Migrating Auth Provider from 3.x.x to 4.x.x

Motivation behind the changes​

Our motivation for modifying the authProvider prop in refine v4 was to improve its flexibility and customization options, allowing it to handle a wider range of use cases without becoming overly complicated.

We aimed to create a more standardized interface for the authProvider methods that would improve transparency and enable easier debugging for developers.

Previously, developers were required to resolve the authProvider methods on success and reject them on failure. However, this approach had limitations, as rejected promises are typically associated with errors or unusual scenarios. Some errors, such as incorrect login credentials, aren’t actually considered failures and need to be communicated to the user. This behavior often confused developers and hindered the debugging process.

Now, the authProvider methods always return a resolved promise that includes an object with a success key. This key indicates whether the operation was successful or not, and in case of failure, an optional error key containing an Error object can be used to notify users.

Furthermore, the auth hooks no longer have default redirection paths, which had previously been a source of confusion for some developers. Instead, developers can now have more control over the redirection after a successful operation by adding a redirectTo property to the authProvider methods' return object

Naming changes​

  • The AuthPovider interface was changed to AuthBindings.

    - import { AuthProvider } from "@refinedev/core";
    + import { AuthBindings } from "@refinedev/core";

    - const authProvider: AuthProvider = {/* ... */}
    + const authProvider: AuthBindings = {/* ... */}
  • The getUserIdentity method of the authProvider was changed to getIdentity.

  • The checkError method of the authProviderwas changed to onError.

  • The checkAuth method of the authProvider was changed to check.

    const authProvider = {
    - getUserIdentity,
    + getIdentity,
    - useCheckError,
    + useOnError,
    - checkAuth,
    + check,
    }
  • The useAuthenticated hook was changed to useIsAuthenticated.

    - import { useAuthenticated } from "@refinedev/core";
    + import { useIsAuthenticated } from "@refinedev/core";

Methods​

login​

Promises must now be resolved in all cases when using the login method, with a return type of AuthActionResponse. When resolving the promise, you must always include a success key, and in the case of a failure, an additional error key.

useLogin no longer has default redirection, so you need to add the redirectTo property to the login method's return object.

const authProvider = {
login: async ({ email, password }) => {
const user = mockUsers.find((item) => item.email === email);

if (user) {
localStorage.setItem("auth", JSON.stringify(user));
- return Promise.resolve();
+ return {
+ success: true,
+ redirectTo: "/",
+ };
}

- return Promise.reject();
+ return {
+ success: false,
+ error: {
+ message: "Login Error",
+ name: "Invalid email or password",
+ }
+ };
},
}
type AuthActionResponse = {
success: boolean;
redirectTo?: string;
error?: Error;
[key: string]: unknown;
};

logout​

Promises must now be resolved in all cases when using the logout method, with a return type of AuthActionResponse. When resolving the promise, you must always include a success key, and in the case of a failure, an additional error key.

useLogout no longer has default redirection, so you need to add the redirectTo property to the logout method's return object.

const authProvider = {
logout: async ({ email, password }) => {
localStorage.removeItem("auth");
- return Promise.resolve();
+ return {
+ success: true,
+ redirectTo: "/login",
+ };
},
}
type AuthActionResponse = {
success: boolean;
redirectTo?: string;
error?: Error;
[key: string]: unknown;
};

register​

Promises must now be resolved in all cases when using the register method, with a return type of AuthActionResponse. When resolving the promise, you must always include a success key, and in the case of a failure, an additional error key.

useRegister no longer has default redirection, so you need to add the redirectTo property to the register method's return object.

const authProvider = {
register: async ({ email, password }) => {
const user = mockUsers.find((item) => item.email === email);

if (user) {
- return Promise.reject();
+ return {
+ success: false,
+ error: {
+ name: "Register Error"",
+ message: "User already exists",
+ },
+ };
}

mockUsers.push({ email });

- return Promise.resolve();
+ return {
+ success: true,
+ redirectTo: "/",
+ };
},
}

forgotPassword​

Promises must now be resolved in all cases when using the forgotPassword method, with a return type of AuthActionResponse. When resolving the promise, you must always include a success key, and in the case of a failure, an additional error key.

useForgotPassword no longer has default redirection, so you need to add the redirectTo property to the forgotPassword method's return object.

const authProvider = {
forgotPassword: async ({ password }) => {
// send password reset link to the user's email address here

// if request is successful
- return Promise.resolve();
+ return {
+ success: true,
+ redirectTo: "/login",
+ };

// if request is not successful
- return Promise.reject();
+ return {
+ success: false,
+ error: {
+ name: "Forgot Password Error",
+ message: "Email address does not exist",
+ },
+ };
},
};
type AuthActionResponse = {
success: boolean;
redirectTo?: string;
error?: Error;
[key: string]: unknown;
};

updatePassword​

Promises must now be resolved in all cases when using the updatePassword method, with a return type of AuthActionResponse. When resolving the promise, you must always include a success key, and in the case of a failure, an additional error key.

useUpdatePassword no longer has default redirection, so you need to add the redirectTo property to the updatePassword method's return object.

const authProvider = {
updatePassword: async ({ password }) => {
// update the user's password here

// if request is successful
- return Promise.resolve();
+ return {
+ success: true,
+ redirectTo: "/login",
+ });

// if request is not successful
- return Promise.reject();
+ return {
+ success: false,
+ error: {
+ name: "Forgot Password Error",
+ message: "Email address does not exist",
+ },
+ };
},
};
type AuthActionResponse = {
success: boolean;
redirectTo?: string;
error?: Error;
[key: string]: unknown;
};

check​

The checkAuth method of the authProvider was changed to check. It now requires promises to be resolved in all cases, with a return type of CheckResponse. When resolving the promise, you must always include a success key, and in the case of a failure, an additional error key.

The <Authenticated> component no longer has default redirection, so you need to add the redirectTo property to the check method's return object. The component doesn't call the logout method by default either, and you need to add the logout: true property to the check method's return object.

const authProvider = {
- checkAuth: async () => {
+ check: async () => {
const user = localStorage.getItem("auth");

if (user) {
- return Promise.resolve();
+ return {
+ authenticated: true,
+ };
}

- return Promise.reject();
+ return {
+ authenticated: false,
+ redirectTo: "/login",
+ logout: true,
+ error: {
+ message: "Check failed",
+ name: "User not found",
+ }
+ };
},
};
type CheckResponse = {
authenticated: boolean;
redirectTo?: string;
logout?: boolean;
error?: Error;
};

onError​

The checkError method of the authProvider was changed to onError. It now requires promises to be resolved in all cases, with a return type of OnErrorResponse. When resolving the promise, you must always include a success key, and in the case of a failure, an additional error key.

The useOnError component no longer has default redirection, so you need to add the redirectTo property to the onError method's return object. The component doesn't call the logout method by default either, so you need to add the logout: true property to the onError method's return object.

const authProvider = {
- checkError: async (error) => {
+ onError: async (error) => {
if (error.status === 401 || error.status === 403) {
- return Promise.reject();
+ return {
+ redirectTo: "/login",
+ logout: true,
+ error: error,
+ };
}

- return Promise.reject();
+ return {};
},
};
type OnErrorResponse = {
redirectTo?: string;
logout?: boolean;
error?: Error;
};

getPermissions​

The getPermissions method now requires promises to be resolved in all cases, with a return type of PermissionResponse

const authProvider = {
getPermissions: async () => {
const user = localStorage.getItem("auth");

if (user) {
const { roles } = JSON.parse(user);

return roles;
}

- return Promise.reject();
+ return null;
},
};
type PermissionResponse = unknown;

getIdentity​

authProvider's getUserIdentity method was renamed to getIdentity, which requires promises to be resolved in all cases, with a return type of IdentityResponse

const authProvider: AuthProvider = {
- getUserIdentity: async () => {
+ getIdentity: async () => {
const user = localStorage.getItem("auth");

if (user) {
const { email, roles } = JSON.parse(user);

return { email, roles };
}

- return Promise.reject();
+ return null;
},
};
type IdentityResponse = unknown;

Auth hooks​

CAUTION

If you used codemod for migration, the v3LegacyAuthProviderCompatible: true prop was added to the auth hooks for backward compatibility. You need to remove this prop if you want to upgrade to the new auth provider.

useLogin({
- v3LegacyAuthProviderCompatible: true,
})

Unlike the previous version, refine@4 requires all auth methods to resolve promises. Therefore, if you used auth hooks in your applications before, they need to be updated accordingly.

To better show the differences between the usage of auth hooks between the two versions, let's create two wrapper components that render children according to the authentication status:

Auth Provider v3:

import { useAuthenticated } from "@pankod/refine-core";

export const Authenticated: React.FC = ({ children }) => {
const { isSuccess, isLoading, isError } = useAuthenticated();

if (isLoading) {
return <div>loading...</div>;
}

if (isError) {
return null;
}

if (isSuccess) {
return <>{children}</>;
}

return null;
};

Auth Provider v4:

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

export const Authenticated: React.FC = ({ children }) => {
const { isLoading, data } = useIsAuthenticated();

if (isLoading) {
return <div>loading...</div>;
}

if (data.error) {
return null;
}

if (data.authenticated) {
return <>{children}</>;
}

return null;
};

Though auth hooks should be familiar, they need to updated according to the new system.

Please refer to the hooks documentation for more information.

Backward compatibility​

refine still supports the authProvider@v3 for backward compatibility. We changed its name to legacyAuthProvider and it will be removed in the next major version. If you want to continue using the authProvider@v3 you can use it as legacyAuthProvider in your project.

- import { AuthProvider } from "@refinedev/core";
+ import { LegacyAuthProvider } from "@refinedev/core";

- const authProvider: AuthProvider = {/* ... */}
+ const authProvider: LegacyAuthProvider = {/* ... */}

const App = () => {
return (
<Refine
- authProvider={authProvider}
+ legacyAuthProvider={authProvider}
>
<AppLayout />
</Refine>
);
};

Additionally, you need to add v3LegacyAuthProviderCompatible: true to your auth hooks in order to continue using authProvider@v3 in your project.

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

const login = useLogin({
v3LegacyAuthProviderCompatible: true,
});
