port transfering

#in /etc/rc.local
iptables -A PREROUTING -t nat -i eth0 -p tcp -dport 80 -j REDIRECT --t 8000

Start app when booting

#`linux_config/chennode.sh` which should be put under `/etc/init.d/`

#make executable
chmod +x filename
#create
update-rc.d filename defaults
#delete
update-rc.d -f filename remove

Server Structure

index.js

create Server object and start server

server.js

hook project when needed and config basic server parameters

project_folder/

• proj_name.js

• controller.js

• views/

  dynamic web page needed. sqlauth, mongoauth

• models/

  database related. sqlauth, mongoauath

• public/

  static HTML file. ChenBlog, Socket.io

• config/(optional)

  database and middleware configuration. sqlauth, mongoauth

Module

• Express

• Q

• Socket.io

• Passport

• ejs/jade

• mongoose

• mysql

Experience

MongoDB

Setup

#Ubuntu
# add GPG key
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
# list file
echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
# install
sudo apt-get update
sudo apt-get install mongodb-org

#start service
sudo service mongod start

Socket.io

server:

sio.listen(3000) use different port for communication

• Send a function which will be executed in front-end: just get data not page

client:

<script src="http://localhost:3000/socket.io/socket.io.js"></script>
<script>
    var socket = io("http://localhost:3000");
</script>

• namespace: use URL path to specify channels

Application

• server:

• .broadcast.emit

• chat room

Reference

• youtube

Log

• 9/16/2015

  • complete socket.io real-time chatroom draft.

• 9/11/2015

  • completed sqlauth. Find mongoauth cannot be start with sqlauth, because of DOUBLE passport.initial() will forget session.

• 9/10/2015

  • figure out how to struct SQL related MVC by combining Promise theory and mysql module.

• 9/7/2015

  • change all project as middleware, make them more separated

  • add auth project with passport

• 7/7/2015

  • start when bootup BeagleBone

  • merge BeagleBone branch to master

• 7/3/2015

  • add support for Hexo blog

  • deeper understand express.static()

• 6/23/2015

  • socket.io:

  • this: refer

    Specify at the call time func.call & func.apply same: specify object
    diff: how to tranfer additional arg

• 6/22/2015

  • Markdown Tool

• 6/21/2015

  • Each module is like a class, add .config function to perform constructor function.

• 6/19/2015

  • plain design: define function separately, require & chain them together at the index file

    separation rule is decided with characteristic of projects

• 6/18/2015

  • a module can return a function or object

• 6/16/2015

• 6/15/2015
