Bring an interactive Tic-Tac-Toe game to life! You'll start with a plain JavaScript program that can be played in the terminal. From there you'll extend the game logic into a full Backbone web application and connect it to a back-end API (which will be provided).
With this project you'll get exposure to the following skills:
- JavaScript unit testing with Jasmine
- Program/code design from scratch
- Writing an application with complex model logic
- Reworking existing code for a new environment (plain JS -> Backbone)
- Backbone API integration
This project uses the same Backbone scaffold from the previous Backbone projects. For the first wave you will not need to use Backbone or jQuery at all, however it will be simpler to convert your code to Backbone later on with all of the scaffold in place.
Because the initial implementation of a Tic-Tac-Toe game involves more coding and testing than the later coversion to Backbone you will be working in pairs to complete portion of the project (wave one). One person in the pair should fork the main Ada repository and give collaborator access to their partner.
However for the later waves everyone will be working individually. To make this work, once we switch to wave two and beyond the partner who did not fork from Ada should create their own fork from their partner's fork. This process works the same way as forking from Ada -- you open your pair partner's GitHub repo website and click the Fork button.
For the individual waves each person should still submit their Pull Requests to the original Ada repository.
Because this uses the scaffold you still need to run npm install after forking and cloning the repository. You do not need to run npm start until waves two and three, because until then your project code will not be a web application.
To run your tests you should use the command npm test.
If you want to interact with your game in the terminal via a REPL, you'll need to do things in a specific way (due to the scaffold's use of webpack).
To access the REPL you should use the command npm run repl in your project directory. Once in the REPL, you'll need to use the following syntax to import your file (this example assumes it was named src/game.js):
var Game = require('game').default;
var game = new Game();NOTE: This only works if your game.js file has an export default line in it, which it should (it'll be necessary for the Backbone conversion).
This project is divided into three waves that will be completed over the next two weeks. The majority of the first week will be dedicated to wave one, with the second and third waves taking place the week after. You will work on wave one as a pair, and then complete waves two and three individually.
The primary learning goals in this wave are writing unit tests for JavaScript with Jasmine, and program/code design. What we mean by program design is that the specific approach to implementing your Tic-Tac-Toe game's logic will be up to you.
The overarching goal with the program design requirement is for you to spend more time at the beginning of the project thinking about what functionality the application needs, how that can be split up into specific objects and functions, and what the inputs and outputs of those functions are.
This might seem like an unwarranted distraction from diving right into the code when you're under such time constraints. But a great deal of time can be saved by avoiding costly refactors if it turns out that your initial approach won't allow you to achieve certain requirements. The more complex the application's logic is, the more difficult and time-consuming it will be to rework that logic after it has been written.
For this project you'll need to create your own users stories as a pair, based on your understanding of the Tic-Tac-Toe. For some examples on how user stories work, check out the project requirements from bEtsy.
- Some of your stories will likely map 1-to-1 to individual functions, while others might describe certain aspects of how a single function should behave.
- Because the code you're writing for wave one is the "business logic" of a Tic-Tac-Toe game, the human users of your application will not be interacting with it directly. Instead, the "users" you're writing stories for will be other code in your project -- Jasmine tests or Backbone Views.
- For the first wave you should implement the Tic-Tac-Toe game with the "object-oriented" style used for the Scrabble project.
- Any constructor functions you create should not take arguments. This is only to minimize the work needed to later convert your code into a Backbone Model.
You should strive to follow the BDD approach when building this application. Whenever you decide that a new function is necessary to implement one or another feature, you should begin by writing tests for that function.
- Every function in your application should have at least two tests
- All tests should pass
- We don't have any code coverage tool setup for this project, but if you have every function tested then it should be essentially 100%
In this wave you will convert your existing Tic-Tac-Toe game code into a Backbone Model and create a Backbone View for rendering and interacting with that model.
More details forthcoming
In this wave you'll connect the Backbone web application you created in the previous wave to an existing Rails API that has standard RESTful CRUD routes.
