React Magento 2 implementation. This Simple module explains how to add and use React Components with Magento 2 and forgot about Knockout/JQuery Magento 2 UI.

It is not PWA or headless implementation which is impossible to use with existing web site and also they have issue with magento 2 API performance - to slow. This implementation is High Performance Hybrid React integration with magento2 (with magento 1 also easy to use) it uses inline json directly from the page. The same approach used in magento 2 backend and frontend checkout, color swatches by default. Also can use Ajax http call to fetch data (not the best solution magento API is slow and will increase load on your beckend server). Or you can use my future project "Microservicess magento" to fetch data. Our simplest magento 2 module use WebPack for React Components Compilation and automatic static content deployment into magento pub/static folder.

You can develop React component even without magento instalation at all. You can just copy your component inside magento Module and add some fixes into sources to work with Require JS and use React Component as Magento UI component.

Install Node.JS (https://github.com/nodesource/distributions/blob/master/README.md) From the extension root (React/React) folder run:

npm install
npm start

Web Puck compiles everything automatically into React/React/view/base/web/js/index_bundle.js and deploys to pub/static without running static:deploy ssh command. LiveReload Plugin will reload magento 2 pages automatically (not recommended solution by React Community. F5 more reliable solution). What you need just disable Cache of your browser during development. Also You can disable caching for single react bundle file via Nginx config.

This project aims to solve the case where you want assets served by your Magento app server, but still want reloads triggered from webpack's build pipeline.

Add a script tag to your page pointed at the livereload server

<script src="http://localhost:35729/livereload.js"></script>

For development purpose better disable browser caching (https://www.technipages.com/google-chrome-how-to-completely-disable-cache)

Disable react bundle caching for development purpose using Nginx (not tested yet):

location ~ index_bundle\.js {
    add_header Cache-Control no-cache;
    expires 0;
  }
