use-i18n

Simple react hooks for international project. No other dependencies.

最简单的用 react hooks 实现国际化的 hooks。无任何其他依赖。

How to use? 怎样使用?

  1. Install the package:

安装:

yarn add use-i18n
//or npm i -S use-i18n
//or cnpm i -S use-i18n
  1. Provider to your application:

在应用上层加 Provider:

import React from 'react';
import ReactDOM from 'react-dom';
import { TransProvider } from 'use-i18n';
import App from './app';
import i18n from './i18n';

ReactDOM.render(
  <TransProvider i18n={i18n}>
    <App />
  </TransProvider>,
  document.getElementById('root'),
);
  1. Create i18n.js file:

创建 i18n.js 文件:

const i18n = {
  en: {
    welcome: 'hello',
  },
  'zh-CN': {
    welcome: '你好',
  },
};

export default i18n;
  1. Use I18n in your components:

在组件中使用:

import React from 'react';
import { useI18n } from 'use-i18n';

const App = () => {
  const t = useI18n();

  return <div>{t.welcome}</div>;
};

export default App;
  1. Change language:

改变语言:

import React from 'react';
import { useI18n, setLang } from 'use-i18n';

const App = () => {
  const t = useI18n();
  const [lang, setNewLang] = setLang();
  const change = () => {
    setNewLang('en');
  };
  return (
    <div>
      <div>{t.welcome}</div>
      <div>{lang}</div>
      <div onClick={change}>change</div>
    </div>
  );
};

export default App;
  1. Done, you can check localstorage。

完成了,打开 localstorage 查看如何运作

How it works? 原理:

  • Detects your browser lang

  • Try to find locales in locales storages

  • If locales are not in locales storages or lang store in local storage is different that the browser lang

    • Load accurate locales, if it doesn't find one matching the browser lang, fallback to zh-CN
    • Set downloaded locales and lang in localStorage
  • Add locales in context

  • 检查浏览器语言

  • 检查 localstorage 里有没有缓存

  • 如果没有缓存则把语言文件缓存到 localstorage

    • 如果没有检测到浏览器语言,则默认为简体中文
    • 在 localstorage 中设置语言和语言文件
  • 添加本地化到 context 中
