SSR 服务器端渲染 服务器生成html字符串

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
ejs:
cnpm i ejs
<% '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>

tmpli2.ejs:
<%for(var i = 0; i < data.length; i++){%>
<li>我叫<%=data[i].name%>，今年<%=data[i].age%>岁</li>
<%}%>

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});
