export default AddProduct

Solution 1

You can crop the image just after selecting the image in front end. For cropping the image these 2 module are best.

1. React-easy-crop
2. React-image-crop.

Integration of these module is also simple.

Solution 2

I've recently blogged about how to do this using react-uploady.

Check out this codesandbox for the full example.

The code uses react-image-crop but its not tied to it in any way, so you can replace it with any other crop solution you desire.

It boils down to:

import React, { useState, useCallback, useRef } from "react";
import ReactCrop from "react-image-crop";
import "react-image-crop/dist/ReactCrop.css";
import Uploady, { withRequestPreSendUpdate } from "@rpldy/uploady";
import UploadButton from "@rpldy/upload-button";
import UploadPreview from "@rpldy/upload-preview";
import cropImage from "./cropImage";

const ItemPreviewWithCrop = withRequestPreSendUpdate((props) => {
  const { url, updateRequest, requestData } = props;
  const [crop, setCrop] = useState({ aspect: 4 / 3 });

  const onUploadCrop = useCallback(async () => {
    if (updateRequest && (crop?.height || crop?.width)) {
      requestData.items[0].file = await cropImage(url, requestData.items[0].file, crop);
      updateRequest({ items: requestData.items });
    }
  }, [url, requestData, updateRequest, crop]);

  return (
    <>
      <ReactCrop
        src={url}
        crop={crop}
        onChange={setCrop}
        onComplete={setCrop}
      />
      <br/>
      <button onClick={onUploadCrop}>Upload Cropped</button>
    </>
  );
});

export default function App() {
  const previewMethodsRef = useRef();

  return (
    <Uploady destination={{ url: "[upload-url]" }} multiple={false}>
      <br />
      <UploadButton>Select File</UploadButton>
      <br />
      <UploadPreview
        PreviewComponent={ItemPreviewWithCrop}
        previewComponentProps={{ previewMethods: previewMethodsRef }}
        previewMethodsRef={previewMethodsRef}       
      />
    </Uploady>
  );
}

It will show the selected file in the crop area with fixed 4/3 aspect ratio (just an example).
