from simple service node

1. build a app.js file

const http = require('http');
const chalk = require('chalk');
const conf = require('./config/defaultConfig')

const server = http.createServer((req,res)=>{
    res.statusCode = 200;
    res.setHeader('Content-Type','text-plain');
    res.end("hello http!")
})

server.listen(conf.port,conf.hostsname,()=>{   //conf.port:3000(端口号，随便写)    conf.hostname:127.0.0.1
    const addr = `http://${conf.hostname}:${conf.port}`;
    console.info(`Server started at ${chalk.green(addr)}`)
})

　　

2. At this terminal node app.js, you can start the service. But not hot update each modification, we can supervise the installation of a global

3. At this time no need to use node app.js started, you can use Supervisor app.js start

npm i -g supervise
