A pretty good and effective way to create a video placeholder from Youtube or Vimeo using a high-res image.
If you don't know, when an iframe is rendered from browser, it blocks its parse because it isn't a non-blocking script. This isn't so good to your user, no?. With this react component, the iframe just will be loaded when the user click on play.
Installing this component is very easy and it has just one dependency: React. So, you have a lot of options to do that:
Using NPM the quickest way
$ npm install --save react-video
$ bower install --save react-video
