This is a game of TicTacToe based on the React Tutorial, but utilizing Xstsate for state management. The first commit is the basic tutorial code for the game with state managed by the components. Commits after that are when Xstate was introduced.
To avoid "state explosion", we only model game states and not the state of the board itself. The squares of the board are part of the context for the state machine.
The states of the game are:
- Start
- xTurn - X player's turn
- oTurn - O player's turn
- Game over - a transient state used to determine the winner
- xWinner - X wins the game
- oWinner - O wins the game
- noWinner - No winner ("cat's game")
The original React Tutorial allowed players to traverse through the history, but this isn't easily modeled in Xstate. Individual state nodes can have history, but not the entire machine itself. Instead of overcomplicating this simple example, the history buttons were replaced with a Start Over button that can restart the game after it ends.
This project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
