passed directly to Client Components unless you explicitly expose it by marking it with "use server". Or maybe you meant to call this function rather than return it. {login: function login, register: ..., logout: ..., onError: ..., check: ..., getIdentity: ...} Can you help, Please?

Hi @alex. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To resolve the error "Functions cannot be passed directly to Client Components unless you explicitly expose it by marking it with 'use server'", you need to ensure that your providers are correctly separated and marked for client or server usage. This is a common issue when using Next.js with Refine, especially when dealing with authentication providers. Here's a step-by-step guide to help you fix this issue: 1. Separate Client and Server Providers: Create separate files for your client and server providers. This ensures that functions are correctly marked and used in the appropriate context. 2. Mark Functions Appropriately: Use the use client or use server directive to mark your functions. 3. Use the Correct Provider in Your Components: Ensure that you are using the correct provider in your server and client components. Here is an example structure and code to help you set this up: Directory Structure

src/
  app/
    layout.tsx
    page.tsx
  providers/
    auth-provider/
      auth-provider.client.tsx
      auth-provider.server.tsx

src/
  app/
    layout.tsx
    page.tsx
  providers/
    auth-provider/
      auth-provider.client.tsx
      auth-provider.server.tsx

auth-provider.client.tsx

'use client';

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

export const authProvider: AuthProvider = {
  login: async ({ email, password }) => {
    const { status } = handleLogin(email, password);

    if (status === 200) {
      return { success: true, redirectTo: "/dashboard" };
    } else {
      return {
        success: false,
        error: { name: "Login Error", message: "Invalid credentials" },
      };
    }
  },
  check: async (params) => ({}),
  logout: async (params) => ({}),
  onError: async (params) => ({}),
  register: async (params) => ({}),
  forgotPassword: async (params) => ({}),
  updatePassword: async (params) => ({}),
  getPermissions: async (params) => ({}),
  getIdentity: async (params) => ({}),
};

'use client';

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

export const authProvider: AuthProvider = {
  login: async ({ email, password }) => {
    const { status } = handleLogin(email, password);

    if (status === 200) {
      return { success: true, redirectTo: "/dashboard" };
    } else {
      return {
        success: false,
        error: { name: "Login Error", message: "Invalid credentials" },
      };
    }
  },
  check: async (params) => ({}),
  logout: async (params) => ({}),
  onError: async (params) => ({}),
  register: async (params) => ({}),
  forgotPassword: async (params) => ({}),
  updatePassword: async (params) => ({}),
  getPermissions: async (params) => ({}),
  getIdentity: async (params) => ({}),
};

auth-provider.server.tsx

'use server';

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

export const authProvider: AuthProvider = {
  check: async (params) => {
    // Server-side check logic
  },
  // Other server-side methods
};

'use server';

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

export const authProvider: AuthProvider = {
  check: async (params) => {
    // Server-side check logic
  },
  // Other server-side methods
};

Using the Providers in Your Components In your Next.js components, you can now import and use the appropriate provider based on whether the component is a server or client component. Example Component

import { authProvider } from "@providers/auth-provider/auth-provider.client"; // or auth-provider.server

const App = () => {
  return <Refine authProvider={authProvider}>...</Refine>;
};

export default App;

import { authProvider } from "@providers/auth-provider/auth-provider.client"; // or auth-provider.server

const App = () => {
  return <Refine authProvider={authProvider}>...</Refine>;
};

export default App;

By following these steps, you should be able to resolve the error and correctly use your auth provider in both server and client components. For more detailed information, you can refer to the Refine documentation on using providers in both server and client components (https://refine.dev/docs/routing/integrations/next-js/#how-can-i-use-my-providers-in-the-both-server-and-client-side). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai here is the auth-provider.server.ts code:import type { AuthProvider } from "@refinedev/core"; import { cookies } from "next/headers"; export const authProviderServer: Pick<AuthProvider, "check"> = { check: async () => { const cookieStore = cookies(); const auth = cookieStore.get("auth"); if (auth) { return { authenticated: true, }; } return { authenticated: false, logout: true, redirectTo: "/login", }; }, };
