Using translations

Makerkit uses the library i18next for translations, but it's abstracted behind the @kit/i18n package. This abstraction ensures that any future changes to the translation library won't impact your code.

The translation system in Makerkit is versatile and can be used in:

1. Server components (RSC)
2. Client components
3. Server-side rendering

Utilizing Translations in your Next.js Supabase Project

The guide below will show you how to use translations in your Next.js Supabase project in all the scenarios mentioned above.

Initializing i18n in Server Components

When creating a new page, ensure to wrap it with the withI18n function. This function initializes the translations before rendering the server component.

Given that server components are rendered in parallel, it's uncertain which one will render first. Therefore, it's crucial to initialize the translations before rendering the server component on each page/layout.

import { withI18n } from '~/lib/i18n/with-i18n';
 
const Page = () => {
  return <div>My page</div>;
};
 
export default withI18n(Page);

Implementing Translations in Server Components

After initializing the translations, you can use the Trans component to translate strings in your server components.

import { Trans } from '@kit/ui';
 
const Page = () => {
  return (
    <div>
      <Trans i18nKey="auth:signIn" />
    </div>
  );
};
 
export default withI18n(Page);

Ensure to import the Trans component from @kit/ui and not directly from react-i18next.

Using the useTranslation Hook

The useTranslation hook is another way to translate strings in components that are not in the render path.

import { useTranslation } from 'react-i18next';
 
const MyComponent = () => {
  const { t } = useTranslation();
  
  return <div>{t('auth:signIn')}</div>;
};

Conclusion

By following these steps, you can easily add translations to your Next.js Supabase project. This approach ensures that your application is accessible to a global audience, providing a better user experience for all users.
