Internationalization (i18n)

Guidelines for internationalization and translation management in OneKey.

Critical Restrictions

ABSOLUTELY FORBIDDEN (auto-generated files):

// ❌ NEVER modify these files - they are AUTO-GENERATED
// @onekeyhq/shared/src/locale/enum/translations.ts
// @onekeyhq/shared/src/locale/json/*.json

// ❌ NEVER hardcode text strings
<Text>Confirm</Text>

// ✅ CORRECT - Always use translation keys
import { ETranslations } from '@onekeyhq/shared/src/locale';
intl.formatMessage({ id: ETranslations.global__confirm })

Consequences of violation:

• Translation system corruption
• Loss of translation work
• Build failures in i18n pipeline
• Breaking localization for international users

Quick Reference

Using Translations in Components

import { useIntl } from 'react-intl';
import { ETranslations } from '@onekeyhq/shared/src/locale';

function MyComponent() {
  const intl = useIntl();

  return (
    <SizableText>
      {intl.formatMessage({ id: ETranslations.global__confirm })}
    </SizableText>
  );
}

Using formatMessage Outside Components

import { appLocale } from '@onekeyhq/shared/src/locale/appLocale';
import { ETranslations } from '@onekeyhq/shared/src/locale';

const message = appLocale.intl.formatMessage({
  id: ETranslations.global__cancel,
});

Translation Workflow

1. Design provides translation key like prime::restore_purchases
2. Run sync command: yarn fetch:locale
3. Convert key format: prime::restore_purchases → ETranslations.prime_restore_purchases
4. Use in code:

   {intl.formatMessage({ id: ETranslations.prime_restore_purchases })}
   

Translation Key Naming Pattern

namespace__action_description

Examples:
- global__confirm
- global__cancel
- swap__select_token
- wallet__create_wallet
- settings__dark_mode
