Hi @kamal. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To show a page with public/private data using Remix with authorization, you can leverage the accessControlProvider and authProvider functionalities provided by refine. Here’s a step-by-step guide to achieve this: Step 1: Set Up Access Control Provider First, you need to create an accessControlProvider to manage access control logic. This provider will determine whether a user can access certain resources based on their permissions.

// app/accessControlProvider.ts
export const accessControlProvider = {  
  can: async ({ resource, action, params }) => {  
    if (resource === "posts" && action === "edit") {  
      return {  
        can: false,  
        reason: "Unauthorized",  
      };  
    }  
    return { can: true };  
  },  
};

// app/accessControlProvider.ts
export const accessControlProvider = {  
  can: async ({ resource, action, params }) => {  
    if (resource === "posts" && action === "edit") {  
      return {  
        can: false,  
        reason: "Unauthorized",  
      };  
    }  
    return { can: true };  
  },  
};

Step 2: Create a Protected Route Next, create a protected route that uses the accessControlProvider to check if the user has the necessary permissions to access the data.

// app/routes/_protected.posts._index.tsx
import { useLoaderData } from "@remix-run/react";  
import { json, LoaderFunctionArgs } from "@remix-run/node";  
import dataProvider from "@refinedev/simple-rest";  
  
import { IPost } from "../interfaces";  
import { API_URL } from "~/constants";  
import { accessControlProvider } from "../accessControlProvider";  
  
const PostList: React.FC = () => {  
  const { initialData } = useLoaderData<typeof loader>();  
  
  return <>{/* Render your data here */}</>;  
};  
  
export default PostList;  
  
export async function loader({ request }: LoaderFunctionArgs) {  
  const can = await accessControlProvider.can({  
    resource: "posts",  
    action: "list",  
  });  
  
  if (!can.can) {  
    return json({}, { status: 403 });  
  }  
  
  const data = await dataProvider(API_URL).getList<IPost>({  
    resource: "posts",  
  });  
  
  return json({ initialData: data });  
}

// app/routes/_protected.posts._index.tsx
import { useLoaderData } from "@remix-run/react";  
import { json, LoaderFunctionArgs } from "@remix-run/node";  
import dataProvider from "@refinedev/simple-rest";  
  
import { IPost } from "../interfaces";  
import { API_URL } from "~/constants";  
import { accessControlProvider } from "../accessControlProvider";  
  
const PostList: React.FC = () => {  
  const { initialData } = useLoaderData<typeof loader>();  
  
  return <>{/* Render your data here */}</>;  
};  
  
export default PostList;  
  
export async function loader({ request }: LoaderFunctionArgs) {  
  const can = await accessControlProvider.can({  
    resource: "posts",  
    action: "list",  
  });  
  
  if (!can.can) {  
    return json({}, { status: 403 });  
  }  
  
  const data = await dataProvider(API_URL).getList<IPost>({  
    resource: "posts",  
  });  
  
  return json({ initialData: data });  
}

Step 3: Implement Client-Side Access Control For client-side access control, you can use the CanAccess component from @refinedev/core to protect your pages from unauthorized access.

import { CanAccess } from "@refinedev/core";  
  
export const MyPage = () => (  
  <CanAccess>  
    <div>{/* Your protected content here */}</div>  
  </CanAccess>  
);

import { CanAccess } from "@refinedev/core";  
  
export const MyPage = () => (  
  <CanAccess>  
    <div>{/* Your protected content here */}</div>  
  </CanAccess>  
);

Step 4: Authentication To handle authentication, you can use the Authenticated component from @refinedev/core on the client-side and the authProvider's check function on the server-side. #### Client-Side Authentication

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

export const MyProtectedPage = () => (
  <Authenticated>
    <div>{/* Your protected content here */}</div>
  </Authenticated>
);

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

export const MyProtectedPage = () => (
  <Authenticated>
    <div>{/* Your protected content here */}</div>
  </Authenticated>
);

#### Server-Side Authentication

import { redirect } from "@remix-run/node";
import { authProvider } from "./authProvider";

export async function loader({ request }: LoaderFunctionArgs) {
  const isAuthenticated = await authProvider.check(request);

  if (!isAuthenticated) {
    return redirect("/login");
  }

  // Your data fetching logic here
}

import { redirect } from "@remix-run/node";
import { authProvider } from "./authProvider";

export async function loader({ request }: LoaderFunctionArgs) {
  const isAuthenticated = await authProvider.check(request);

  if (!isAuthenticated) {
    return redirect("/login");
  }

  // Your data fetching logic here
}
