Composer

Set the minimum-stability in your composer.json to dev 2. This widget compile react bundle from npm react and react-dom packages using browserify and uglify-js BUT since composer run scripts only for root composer.json, need to add the following lines to your composer.json: ```composer ... "scripts": { "regenerate_react_bundle": [ "vendor/b-tokman/yii2-react/build-bundles.sh" ], "post-install-cmd":[ "@regenerate_react_bundle", ], "post-update-cmd": [ "@regenerate_react_bundle", ] ..., _(*3)

This way composer will run browserify to create react-bundle.js and uglifyjs to minify it, each time after upgrade or install

2. Then run 

```sh
  $ composer require b-tokman/yii2-react

Composer will download yii2-react package with all dependenices, then npm will download react and react-dom npm packages and scripts will compile it., _(*4)
