AuthProvider triggeres many times getIdentity()

Hello, i'm using Strapi as my backend and I get a lots of API calls that uses method getIdentity() from authProvider.

 getIdentity: async () => {
    const token = localStorage.getItem(TOKEN_KEY);
    if (!token) {
      return null;
    }

    const { data, status } = await strapiAuthHelper.me(token, {
      meta: {
        populate: "*",
      },
    });
    if (status === 200) {
      // console.log(data);
      const { id, username, email, name, avatar, role } = data;
      return {
        id,
        username: username,
        name: name,
        email,
        avatar,
        role,
      };
    }

    return null;
  },

 getIdentity: async () => {
    const token = localStorage.getItem(TOKEN_KEY);
    if (!token) {
      return null;
    }

    const { data, status } = await strapiAuthHelper.me(token, {
      meta: {
        populate: "*",
      },
    });
    if (status === 200) {
      // console.log(data);
      const { id, username, email, name, avatar, role } = data;
      return {
        id,
        username: username,
        name: name,
        email,
        avatar,
        role,
      };
    }

    return null;
  },

How to fix it?

Hi @sensib0i. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The getIdentity method in your authProvider is used to get the user's identity. It's called under the hood by the useGetIdentity hook provided by refine. This method is expected to return a resolved promise with the user's identity. In your case, you're using Strapi as your backend and you're fetching the user's identity using the me method from strapiAuthHelper. If the status of the response is 200, you're returning the user's identity. If you're experiencing issues with this method, here are a few things you could check: 1. Ensure that the TOKEN_KEY is correctly set in the local storage and it's the correct key for your application. 2. Check if the strapiAuthHelper.me method is correctly implemented and it's returning the expected data. 3. Make sure that the status of the response is correctly checked. If the status is not 200, the method will return null which might not be the expected behavior in your application. 4. Check if the user's data (id, username, email, name, avatar, role) exists in the data object of the response. Here's an example of how getIdentity method is implemented in the extracts:

getIdentity: async () => {
  const token = localStorage.getItem(TOKEN_KEY);
  if (!token) {
    return null;
  }

  const { data, status } = await strapiAuthHelper.me(token);
  if (status === 200) {
    const { id, username, email } = data;
    return {
      id,
      name: username,
      email,
    };
  }

  return null;
},

getIdentity: async () => {
  const token = localStorage.getItem(TOKEN_KEY);
  if (!token) {
    return null;
  }

  const { data, status } = await strapiAuthHelper.me(token);
  if (status === 200) {
    const { id, username, email } = data;
    return {
      id,
      name: username,
      email,
    };
  }

  return null;
},

In this example, the getIdentity method is fetching the user's identity from Strapi using the me method from strapiAuthHelper and it's returning the user's id, name, and email if the status of the response is 200.

@kapa.ai I mean it works but I it sends multiple API requests each time that shoul be triggered. Is it good? @kapa.ai u here?

@kapa.ai I mean it works but I it sends multiple API requests for the same method

kapa.ai•13mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The getIdentity method is called whenever the useGetIdentity hook is used in your application. If you're seeing multiple API requests for the same method, it's likely that the useGetIdentity hook is being called multiple times. Here are a few things you could check: 1. Check where the useGetIdentity hook is used: If it's used in multiple components that are rendered at the same time, it will result in multiple API calls. Try to limit the usage of this hook to the necessary components only. 2. Check for unnecessary re-renders: If the component using the useGetIdentity hook is re-rendering multiple times, it will result in multiple API calls. Try to optimize your component to avoid unnecessary re-renders. 3. Use a state management solution: If the user's identity is needed in multiple parts of your application, consider storing it in a global state using a state management library like Redux or MobX. This way, you can fetch the user's identity once and access it from anywhere in your application without making additional API calls. Remember that useGetIdentity hook returns the result of react-query's useQuery which includes properties like isSuccess and isError. You can use these properties to handle loading and error states in your application and avoid unnecessary API calls. Here's an example of how you can use the useGetIdentity hook:

import { useGetIdentity } from "@refinedev/core";  
  
export const User: React.FC = () => {  
 const { data: identity } = useGetIdentity<{  
 id: number;  
 fullName: string;  
 }>();  
  
 return <span>{identity?.fullName}</span>;  
};

import { useGetIdentity } from "@refinedev/core";  
  
export const User: React.FC = () => {  
 const { data: identity } = useGetIdentity<{  
 id: number;  
 fullName: string;  
 }>();  
  
 return <span>{identity?.fullName}</span>;  
};

In this example, the useGetIdentity hook is used to fetch the user's identity and display the user's full name.

@kapa.ai Ok the problem was here const accessControlProvider: IAccessControlContext = { can: async ({ resource, action, params }) => { // @ts-ignore // TODO: naprawić ten leak here // const user = await authProvider?.getIdentity(params); // console.log(user); } } how should i use that accessControlProvider?

kapa.ai•13mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The accessControlProvider is used to manage access control throughout your application. It should have a single asynchronous method named can which is used to check if a desired access will be granted. Here's an example of how you can use the accessControlProvider:

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

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

In this example, the can function checks if the resource is "posts" and the action is "edit". If both conditions are met, it returns { can: false, reason: "Unauthorized" }, otherwise, it returns { can: true }. You can also access the resource object directly:

const resourceName = params?.resource?.name;  
const anyUsefulMeta = params?.resource?.meta?.yourUsefulMeta;  
  
export const accessControlProvider = {  
 can: async ({ resource, action, params }) => {  
 if (  
 resourceName === "posts" &&  
 anyUsefulMeta === true &&  
 action === "edit"  
 ) {  
 return {  
 can: false,  
 reason: "Unauthorized",  
 };  
 }  
 },  
};

const resourceName = params?.resource?.name;  
const anyUsefulMeta = params?.resource?.meta?.yourUsefulMeta;  
  
export const accessControlProvider = {  
 can: async ({ resource, action, params }) => {  
 if (  
 resourceName === "posts" &&  
 anyUsefulMeta === true &&  
 action === "edit"  
 ) {  
 return {  
 can: false,  
 reason: "Unauthorized",  
 };  
 }  
 },  
};

In this example, the can function checks if the resourceName is "posts", anyUsefulMeta is true, and the action is "edit". If all conditions are met, it returns { can: false, reason: "Unauthorized" }. You can then provide the accessControlProvider to the <Refine> component:

const App: React.FC = () => {  
 return (  
 <Refine  
 // other providers and props  
 accessControlProvider={accessControlProvider}  
 >  
 {/* your app */}  
 </Refine>  
 );  
};

const App: React.FC = () => {  
 return (  
 <Refine  
 // other providers and props  
 accessControlProvider={accessControlProvider}  
 >  
 {/* your app */}  
 </Refine>  
 );  
};

@kapa.ai i want to set it depending on User role, how to do that? to not have leak?

kapa.ai•13mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To set the accessControlProvider depending on the user role, you need to fetch the user's role inside the can method. You can use the authProvider's getPermissions method to get the user's role. However, you should be careful to avoid memory leaks. Here's an example of how you can do this:

export const accessControlProvider = {  
 can: async ({ resource, action }: CanParams): Promise<CanReturnType> => {  
 const role = await authProvider.getPermissions();  
  
 if (role === 'admin') {
   // Admin can do everything
   return Promise.resolve({ can: true });
 }

 if (role === 'editor' && resource === 'posts' && action === 'edit') {
   // Editor can only edit posts
   return Promise.resolve({ can: true });
 }

 // Other users can't do anything
 return Promise.resolve({ can: false, reason: 'Unauthorized' });
 }  
};

export const accessControlProvider = {  
 can: async ({ resource, action }: CanParams): Promise<CanReturnType> => {  
 const role = await authProvider.getPermissions();  
  
 if (role === 'admin') {
   // Admin can do everything
   return Promise.resolve({ can: true });
 }

 if (role === 'editor' && resource === 'posts' && action === 'edit') {
   // Editor can only edit posts
   return Promise.resolve({ can: true });
 }

 // Other users can't do anything
 return Promise.resolve({ can: false, reason: 'Unauthorized' });
 }  
};

In this example, the can function fetches the user's role using authProvider.getPermissions(). If the user's role is 'admin', it allows all actions. If the user's role is 'editor' and the resource is 'posts' and the action is 'edit', it allows the action. For all other cases, it denies the action. Remember to replace 'admin' and 'editor' with the actual roles in your application.

if someone has similar problem: the error was actually caused by accessControlProvider i had a leak over there

const accessControlProvider: IAccessControlContext = {
  can: async ({ resource, action, params }) => {
    // @ts-ignore
    const user = await authProvider?.getPermissions(); // leak here
  }
...rest-of-code
}

const accessControlProvider: IAccessControlContext = {
  can: async ({ resource, action, params }) => {
    // @ts-ignore
    const user = await authProvider?.getPermissions(); // leak here
  }
...rest-of-code
}
