SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers build applications that can be easily adapted for different languages and regional formats, ensuring a seamless user experience for a global audience.

Core Features & Use Cases

  • Internationalization (i18n): Engineering applications to support multiple languages and regions from the ground up.
  • Localization (l10n): Adapting the application for specific locales, including translation, number, date, and currency formatting.
  • Use Case: You are developing a web application and need to support users in English, Spanish, and French. This Skill provides the guidelines and techniques to externalize strings, handle pluralization, format dates and numbers correctly for each locale, and manage Right-to-Left (RTL) text direction.

FAQPage Schema
How do I set up internationalization and localization for a React application?

To set up internationalization for a React application, you externalize text strings using message formats like ICU, handle pluralization, and format dates, numbers, and currencies via JavaScript's Intl API. This Skill provides implementation patterns and guidelines for structuring these workflows.

What is the best way to handle Right-to-Left (RTL) text direction in a localized web app?

To handle Right-to-Left (RTL) text direction in a localized web app, you should use CSS logical properties. This Skill provides guidelines for implementing RTL support alongside your internationalization and text externalization workflows.

How does the JavaScript Intl API work for locale-specific date and currency formatting?

The JavaScript Intl API works for locale-specific formatting by providing native functions to format dates, times, numbers, and currencies according to regional settings. This Skill explains how to integrate the Intl API into your internationalization workflow.

Can I use ICU message format for text externalization and pluralization in Node.js?

Yes, you can use ICU message format for text externalization and pluralization in Node.js. This Skill covers implementation patterns for both React and Node.js, guiding you on how to externalize strings and manage complex pluralization rules.

What testing strategies should I use for internationalization before actual translation?

Pseudo-localization is a recommended testing strategy for internationalization before actual translation. This Skill covers workflows for translation management and testing strategies like pseudo-localization to ensure your application handles different text lengths and characters correctly.

When do I need to externalize strings for software localization?

You need to externalize strings for software localization when building an application intended for a global audience. This Skill helps you engineer applications from the ground up to support multiple languages by separating translatable text from your code using message formats.
