This time I will bring you the use of node swig rendering and what are the precautions for using node swig rendering. The following is a practical case, let's take a look.

First of all, of course, we use the express framework to build services on the node background.

var express = require('express');
var server = express();
server.listen(8080,'localhost',(req,res)=>{
   console.log('服务器启动...');
})

After the startup is successful, start setting up the relevant configuration of the swig template. The specific code is as follows:

npm install swig -s

Copy after login

Installation After success, add swig configuration, the code is as follows:

//配置摸板引擎
var swig = require('swig');
//参数1，摸板引擎的名称，固定字段
//参数2，摸板引擎的方法
server.engine('html',swig.renderFile);
//摸板引擎存放目录的关键字，固定字段
//实际存在的目录，html文件就在html文件夹下面
server.set('views',__dirname+'/html');
//注册摸板引擎，固定字段
server.set('view engine','html');
//关闭swig缓存,缓存的目的也是提高node服务器的响应速度
swig.setDefaults({cache:false});

Configure the data that needs to be rendered:

server.get('/',(req,res)=>{
  //render方法只有在使用摸板引擎之后才会生效，其中 参数1是需要渲染的摸板名称，参数2就是需要渲染到页面的一些参数
  res.render('temp',{
    name:'张三',
    user:{
      name:'栗子',
      age:18
    },
    lists:['item1','item2','item3','item4','item5',
    'item6','item7','item8','item9','item10','item11','item12',
    'item13','item14','item15','item16','item17','item18','item19',
    'item20','item21','item22','item23','item24','item25','item26']
  });
})

The specific code of the html file is as follows:




  
  
  
  Document


  摸板引擎
  
  姓名:{{name}}
  {% if user.name == '栗子' && user.age == '18'%}
  姓名:栗子
  {% elseif user.name == '张三'%}
  张三
  {% endif %}
  遍历数组
  {% for items in lists%}
  items
  {% endfor %}
  
   
  {% set arr = [1,2,3,4,5]%}
  {{arr.length}}
  
  {% include './common.html' %}

The specific page display As follows:

The above describes how to use the swig template engine to pass parameters to page rendering. Let’s take a look at how to use swig to extract the public parts of html:

Public parts of the html page, such as header, public js css files, navigation bar, etc.

Set a public page:


  node
  
  {% block css%}
  {% endblock %}
  



  首页
  关于我们
  商品列表
  登录
  注册

 
{% block content%}
{% endblock %}
 
{% block js%}
{% endblock %}

Copy after login

home.html


{% extends './layout.html'%}
{% block css %}

{% endblock %}
{% block content %}
 1
 2
 3
 4
 5
 6
{% endblock %}
{% block js %}

{% endblock %}

Copy after login

When starting the node server and rendering the home page, you will see

server.get('/',(req,res)=>{
  res.render('www/home',{});
})

Copy after login
