Your project has been fully converted over to a standard Angular project, with a fully defined build toolchain ready in a new webpack.config.js file. Note that this conversion is a one-way process, and should only be done if you are ready to take full control of your application's build process.
The build process that remains is actually a standard WebPack based build. We will discuss WebPack builds and how to customize them for your application more in Chapter 9, Build Systems and Optimizations.
