I'm yet to encounter a good example of generated boiler-plate. Every tool that spews out generated code is annoying to work with and you end up having to delete a bunch of files that don't apply.
Better frameworks encapsulate code-generation in a function calls and better abstractions.
1. files that you had to delete?
2. code generation in a function call?
3. better abstraction?
ng generate route 'about-page'
The reason it's terrible is that it makes various assumptions about the naming of your files and project structure, which inevitably break things if they're don't match.
A good example of a better abstraction (a.k.a function call) is the [2] "nuxt" package. In this framework you don't need to generate a route, you just add a file to the '/pages' directory and the framework maps it to a route for you. It's a pleasant and simpler experience.
The earliest form of this trend that I can remember was Macromedia Authorware. Drag-n-drop flowchart style of development with optional coding features.
