koa2入门--09.art-template高速模板引擎的使用

首先在项目文件夹下使用 cmd,输入:npm install --save art-template koa-template

art-template语法参考:http://aui.github.io/art-template/zh-cn/docs/syntax.html,同时也支持ejs模板语法

后端:

//koa-art-template模板引擎
const koa = require('koa');
var router = require('koa-router')();
var render = require('koa-art-template');
const static = require('koa-static');
const bodyParser = require('koa-bodyparser');
const session = require('koa-session');

var app = new koa();
app.use(static('./www'));
app.use(bodyParser());
var keys = [];
(()=>{
    for(var i=0;i<1000;i++){
        keys.push(Math.random()+100);
    };
});
app.keys = keys;
app.use(session({
    maxAge:1000,
    keys:'koa:sess'
},app));

/*
    render(app,{
        root:'模板路径',
        extname:'.art', //模板文件尾
        debug:  process.env.NODE_ENE !== 'production' //打印报错
    });
*/
render(app,{
    root:'views',
    extname:'.art',
    debug: process.env.NODE_ENV !== 'production'
});

router.get('/',async (ctx)=>{
    await ctx.render('index');
});
app.use(router.routes());
app.use(router.allowedMethods());
app.listen(80);

文件目录结构:

 

 

前端:

<!DOCTYPE html>
<!--[if lt IE 7]>      <html class="no-js lt-ie9 lt-ie8 lt-ie7"> <![endif]-->
<!--[if IE 7]>         <html class="no-js lt-ie9 lt-ie8"> <![endif]-->
<!--[if IE 8]>         <html class="no-js lt-ie9"> <![endif]-->
<!--[if gt IE 8]><!--> <html class="no-js"> <!--<![endif]-->
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <title></title>
        <meta name="description" content="">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <link rel="stylesheet" href="">
    </head>
    <body>
        <!--[if lt IE 7]>
            <p class="browsehappy">You are using an <strong>outdated</strong> browser. Please <a href="#">upgrade your browser</a> to improve your experience.</p>
        <![endif]-->
        <div style="width: 200px;height: 200px;background: black;"></div>
        {{ '123' }}
        <script src="" async defer></script>
    </body>
</html>

效果:
