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：
