We'll be using it though, because it makes getting started a lot easier, and promotes a modular application structure.
The application generator is optional because you don't need to use this tool to create apps that use Express, or construct Express apps that have the same architectural layout or dependencies.
NPM can also be used to (globally) install the Express Application Generator, a handy tool for creating skeleton Express web apps that follow the MVC pattern. Express is then installed by NPM as a dependency of your individual Express web applications (along with other libraries like template engines, database drivers, authentication middleware, middleware to serve static files, etc.) Node and the NPM package manager are installed together from prepared binary packages, installers, operating system package managers or from source (as shown in the following sections). The Express development environment includes an installation of Nodejs, the NPM package manager, and (optionally) the Express Application Generator on your local computer.

If the Projects feature is enabled, this identifies which project should be started.
If the Projects feature is not enabled, this sets the flow file you want to work with. When you deploy your changes, the flows are then started. This allows you to open the flows in the editor and make changes without the flows running. Starts Node-RED without starting the flows. Sets the TCP port the runtime listens on. Node-RED can be started using the command node-red. This by providing the flow file name as argument to the node-red command.
