# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

NexHome — a modern American-style second-hand house sales website built with FastAPI + Jinja2 templates. Features user authentication, property listings with search/filter, property CRUD with image upload, favorites, contact info with international phone formatting, and a user dashboard.

## Running the App

```bash
source .venv/bin/activate

# Recreate DB tables (first time or after model changes)
python -c "from database import engine; from models import Base; Base.metadata.drop_all(bind=engine); Base.metadata.create_all(bind=engine)"

# Start the dev server
uvicorn main:app --reload
```

**Prerequisites:**
- Python 3.14
- MySQL server running locally with a `NexHome` database
- Set the `SECRET_KEY` environment variable (used by `auth.py` for JWT signing)

## Architecture

**`main.py`** — FastAPI entry point. Creates the app, includes auth and properties routers, creates DB tables on startup, serves the homepage.

**`auth.py`** — Authentication router (`/auth` prefix). User registration, login (JWT in HttpOnly cookie), logout. `get_current_user()` checks cookie first, then bearer token, returns `None` for anonymous users.

**`config.py`** — Shared config: `SECRET_KEY`, `templates`, `bcrypt_context`, `oauth2_bearer`. Jinja2 cache disabled for Python 3.14 compatibility.

**`database.py`** — SQLAlchemy setup with MySQL engine, `SessionLocal`, `Base`.

**`models.py`** — ORM models: `User` (with email/full_name/phone), `Property` (with contact_email/contact_phone), `PropertyImage`, `Favorite`.

**`properties.py`** — Property CRUD, search/filter, favorites, dashboard. Static paths (`/properties/new`) must be defined before parameterized paths (`/properties/{prop_id}`).

## Data Flow

Request → Router → dependency injection (`get_current_user`, `get_db`) → SQLAlchemy → Jinja2 template → HTML response.

**TemplateResponse API:** `templates.TemplateResponse(request, "template.html", {"user": user, ...})` — request is first arg (Starlette 1.x).

## Key Conventions

- DB sessions: `Annotated[Session, Depends(get_db)]` (the `db_dependency` alias).
- Redirect after POST: `RedirectResponse(url="...", status_code=303)`.
- Image uploads: saved to `static/properties/` with UUID filenames, max 5MB.
- USD currency: prices stored as integer dollars, displayed as `${:,}`.
- Phone input: `templates/components/phone_input.html` — JS-powered country code selector with flags, dynamic placeholders, auto-formatting.
- Route ordering: static paths before parameterized paths in `properties.py`.

## Template Structure

- `templates/base.html` — Tailwind CSS CDN layout with navbar + footer
- `templates/components/` — navbar, footer, property_card macro, phone_input
- `templates/auth/` — login, register
- `templates/properties/` — list, detail, create, edit
- `templates/dashboard/` — user dashboard (my listings + favorites)

## Known Issues

- `database.py` exports the engine as `engin` (typo).
- No `requirements.txt` or `pyproject.toml`.
- Database credentials hardcoded in `database.py`.
