Using this library will listen to tcp ports externally

[SecGPT]

var request = require('sync-request');
var res = request('GET', 'http://www.baidu.com');
console.log(res.getBody().toString());

setTimeout(() => {
    console.log('sleep');
}, 10000000);

run node app.js

It seems that sync-rpc will listen
