Hugo as a frontend for a Webapp?

I am wondering whether I can use Hugo as a frontend for my web app. I developed an app backend and now need interaction with the user. The frontend consists already of static sites. The site’s functionality comes from AWS API calls and JS. However, it is quite cumbersome always to create new pages for new features. I think a static site generator might be the best option, but I don’t know where to start. I used Hugo in the past quite extensively, but only for a usual blog. Does anyone here have experience with Hugo as a frontend or can point me in the right direction? Many thanks!
