const path = require('path')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const MiniCssExtractPlugin = require('mini-css-extract-plugin')

module.exports = {
  entry: {
    'pages/main/index' : './src/pages/main/index.js',
    'pages/pets/pets' : './src/pages/pets/pets.js'
  },
  output: {
    filename: '[name].js',
    path: path.resolve(__dirname, 'dist'),
    publicPath: '',
    assetModuleFilename: (pathData) => {
      const filepath = path
        .dirname(pathData.filename)
        .split("/")
        .slice(1)
        .join("/");
      return `${filepath}/[name].[hash][ext][query]`;
    },
  },
  mode: 'development',
  module: {
    rules: [
      {
        test: /\.html$/i,
        loader: "html-loader",
      },
      {
        test: /\.s[ac]ss$/i,
        use: [
          MiniCssExtractPlugin.loader,
          "css-loader",
          "sass-loader",
        ],
      },
    ],
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: './src/pages/main/index.html',
      filename: './pages/main/index.html',
      excludeChunks: ['pages/pets/pets']
    }),
    new HtmlWebpackPlugin({

      filename: './pages/pets/pets.html',
      chunks: ['pages/pets/pets']
    }),
    new MiniCssExtractPlugin({
      filename: '[name].css',
      chunkFilename: "[id].css"
    }),
  ],
