  disableStyleReset: false, // false by default
  disableEditing: false, // false by default
  // snapPoints?: SnapPoint[];
  // snapGridSize?: number;
  // snapThreshold?: number;
  // snapWithinElements?: HTMLElement[];
  // handleSelector: '.somethingInsideElement', // only clicks here in element can drag
  mouseDownCallback: function (element) {}, // optional
  touchStartCallback: function (element) {}, // optional
  mouseMoveCallback: function (element) {}, // optional
  touchMoveCallback: function (element) {}, // optional
  mouseUpCallback: function (element) {}, // optional
  touchEndCallback: function (element) {}, // optional

    alert("left offset " + left + " and top offset " + top);
  },

Development notes

Edit the TS files! The JS files are generated from the TS files.

To automatically generate the JS files and do type checking against the .d.ts files while developing from within this repo:

yarn global add typescript
# npm install --global typescript
npx tsc --init # or tsc --init # creates tsconfig.json
tsc

To run a demo on http://localhost:5173/ :

yarn
yarn demo
# npm install; npm run build; vite;

To get the sha384-... values to put into integrity="..." of script tags:

bash get-integrity.sh;
