# DealerTower Python Framework (dtpyfw)

**DealerTower Framework** provides reusable, production‑ready building blocks for DealerTower microservices. It’s organized into modular sub‑packages, each focusing on a specific domain:

---

* **Core** – Fundamental utilities
* **API** – FastAPI helpers
* **Database** – SQLAlchemy orchestration
* **Bucket** – S3-compatible storage
* **FTP** – FTP/SFTP file operations
* **Redis** – Caching & Streams
* **Kafka** – Kafka messaging utilities
* **Worker** – Celery task management
* **Encryption** – Hashing & JWT

---

## 📦 Sub‑Package Summaries

### Core

Fundamental utilities and patterns shared across services:

* **Env Management**: `.env` loading + whitelist.
* **Error Handling**: `RequestException` + `exception_to_dict`.
* **Async Bridge**: `async_to_sync` helper.
* **Data Utilities**: list chunking, slug/URL helpers, safe accessors.
* **Request Wrapper**: HTTP calls with telemetry.
* **Retry Decorators**: sync/async retries with backoff.

More details → [Core Docs](docs/core.md)

---

### API

Turnkey FastAPI setup:

* **MainApp** & **SubApp**: compose multi‑app services with CORS, docs, and lifecycle hooks.
* **Middleware**: structured error, validation, and runtime logging.
* **Routing**: `Route` & `Router` classes for declarative endpoint definitions.
* **Auth Helpers**: API key header/query validation.
* **Response Utils**: consistent JSON envelopes with cache headers.

More details → [API Docs](docs/api.md)

---

### Database (DB)

SQLAlchemy orchestration for sync/async workflows:

* **DatabaseConfig**: fluent connection settings.
* **DatabaseInstance**: engine creation, session context managers, health checks.
* **ModelBase**: UUID PKs, timestamps, `.to_dict()`, diffing.
* **Search Helpers**: dynamic filter UI values, min/max aggregations.

More details → [DB Docs](docs/db.md)

---

### Bucket

Simplified S3-compatible storage:

* **Initialization**: custom endpoints or AWS S3 mode.
* **URL Generation**: public object URLs.
* **File Ops**: upload (bytes/path), download, duplicate, safe‑duplicate, delete.
* **Existence Check**: head\_object wrapper.

More details → [Bucket Docs](docs/bucket.md)

---

### FTP/SFTP

Unified FTP & SFTP client:

* **Connection**: auto‑choose ftplib vs Paramiko.
* **Directory Ops**: list, create, remove.
* **File Transfers**: upload/download to path or file‑like object.
* **Metadata**: fetch last‑modified timestamps.

More details → [FTP Docs](docs/ftp.md)

---

### Redis & Streams

Robust caching and message streaming:

* **RedisConfig** + **RedisInstance**: sync/async clients with SSL support.
* **Cache Decorator**: `cache_function` with namespace, TTL, conditional caching.
* **Consumer**: Redis Streams consumer with retry logic, handler registration, and cleanup.
* **Health Check**: simple ping utility.

More details → [Redis Docs](docs/redis.md)

---

### Kafka

Producer & Consumer wrappers for Kafka messaging:

* **KafkaConfig**: builder for connection settings (URL support, SASL, client ID).
* **KafkaInstance**: factory for `KafkaProducer`/`KafkaConsumer` with JSON serialization and context managers.
* **Producer**: send JSON-encoded messages with retries and acks.
* **Consumer**: register per-topic handlers, manual commit support, and polling logic.

More details → [Kafka Docs](docs/kafka.md)

---

### Worker

Celery setup helper for tasks and periodic jobs:

* **Task**: register task routes and RedBeat schedules.
* **Worker**: fluent Celery app builder—broker/backend config, serializers, timezone, and SSL.
* **Auto Discovery**: plug in task list and beat schedule automatically.

More details → [Worker Docs](docs/worker.md)

---

### Encryption

Out‑of‑the-box password & token security:

* **Hash**: bcrypt via Passlib.
* **JWT**: `jwt_encrypt` & `jwt_decrypt` with subject validation and exp check.

More details → [Encryption Docs](docs/encrypt.md)
