## Overview

#### Purpose and entry points
This is a MERN movie-management and viewing application: a React/Vite client consumes an Express API for movies, genres, users, authentication, and uploads. Backend startup is `backend/index.js`; frontend bootstrap and application composition are `frontend/src/main.jsx` and `frontend/src/App.jsx`.

#### Backend HTTP layer
Express routes divide the API by domain: movies, genres, users, and uploads in `backend/routes/moviesRoutes.js`, `backend/routes/genreRoutes.js`, `backend/routes/userRoutes.js`, and `backend/routes/uploadRoutes.js`. These route modules are the principal boundary between the SPA and server-side application logic.

#### Controllers and request pipeline
Domain controllers implement API operations and coordinate persistence: `backend/controllers/movieController.js`, `backend/controllers/genreController.js`, and `backend/controllers/userController.js`. Shared middleware handles asynchronous controller failures, identity validation, and authorization before controllers execute: `backend/middlewares/asyncHandler.js`, `backend/middlewares/checkId.js`, and `backend/middlewares/authMiddleware.js`.

#### Persistence and authentication
MongoDB is the persistence runtime, initialized through `backend/config/db.js`. Mongoose-style domain records define the core data model in `backend/models/Movie.js`, `backend/models/Genre.js`, and `backend/models/User.js`. Authentication tokens are created in `backend/utils/createToken.js` and enforced at protected-route boundaries by `backend/middlewares/authMiddleware.js`.

#### Client state and API integration
The React client uses Redux Toolkit state plus an API layer. Store assembly is in `frontend/src/redux/store.js`; authentication state is maintained by `frontend/src/redux/features/auth/authSlice.js`; movie-specific local state is in `frontend/src/redux/features/movies/moviesSlice.js`. API endpoints are centralized through `frontend/src/redux/api/apiSlice.js` and domain endpoint modules such as `frontend/src/redux/api/movies.js`, `frontend/src/redux/api/genre.js`, and `frontend/src/redux/api/users.js`.

#### User-facing movie flows
Movie discovery, listing, cards, details, and related viewing UI are organized under `frontend/src/pages/Movies/AllMovies.jsx`, `frontend/src/pages/Movies/MovieDetails.jsx`, and `frontend/src/pages/Movies/MovieTabs.jsx`. These views fetch movie/genre/user data through the Redux API layer rather than directly owning backend logic.

#### Identity and administration boundaries
Authentication screens and client-side protected navigation reside in `frontend/src/pages/Auth/Login.jsx`, `frontend/src/pages/Auth/Register.jsx`, and `frontend/src/pages/Auth/PrivateRoute.jsx`. Administrative workflows—movie creation/editing, genre management, comment review, and dashboard presentation—are separated under `frontend/src/pages/Admin/CreateMovie.jsx`, `frontend/src/pages/Admin/UpdateMovie.jsx`, and `frontend/src/pages/Admin/Dashboard/AdminDashboard.jsx`. Client guards complement, but do not replace, backend token middleware.

#### Runtime and delivery shape
The frontend is a Vite React application (`frontend/vite.config.js`, `frontend/package.json`) styled with Tailwind configuration (`frontend/tailwind.config.js`). The backend is Node.js/Express with environment-driven settings in `.env`; it connects to MongoDB and exposes the API consumed by the independently built frontend.
