//app.js
var express = require('express');
var app = express();
var homeRouter= require('./routes/home');
const i18next = require('i18next');
const i18nextMiddleware = require('i18next-express-middleware');
const Backend = require('i18next-node-fs-backend');
i18next
  .use(Backend)
  .use(i18nextMiddleware.LanguageDetector)
  .init({
    backend: {
      loadPath: __dirname + '/locales/{{lng}}.json',
      addPath: __dirname + '/locales/{{lng}}.missing.json'
    },
    detection: {
      order: ['querystring', 'cookie'],
      caches: ['cookie']
    },
    fallbackLng: 'en',
    preload: ['en', 'zh'],
    saveMissing: true
  });
  app.use(bodyParser.urlencoded({ extended: true }));
  app.use(bodyParser.json());
  app.use(i18nextMiddleware.handle(i18next));

//home.js
var express = require('express');
var router = express.Router();
router.get('/', function (req, res) {
  res.render("index.ejs") 
}

//index.ejs
<div>
 <h1><%=t("Welcome")%></h1>  //working fine in  template 
 <ul>
            <li class="nav-item dropdown" style="list-style-type: none;">

            </li>
