Replace .drone.yml with .woodpecker/ pipeline configs (frontend.yml, api.yml). Convert Drone env vars to Woodpecker equivalents (CI_PIPELINE_NUMBER, CI_COMMIT_SHA), use woodpeckerci/plugin-git for clone with retry, woodpeckerci/plugin-slack for notifications, and plugins/docker for image builds. Update all docs and skills.

# Realestate Crawler
|
|
|
|
## Project Overview
|
|
|
|
A real estate listing aggregation platform that scrapes Rightmove UK listings, extracts square meter data from floorplan images via OCR, calculates transit routes, and serves an interactive map-based web UI.
|
|
|
|
## Command Execution
|
|
|
|
**All commands run inside Docker containers.** The dev environment uses Docker Compose — start it first, then exec into containers for any operations.
|
|
|
|
- **Infrastructure commands** (docker compose, kubectl) — Run locally on the Mac
|
|
- **All project commands** (pytest, poetry, alembic, python, mypy, ruff, etc.) — Run inside the `app` container via `docker compose exec app <command>`
|
|
|
|
See `.claude/skills/` for detailed skills on dev environment, building, and deploying.
|
|
|
|
## Quick Reference
|
|
|
|
| Action | Command |
|
|
|--------|---------|
|
|
| Start all services | `./start.sh` |
|
|
| Rebuild & start | `./start.sh --build` |
|
|
| Stop services | `./start.sh --down` |
|
|
| Run tests | `pytest tests/ -v --cov=. --cov-report=term-missing` |
|
|
| Type check | `mypy .` |
|
|
| Format code | `yapf --style .style.yapf --recursive .` |
|
|
| Lint (CI runs Ruff) | `ruff check .` |
|
|
| DB migration | `alembic upgrade head` |
|
|
| New migration | `alembic revision -m "description"` |
|
|
| Frontend dev | `cd frontend && ./start.sh` |
|
|
|
|
## Tech Stack
|
|
|
|
- **Backend:** Python 3.13, FastAPI, SQLModel (SQLAlchemy 2), Celery + Redis, pytesseract/OpenCV
|
|
- **Frontend:** React 19, TypeScript, Vite, Tailwind CSS, Radix UI, Mapbox GL
|
|
- **Database:** MySQL 9 (prod) / SQLite (local dev), Alembic migrations
|
|
- **Infrastructure:** Docker Compose (dev), Kubernetes (prod), Woodpecker CI
|
|
|
|
## Code Conventions
|
|
|
|
- **Type checking:** Strict mypy (`disallow_untyped_defs=true`). All functions need type annotations.
|
|
- **Formatting:** YAPF (`.style.yapf` config) + Ruff linter (CI on PRs).
|
|
- **Async:** Scraper layer uses `async/await` throughout with `aiohttp`.
|
|
- **Models:** SQLModel for DB entities, Pydantic for request/response validation.
|
|
- **Service layer:** `services/` contains unified handlers used by both CLI and API — add new business logic here, not in API routes or CLI commands directly.
|
|
- **Repository pattern:** `repositories/` for database queries. Don't put raw SQL in services or API.
|
|
- **Tests:** pytest with `pytest-asyncio` (auto mode). Unit tests in `tests/unit/`, integration in `tests/integration/`.
|
|
|
|
## Architecture Layers
|
|
|
|
```
|
|
API (api/app.py) ←→ Services (services/) ←→ Repositories (repositories/)
|
|
↑ ↑ ↑
|
|
Auth (OIDC) Core Logic (rec/) SQLModel (models/)
|
|
↑
|
|
Celery Tasks (tasks/)
|
|
```
|
|
|
|
- `rec/` — Core scraping, OCR, routing logic. Contains circuit breaker and throttle detection.
|
|
- `services/` — Orchestration. Query splitting, listing fetching, caching.
|
|
- `api/` — FastAPI routes, auth middleware, metrics.
|
|
- `models/` — `RentListing`, `BuyListing` SQLModel entities.
|
|
- `tasks/` — Celery background tasks with Redis broker.
|
|
- `config/` — Env-var-based configuration (scraper settings, schedules).
|
|
|
|
## Key Design Decisions
|
|
|
|
- **Query splitting** works around Rightmove's ~1500-result API cap by adaptively splitting queries by district, bedrooms, and price bands (binary search). See `services/query_splitter.py`.
|
|
- **Circuit breaker** (`rec/circuit_breaker.py`) and **throttle detection** (`rec/throttle_detector.py`) protect against rate limiting.
|
|
- **Streaming API** uses NDJSON for progressive loading of large result sets.
|
|
- **Redis** serves dual duty as Celery broker and GeoJSON cache.
|
|
|
|
## Environment Variables
|
|
|
|
See `.env.sample` for the full list. Key ones:
|
|
|
|
- `DB_CONNECTION_STRING` — Database URL
|
|
- `CELERY_BROKER_URL` / `CELERY_RESULT_BACKEND` — Redis URLs
|
|
- `ROUTING_API_KEY` — Google Maps API key
|
|
- `RIGHTMOVE_*` — Scraper tuning (concurrency, delays, thresholds, proxy)
|
|
- `SCRAPE_SCHEDULES` — JSON array of periodic scrape configs
|
|
|
|
## Git Workflow
|
|
|
|
- CI: Woodpecker CI (`.woodpecker/`) builds Docker images on push to `master`, deploys to K8s.
|
|
- Linting: GitHub Actions runs Ruff on PR diffs.
|
|
- Keep commits focused — one logical change per commit.
|
|
- Group related files (e.g., code + its tests) in the same commit.
|
|
|
|
## Directories to Ignore
|
|
|
|
- `node_modules/`, `__pycache__/`, `.idea/`, `data/`, `venv/`, `_cache/`
