Package Exports

@phensley/cldr

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@phensley/cldr) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

cldr-engine

Internationalization in Typescript with Unicode CLDR, batteries included

Install

Install the NPM package:

npm install --save @phensley/cldr

Using Yarn:

yarn add @phensley/cldr

Pacakge Naming

Packages with the cldr-* prefix represent pieces of the larger library and are designed to work together. The @phensley/cldr package pulls in the full functionality of the library.

Packages without the cldr-* prefix can be used in an application individually without pulling in the larger core library.

You can use any of the packages independent of the rest of the library:

Features

Implementation folows the CLDR specification supporting CLDR version 36.0.0
370 modern locales
Compact resource packs containing all scripts and regions for a given language
Language tag parsing, locale resolution, and distance-based enhanced language matching for improved locale fallback
Fast, compact, and extensible ICU message formatting
Both string and parts formatting for flexible markup styling
Date time, date interval, and relative time formatting
Full TZDB and CLDR timezone support covering the full range of TZDB untils, resolving deprecated timezone identifiers and aliases
Gregorian, ISO-8601, Japanese, Persian and Buddhist calendars.
Date formatting using flexible skeleton-based pattern matching
Date addition, date subtraction, date differencing and "field of visual difference" calculation
Cardinal and ordinal pluralization rules
Decimal numbers, currencies, units, and unit sequence formatting, with 157 different units
Arbitrary precision decimal math
Display names for languages, scripts, regions, currencies, units, calendar fields, etc
List formatting, measurement system, character order, and line order information
Optional Unit conversion package to convert quantities between CLDR units

Goals

Support a broad set of CLDR features in the browser "out of the box".
Support all scripts and regions for a language in a single compact resource pack.
Resolve the CLDR data size and dimensionality problems.
- In the case of English: ~40MB of JSON for 105 locales is compressed to a 194KB resource pack (44KB gzip), a factor of approx. 200:1 uncompressed, 1000:1 with gzip compression.
No additional library dependencies required.
No custom extraction of CLDR data or precompilation of formatters required.
Correctness and consistency across browsers and Javascript runtime environments.
Provide type-safety, reducing programming errors.
No familiarity with CLDR structure is required for developers to use this library.
High performance.
Arbitrary precision decimal math, to achieve the same accuracy in the browser as on the server.
