#Screenshare

Screenshare is an application that allows a user to share their current session on a website. This currently works for Firefox, Chrome, Opera and Safari. For mobile devices, Chrome and Firefox are supported on Android.

DEMO video here of it in action

##Requirements

You must have NodeJS > 0.6.x installed, with socket.io and express modules. You can download the latest copy of NodeJS here.

npm install socket.io
npm install express

######Run the Example

1. Run app.js. node app.js

2. Navigate in your browser to http://localhost:3000 (Client Page) and http://localhost:3000/admin.html (Admin Page)

   This will bring up 2 pages. The first page will be the client page and the other will be the administration page.

3. On the client page mouse over the 'Help' tab

4. Enter in a key, then click the Create Key button.

5. On the admin page type in the key you just created and hit enter.

   Now you should be able to see exactly what is happening on the client screen. There are still plenty of bugs with this application but it is in a usable state for anyone to begin playing with.

######How To use

1. Make sure that your file structure follows lib/js & lib/css, then change the CDN and SocketCDN variables to your server environment.

2. Add the screenshare.js script public/lib/js/screenshare.js before the closing body tag </body> on your html file(s)

3. Run the app.js node app.js

4. Open your website (there should now be a help tab on the right of your page)

5. Enter in a key, then click the Create Key button.

6. Open up another browser page to http://localhost:3000/admin.html

7. On the admin page type the key you created on your site and hit enter

   Now you should be able to see exactly what is happening on the client screen. There are still plenty of bugs with this application but it is in a usable state for anyone to begin playing with.
