## Overview

This is a full-stack notes application: users register or log in, create and manage notes, browse public or shared notes, and grant or revoke access; they can also update their profiles. The frontend routes and feature modules lead into entity data hooks and API clients, while the Spring backend exposes controllers, applies service-layer rules, and persists through repositories. The sampled source confirms note, authentication, profile, and access-management behavior; some frontend API-to-backend wiring and unsampled controller/service details are inferred only from the module structure, so uncertain internal links are omitted.

Main entry points: [`frontend/src/shared/api/axiosInstance.ts`](https://github.com/anufrievalex2006/my-notes-app/blob/main/frontend/src/shared/api/axiosInstance.ts) (HTTP client), [`frontend/src/widgets`](https://github.com/anufrievalex2006/my-notes-app/tree/main/frontend/src/widgets) (Page widgets), [`backend/src/main/java/com/notesapp/backend/repos`](https://github.com/anufrievalex2006/my-notes-app/tree/main/backend/src/main/java/com/notesapp/backend/repos) (Data repositories), [`backend/src/main/java/com/notesapp/backend/services/AuthService.java`](https://github.com/anufrievalex2006/my-notes-app/blob/main/backend/src/main/java/com/notesapp/backend/services/AuthService.java) (Authentication service)
