import { ButtonHandle } from "@/components/button-handle";
import { BaseNode } from "@/components/base-node";

const onClick = () => {
  window.alert(`Handle button has been clicked!`);
};
 
const selector = (connection: ConnectionState) => {
  return connection.inProgress;
};
 
const ButtonHandleDemo = () => {
  const connectionInProgress = useConnection(selector);
 
  return (
    <BaseNode>
      Node with a handle button
      <ButtonHandle
        type="target"
        position={Position.Bottom}
        showButton={!connectionInProgress}
      >
        <Button
          onClick={onClick}
          size="sm"
          variant="secondary"
          className="rounded-full"
        >
          <Plus size={10} />

  );
};
 
export default ButtonHandleDemo;

2. Connect the component with your React Flow application.

import { Background, ReactFlow } from "@xyflow/react";
 
import SourceHandleDemo from "./component-example";
 
const defaultNodes = [
  {
    id: "1",
    position: { x: 0, y: 0 },
    data: { label: "Node" },
    type: "sourceHandleDemo",
  },
];
 
const nodeTypes = {
  sourceHandleDemo: SourceHandleDemo,
};
 
export default function App() {
  return (
    <div className="h-full w-full">
      <ReactFlow defaultNodes={defaultNodes} nodeTypes={nodeTypes} fitView>
        <Background />
      </ReactFlow>
    </div>
  );
}
