```
## Usage
```JS

// EasyTemplateJS-express
const view = require('easytemplatejs-express');
// EasyTemplateJS-Express view render middleware
view(app, {
cache: true, // Whether to open the cache; default is true
//cache: process.env.NODE_ENV == 'production',
enableScript:true, // enable <etj-script>; default is true
enableStyle:true, // enable <etj-style>; default is true
views: './views' // template file directory
});
```
## Demo
- **app.js**
```JS
const express = require('express')
const app = express()
// EasyTemplateJS-express
const view = require('easytemplatejs-express');
// EasyTemplateJS-Express view render middleware
view(app, {
views: './views' // template file directory
});
app.get('/users', function (req, res) {
res.render('user', {
name: 'Jay',

}
}%
</ul>

## EasyTemplateJS Core Object
如果需要获得 EasyTemplateJS 的核心对象进行调用，可通过中间件函数的 `.templateEngine` 属性获得。
If you need to get the core object of EasyTemplateJS to make a call, you can get it use the `.templateEngine` property of the middleware function.
```JS
const view = require('easytemplatejs-express');
// Get EasyTemplate core Object
var Et=view.templateEngine;
// Use Et
Et.tmplSettings={
// 脚本表达式开始结束标记%{ JS script }%
scriptBegin:"%{",
scriptEnd:"}%",
// 输出表达式开始结束标记 {name}
outBegin:"{=",
outEnd:"}",
// 转义输出表达式开始结束标记 {-name}
escapeOutBegin:"{-",
escapeOutEnd:"}"
}
```
## 内嵌 Script 和 CSS 支持/Embedded JavaScript and CSS
```javascript
view(app, {
enableScript:true, // enable <etj-script>; default is true
enableStyle:true, // enable <etj-style>; default is true
...
});
```

- **CSS 代码支持**
将 CSS 代码放在 `<etj-style>` ... `</etj-style>` 标签之间。
