    Features

    Chessground is designed to fulfill all lichess.org web and mobile apps needs, so it is pretty featureful.

    • Well typed with TypeScript
    • Fast. Uses a custom DOM diff algorithm to reduce DOM writes to the absolute minimum.
    • Small footprint: 10K gzipped (31K unzipped). No dependencies.
    • SVG drawing of circles, arrows, and custom user shapes on the board
    • Arrows snap to valid moves. Freehand arrows can be drawn by dragging the mouse off the board and back while drawing an arrow.
    • Entirely configurable and reconfigurable at any time
    • Styling with CSS only: board and pieces can be changed by simply switching a class
    • Fluid layout: board can be resized at any time
    • Support for 3D pieces and boards
    • Full mobile support (touchstart, touchmove, touchend)
    • Move pieces by click
    • Move pieces by drag & drop
      • Minimum distance before drag
      • Centralisation of the piece under the cursor
      • Piece ghost element
      • Drop off revert or trash
    • Premove by click or drag
    • Drag new pieces onto the board (editor, Crazyhouse)
    • Animation of pieces: moving and fading away
    • Display last move, check, move destinations, and premove destinations (hover effects possible)
    • Import and export positions in FEN notation
    • User callbacks
    • No chess logic inside: can be used for chess variants
