Npm's cldr-data

Npm module for Unicode CLDR JSON data.

Goal

• Allow i18n libraries to define CLDR data as versioned "peer" dependency.
• Provide tools to assist (in other words, ease the pain) on fetching the data.

Bonus goals

• Optimal for backend development. (Frontend, see Bower's cldr-data).
• Optimal for Node.js environment. (AMD, see Bower's cldr-data).

Usage

For libraries

On the package.json of your i18n library, define its CLDR data dependency by using the peerDependencies property.

"peerDependencies": {
  "cldr-data": ">=26"
}

On your library, access CLDR JSON data using require("cldr-data").

function Pluralize(locale) {
  var plurals = require("cldr-data/supplemental/plurals");
  var language = extractLanguageFrom(locale);

  // Your awesome pluralization logic
  pluralForm = doAwesomeStuffWith(
    plurals.supplemental["plurals-type-cardinal"][language]
  );

  return pluralForm;
}

For your convinience, use cldr-data in conjunction with cldr.js. You can find more details switching to the Foo Number Format Library Example or Application Example branches.

For applications

On the package.json of your applications, define its CLDR data dependency by using the dependencies or devDependencies property.

"dependencies": {
  "cldr-data": "26",
  "libraries-that-use-cldr-data": "x"
}

Locale coverage

By default, the locale coverage installed is core, which Unicode defines as the top tier languages and is equivalent to the json.zip content. There are two ways to modify the installation and get the full coverage instead.

Use the environment variable CLDR_COVERAGE

On the command line, set the locale coverage using the environment variable.

$ CLDR_COVERAGE=full npm install

Use the package.json cldr-data-coverage property

On the package.json of you application, set the locale coverage using the cldr-data-coverage property.

{
  ...
  "cldr-data-coverage": "full",
  ...
}
