Have you ever had to deal with architecture, write modules, develop from scratch? Are you familiar with Feature-Sliced Design (FSD)?

Yes, I have had to develop architecture and write modules from scratch. In such cases, it is important to immediately define a clear project structure, divide responsibilities among components, and ensure ease of scaling.

Regarding Feature-Sliced Design (FSD), I am familiar with this approach. FSD suggests breaking down the frontend application into layers and features, where each feature is an independent module with clearly defined boundaries. This helps improve support and extendability of the code.

An example structure according to FSD:

src/
  app/          # global settings and initialization
  pages/        # application pages
  features/     # individual functionalities
  entities/     # business objects
  shared/       # common components and utilities

This approach simplifies navigation and reduces coupling between modules.
