1. Create a new Magento 2 theme by creating a new directory under app/design/frontend/{Vendor}/{theme-name}.
  2. Create a new package.json file in your theme directory and add the following dependencies:
Perl
{
  "dependencies": {
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "@magento/venia-ui": "^2.4.0",
    "@magento/peregrine": "^2.4.0",
    "@magento/pagebuilder": "^1.1.0"
  }
}
  1. Run npm install to install the dependencies.
  2. Create a new JavaScript file in your theme directory and add your React code.
  3. Import the required components from the @magento/venia-ui and @magento/peregrine packages.
  4. Export your React component as the default export.
  5. In your Magento 2 theme directory, create a new layout XML file under app/design/frontend/{Vendor}/{theme-name}/Magento_Theme/layout/default.xml.
  6. Add the following code to your layout XML file:
XML
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
  <head>
    <script src="{Vendor}_{theme-name}::js/main.js"/>
  </head>
  <body>
    <referenceContainer name="content">
      <block class="Magento\Framework\View\Element\Template" name="react" template="{Vendor}_{theme-name}::react.phtml" />
    </referenceContainer>
  </body>
</page>
  1. Create a new template file app/design/frontend/{Vendor}/{theme-name}/Magento_Theme/templates/react.phtml and add the following code:
php
<div id="root"></div>
<script>
  require(['{Vendor}_{theme-name}/js/main'], function () {
    require(['react', 'react-dom', 'your-react-component'], function (React, ReactDOM, YourReactComponent) {
      ReactDOM.render(React.createElement(YourReactComponent), document.getElementById('root'));
    });
  });
</script>
  1. Finally, run php bin/magento setup:static-content:deploy to deploy the static content and load your new React JS theme.
