如何在普通JS文件中获取i18next.t（）？

Question

概述

需要国际化的实际应用程序，使用i18next实现。

问题

在项目结构中，有constants.js（普通JS），我正在尝试获取i18next.t()进行翻译。请找到相关代码。

index.js

import React,{Suspense} from "react";
import ReactDOM from "react-dom";
import "./style/index.scss";
import App from "./app";
import createSagaMiddleware from "redux-saga";
import { createStore, applyMiddleware } from "redux";
import { Provider } from "react-redux";
import rootReducer from "./reducers";
import rootSaga from "./sagas";
import './i18n';

const sagaMiddleware = createSagaMiddleware();
const store = createStore(rootReducer, applyMiddleware(sagaMiddleware));
sagaMiddleware.run(rootSaga);

ReactDOM.render(<Provider store={store}>

    <App store={store} />

</Provider>,
    document.getElementById("root")
);

App.js

import React from "react";
import "./App.scss";
import MyOrders from "../component/my-orders";
import { toast } from "react-toastify";
import "react-toastify/dist/ReactToastify.css";
import i18n from 'i18next'

toast.configure({ autoClose: 5000 });

const changeLanguage = (lng) => {
    i18n.changeLanguage(lng);
};


const App = () => {


    return (
        <div className="App">
            <div align="left">
                <button className="btn btn-group-sm" onClick={() => changeLanguage('de')}>German</button>
                <button className="btn btn-group-sm" onClick={() => changeLanguage('en')}>English</button>
            </div>
            <MyOrders />
        </div>
    );
};

export default App;

i18n.js

import i18n from "i18next";
import detector from "i18next-browser-languagedetector";
import { reactI18nextModule } from "react-i18next";

import translationEN from '../public/locales/en/translation.json';
import translationDE from '../public/locales/de/translation.json';

// the translations
const resources = {
  en: {
    translation: translationEN
  },
  de: {
    translation: translationDE
  }
};

i18n
  .use(detector)
  .use(reactI18nextModule) // passes i18n down to react-i18next
  .init({
    resources,
    lng: "en",
    fallbackLng: "en", // use en if detected lng is not available

    interpolation: {
      escapeValue: false // react already safes from xss
    }
  });

export default i18n;

constants.js（纯JavaScript文件，导出多个常量对象）

//here I want to translate content

我没有运气就尝试了以下解决方案：Solution

您可以从i18n文件导入i18n.js实例，该实例上包含t。

import i18n from '../i18n';

i18n.t // <- use it.
