Using Bootstrap Studio with Express (node) (& some templating engine)

Greetings all.

I am using bootstrap studio with the intention of easily designing my UI as to not have to worry about the nitty-gritties of the front-end dev (UI specific), naturally some front-end dev (JS wise) is required.

My intention:

to use my Express app as my back-end which will be serving my bootstrap designed UI. If I were to "import" my bootstrap designed UI into a templating engine (Jade/Pug) for maybe easier maintenance in the future, what are things I need to keep in mind, look out for, etc?

Question:

Last time I used Webflow, and had to take easy html page, convert it into jade/pug, and add to my express project which was quite tedious for a 7 page site, can I expect to do the same here aswel?
