usePermissions

usePermissions calls the getPermissions method from the authProvider under the hood.

It returns the result of react-query's useQuery which includes many properties, some of which being isSuccess and isError.

Data that is resolved from the getPermissions will be returned as the data in the query result.

Usage​

usePermissions can be useful when you want to get user's permission's anywhere in your code.

For example, if you want only the users with the admin role to see the create button in a list page, we have a logic in authProvider's getPermissions method like below:

import type { AuthBindings } from "@refinedev/core";

const authProvider: AuthBindings = {
  ...
    getPermissions: async () => {
        return ["admin"];
    },
  ...
};

Get permissions data in the list page with usePermissions and check if the user has "admin" role:

import { usePermissions } from "@refinedev/core";
import { List } from "@refinedev/antd";

export const PostList: React.FC = () => {
    const { data: permissionsData } = usePermissions();

    return <List canCreate={permissionsData?.includes("admin")}>...</List>;
};
