Translate errors inside authProvider

I have error handling in the authProvider and I would like to allow errors to be translated.

Hi @BlackBearFTW. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To allow errors to be translated inside the authProvider, you can customize the error message returned by the authProvider methods. This can be done by resolving the Promise with an error object that has name and message properties. Here's an example of how you can customize the error message in the login method:

import { AuthProvider } from "@refinedev/core";  
  
const authProvider: AuthProvider = {  
 login: async ({ email, password }) => {  
 // ---  
 return {  
 success: false,  
 error: {  
 name: "Login Failed!",  
 message: "The email or password that you've entered doesn't match any account.",  
 },  
 };  
 },  
 // ---  
};

import { AuthProvider } from "@refinedev/core";  
  
const authProvider: AuthProvider = {  
 login: async ({ email, password }) => {  
 // ---  
 return {  
 success: false,  
 error: {  
 name: "Login Failed!",  
 message: "The email or password that you've entered doesn't match any account.",  
 },  
 };  
 },  
 // ---  
};

In this example, the name and message properties of the error object are set to custom strings. You can replace these strings with translated versions as needed. This approach can be applied to other methods of the authProvider as well, such as register and updatePassword. For more information, refer to the following documentation pages: - Login (https://refine.dev/docs/authentication/auth-provider#login) - Register (https://refine.dev/docs/authentication/auth-provider#register) - Update Password (https://refine.dev/docs/authentication/auth-provider#updatepassword) ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I want to use i18n

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To use internationalization (i18n) in your Refine application, you can use any i18n library you want, but you need to create an i18nProvider based on the chosen library. Here's a basic example of how to create an i18nProvider with react-i18next:

import { I18nProvider } from "@refinedev/core";  
import { useTranslation } from "react-i18next";

const { t, i18n } = useTranslation();

const i18nProvider: I18nProvider = {
    translate: (key: string, params: object) => {
        return t(key, params);
    },
    changeLocale: (lang: string) => i18n.changeLanguage(lang),
    getLocale: () => i18n.language,
};

import { I18nProvider } from "@refinedev/core";  
import { useTranslation } from "react-i18next";

const { t, i18n } = useTranslation();

const i18nProvider: I18nProvider = {
    translate: (key: string, params: object) => {
        return t(key, params);
    },
    changeLocale: (lang: string) => i18n.changeLanguage(lang),
    getLocale: () => i18n.language,
};

After creating the i18nProvider, you can pass it to the <Refine /> component:

import { Refine } from "@refinedev/core";  
import i18nProvider from "./i18nProvider";  

const App: React.FC = () => {  
    return (  
        <Refine  
            i18nProvider={i18nProvider}  
            /* ... */  
        >  
            {/* ... */}  
        </Refine>  
    );  
};

import { Refine } from "@refinedev/core";  
import i18nProvider from "./i18nProvider";  

const App: React.FC = () => {  
    return (  
        <Refine  
            i18nProvider={i18nProvider}  
            /* ... */  
        >  
            {/* ... */}  
        </Refine>  
    );  
};

You can then use the useTranslate, useSetLocale, and useGetLocale hooks to handle i18n in your components:

import { useTranslate, useSetLocale, useGetLocale } from "@refinedev/core";  

export const MyPage = () => {  
    const translate = useTranslate();  
    const setLocale = useSetLocale();  
    const getLocale = useGetLocale();  

    return (  
        <>  
            Current Locale: {getLocale()}  
            <Button onClick={() => setLocale("en")}>Set Locale to English</Button>  
            <Button onClick={() => setLocale("de")}>Set Locale to German</Button>  
            <Button>{translate("Hello")}</Button>  
        </>  
    );  
};

import { useTranslate, useSetLocale, useGetLocale } from "@refinedev/core";  

export const MyPage = () => {  
    const translate = useTranslate();  
    const setLocale = useSetLocale();  
    const getLocale = useGetLocale();  

    return (  
        <>  
            Current Locale: {getLocale()}  
            <Button onClick={() => setLocale("en")}>Set Locale to English</Button>  
            <Button onClick={() => setLocale("de")}>Set Locale to German</Button>  
            <Button>{translate("Hello")}</Button>  
        </>  
    );  
};

For more information, refer to the Refine i18n Provider documentation (https://refine.dev/docs/i18n/i18n-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how can I How can I debug the check function inside authProvider?

kapa.ai•2y ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Debugging the check function inside authProvider can be done using console.log or a debugger like Chrome DevTools. Here's an example of how you can add console.log to the check method:

import { AuthProvider } from "@refinedev/core";  
  
export const authProvider: AuthProvider = {  
 check: async () => {  
 const isAuthenticated = myCheckLogic();  
  
 console.log('Is Authenticated:', isAuthenticated); // Debugging line

 if (isAuthenticated) {  
 return { authenticated: true };  
 }  
  
 return {  
 authenticated: false,  
 redirectTo: "/my-login-page",  
 error: {  
 name: "Authentication Failed.",  
 message: "User not found.",  
 },  
 };  
 },  
 // Other methods...
};

import { AuthProvider } from "@refinedev/core";  
  
export const authProvider: AuthProvider = {  
 check: async () => {  
 const isAuthenticated = myCheckLogic();  
  
 console.log('Is Authenticated:', isAuthenticated); // Debugging line

 if (isAuthenticated) {  
 return { authenticated: true };  
 }  
  
 return {  
 authenticated: false,  
 redirectTo: "/my-login-page",  
 error: {  
 name: "Authentication Failed.",  
 message: "User not found.",  
 },  
 };  
 },  
 // Other methods...
};

In this example, console.log is used to print the value of isAuthenticated to the console. This can help you understand the state of your application at the time the check method is called. If you're using a tool like Chrome DevTools, you can add a breakpoint inside the check method to pause execution of your application at that point. This allows you to inspect the values of variables and the call stack. For more information on debugging in JavaScript, you can refer to the Chrome DevTools documentation (https://developer.chrome.com/docs/devtools/javascript/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
