Tutorial to integrate the react.js into shopify theme

Step

note: you have to run theme watch command first

1. Download the shopify theme with theme kit theme download
2. Convert the theme as webpack theme $ npm init
3. Install react, react-dom and webpack package $ npm install --save react react-dom and $ npm install --save-dev @babel/core @babel/preset-env @babel/preset-react babel-loader core-js webpack webpack-cli webpack-merge
4. Create ajax-cart-side.jsx in scripts folder(create scriptsfolder in the root of the theme)
5. Create .babelrc file in the root of theme file

{
   "presets":[
      [
         "@babel/preset-env",
         {
            "useBuiltIns":"usage",
            "corejs":3
         }
      ],
      "@babel/preset-react"
   ]
}

6. Create webpack.common.js webpack.prod.js webpack.dev.js files in the root of theme file

webpack.common.js

const path = require("path")

module.exports = {
  entry: {
    'ajax-cart-side': "./scripts/ajax-cart-side.jsx"
  },
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        exclude: /node_modules/,
        use: ["babel-loader"]
      }
    ]
  },
  output: {
    filename: "[name].bundle.js",
    path: path.resolve(__dirname, "assets")
  }
}

webpack.prod.js

const merge = require("webpack-merge")
const common = require("./webpack.common.js")

module.exports = merge(common, {
  mode: "production"
})

webpack.dev.js

const merge = require("webpack-merge")
const common = require("./webpack.common.js")

module.exports = merge(common, {
  mode: "development",
  devtool: "inline-source-map",
  watch: true
})

8. Update the package.json file with this scripts

  "scripts": {
    "dev": "webpack --config webpack.dev.js --progress --color",
    "build": "webpack --config webpack.prod.js --progress --color"
  }

8. Finally, npm run dev Run!!!
9. You can use React.js in assets/ajax-cart-side.js

For example:

import React from "react"
import ReactDom from "react-dom"

const Test = () => {
	return <div>This is tutorial to integrate react.js into shopify theme with webpack</div>
}

const root = document.getElementById('cart__drawer_items');
ReactDom.render(<Test />, root);

Issues: when you install it, may a few issues will happen. In that case, npm link webpack npm install webpack or change the merge like this const { merge } = require('webpack-merge'); in webpack.dev.js and webpack.prod.js

Error: Cannot find module 'v8-compile-cache'

In this case, you have to install v8-compile-cache module with npm install --save v8-compile-cache
