Installation

Install via npm

npm install --save react-cropper

You need cropper.css in your project which is from cropperjs. Since this project have dependency on cropperjs, it located in /node_modules/react-cropper/node_modules/cropperjs/dist/cropper.css or node_modules/cropperjs/dist/cropper.css for npm version 3.0.0 later

Breaking Change (version >= 2.0.0)

1. Support for ref has been removed. Use the onInitialized method to get the cropper instance. Added back ref support in 2.1.0.
2. To set initial aspect ratio, instead of using aspectRatio use initialAspectRatio.
3. Props data, canvasData and cropBoxData are directly passed on to cropperjs and their respective setters are not called as earlier.
4. React Cropper now does not try to use/execute moveTo as earlier. Directly use the moveTo method from the cropper instance.
5. React Cropper does not depend on @types/react-cropper and provides its own types. Please uninstall/remove @types/react-cropper as they might 'cause issues.

Quick Example

import React, { useRef } from "react";
import Cropper from "react-cropper";
import "cropperjs/dist/cropper.css";

const Demo: React.FC = () => {
  const cropperRef = useRef<HTMLImageElement>(null);
  const onCrop = () => {
    const imageElement: any = cropperRef?.current;
    const cropper: any = imageElement?.cropper;
    console.log(cropper.getCroppedCanvas().toDataURL());
  };

  return (
    <Cropper
      src="https://raw.githubusercontent.com/roadmanfong/react-cropper/master/example/img/child.jpg"
      style={{ height: 400, width: "100%" }}
      // Cropper.js options
      initialAspectRatio={16 / 9}
      guides={false}
      crop={onCrop}
      ref={cropperRef}
    />
