export function App() {
  const [images, setImages] = React.useState([]);
  const maxNumber = 69;
 
  const onChange = (imageList, addUpdateIndex) => {
    // data for submit
    console.log(imageList, addUpdateIndex);
    setImages(imageList);
  };
 
  return (
    <div className="App">
     
      <h1>Therichpost.com</h1>
     
   
      <div className="container">

        dataURLKey="data_url"
      >
        {({
          imageList,
          onImageUpload,
          onImageRemoveAll,
          onImageUpdate,
          onImageRemove,
          isDragging,
          dragProps,
        }) => (
          // write your building UI
          <div className="upload__image-wrapper">
            <div className="mainbtndiv">
              <button className="btn btn-primary"
                style={isDragging ? { color: 'red' } : undefined}
                onClick={onImageUpload}
                {...dragProps}

              </button>
              
              <button className="btn btn-danger" onClick={onImageRemoveAll}>Remove all images</button>
            </div>
            {imageList.map((image, index) => (
              <div key={index} className="image-item mt-5 mb-5 mr-5">
                <img src={image['data_url']} />
                <div className="image-item__btn-wrapper">
                  <button className="btn btn-primary" onClick={() => onImageUpdate(index)}>Update</button>
                  <button className="btn btn-danger" onClick={() => onImageRemove(index)}>Remove</button>
                </div>
              </div>
            ))}
          </div>
        )}
