sonnet-server

The web layer for Petrarca Labs backend services. A FastAPI application factory, an extension mechanism for composing subsystems, and the infrastructure that sits behind a request: database wiring, messaging, caching, guards and readiness.

Version 0.6.0. It is a library, not a running service -- the consuming application owns its entry point and its factory call (ADR-0001).

What it provides

  • Application factory -- create_app wires logging, DI, profiles, extension lifecycle, exception handlers, CORS and the system endpoints (/ping, /version, /health-check), and returns the app plus a startup check coroutine.
  • Extensions -- opt-in subsystem lifecycle with routers, middleware and checks contributed per capability. Extensions may live in other packages.
  • Routing and guards -- router factories that apply preconditions (authenticated caller, tenant context, per-request session) before a handler runs, with the implementations filled by protocol slots.
  • List endpoints -- one pagination envelope with sorting, search and declared client filters.
  • Messaging -- a content-based router over in-process, PostgreSQL LISTEN/NOTIFY, NATS and RabbitMQ channels, with a CloudEvents envelope and request/reply.
  • Caching -- a managed cache with local, distributed and near-cache modes and cross-process invalidation.
  • Readiness stages -- concrete database, messaging and cache checks on the sonnet-core engine.
  • Settings and profiles -- a Settings base you subclass with your own env prefix, and per-deployment subsystem toggles.

Command-line building blocks are not here. They live in sonnet-cli; this package depends on neither typer nor rich. The data layer -- repositories, sessions, filtering, the readiness engine -- lives in sonnet-core, which comes with this package.

Install

uv add "sonnet-server[postgres]"
Extra Adds Use when
postgres psycopg Always, in practice -- PostgreSQL is the target database.
filtering lark Accepting client filter expressions.
graphql strawberry-graphql Serving GraphQL.
nats nats-py Using NATS as the message broker.
rabbitmq aio-pika Using RabbitMQ as the message broker.
redis redis Using a distributed or near cache.
all all of the above Development, or a service that uses most of it.

Usage

Register the extensions the service needs and hand them to the factory. The factory drives them in registration order and does not know what any of them are.

from sonnet_server.app import create_app
from sonnet_server.database.extension import DatabaseExtension
from sonnet_server.extensions import create_extension_registry

_registry = create_extension_registry(
    DatabaseExtension(),
    RestExtension(),
)

app, perform_startup_checks = create_app(
    extension_registry=_registry,
    register_services=register_all_services,
    title="My Server",
    server_name="my_server",
)

Infrastructure extensions go first. See the usage guides for settings, routing, list endpoints, messaging, caching and GraphQL.
