I get the following Console error, request you to help me on this, Let me know if you need any other info.

Uncaught ReferenceError: process is not defined

    at Object.options.factory (react refresh:6:1)

    at Object.options.factory (react refresh:6:1)

I get this above error, It's a simple experiment to upload the file.

ReactUploader.js

var ReactS3Uploader = require('react-s3-uploader');
    
<ReactS3Uploader
    signingUrl="http://127.0.0.1:5000/create-presigned-s3-url/"
    signingUrlMethod="GET"
    accept="image/*"
    s3path=""
    preprocess={this.onUploadStart}
    onSignedUrl={this.onSignedUrl}
    onProgress={this.onUploadProgress}
    onError={this.onUploadError}
    onFinish={this.onUploadFinish}
    // signingUrlHeaders={{ additional: headers }}
    // signingUrlQueryParams={{ additional: queryparams }}
    signingUrlWithCredentials={ true }      // in case when need to pass authentication credentials via CORS
    uploadRequestHeaders={{ 'x-amz-acl': 'public-read' }}  // this is the default
    contentDisposition="auto"
    scrubFilename={(filename) => filename.replace(/[^\w\d_\-.]+/ig, '')}
    server=""
    inputRef={cmp => this.uploadInput = cmp}
    autoUpload={true}
    />

export default ReactS3Uploader;

Had the same issue while using Create React App. Switch to webpack to fix the problem.

I think webpack auto polyfills in Node packages (like process). While CRA is made for front-end only. (react-s3-uploader probably comes with those packages since it is meant to handle both server and front-end in 1 package).
