What builders did you use, did you write your own configs?

In working with frontend projects, I used build tools such as Webpack, Parcel, and Vite. I usually wrote custom configurations for Webpack to optimize the build for specific tasks: setting up loaders for processing styles, images, configuring code splitting, and adding plugins for minification and caching.

Example of a Webpack configuration:

module.exports = {
  entry: './src/index.js',
  output: {
    filename: 'bundle.js',
    path: __dirname + '/dist'
  },
  module: {
    rules: [
      { test: /\.css$/, use: ['style-loader', 'css-loader'] },
      { test: /\.(png|jpg)$/, type: 'asset/resource' }
    ]
  },
  plugins: [
    // plugins for optimization
  ]
};

I also configured Babel and ESLint configs to ensure code compatibility and quality.
