uploader

Step 1: cd to my app npm install cloudinary-react

Step 2: Navigate to App.js Add Upload Widget method

openUploadWidget = () => {
    var comp = this;
    window.cloudinary.openUploadWidget({ cloud_name: "<cloud_name>", upload_preset: "<upload_preset>", sources:['local','url','facebook']}, 
          function(error, result){

            if(result)            
              component.setState({ publicId: result[0].public_id });
        });
  }

Step 3: In App.js, pass publicId and uploadWidget to our component

<Button openUploadWidget={this.openUploadWidget} publicId={this.state.publicId}/>

Step 4: In Button.js eject props to const proptypes

const proptypes = {
	publicId: PropTypes.string,
	openUploadWidget: PropTypes.func	
}

Step 5: In Button.js import { Image } from 'cloudinary-react';

Step 6: Creat upload preset on cloudinary console. Paste cloud name and preset to upload widget function. Add cloudname to Image tag on Button.js

Step 7: Play around with SDK components

For example, in App.js, add-

 <span className={'pads'}>
 	<Image cloudName="<cloud_name>" publicId={this.state.publicId} effect="blur:300" width="300">
        	<Transformation angle="45"/>
        </Image>
 </span>
<span className={'pads'}>
	<Image cloudName="<cloud_name>" publicId={this.state.publicId} >
		<Transformation width="300" effect="sepia" crop="scale"/>
        </Image>
</span>
<span className={'pads'}>
	<Image cloudName="<cloud_name>" publicId={this.state.publicId} >
		<Transformation width="300" effect="grayscale" crop="scale"/>
	</Image>
</span>
