How do I access i18n keys in auth provider?

I am trying to use my i18n keys inside my auth provider but can't figure out how to do this. I can't use 'useTranslate()' hook due to this not being a react component, how else can I access it?

Hi @Chrystian Ferreira. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To use i18n keys inside your auth provider, you can't directly use the useTranslate() hook as it's not a React component. However, you can create an i18nProvider and use the translate method from it. Here's how you can create an i18nProvider:

import type { I18nProvider } from "@refinedev/core";  
import { Refine } from "@refinedev/core";  
import { useTranslation } from "react-i18next";  
  
const App: React.FC = () => {  
 const { t, i18n } = useTranslation();  
  
 const i18nProvider: I18nProvider = {  
 translate: (key: string, options?: any) => t(key, options),  
 changeLocale: (lang: string) => i18n.changeLanguage(lang),  
 getLocale: () => i18n.language,  
 };  
  
 return (  
 <Refine  
 i18nProvider={i18nProvider}  
 /* ... */  
 >  
 {/* ... */}  
 </Refine>  
 );  
};

import type { I18nProvider } from "@refinedev/core";  
import { Refine } from "@refinedev/core";  
import { useTranslation } from "react-i18next";  
  
const App: React.FC = () => {  
 const { t, i18n } = useTranslation();  
  
 const i18nProvider: I18nProvider = {  
 translate: (key: string, options?: any) => t(key, options),  
 changeLocale: (lang: string) => i18n.changeLanguage(lang),  
 getLocale: () => i18n.language,  
 };  
  
 return (  
 <Refine  
 i18nProvider={i18nProvider}  
 /* ... */  
 >  
 {/* ... */}  
 </Refine>  
 );  
};

(Source: Creating the i18n Provider (https://refine.dev/docs/guides-concepts/i18n#creating-the-i18n-provider)) The translate method from i18nProvider can be used to translate the keys. It takes parameters and passes them to the provided i18nProvider and expects a string as a return value.

const i18nProvider: I18nProvider = {  
 translate: (key: string, options?: any, defaultMessage?: string) => t(key, defaultMessage, options),  
 // ...  
};

const i18nProvider: I18nProvider = {  
 translate: (key: string, options?: any, defaultMessage?: string) => t(key, defaultMessage, options),  
 // ...  
};

(Source: Translate Method (https://refine.dev/docs/i18n/i18n-provider#translate)) You can use this translate method in your auth provider to translate your custom notifications. However, the exact implementation would depend on how your auth provider is set up. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai How exactly do I access the i18nProvider inside the authProvider?

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- I'm sorry for the confusion, but based on the information provided in the extracts, there's no direct way to access the i18nProvider inside the authProvider. The authProvider and i18nProvider are both properties of the <Refine> component and are used independently within the Refine framework. The authProvider is responsible for handling authentication logic, while the i18nProvider is used for localization features. They don't have a built-in way to interact with each other directly. If you need to use translated messages within your authProvider, you might need to handle this outside of the authProvider and pass the translated messages as parameters to your authProvider methods. However, this would depend on the specific requirements of your application and how you've structured your code. For more detailed information, you can refer to the Refine documentation (https://refine.dev/docs). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Here's my authProvider login function:

  login: async ({ document, password, remember }) => {
    let user;
    let token;
    try {
      const { userInformation, userToken } =
        await apiAuthProvider.getUserInformation({
          document,
          password,
        });
      user = userInformation;
      token = userToken;
    } catch (error) {
      return {
        success: false,
        error: {
          name: "LoginError",
          message: "Erro ao realizar login. Contate um administrador.", // Need to use i18n here
        },
      };
    }

    if (user) {
      nookies.set(
        null,
        "auth",
        JSON.stringify({ ...user, token, roles: ["distributor"] }),
        {
          maxAge: 30 * 24 * 60 * 60,
          path: "/",
        }
      );
      return {
        success: true,
        redirectTo: "/",
      };
    }

  login: async ({ document, password, remember }) => {
    let user;
    let token;
    try {
      const { userInformation, userToken } =
        await apiAuthProvider.getUserInformation({
          document,
          password,
        });
      user = userInformation;
      token = userToken;
    } catch (error) {
      return {
        success: false,
        error: {
          name: "LoginError",
          message: "Erro ao realizar login. Contate um administrador.", // Need to use i18n here
        },
      };
    }

    if (user) {
      nookies.set(
        null,
        "auth",
        JSON.stringify({ ...user, token, roles: ["distributor"] }),
        {
          maxAge: 30 * 24 * 60 * 60,
          path: "/",
        }
      );
      return {
        success: true,
        redirectTo: "/",
      };
    }

Is there any way to use the next-i18next library to do this? @kapa.ai

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you can use the next-i18next library to handle translations in your authProvider. However, you'll need to use the server-side translation function since hooks are not available outside of React components. Here's an example of how you can do this: First, you need to set up your next-i18next configuration. You can follow the guide in the Next.js example (https://refine.dev/docs/examples/i18n/i18n-nextjs) in the Refine documentation. Then, you can import the serverSideTranslations function from next-i18next/serverSideTranslations in your page component and use it to get the translations you need. Here's an example:

import { serverSideTranslations } from 'next-i18next/serverSideTranslations'

export async function getServerSideProps({ locale }) {
  return {
    props: {
      ...await serverSideTranslations(locale, ['common', 'footer']),
      // Will be passed to the page component as props
    },
  }
}

import { serverSideTranslations } from 'next-i18next/serverSideTranslations'

export async function getServerSideProps({ locale }) {
  return {
    props: {
      ...await serverSideTranslations(locale, ['common', 'footer']),
      // Will be passed to the page component as props
    },
  }
}

In your authProvider, you can then use these translations:

login: async ({ document, password, remember, t }) => {
  let user;
  let token;
  try {
    const { userInformation, userToken } =
      await apiAuthProvider.getUserInformation({
        document,
        password,
      });
    user = userInformation;
    token = userToken;
  } catch (error) {
    return {
      success: false,
      error: {
        name: "LoginError",
        message: t('loginError'), // Use the translation function here
      },
    };
  }

  // Rest of your code...
}

login: async ({ document, password, remember, t }) => {
  let user;
  let token;
  try {
    const { userInformation, userToken } =
      await apiAuthProvider.getUserInformation({
        document,
        password,
      });
    user = userInformation;
    token = userToken;
  } catch (error) {
    return {
      success: false,
      error: {
        name: "LoginError",
        message: t('loginError'), // Use the translation function here
      },
    };
  }

  // Rest of your code...
}

In this example, t is the translation function that you get from serverSideTranslations. You would need to pass it to your authProvider when you call it. Please note that this is a general guide and you might need to adjust the code to fit your specific use case. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Is this really the only way? Do I need to pass a function to my authProvider if I want to access my translations? I may be wrong, but this doesn't feel like a good solution. Can anyone help me with this?
