avoid the need for useGetIdentity

My identity is not changing from page to page, we have our usernmae and profile avatar on the top bar, is there anyway of getting this information without querying moving from page to page I am trying reduce the amount of queries is there a way of getting the logged in user data with out querying with useGetIdentity and without session storage

Hi @koop_g. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the knowledge sources provided, there isn't a direct way to avoid using useGetIdentity or session storage while still getting the logged-in user data without querying. However, I can suggest a couple of approaches that might help reduce the number of queries: 1. Use React Context: You could set up a React Context to store the user identity information after the initial fetch. This way, you'd only need to call useGetIdentity once at the top level of your application, and then use the context in child components. 2. Caching with react-query: The useGetIdentity hook is built on top of react-query, which has built-in caching mechanisms. You can configure the caching behavior to reduce the number of actual API calls made. Here's how you might implement the React Context approach:

import React, { createContext, useContext, useEffect, useState } from 'react';
import { useGetIdentity } from "@refinedev/core";

const UserContext = createContext(null);

export const UserProvider = ({ children }) => {
  const { data: user } = useGetIdentity();
  const [userData, setUserData] = useState(null);

  useEffect(() => {
    if (user) {
      setUserData(user);
    }
  }, [user]);

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

export const useUser = () => useContext(UserContext);

import React, { createContext, useContext, useEffect, useState } from 'react';
import { useGetIdentity } from "@refinedev/core";

const UserContext = createContext(null);

export const UserProvider = ({ children }) => {
  const { data: user } = useGetIdentity();
  const [userData, setUserData] = useState(null);

  useEffect(() => {
    if (user) {
      setUserData(user);
    }
  }, [user]);

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

export const useUser = () => useContext(UserContext);

Then, in your App.tsx or top-level component:

import { UserProvider } from './UserContext';

const App = () => {
  return (
    <RefineProvider ...>
      <UserProvider>
        {/* Your app components */}
      </UserProvider>
    </RefineProvider>
  );
};

import { UserProvider } from './UserContext';

const App = () => {
  return (
    <RefineProvider ...>
      <UserProvider>
        {/* Your app components */}
      </UserProvider>
    </RefineProvider>
  );
};

Now, in any component where you need the user data:

import { useUser } from './UserContext';

const TopBar = () => {
  const user = useUser();
return (
    <div>
      <span>{user?.name}</span>
      <img src={user?.avatar} alt="User avatar" />
    </div>
  );
};

import { useUser } from './UserContext';

const TopBar = () => {
  const user = useUser();
return (
    <div>
      <span>{user?.name}</span>
      <img src={user?.avatar} alt="User avatar" />
    </div>
  );
};

This approach will still use useGetIdentity once, but it won't query on every page navigation. The user data will be stored in the React Context and available throughout your application without additional queries. It's worth noting that this approach assumes that the user identity doesn't change during the session. If there's a possibility of the user data changing (e.g., profile updates), you might need to implement a way to refresh the context data. For more information on useGetIdentity, you can refer to the useGetIdentity documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize, but I don't have enough information in the provided knowledge sources to directly address the specific error you're encountering. However, I can provide some general guidance based on the error message you've shared. The error message suggests there's a syntax issue in your TypeScript code, specifically in the file /client/src/contexts.ts on line 19. The error is pointing to the value prop of the UserContext.Provider. This type of error often occurs when TypeScript is expecting a certain type for a prop but receives a different one. In this case, it seems that TypeScript is having trouble with the type of userData being passed as the value prop. To resolve this, you might need to: 1. Ensure that the type of userData matches what UserContext.Provider expects. 2. If UserContext was created with a specific type, make sure userData conforms to that type. 3. You might need to add type annotations or use type assertions if TypeScript can't infer the correct types. Here's an example of how you might modify the code to address this:

import React, { createContext, useContext, useEffect, useState } from 'react';
import { useGetIdentity } from "@refinedev/core";

// Define the shape of your user data
interface UserData {
  // Add appropriate fields here
  name?: string;
  avatar?: string;
  // ... other fields
}

const UserContext = createContext<UserData | null>(null);

export const UserProvider: React.FC = ({ children }) => {
  const { data: user } = useGetIdentity<UserData>();
  const [userData, setUserData] = useState<UserData | null>(null);

  useEffect(() => {
    if (user) {
      setUserData(user);
    }
  }, [user]);

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

export const useUser = () => useContext(UserContext);

import React, { createContext, useContext, useEffect, useState } from 'react';
import { useGetIdentity } from "@refinedev/core";

// Define the shape of your user data
interface UserData {
  // Add appropriate fields here
  name?: string;
  avatar?: string;
  // ... other fields
}

const UserContext = createContext<UserData | null>(null);

export const UserProvider: React.FC = ({ children }) => {
  const { data: user } = useGetIdentity<UserData>();
  const [userData, setUserData] = useState<UserData | null>(null);

  useEffect(() => {
    if (user) {
      setUserData(user);
    }
  }, [user]);

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

export const useUser = () => useContext(UserContext);

This example adds type annotations that should help TypeScript understand the types involved. However, without seeing more of your code or the exact definition of UserContext, I can't provide a more specific solution. If you continue to face issues, you might want to check the React Context documentation for more information on how to properly type your context in TypeScript. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
