y18n

NPM version js-standard-style Conventional Commits

The bare-bones internationalization library used by yargs.

Inspired by i18n.

Examples

simple string translation:

const __ = require('y18n')().__; console.log(__('my awesome string %s', 'foo'));

output:

my awesome string foo

using tagged template literals

const __ = require('y18n')().__; const str = 'foo'; console.log(__`my awesome string ${str}`);

output:

my awesome string foo

pluralization support:

const __n = require('y18n')().__n; console.log(__n('one fish %s', '%d fishes %s', 2, 'foo'));

output:

2 fishes foo

Deno Example

As of v5 y18n supports Deno:

import y18n from "https://deno.land/x/y18n/deno.ts"; const __ = y18n({ locale: 'pirate', directory: './test/locales' }).__ console.info(__`Hi, ${'Ben'} ${'Coe'}!`)

You will need to run with --allow-read to load alternative locales.

JSON Language Files

The JSON language files should be stored in a ./locales folder. File names correspond to locales, e.g., en.json, pirate.json.

When strings are observed for the first time they will be added to the JSON file corresponding to the current locale.

Methods

require('y18n')(config)

Create an instance of y18n with the config provided, options include:

  • directory: the locale directory, default ./locales.
  • updateFiles: should newly observed strings be updated in file, default true.
  • locale: what locale should be used.
  • fallbackToLanguage: should fallback to a language-only file (e.g. en.json) be allowed if a file matching the locale does not exist (e.g. en_US.json), default true.

y18n.__(str, arg, arg, arg)

Print a localized string, %s will be replaced with args.

This function can also be used as a tag for a template literal. You can use it like this: __`hello ${'world'}`. This will be equivalent to __('hello %s', 'world').

y18n.__n(singularString, pluralString, count, arg, arg, arg)

Print a localized string with appropriate pluralization. If %d is provided in the string, the count will replace this placeholder.

y18n.setLocale(str)

Set the current locale being used.

y18n.getLocale()

What locale is currently being used?

y18n.updateLocale(obj)

Update the current locale with the key value pairs in obj.

Supported Node.js Versions
