react-image-appear

ReactJS component to make images appear with transition as they load.

Wraps an img within a placeholder element and adds a gif loader in between. No more ugly-looking progressively loading images!

This project has also been ported to AngularJS 1.x - ng-image-appear.

Installation

via npm

npm install react-image-appear --save

via yarn

yarn add react-image-appear
