Quick start

from modular_api_postgres import DbClient, DbCommand, DbCommandKind, DbConnectionSettings

settings = DbConnectionSettings.from_environment()

client = DbClient(
    settings=settings,
    session_provider=my_session_provider,
    command_executor=my_command_executor,
    transaction_runner=my_transaction_runner,
)

result = client.scalar(
    DbCommand(
        kind=DbCommandKind.SCALAR,
        text="select count(*) from users",
        label="users.count",
    )
)

if result.is_success:
    print(result.value.value)
else:
    print(result.failure.message)

See example/example.py for a complete in-memory wiring sample.

Current slice

• normalized Postgres connection defaults and redacted summaries
• engine-agnostic DbClient, DbRepository, and transaction contracts
• explicit lease ownership semantics for package-owned and application-owned sessions
• health contributor and GraphQL support bundle for higher-level integrations
• real driver bindings intentionally remain outside this first slice
