# python-repositories
|
|
|
|
Unified repository interfaces and technology-specific adapters for Python projects.
|
|
|
|
Subclass an adapter in your own repository to add domain-specific methods while reusing connection management and CRUD operations.
|
|
|
|
## Architecture
|
|
|
|
| Layer | Responsibility |
|
|
| ---------------- | ----------------------------------------------------------------- |
|
|
| **Interfaces** | Abstract contracts for connection, context, and CRUD |
|
|
| **Adapters** | Technology-specific base classes (`RedisAdapter`, `MinioAdapter`) |
|
|
| **Your project** | Subclass an adapter and add domain methods |
|
|
|
|
## Optional dependencies
|
|
|
|
Install with the extras you need:
|
|
|
|
```bash
|
|
uv add python-repositories[redis]
|
|
uv add python-repositories[minio]
|
|
uv add python-repositories[redis,minio]
|
|
```
|
|
|
|
### Redis (`JsonRepositoryInterface`)
|
|
|
|
Requires Redis with the RedisJSON module (e.g. redis-stack).
|
|
|
|
| Environment variable | Description |
|
|
| -------------------- | ---------------------------------------------------- |
|
|
| `REDIS_URI` | Redis connection URL (e.g. `redis://localhost:6379`) |
|
|
|
|
### MinIO (`ObjectRepositoryInterface`)
|
|
|
|
| Environment variable | Description |
|
|
| -------------------- | ------------------------------------------- |
|
|
| `MINIO_ENDPOINT` | MinIO server endpoint |
|
|
| `MINIO_ACCESS_KEY` | Access key |
|
|
| `MINIO_SECRET_KEY` | Secret key |
|
|
| `MINIO_BUCKET` | Bucket name (created on connect if missing) |
|
|
|
|
## Quick start
|
|
|
|
### JSON documents with Redis
|
|
|
|
```python
|
|
from python_repositories.examples.user_json_repository import UserJsonRepository
|
|
|
|
with UserJsonRepository() as repo:
|
|
repo.save_user("alice", {"name": "Alice", "email": "alice@example.com"})
|
|
user = repo.get_user("alice")
|
|
repo.delete_user("alice")
|
|
```
|
|
|
|
### Binary objects with MinIO
|
|
|
|
```python
|
|
from io import BytesIO
|
|
|
|
from python_repositories.examples.artifact_object_repository import (
|
|
ArtifactObjectRepository,
|
|
)
|
|
|
|
with ArtifactObjectRepository() as repo:
|
|
repo.store_artifact("report-1", BytesIO(b"pdf bytes here"))
|
|
data = repo.get_artifact("report-1")
|
|
```
|
|
|
|
### Subclassing in your own project
|
|
|
|
```python
|
|
from python_repositories import RedisAdapter
|
|
|
|
class UserRepository(RedisAdapter):
|
|
def _key(self, user_id: str) -> str:
|
|
return f"user:{user_id}"
|
|
|
|
def get_user(self, user_id: str) -> dict | None:
|
|
return self.get(self._key(user_id))
|
|
|
|
def save_user(self, user_id: str, user: dict) -> None:
|
|
self.set(self._key(user_id), user)
|
|
```
|
|
|
|
## Public API
|
|
|
|
```python
|
|
from python_repositories import (
|
|
ConnectionAwareInterface,
|
|
ContextAwareInterface,
|
|
JsonRepositoryInterface,
|
|
ObjectRepositoryInterface,
|
|
RedisAdapter,
|
|
MinioAdapter,
|
|
)
|
|
```
|
|
|
|
## Development
|
|
|
|
```bash
|
|
uv sync --all-extras
|
|
uv run pre-commit install # once per clone — runs hooks on git commit
|
|
uv run pytest tests/integration/ -v
|
|
```
|
|
|
|
`pre-commit` is included in the dev dependency group. `uv sync` installs the CLI, but git does not run hooks until you install them with `pre-commit install` (one time per clone). After that, commits run the checks defined in [`.pre-commit-config.yaml`](.pre-commit-config.yaml) (ruff, mypy, pyupgrade, prettier, and general file hygiene).
|
|
|
|
To run all hooks manually without committing:
|
|
|
|
```bash
|
|
uv run pre-commit run --all-files
|
|
```
|
|
|
|
Integration tests require Docker (testcontainers).
