Globalize
Globalize est une bibliothèque JavaScript d'internationalisation et un moteur de localisation Unicode CLDR. Elle fournit une boîte à outils pour formater les dates, les nombres et les devises en utilisant le Unicode Common Locale Data Repository et les fuseaux horaires IANA.
Le projet dispose d'un compilateur de localisation au moment du build qui précompile les règles en formateurs statiques pour réduire la surcharge à l'exécution et la taille du bundle. Il inclut un système pour analyser et formater des chaînes complexes en utilisant la syntaxe ICU MessageFormat, prenant en charge les variables, la pluralisation et les flexions de genre.
La bibliothèque couvre une large surface de capacités de localisation, notamment l'analyse bidirectionnelle des dates et heures, la tokenisation des nombres et devises, et le formatage du temps relatif. Elle gère le chargement des données de localisation, la configuration de la langue à l'échelle de l'application et les chaînes d'héritage de messages pour résoudre les clés de traduction manquantes.
Features
- JavaScript Internationalization Libraries - Provides a comprehensive JavaScript toolkit for formatting dates, numbers, and currencies using Unicode CLDR and IANA data.
- Locale-Aware Date Parsing - Transforms localized date strings back into Date objects based on specified formats and locale rules.
- Regional Number Formatting - Converts numeric values into localized strings with support for percentages and compact notation.
- Time Zone Management - Imports IANA time zone information to enable accurate regional offsets during date and time processing.
- Static Generation - Generates static formatters and parsers during build time to reduce runtime overhead and eliminate data loading.
- IANA Time Zone Database Integrations - Integrates the IANA time zone database to calculate offsets and identifiers for localized date processing.
- CLDR Data Integration - Integrates official Unicode Common Locale Data Repository standards to drive regional formatting and parsing rules.
- Pluralization Rules - Resolves and formats messages based on locale-specific pluralization rules to ensure grammatical correctness.
- ICU Message Parsing - Implements logic for transforming ICU MessageFormat strings into structured trees for interpolation and pluralization.
- Locale Data Loading - Implements mechanisms for importing necessary Unicode CLDR and IANA time zone data during the application session.
- Formatter Precompilation - Precompiles localization rules into runtime modules to eliminate the need for shipping large locale data files.
- Internationalized Date Formatting - Provides locale-aware formatting and parsing to convert date objects into localized strings and vice versa.
- Localized Message Formatting - Translates message keys into user-readable strings using ICU patterns with support for variables, pluralization, and gender.
- Locale-Aware Currency Formatting - Transforms numeric values into localized currency strings based on specific currency codes and locale rules.
- Number Parsing - Transforms localized number strings, including percentages, back into numeric values based on locale-specific separators.
- Relative Date Formatting - Converts numerical values into localized strings representing relative time periods based on specific time units.
- Localization Configurations - Allows the definition of a global target language to ensure consistent formatting across all localization calls.
- Localized Unit Displays - Transforms numeric values into localized unit strings with options for short or narrow formatting.
- Locale Fallback Chains - Implements prioritized fallback chains to resolve missing translation keys by reverting to parent language bundles.
- Locale Inheritance Chains - Implements message inheritance chains to resolve missing translation keys by falling back to parent locales.
- Localization Instance Isolation - Enables the creation of isolated localization instances configured for specific languages and regions.
- Application Locale Management - Provides utilities for setting and retrieving the active language locale to match user regional preferences.
- Localization Pipeline Automation - Automates the loading of Unicode CLDR data and application messages via build tool integration.
- Build-Time Localization - Provides a compiler that replaces dynamic translation calls with static strings and optimized formatters at build time.
