SSR 服务器端渲染 服务器生成html字符串

cnpm i jade ejs

html                    <html>
head <head>
style <style></style>
link <link></link>
script <script></link>
</head> body
div
ul
li </html>

jade:

var html = jade.reander(标签名);

var html = jade.reanderFile("xxx.jade",{pretty:true,data....});

pretty:美化

属性 内容

div(id="div1",class="box") 内容

div#div1.box 内容

div&attributes({id:'div1', class:'box'}) 内容

div(class=["box1","box2","box3"])

样式:

div(sytle="width:200px;....")

div(sytle={width:"200px",....})

多行 | 或 . 或 include 文件名
数据:#{name}
循环:
        -for(){
li
-}
1.jade
html
head
style #div1{width:200px;height:200px;background:red;}
link(rel="stylesheet",href="index.css")
script(src="a.js")
script
|window.onload = function(){
| alert(1);
|}
body
div(style="width:200px;height:200px;background:red;") 内容
div(style={width:"200px",height:"200px",background:"red"}) 内容
div aaaa
|bbbb
|cccc
div(class="box1 box2 box3") class
div(class=["box1","box2","bo3"]) class arr
div&attributes({id:'div1', class:'box'})
ul
li 我叫#{name},今年#{age}岁
ul
-for(var i = 0; i < data.length; i++){
li 我叫#{data[i].name},今年#{data[i].age}岁
-}

1.js

var jade = require("jade");
var str = jade.renderFile("3.jade",{pretty:true,
name:"如花",age:18,
data:[
{name:"如花",age:18},
{name:"翠花",age:28},
{name:"豆腐花",age:38}
] }); console.log(str);//html页面

7、 jade 、 ejs、express集成模板


ejs:

cnpm i ejs

http://www.ejs.co/ 英文

https://ejs.bootcss.com/ 中文

<% '脚本' 标签,用于流程控制,无输出。

<%= 输出数据到模板(输出是转义 HTML 标签) 原样输出

<%- 输出非转义的数据到模板 转义成标签

<%-/= include 文件名%>

<%-/= include("文件名",数据)%>

<%-/= include %>直接将文件内容引过来


js:
var ejs = require("ejs");

ejs.renderFile("52.ejs",{
name:"翠花",age:20,
data:[
{name:"如花",age:18},
{name:"翠花",age:28},
{name:"豆腐花",age:38}
]
},function(err,str){
console.log(err,str);
});
52.ejs:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>无标题文档</title>
</head> <body>
<ul> <ul>
<%- include tmpli2.ejs%>
</ul> </ul>
</body>
</html>
tmpli2.ejs:
<%for(var i = 0; i < data.length; i++){%>
<li>我叫<%=data[i].name%>,今年<%=data[i].age%>岁</li>
<%}%>

7、 jade 、 ejs、express集成模板

express集成模板引擎

app.set("view engine","ejs/jade"); 设置模板引擎

app.set("views","./views"); 模板文件存放的目录

使用:

res.render("index",data);

consolidate

npm i consolidate

app.set("view engine",html); 设置模板引擎

app.set("views","./views"); 模板文件存放的目录

app.engine("html",consolidate.ejs/jade/pug/....); 使用什么方法去解析你的模板文件

consolidate.ejs--->ejs.renderFile

consolidate.jade--->jade.renderFile

app1.js(ejs)

var express = require("express");
var ejs = require("ejs");
var app = express(); app.listen(9000); app.get("/index.html",function(req,res){ ejs.renderFile("index.ejs",{name:"aaa",age:18},function(err,data){
res.send(data);
});
});

app2.js(ejs)

var express = require("express");
var app = express(); app.listen(9000); //配置模板引擎
app.set("view engine","ejs");
app.set("views","./views"); app.get("/index.html",function(req,res){
res.render("index.ejs",{name:"aaa",age:18});
});

app3.js(jade)

var express = require("express");
var app = express(); app.listen(9000); //配置模板引擎
app.set("view engine","jade");
app.set("views","./views"); app.get("/index.html",function(req,res){
res.render("index.jade",{name:"aaa",age:18});
});

app4.js(html)

var express = require("express");
var ejs = require("ejs");
var app = express(); app.listen(9000); //配置模板引擎
app.set("view engine","html");
app.set("views","./views");
app.engine("html",ejs.renderFile); app.get("/index.html",function(req,res){
res.render("index",{name:"aaa",age:18});
});

app5.js(html)

var express = require("express");
var consolidate = require("consolidate");
var app = express(); app.listen(9000); //配置模板引擎
app.set("view engine","html");
app.set("views","./views");
app.engine("html",consolidate.ejs); app.get("/index.html",function(req,res){
res.render("index",{name:"aaa",age:18});
});
