This is our directory structure for a Nest.js SPEED backend application. Let's break down each of the main directories and their likely purposes:

1. analyst:

   • interfaces: TypeScript interface definitions for analysts.
   • schemas: Data schemas/models for analyst-related data.

2. auth:

   • dto: Data Transfer Object (DTO) classes for authentication data transfer.
   • schemas: Schemas/models for authentication data.

3. moderator:

   • interfaces: TypeScript interfaces for moderators.
   • schemas: Schemas/models for moderator-related data.

4. speed:

   • interfaces: TypeScript interfaces for the SPEED module.
   • schemas: Schemas/models for SPEED module data.

5. Files:

   • app.controller.spec.ts: Unit tests for the controller.
   • app.controller.ts: Controller handling HTTP requests.
   • app.module.ts: Main module configuration.
   • app.service.ts: Business logic and data manipulation.
   • auth.guard.ts: Authentication guard for route protection.
   • main.ts: Application entry point.

This directory structure seems to follow a typical Nest.js application layout, with separate directories for different modules (analyst, auth, moderator, and speed), as well as the core application files (controller, module, service) and the test files.
