This is a Chess project implemented in TypeScript. It includes move validator functions to validate legal chess moves.

To get started with this project, follow these steps:

• Clone the repository to your local machine:

  git clone https://github.com/barrymun/chess.git

• Run the setup script:

  yarn run setup

• Create a server/.env/ file and include the following:

  CORS_ORIGIN="http:https://localhost:3000"

  Create a client/.env.development file and include the following:

  REACT_APP_API_URL="http:https://localhost:3001"

  If you want to build the client code you will need a client/.env.production file.

• Navigate to the project directory:

  cd chess

• Build the common module:

  yarn workspace common build

• Install the required dependencies:

  yarn install

• Start the Express.js server with Docker:

  yarn docker-up

  Alternatively the express.js server can be started without using Docker:

  yarn workspace server build
  yarn workspace server start

• Start the react development server:

  yarn workspace client start

• Open your web browser and visit http:https://localhost:3000.

The project includes TypeScript functions to validate chess moves. These functions can be found in common/src/move-validator.ts. You can use these functions to ensure that the moves made in the game adhere to the rules of chess.

jest (specifically ts-jest) is used for testing. Most of the tests can be found in the common package. Run the following command from the root directory:

yarn test

If you'd like to contribute to this project, feel free to fork the repository and submit a pull request with your changes. Make sure to follow the coding standards and conventions used in the project.

• check if king is in check
• check if there is a checkmate or stalemate (similar logic) (sample stalemate: https://www.chess.com/forum/view/more-puzzles/stalemate-in-10-moves)
• pawn promotion logic
• castling logic
• highlight areas on piece grab that the selected piece can move to (legal moves dots)
• add break; statements in the direction loop checks to exit early
• add break; statement from queen moves early if diagonal checked and move is diagonal as there would be no need to then check the straight moves
• problem with rook move logic - can move from g5 to a4
• show where the last piece was moved from and to with colours?
• have the game run through many sample games in the chess db
• integrate the stockfish JS engine or something along these lines: https://github.com/nmrugg/stockfish.js
• preserve the game state before a reload (singleplayer)
• multiplayer (websockets & redis)
• add usernames to multiplayer and specific player matching other than random matching
• make the legal dots optional (player can toggle this setting on and off)
• lots of test cases
• game over (reason, winner, etc.) modal
• add sound effects
• different colour themes for different boards and pieces
• show all of the moves made so far
• show moves made so far as algebraic notation
• validate the chess board to prevent cheating (based on the moves made so far?)
• show the pieces that have been captured
• show the value of the pieces that have been captured
• fix min width settings to use % rather than the set amount of 100px (mobile)
• timed moves (will be added as part of a separate game mode)
• fix move-history component min width to prevent "jumping" issue
• fix grab piece issue where the "image" itself is "grabbed" (desktop)
• disable right click on piece grab
• change favicon and title
• fix move history text for promoted pawns
• check to see if the user has deleted their playerId from localStorage?
• make previous games viewable
• install spell checker (cspell)
• support internationalisation (i18n)
