# Internationalization Helper
Helps manage internationalization (i18n) and localization (l10n) in multi-language applications.
## When to Use
- User requests i18n support
- Adding new languages
- Finding untranslated strings
- Managing translation files
- User mentions "translation", "i18n", "l10n", "locale"
## Instructions
### 1. Detect i18n Framework
**JavaScript/React:**
- react-i18next
- react-intl (FormatJS)
- i18next
- LinguiJS
**Vue:**
- vue-i18n
**Python:**
- gettext
- Django i18n
- Flask-Babel
**Ruby/Rails:**
- I18n gem (built-in)
Look for imports, config files, or translation directories.
### 2. Find Hardcoded Strings
Search for untranslated text:
```javascript
// Bad: Hardcoded
<button>Submit</button>
<p>Welcome, {user.name}!</p>
// Good: Translated
<button>{t('common.submit')}</button>
<p>{t('welcome.message', { name: user.name })}</p>
```
**Search patterns:**
- Strings in JSX/template tags
- Alert/error messages
- Form labels and placeholders
- Button text
- Validation messages
Exclude: code comments, console.log, test strings
### 3. Extract to Translation Files
**React-i18next format (JSON):**
```json
{
"common": {
"submit": "Submit",
"cancel": "Cancel"
},
"welcome": {
"message": "Welcome, {{name}}!"
}
}
```
**Gettext format (.po):**
```po
msgid "submit_button"
msgstr "Submit"
msgid "welcome_message"
msgstr "Welcome, %(name)s!"
```
### 4. Organize Translation Keys
**Best practices:**
- Namespace by feature: `users.profile.title`
- Group common strings: `common.buttons.save`
- Describe context, not content: `errors.login.invalid` not `errors.wrong_password`
- Consistent naming convention
### 5. Check Translation Coverage
Compare locale files to find missing translations:
```
en.json: 150 keys
es.json: 142 keys (missing 8)
fr.json: 150 keys ✓
Missing in es.json:
- users.profile.bio
- settings.privacy.title
[...]
```
### 6. Handle Pluralization
Different languages have different plural rules:
```javascript
// react-i18next
t('items', { count: 0 }) // "0 items"
t('items', { count: 1 }) // "1 item"
t('items', { count: 5 }) // "5 items"
// Translation file
{
"items_zero": "{{count}} items",
"items_one": "{{count}} item",
"items_other": "{{count}} items"
}
```
### 7. Date, Time, Number Formatting
Use locale-aware formatting:
```javascript
// Numbers
const price = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD'
}).format(29.99);
// Dates
const date = new Intl.DateTimeFormat('fr-FR').format(new Date());
```
### 8. RTL (Right-to-Left) Support
For Arabic, Hebrew:
- CSS: `direction: rtl;`
- HTML: `<html dir="rtl">`
- Logical properties: `margin-inline-start` instead of `margin-left`
### 9. Generate Translation Template
Create template for new locale:
```bash
# Copy keys from base language, empty values
cp locales/en.json locales/de.json
# Mark for translation
```
### 10. Best Practices
- Keep translations in separate files
- Use keys, not source text as keys
- Provide context to translators
- Test with long strings (German often longer)
- Use ICU MessageFormat for complex strings
- Avoid concatenating translated strings
- Extract all user-facing text
