Webpack Dev Server

webpack-dev-server (WDS) is a development server for Webpack that provides live reloading, hot module replacement (HMR), and fast builds for frontend development. It serves your Webpack-compiled files from memory, avoiding the need to write them to disk, which speeds up development.

// webpack.config.js
    module.exports = {
    mode: 'development',
    devServer: {
        port: 8081,
    },
};
