##Purpose

• This is a personal project/portfolio/repository for the author to show and prove his knowlegde in JavaScript, NodeJS, ExpressJs, Websocket, jQuery, & etc.

##Reasons

• For your information, the author does not have special interest in lottery. The reason of picking lottery as a personal project is that the author plan to implement dynamic routing by user's IP address in this project. For example, the main page will display Virginia Lottery Result if the user's IP address is in Virginia.
• Since Lottery Results are updating frequently, it is a good challenge to parse/scrape the official websites and display the latest results.

##Achievements & Proofs

1. It is possible to scrap or copy content from foreign/other website in Node.js
2. A schedule can be set to pull data from foreign/other website. (better than long polling)
3. There are a lot of better way to update the website instantly. (angular.js is not the only option, websocket is an option too)
4. Using jQuery on Node.js is possible. (through cheerio.js)
5. Create HTTPS server is easy and the SSL/TLS cert is free, all web servers should be running in a secure way.

##Installation ###In Linux SSH onto the machine and run the following commands:

apt-get install -y git screen

git clone https://github.com/jefftham/Lottery.git

screen -dmSL server_setup bash

screen -S server_setup -X stuff $'source Lottery/setup.sh\n'

The server will be running properly.

If you want to run node.js manually without restarting the SSH/terminal, copy & paste following code to terminal:

export NVM_DIR="/root/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"

##Use The setup.sh in the repository will start the server by default.

One may run node lottery_server.js if needed.
