Vue-Router 2: Uncaught RangeError: Maximum call stack size exceeded
I was quickly establishing the basic structure of my new project at that time, and so there were many details I ignored. When I found the above error information, I was shocked. WTF is it? After some attempts, I found the problem is that there were some Vuejs component named "RouterView" which has <router-view></router-view> inside them, and that was the cause. After I renamed their router component to names other than "RouterView", the above error information disappeared.

Deploy Nodejs Project on CentOS
The server is php-and-mysql-available with the help of Webmin (a web-based unix system management tool). So there is no need for me to install mysql myself. What's more, I have already a nodejs program available to run in my laptop (window OS) and the Baidu BAE (unix OS). Due to preassembled php program, the 80 port is employed and the root path for front-end files under 80 port is located in /home/username/public_html. To avoid confusion between php projects and nodejs projects, I created a new folder named "node-server" under /home/orzzone/ path. In a conclusion, I uploaded my Nodejs project files to the path '/home/username/node-server'.

Common Linux Commands
chmod 754 myfile: This is equivalent to the command above. Here the digits 7, 5, and 4 each individually represent the permissions for the user, group, and others, in that order. Each digit is a combination of the numbers 4, 2, 1, and 0. 4 stands for "read", 2 stands for "write", 1 stands for "execute", and 0 stands for "no permission". So 7 is the combination of permissions 4+2+1 (read, write, and execute), 5 is 4+0+1 (read, no write, and execute), and 4 is 4+0+0 (read, no write, and no execute).

phpMyAdmin导出数据表失败
如果按以前的习惯,我一般是在自己本地上起一个MySQL服务,将网站上的数据通过phpMyAdmin导出一份副本到本地再通过本地phpMyAdmin导入本地MySQL服务中供本地开发时使用。今天决定借鉴公司后端程序员们的做法,另行创建一个公网可以访问到的数据库作为测试数据库,本地开发时直接连接这个测试数据库,生产环境上则改为正式数据库。

Stack built with Javascript
栈是一种遵从后进先出(LIFO,last-in-first-out)原则的有序集合。新添加的活待删除的元素都保存在栈的末尾,称作栈顶,另一端就叫栈底。在栈里,新元素都靠近栈顶,旧元素都接近栈底。

Install Node.js
After you install Node.js by using an installer from the Node.js website. You'll see some executable files and the node_modules folder: node.exe: This file starts a Node.js JavaScript engine. If you pass in a JavaScript file location, Node.js executes that script. If no target avaScript file is specified, a script prompt allows you to execute JavaScript code directly from the console. npm.cmd: You use this command to manage the Node.js packages. node_modules: This folder contains the installed Node.js packages. These packages act as libraries that extend the capabilities of Node.js.
