   import enLocale from './languages/en-US'
   import zhLocale from './languages/zh-US'
   
   // locales already build in
   intl.init({
     locales:{
       'en-US':enLocale
       'zh-CN':zhLocale
     },
     currentLocales:'en-US'

Features

• Not only key=>string but key=>object

      const enUS= {
          hi:'Hi',
          buttons:{
              submit:'Submit',
              cancel:'Cancel'
          }
      }
  

• Multiple way to get value

  
  intl.get('hi')
  
  intl.get('buttons.submit')
  
  intl.select( s =>{
      return {
          user:s.user,
          submitBtn:s.buttons.submit
      }
  })
  

• Template support

  // assume you had locale data like this
  const enUS = {
      greet:'Hi,{userName}!'
      formTip:{
           input:'Please input {label}',
           min:"Can't smaller than {min}"
      }
  }
  
  //useCase.js
  intl.getReplaced('greet',{userName:'Neo'})// 'Hi,Neo!'
  
  const formTip = intl.get('formTip')
  intl.replace(formTip.input,{label:'First Name'}) // 'Please input First Name'

Typesafe Usege

1. declare language

   //en-US.ts
   const enLocale = {
       hi: 'Hi',
       table:{
           createdAt: 'Created At'
       }
       user:{
         name: 'Name'
       }
   }
   export type EnLocal = typeof enLocale
   export default enLocale

2. declare typesafe select function

   //pickLocale.ts
   import intl from 'intl-lightly'
   import { EnLocal } from '../locales/en-gb'
   
   /**
   * Pick some locale with intellisense
   */
   export function pickLocale<T extends (local: EnLocal) => any>(pick: T) {
       return intl.select<EnLocal, ReturnType<T>>(pick)
   }

3. Use pickLocale in component

   export function Profile(){
       const locale = pickLocale(s=>s.user)
       return (<div>
           <div>{locale.name}</div>
       </div>)
   }
