Ionic should not install all dependencies unless instructed to

[Baraka-Mugisha]

I would like to point out that it is unfortunate that the ionic start command automatically executes the npm install command to install all npm dependencies. Given also that the options for skipping dependencies does not work

In my opinion, the command's main purpose should be to generate code, not handle dependency installation. It would be more in line with the single responsibility principle if the command focused solely on code generation.

Running npm install is a simple command that we can manually execute after generating the project. I mention this because the automatic execution of npm install during ionic start can significantly increase the execution time, especially on slow networks. This can be frustrating, especially when we need to run the command multiple times to explore different templates or options.

It's important to note that generating code does not necessarily mean that we will immediately execute it. Separating the dependency installation step from the code generation step would provide more flexibility and control over the development process
