Solving Duplicate Styles/Scripts warning

[kaili-kameoka]

I'm using the plugin to generate a static site that I'll transform into a WordPress theme later.
After adding a second page to the plugins array, I'm getting duplicate styles/script warnings. Both pages use the same styles and scripts. Is there a way to solve this?

webpack.config.js

//webpack.config.js
const path = require('path');
const PugPlugin = require('pug-plugin');

module.exports = {
	entry: {
		index: './src/index.pug',
	},
	output: {
		path: path.join(__dirname, 'dist/'),
		publicPath: 'dist/',
		filename: 'assets/js/[name].[contenthash:8].js',
		clean: true
	},
	plugins: [
		new PugPlugin({
			pretty: true,
			extractCss: {
				filename: 'assets/css/[name].[contenthash:8].css'
			}
		}),
		new PugPlugin({
			filename: 'about.pug',
			pretty: true,
			extractCss: {
				filename: 'assets/css/[name].[contenthash:8].css'
			}
		})
	],
	module: {
		rules: [
			{
				test: /\.pug$/,
				loader: PugPlugin.loader
			},
			{
				test: /\.(css|sass|scss)$/,
				use: ['css-loader', 'sass-loader'],
				generator: {
					filename: 'assets/css/[name].phash:8][ext]'
				}
			},
			{
				test: /\.(png|jpg|jpeg|ico)/,
				type: 'asset/resource',
				generator: {
					filename: 'assets/img/[name].[hash:8][ext]'
				}
			},
			{
				test: /\.(woff|woff2|eot|ttf|otf|svg)$/i,
				type: 'asset/resource',
				generator: {
					filename: 'assets/fonts/[name][ext][query]'
				}
			}
		]
	},
	stats: 'errors-only'
};

Hello @kaili-kameoka,

you has wrong Webpack config.

Unlike the html-webpack-plugin, the new PugPlugin(..) must be initialised only once in plugins and all Pug files must be defined in Webpack entry.

Please update pug-plugin to v4.6.0. The new version has some improvements and optimization of options.

const path = require('path');
const PugPlugin = require('pug-plugin');

module.exports = {
  entry: {
    // define all Pug files only here
    index: './src/index.pug',
    about: './src/about.pug',
  },
  output: {
    path: path.join(__dirname, 'dist/'),
    publicPath: '/', // Note: this is the path relative by output.path, or `auto`
    clean: true
  },
  plugins: [
    new PugPlugin({
      pretty: true,
      js: {
        // since pug-plugin v4.6.0 place filename for JS here
        filename: 'assets/js/[name].[contenthash:8].js',
      },
      // since pug-plugin v4.6.0 the 'extractCss' option is renamed to 'css'
      css: {
        filename: 'assets/css/[name].[contenthash:8].css'
      },
    }),
  ],
  module: {
    rules: [
      {
        test: /\.pug$/,
        loader: PugPlugin.loader
      },
      {
        test: /\.(css|sass|scss)$/,
        use: ['css-loader', 'sass-loader'],
        // don't use filename for CSS here, it must be defined by PugPlugin options, see above
        //generator: {
        //  filename: 'assets/css/[name].phash:8][ext]'
        //}
      },
      {
        test: /\.(png|jpg|jpeg|ico)/,
        type: 'asset/resource',
        generator: {
          filename: 'assets/img/[name].[hash:8][ext]'
        }
      },
      {
        test: /\.(woff|woff2|eot|ttf|otf|svg)$/i,
        type: 'asset/resource',
        generator: {
          filename: 'assets/fonts/[name][ext][query]'
        }
      }
    ]
  },
  stats: 'errors-only'
};

Thank You! Think it might have been an old tutorial where I got the config from.
