How to structure nestjs project [closed]

How to structure an event organization web application?

I’m new to programming projects from scratch, and I’ve started creating an event organization web application. I’m confused about how to divide the functionality.

Application Requirements:

  1. User:

    • Can see upcoming events
    • Can choose an existing group to enroll in

  2. Admin:

    • Can create and manage groups for an event
    • Each group represents an activity for the event (presentation, song, dance, etc.)

My Questions:

  1. What is the right way to define modules for this nestjs project

  2. How to define whick entities shoould i create

I would appreciate any guidance on the architecture and role division for this type of application.

I haven’t started creating modules yet, was a bit scared to mess things up from the start
