    Webpack & Tailwind CSS Setup

Create your package.json

npm init -y

Create your src folder

Create a folder called src and add an empty index.js file. The code that webpack compiles goes in here including any Javascript modules and the main Tailwind file.
Install Tailwind

npm i -D tailwindcss

Install Webpack & Loaders

npm i -D webpack webpack-cli webpack-dev-server style-loader css-loader postcss postcss-loader postcss-preset-env

Create webpack.config.js in the root and add this to it...

const path = require('path')

module.exports = {
  mode: 'development',
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'bundle.js',
  },
  devServer: {
    static: {
      directory: path.resolve(__dirname, 'dist'),
    },
    port: 3000,
    open: true,
    hot: true,
    compress: true,
    historyApiFallback: true,
  },
  module: {
    rules: [
      {
        test: /\.css$/i,
        include: path.resolve(__dirname, 'src'),
        use: ['style-loader', 'css-loader', 'postcss-loader'],
      },
    ],
  },
}


Add Tailwind Directives

Create a style.css in your src folder and add these 3 lines
@tailwind base;
@tailwind components;
@tailwind utilities;


Tailwind Config File

run the following command to generate your tailwind.config.js file and add this to it
module.exports = {
  content: ['./dist/*.html'],
  theme: {
    extend: {},
  },
  variants: {
    extend: {},
  },
  plugins: [],
}


PostCCSS Config File

Create a file in the root called postcss.config.js and add this
const tailwindcss = require('tailwindcss');
module.exports = {
  plugins: [
    'postcss-preset-env',
    tailwindcss
  ],
};

Add this line to your src/index.js

import './style.css';

Create a dist/index.html file and add this

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Webpack App</title>
  </head>
  <body>
    <h1 class="text-4xl text-blue-700">My Webpack + Tailwind App</h1>
    <script src="bundle.js"></script>
  </body>
</html>

Add scripts to package.json

Add the following to your package.json file
"scripts": {
    "dev": "webpack serve",
    "build": "webpack"
  },

Running your app

To build once and create your dist/bundle.js file, run
npm run build

To run your webpack server
npm run dev

You now have Webpack setup along with Tailwind CSS
