Tic Tac Toe using React - by Maulik Suchak

• Project: Tic Tac Toe game
• Time Taken: ~6hrs
• Language/Frameworks: JavaScript(with React) + SCSS

Howdy! 👋

Hey there, this is Maulik Suchak. This is my version of Tic Tac Toe

Features Implemented as MVP

• You can play this against computer.
• Displays the winner in the end in a popup.
• Total wins counter for both Players.
• Ability to make n x n table (TODO: winning logic is only for 3 x 3 right now)

Possible Enhancements

• [UX] Store "score" in the local storage so it doesn't go back to 0 after browser refresh.
• [UX / Tech] More smarter computer move instead of just letting it randomly choose one
• [UX] Multi-player realtime (could use Socket.io)
• [Tech] Better SCSS organziation by using mixins, variable, etc.
• [UX / Tech] Graceful degradation to support non-modern browser.

Setup & Development

Prerequisite

• Make sure you have node installed -- recommended 6.4.1.
• Once you have a node installed, run npm install in this repo to get your dependencies.
• (optional) npm run build to create build folder.

In the project directory, you can run:

npm start

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.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build

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.

Description / Data Flow / Approach

• This project was bootstrapped with Create React App. Reason: wanted to move quickly since this structure will give me minimum things I'd need to create a MVP.
• It draws n x n table to begin with.
• Assigns click event to all cells and X (player A) takes the first turn.
• I generate random number of the cell (0 - 8) for computer to make move. This logic has to be updated if we want to finish implementing n x n.
• Tried to use minimal CSS to move quickly. Used SCSS to create better org structure.

Some Manual Test Cases

Could write following automated unit tests.

Unit tests

• Computer makes a move after Player A finishes the move
• Automated next move of computer
• Shows banner when game ends

Thank you!
