The course begins with a simple question: "What is webpack?" Then you will learn about installing Webpack, configuring it, and adding loaders for CSS, SASS, HTML, and Files.
The course covers cache busting, setting up a dev server, and splitting up your development and production config files. You will learn about multiple Webpack plugins including clean-webpack-plugin, mini-css-extract-plugin, optimize-css-assets-webpack-plugin, terser-webpack-plugin, and html-webpack-plugin.
