Internationalization (i18n) and Localization (L10n) best practices.
| Term | Meaning |
|---|---|
| i18n | Internationalization - making app translatable |
| L10n | Localization - actual translations |
| Locale | Language + Region (en-US, tr-TR) |
| RTL | Right-to-left languages (Arabic, Hebrew) |
| Project Type | i18n Needed? |
|---|---|
| Public web app | ✅ Yes |
| SaaS product | ✅ Yes |
| Internal tool | ⚠️ Maybe |
| Single-region app | ⚠️ Consider future |
| Personal project | ❌ Optional |
import { useTranslation } from 'react-i18next';
function Welcome() {
const { t } = useTranslation();
return <h1>{t('welcome.title')}</h1>;
}
import { useTranslations } from 'next-intl';
export default function Page() {
const t = useTranslations('Home');
return <h1>{t('title')}</h1>;
}
from gettext import gettext as _
print(_("Welcome to our app"))

| Issue | Solution |
|---|---|
| Missing translation | Fallback to default language |
| Hardcoded strings | Use linter/checker script |
| Date format | Use Intl.DateTimeFormat |
| Number format | Use Intl.NumberFormat |
| Pluralization | Use ICU message format |
