因为某种原因，我们的项目必须采用smarty模板，一直没找到好用的npm包
不得已扒开了fis3-smarty, gulp-smarty的代码，找到了一个npm包
smarty4Js
然后解决了node环境渲染smarty的问题

代码如下：

// index.js: 
const express = require('express');
const smarty4Js = require('smarty4Js');
const path = require('path');
const app = express();
const smartyHelper = new smarty4Js();
const basePath = path.resolve('./');
smartyHelper.setBasedir(basePath);
const compiler = smartyHelper.compile('./index.tpl');
const html = compiler.render({
  title: 'node-parse-smarty',
  body: 'Smarty'
});
console.log(html);
app.get('/', (req, res) => {
  res.header('text/html');
  res.end(html);
});

app.listen(3000, () => {
  console.log('app is run at 3000 port');
});

// index.tpl: 
<!doctype html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport"
     content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <title>{%$title%}</title>
</head>
<body>
<div id="footer">{%$body%}</div>
</body>
</html>

结果如下：
