The solution of sticky package problem of TCP for Node.Js !

// test.pack.js
'use strict';

// 初始化header内存
const headerBuf = Buffer.alloc(2);
// 初始化数据  <Buffer 61 62>
const dataBuf = Buffer.from('ab');
// 写入数据长度 <Buffer 00 02>
headerBuf.writeInt16BE(dataBuf.length, 0);

// <Buffer 00 02 61 62>
const buffer = Buffer.concat([headerBuf, dataBuf]);
const buffer2 = Buffer.concat([headerBuf, Buffer.from('cd')]);
