When building whiteboard and annotation features with Konva.js, effective text management is essential for user experience. Consider these tips for handling text input and styling:

  • Use a native HTML input or textarea for editing, then update the Konva Text node when editing is complete;
  • Set clear font size, family, and fill color to ensure text is readable on any background;
  • Adjust the input field's position and size to match the text node for seamless editing;
  • Enable dragging on text nodes so users can move annotations freely;
  • Listen for double-click events to trigger editing, and handle Enter/Escape keys for saving or canceling edits;
  • Always redraw the layer after text changes to reflect updates immediately.
