The React SDK enables you to use hooks to retrieve the user’s preferences.

​
Getting Started

​
1. Install the SDK

Install the SDK with your preferred package manager. 
npm install @microapp-io/react

​
2. Wrap Your App with the Provider

Wrap your application with the UserPreferencesProvider component. 
import { UserPreferencesProvider } from '@microapp-io/react';

function App() {
  return (
    <UserPreferencesProvider>
      <YourApp />
    </UserPreferencesProvider>
  );
}
For development, you can use the sandbox mode to test different language preferences: 
<UserPreferencesProvider sandbox={{ lang: 'pt' }}>
  <YourApp />
</UserPreferencesProvider>
The sandbox prop should only be used for local development. Do not use it in production.

​
3. Access Language Preferences

Use the useUserPreferences hook to access the user’s language preference. 
import { useUserPreferences } from '@microapp-io/react';

function LanguageDisplay() {
  const { lang } = useUserPreferences();
  
  return (
    <div>
      <p>Current language: {lang}</p>
    </div>
  );
}
The language preference is controlled by the user through the Microapp platform. Your application should respect this preference and adapt accordingly.

​
4. Create Translation Files

Store your translations in a separate file to keep them organized and maintainable. 
// translations.ts
export const translations = {
  'en': {
    greeting: 'Hello',
    welcome: 'Welcome to our app',
    description: 'This is a sample application'
  },
  'es': {
    greeting: 'Hola',
    welcome: 'Bienvenido a nuestra aplicación',
    description: 'Esta es una aplicación de muestra'
  },
  'pt': {
    greeting: 'Olá',
    welcome: 'Bem-vindo ao nosso aplicativo',
    description: 'Este é um aplicativo de exemplo'
  }
};

​
5. Render Localized Content

Use the language preference to display content in the appropriate language. 
import { useUserPreferences } from '@microapp-io/react';
import { translations } from './translations';

function LocalizedContent() {
  const { lang } = useUserPreferences();
  
  // Default to English if the user's language isn't supported
  const content = translations[lang] || translations.en;
  
  return (
    <div>
      <h1>{content.greeting}</h1>
      <h2>{content.welcome}</h2>
      <p>{content.description}</p>
    </div>
  );
}

​
6. Localize API Requests (Optional)

When fetching data from an API, you can include the user’s language preference in the request headers. 
import { useUserPreferences } from '@microapp-io/react';

function DataFetcher() {
  const { lang } = useUserPreferences();
  
  const fetchLocalizedData = async () => {
    try {
      const response = await fetch('https://api.example.com/content', {
        headers: {
          // Include the user's language preference in the request headers
          'Accept-Language': lang
        }
      });
      
      const data = await response.json();
      return data;
    } catch (error) {
      console.error('Error fetching localized data:', error);
    }
  };
  
  // ...
}
