## Overview

1. **What this repo is**
   - A Django REST Framework backend for the **Dhaka Threads** e-commerce platform.
   - It exposes a JSON API to a separate frontend client; this repo is not the UI itself.

2. **Top-level runtime boundary**
   - `manage.py` is the Django command entry point.
   - `cloth_store/` is the project configuration package: `settings.py`, `urls.py`, `asgi.py`, and `wsgi.py`.
   - `cloth_store/urls.py` is the central request router that likely mounts the API app and the Django admin.

3. **Main application boundary**
   - The functional backend lives in the single Django app `store/`.
   - That app contains the domain model, API views, serializers, URL routes, admin integration, and migrations.
   - This is the main place to diagram business logic and persistence.

4. **Domain/data layer**
   - `store/models.py` defines the e-commerce entities and relationships.
   - The migration history shows evolving models for things like **orders**, **wishlists**, and **order status**, indicating a relational schema managed through Django ORM.
   - Data is stored in a relational database, with support for PostgreSQL or SQLite per the README.

5. **API/service layer**
   - `store/api_views.py` is the request-handling layer for the REST API.
   - `store/serializers.py` converts ORM objects to/from JSON and is the main validation/shape boundary between HTTP payloads and database records.
   - `store/urls.py` maps API endpoints to those views.

6. **Authentication and user-scoped resources**
   - The backend uses **JWT authentication** via `djangorestframework-simplejwt`.
   - Protected flows include login/refresh/logout and user-specific resources such as cart, wishlist, reviews, and profile updates.
   - The key architectural boundary here is that many endpoints are scoped to the authenticated user and should not expose other users’ data.

7. **E-commerce feature partitioning**
   - The API is organized around product catalog management, cart/wishlist operations, review/rating actions, and user profile handling.
   - Product data is read/write through the API; user-owned collections like cart and wishlist are persisted server-side.
   - Reviews are tied to authenticated users and products, which makes product detail data a combined read path from multiple domain tables.

8. **Admin and operational back office**
   - `store/admin.py` integrates models with the Django admin for manual management.
   - This gives the project a second interface to the same database, separate from the public API.

9. **Infrastructure and deployment**
   - Dependencies show the backend is production-ready with **Gunicorn** and **Whitenoise** for serving Django in deployment.
   - `python-decouple` indicates environment-driven configuration, and `psycopg2-binary` supports PostgreSQL.
   - The README says deployment is on **Render**; `vercel.json` and `build_files.sh` are present as deployment/build artifacts, but the core runtime is the Django API service.

10. **Static/media handling**
   - `static/` exists for collected/static assets; `Pillow` in dependencies suggests image handling for products or related media.
   - There is no large frontend codebase here; static files are infrastructure support, not the primary application surface.

11. **End-to-end data flow**
   - Frontend client sends HTTP requests with JWTs.
   - Django routes the request to `store/api_views.py`.
   - Views query/update Django ORM models, using serializers for validation and JSON formatting.
   - Responses go back to the client; writes are persisted in the database and enforced through auth and model relationships.

12. **Useful diagram framing**
   - Draw this as a three-tier backend: **HTTP/API layer** → **DRF view/serializer layer** → **ORM/database layer**.
   - Surround it with two important external boundaries: **JWT auth** and the **separate frontend client** that consumes the API.
