The document outlines the development of a web-based Hangman game using modern technologies like Meteor and Node.js, emphasizing real-time updates and cross-platform compatibility. It covers the requirements, research, implementation, and deployment processes, alongside practical examples and code snippets. Additionally, it promotes community engagement through coding events and invites collaboration in its development.

11. Implementation
• Installation and Test
• Prepare Client
• Prepare Models
• Prepare Server
• Secure
• Deploy
Incoming Code
Focus on explanation,
and review code later.

12. hangmanapp.meteor.com

13. • Mac / Linux Only (Windows coming soon™)
> curl https://install.meteor.com | /bin/sh
• Create project
> meteor create hangman && cd hangman
• Test
> meteor
Installation

14. Prepare Client (client.js, hangman.html)
Objective: Define client sections/content that is
dynamic and programmable.
• Create your layout
• Convert to template sections
• Define the Templates for each section

15. Prepare Client (client.js, hangman.html)
Example: How to define sections, templates, and the display logic.

16. Prepare Client (model.js)
Objective: Define the data you’d like to keep.
• Optionally, define code that is shared between
the client and the server.

17. Prepare Models (model.js)
Example: Complete contents of the model.js file.

18. Prepare Server (server.js)
Objective: Define the how the client should
interact with the server, and any business logic.
• Define processing and publishing of data
• Referee and arbitrate the game

19. Prepare Server (server.js)
Example: Methods available to the client.

20. Prepare Server (client.js, server.js)
Example: How does the guess method get called?

21. Secure the Application
By default the application is insecure and all
clients receive a copy of all the data.
Why? Because it’s easier to develop the app.
To secure you remove the autopublish and
insecure packages. Then, define what is
allowed and published.

22. Prepare Server (server.js, client.js)
Example: Securing the application.

23. Deploy the Application
As simple as running a single command
> meteor deploy hangmanapp.meteor.com
Once deployed all clients will receive the
latest code.
