Homework for the week is to install "node.js" and "mySql". Download and unzip week7
In the "week7/homework" folder you will find  5 files:

  1. default.htm, client -- test page to use the node.js server attached to mysql
  2. socket.js, client -- JavaScript object to send / receive packets from node.js server
  3. mysql.js, server -- a node.js JavaScript object to access mysql
  4. server.js, server -- a node.js JavaScript server to read command from clients, and return mysql data
  5. server.bat, a windows batch file to start the server.js server

in Mysql Workbench, you will need to make sure it has a "world" database, and add a user "clif" password "clif" or you can change the setting in the "mysql.js" file (at the bottom). You many need to grant user "clif" some privileges on the MAC.

You will need to install (at a command prompt) "mysql" and "websocket" node.js modules:

    c:/>npm install mysql
    c:/>npm install websocket

On Windows you can double-click on the file "server.bat" to start the node.js server

On a MAC you will need to start the server manually, at the command prompt, "cd .../week7/homework", then "node server.js"

On a MAC you may need to change the port 443 to 1200 (socket.js and server.js) (I changed this in the current download)

To start the application, double-click on the "default.htm" file

If anyone has trouble (inconceivable) let me know, and I can add some screen shots.
