Simple Languages

A small wrapper for switching languages. Inspired by react-localization and rewritten using Proxy for a much smaller code base (50 ~ 80 lines of codes).

Installation

npm install --save simple-languages or yarn add simple-languages

Usage

Basic usage

import createLanguages from 'simple-languages'

// create the Languages object
const Languages = createLanguages()

// set the language, it is 'en' by default
Languages.lang = 'vi'

/* set the language data, it can be overwrite anytime
 * please note that the words "formatString", "lang" and "data" are reserved
 */
Languages.data = {
  en: {
    hello: 'Hello'
  },
  vi: {
    hello: 'Xin chào'
  }
}

console.log(Languages.hello) // => Xin chào

Languages.lang = 'en' // change language by setting the lang property

console.log(Languages.hello) // => Hello

Format string with placeholder

Basic usage

import createLanguages from 'simple-languages'
import formatString from 'simple-languages/formatString'

const Languages = createLanguages()
Languages.data.en = {
  hello: 'Hello, {0} and {1}!!!'
}

// ...do the same as above then
Languages.formatString = formatString

console.log(Languages.formatString(Languages.hello, 'John', 'David')) // => Hello, John and David!!!

With react

import formatString from 'simple-languages/formatString-react'

Caveats

Since this plugin using Proxy which is only supported by modern browsers. https://caniuse.com/#search=proxy.

However, a polyfill can be used to support IE9+.
