Help needed

Hi Folks,

I need advice for my SaaS idea.

What might by best way to processed when I need methodology which will generate JavaScript code (compiled code) based on different inpunts which will be provided by client in the web UI?

Closest to what I can think of is Google Tag Manager - code implemented once and then changes are deployed from web app (tag manager) without needed to touch code again.

Is there some particular nocode tool or another methodology which you can recommend please?
