Use commander.js.

npm install commander

Then introduce commander.js into the code and use it directly.

Tips:

If it is just -p --port, without [type], the passed in is a Boolean value, true/false.

-p, -- port [type], pay attention to the space in the middle.

Go directly to the code

let express = require('express');let program = require('commander');  
let port = 3000     // 设置默认端口
let app = express() //启动一个web服务器
app.set('views','./views');       //设置视图的根目录
app.set('view engine', 'jade');   // 设置视图模板引擎
app.listen(port)
program  
.option('-p, --port [type]','Add port')  
.parse(process.argv);
if (program.port) port = program.port;
console.log('imovie start on port '+ port);
