Globalize
Globalize is a JavaScript internationalization library and Unicode CLDR localization engine. It provides a toolkit for formatting dates, numbers, and currencies using the Unicode Common Locale Data Repository and IANA time zones.
The project features a build-time localization compiler that precompiles rules into static formatters to reduce runtime overhead and bundle size. It includes a system for parsing and formatting complex strings using the ICU MessageFormat syntax, supporting variables, pluralization, and gender inflections.
The library covers a broad surface of localization capabilities, including bidirectional date and time parsing, number and currency tokenization, and relative time formatting. It manages locale data loading, application-wide language configuration, and message inheritance chains to resolve missing translation keys.
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.

How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
