🚀 Quick Start

import { useState } from 'react';
import { ReactPhotoEditor } from 'react-photo-editor';

function App() {
  const [file, setFile] = useState();
  const [showModal, setShowModal] = useState(false);

  // Show modal if file is selected
  const showModalHandler = () => {
    if (file) {
      setShowModal(true);
    }
  };

  // Hide modal
  const hideModal = () => {
    setShowModal(false);
  };

  // Save edited image
  const handleSaveImage = (editedFile) => {
    setFile(editedFile);
    // Do something with the edited file
  };

  const setFileData = (e) => {
    if (e?.target?.files && e.target.files.length > 0) {
      setFile(e.target.files[0]);
    }
  };

  return (
    <>
      <input type='file' onChange={(e) => setFileData(e)} multiple={false} />

      <button onClick={showModalHandler}>Edit Photo</button>

      <ReactPhotoEditor
        open={showModal}
        onClose={hideModal}

⚠️ Migration Guide

Migrating from v2.x to v3.0.0

Breaking Changes

• CSS Import Removed: The CSS file import (import 'react-photo-editor/dist/style.css') is no longer required
• Tailwind CSS Configuration: No longer need to add './node_modules/react-photo-editor/dist/*.js' to your Tailwind config
• Changed canvas class name and id: The class name and id for the canvas element have been changed from canvas to rpe-canvas for better consistency with the rest of the project. Make sure to update your usage accordingly.

  const handleSave = async () => {

    // Do something with the edited file
  };

  return (
    <div>
      <canvas ref={canvasRef} />

      <div>
