import i18next from 'i18next'
import { i18nextMiddleware, LanguageDetector } from '@os-utils/i18next-express-middleware'

// Initialize i18next
i18next
  .use(LanguageDetector) // Pass the LanguageDetector middleware
  .init({
    fallbackLng: 'en',

    // Pass the custom options if necessary
    detection: {
      // In what order will the detectors be started
      order: ['cookie', 'header'], // default: ['header']
      
      // Keys used by the detectors
      cookie: 'custom-cookie', // default: i18next
      header: 'custom-header', // default: Accept-Language
    },
  })


const app = express()
app.use(cookieParser())
app.use(i18nextMiddleware(i18next))
