csrd-repository
Base repository and database adapter abstractions for FastAPI microservices.
Package: csrd.repository · Import: from csrd.repository import BaseRepository, SQLiteAdapter
What's included
BaseRepository— abstract repository with model parsing (requires an adapter)ABCDatabaseAdapter/DBProtocol— async database adapter abstraction with lifecycle and explicit transactionsSQLiteAdapter— async SQLite implementation via aiosqlite (persistent connection, atomic upsert)ExecuteResult— immutable snapshot of query metadata (replaces raw cursor return)- Optional
sqlalchemyintegration for query building (pip install csrd-repository[sql])
Installation
uv pip install "csrd-repository @ git+ssh://git@github.com/csrd-api/fastapi-common.git#subdirectory=packages/repository"
Dependencies
csrd-models(Tier 2)
Transactions
All adapters expose an explicit unit-of-work context:
async with adapter.transaction() as tx:
users = user_repository.with_adapter(tx)
credentials = credential_repository.with_adapter(tx)
user = await users.insert("users", user_values)
await credentials.insert("credentials", {"user_id": user["id"], **credential_values})
The yielded adapter uses one physical connection. Normal exit commits;
exceptions and cancellation roll back. Nested transaction() calls are
rejected with RuntimeError, and a transaction-bound adapter raises
RuntimeError if reused after context exit.
Locking remains database-specific: PostgreSQL and MariaDB support their native
row-lock syntax (for example SELECT ... FOR UPDATE); SQLite serializes
operations on its single connection and does not support FOR UPDATE.
