Adding a New Language

1. Frontend Locale Files

Create:

• frontend/src/locales/<lang>/common.json
• frontend/src/locales/<lang>/auth.json
• frontend/src/locales/<lang>/calendar.json
• frontend/src/locales/<lang>/booking.json
• frontend/src/locales/<lang>/settings.json
• frontend/src/locales/<lang>/admin.json
• frontend/src/locales/<lang>/automation.json
• frontend/src/locales/<lang>/errors.json
• frontend/src/locales/<lang>/validation.json
• frontend/src/locales/<lang>/emails.json
• frontend/src/locales/<lang>/notifications.json
• frontend/src/locales/<lang>/mobile.json

Then update frontend/src/i18n/types.ts:

• add the language code to SUPPORTED_LANGUAGES

2. Backend Locale Files

Create:

• backend-nestjs/src/i18n/<lang>/auth.json
• backend-nestjs/src/i18n/<lang>/validation.json
• backend-nestjs/src/i18n/<lang>/calendar.json
• backend-nestjs/src/i18n/<lang>/booking.json
• backend-nestjs/src/i18n/<lang>/email.json
• backend-nestjs/src/i18n/<lang>/notifications.json
• backend-nestjs/src/i18n/<lang>/errors.json
• backend-nestjs/src/i18n/<lang>/success.json

3. Database Validation

Extend language enum validation (DTOs/middleware) to include the new language.

4. Android Native Strings

Create:

• frontend/android/app/src/main/res/values-<lang>/strings.xml

5. Run Validation

npm run i18n:validate
npm run i18n:export
