I18n Localization

This handles the grunt work of internationalizing your app: detecting hardcoded strings, managing translation files, and making sure you don't ship broken RTL layouts. It covers common patterns for React (react-i18next), Next.js (next-intl), and Python (gettext), plus includes a checker script to catch strings you forgot to translate. The guidance on CSS logical properties for RTL is genuinely useful if you're shipping to Arabic or Hebrew markets. Honestly, most teams skip proper i18n until it's painful to retrofit, so having templates for locale file structure and ICU message format saves you from that mess. The checklist is basic but hits the things people actually forget, like date formatting and fallback languages.

i18n & Localization

Internationalization (i18n) and Localization (L10n) best practices.


1. Core Concepts

TermMeaning
i18nInternationalization - making app translatable
L10nLocalization - actual translations
LocaleLanguage + Region (en-US, tr-TR)
RTLRight-to-left languages (Arabic, Hebrew)

2. When to Use i18n

Project Typei18n Needed?
Public web app✅ Yes
SaaS product✅ Yes
Internal tool⚠️ Maybe
Single-region app⚠️ Consider future
Personal project❌ Optional

3. Implementation Patterns

React (react-i18next)

import { useTranslation } from 'react-i18next';

function Welcome() {
  const { t } = useTranslation();
  return <h1>{t('welcome.title')}</h1>;
}

Next.js (next-intl)

import { useTranslations } from 'next-intl';

export default function Page() {
  const t = useTranslations('Home');
  return <h1>{t('title')}</h1>;
}

Python (gettext)

from gettext import gettext as _

print(_("Welcome to our app"))
