Docs

You can find the full documentation here.

Setup:

• Just install the package and import the component in your project, like shown above.
• Don't forget to include the stylesheet: <br> import 'vue3-chessboard/style.css';

Chessboard config

You can pass a config object to the chessboard component to modify the board to your needs, as a prop (:board-config). The config object is optional and will be merged with the default config. The default config is based on the lichess board config. Additionally custom callback functions can be passed to the component. For example a custom function can be run on piece selection or after each move.

API

The chessboard component provides an API to interact with the chessboard. The API is accessible via the board-created event. The event will be emitted when the chessboard is created and ready to use.

Available methods:

For a full list of available methods please visit the documentation.

Custom Events

You can listen for events on the chessboard component. The following events are available:

• boardCreated - Emitted when the chessboard is created and the API is ready to use
• checkmate - Emitted when a player is checkmated

• draw - Emitted when the game is drawn
• check - Emitted when a player is checked
• promotion - Emitted when a player promotes
• move - Emitted when a player makes a move
