本篇文章给大家介绍一下浏览器中使用模板引擎的方法、Node中使用模板引擎的方法，以及通过案例聊聊使用模板引擎渲染HTML的方法。
【推荐学习：《nodejs 教程》】
文件结构
实现代码
const fs = require('fs');
fs.readdir('G:/pink_code/Node_Study/02',(err,list) => {
if (!err) {
console.log(list);
}
})代码输出
[ '01_http-helloWorld.js', '02_使用readdir获取指定路径下的所有文件名.js', 'www' ]
1. 安装art-template
npm install art-template
2. 通过script标签引入art-template
<script src="./node_modules/art-template/lib/template-web.js"></script>
3. 使用模板引擎语法进行调用
<script src="./node_modules/art-template/lib/template-web.js"></script>
<script>
const test = template('tpl',{
name: 'China'
});
console.log(test);
</script>1. 安装art-template
npm install art-template
2. 在需要使用模板引擎的模块中加载art-template
3. 查文档，使用模板引擎的API
在Node中使用模板引擎的一个小案例
const template = require('art-template');
const test = template.render('hello {{name}}',{
name: 'NodeJs'
})
console.log(test);输出结果
hello NodeJs
