Repository of localized pluralization functions. Usable in Node.js or in the browser.


Install via npm:

% npm install pluralizers


The default locale is en (English). Thus, a require('pluralizers') implicitly does require('pluralizers/en').

var sprintf   = require('sprintf').sprintf;
var pluralize = require('pluralizers');
var entry = { zero: 'no items', one: 'one item', other: '%(count)s items' };
pluralize(entry, 0)   // => 'no items'
pluralize(entry, 1)   // => 'one item'
pluralize(entry, 2)   // => '%(count)s items'
sprintf(pluralize(entry, 42), { count: 42 })   // => '42 items'

You can fetch a different localization by requiring a specific locale:

var pluralize = require('pluralizers/de');

English (en), Dutch (nl), German (de), Brazilian Portuguese (pt-br), Russian (ru) and Spanish (es) are currently the only supported locales. Pull requests welcome.


Here's a quick guide:

  1. Fork the repo and make install.

  2. Run the tests. We only take pull requests with passing tests, and it's great to know that you have a clean slate: make test.

  3. Add a test for your change. Only refactoring and documentation changes require no new tests. If you are adding functionality or are fixing a bug, we need a test!

  4. Make the test pass.

  5. Push to your fork and submit a pull request.
