React Multilingual with redux

A simple and slim (Only 6KB) multi-lingual component for React with Redux without react-intl or react-i18n

Install

npm i react-redux-multilingual --save

Wiring it up

import translations from './translations'
import { IntlReducer as Intl, IntlProvider } from 'react-redux-multilingual'
import { createStore, combineReducers } from 'redux'
import { Provider } from 'react-redux'
import App from './App'

let reducers = combineReducers(Object.assign({}, { Intl }))
let store = createStore(reducers)

ReactDOM.render(
  <Provider store={store}>
    <IntlProvider translations={translations} locale='en'>
      <App />
    </IntlProvider>
  </Provider>
, document.getElementById('root'))

Translations format

The translations props accepts object in this format

{
  en: {
    locale: 'en-US',
    messages: {
      hello: 'how are you {name}'
    }
  },
  zh: {
    locale: 'zh',
    messages: {
      hello: '你好！你好吗 {name}'
    }
  }
}

Translate using hook

import { useTranslate } from 'react-redux-multilingual'

function App () {
  const t = useTranslate()

  return (
    <div>
      {t('hello', { name: 'Foo Bar'})}
    </div>
  )
}

Translate using higher-order component (HOC)

import { withTranslate } from 'react-redux-multilingual'

const App = ({ translate }) = {
  return (
    <div>
      {translate('hello', { name: 'John Doe' })}
    </div>
  )
}

module.exports = withTranslate(App)

Translate using Context

const App = (props, context) => {
  return (
    <div>
      {context.translate('hello', { name: 'John Doe' })}
    </div>
  )
}

App.contextTypes = {
  translate: React.propTypes.func
}

module.exports = App

Setting the initial locale

Option 1: Pass your locale to initial state of your reducer

let store = createStore(reducers, { Intl: { locale: 'zh'}})

Option 2: Dispatch an action to change locale

import { IntlActions } from 'react-redux-multilingual'
let store = createStore(reducers)
store.dispatch(IntlActions.setLocale('zh'))
