I18n Date Patterns

This is a reference skill for building multilingual React apps with react-i18next and dayjs. It enforces patterns like useTranslation for all UI strings, useFormatting for currency and lists, and ICU MessageFormat for plurals. The anti-patterns section is the real value here: it explicitly forbids things like hardcoding strings, using .join() for lists, or new Date() for formatting. Comes with bundled references for the formatting hook API and Trans component examples. If you're working on a codebase that supports Hebrew or Arabic, the RTL guidance and logical properties approach will save you time. Low effort skill that acts as a guardrail.

i18n and Localization Patterns

Overview

This skill provides comprehensive guidance for implementing internationalization in React applications. It ensures ALL user-facing strings, date displays, currency, lists, and time calculations are locale-aware.

When to use this skill:

Adding ANY user-facing text to components
Formatting dates, times, currency, lists, or ordinals
Implementing complex pluralization
Embedding React components in translated text
Supporting RTL languages (Hebrew, Arabic)

Core Patterns

1. useTranslation Hook (All UI Strings)

Every visible string MUST use the translation function:

import { useTranslation } from 'react-i18next';
