What is the TypeScript definition for the onDragStart event in React?

The right interface for onDragStart is DragEvent

Please continue reading below to see how to use it or read my guide on using React's events with TypeScript.

Interface

interface DragEvent<T = Element> extends MouseEvent<T, NativeDragEvent> {
    dataTransfer: DataTransfer;
}

Full example

import React, { DragEvent } from 'react';

const ButtonComponent = () => {
  const handleDragEvent = (e: DragEvent<HTMLDivElement>) => {
    e.preventDefault();
    // Do something
  };

  return <div onDragStart={handleDragEvent}>Drag me!</div>;
};

export default ButtonComponent;
