    FastAPI OpenAPI First \u2014 strict OpenAPI-first application bootstrap for FastAPI.

    FastAPI OpenAPI First is a contract-first infrastructure library that enforces OpenAPI as the single source of truth for FastAPI services.

    OpenAPI-first application bootstrap for FastAPI.

    This module provides OpenAPIFirstApp, a thin but strict abstraction that enforces OpenAPI as the single source of truth for a FastAPI service.

    Notes

    Core Principles:

    - The OpenAPI specification (JSON or YAML) defines the entire API surface.\n- Every `operationId` in the OpenAPI spec must have a corresponding\n  Python handler function.\n- Handlers are plain Python callables (no FastAPI decorators).\n- FastAPI route registration is derived exclusively from the spec.\n- FastAPI's autogenerated OpenAPI schema is fully overridden.\n

    Responsibilities:

    - Loads and validates an OpenAPI 3.x specification.\n- Dynamically binds HTTP routes to handler functions using `operationId`.\n- Registers routes with FastAPI at application startup.\n- Ensures runtime behavior matches the OpenAPI contract exactly.\n

    Constraints:

    - This module intentionally does NOT:\n    - Generate OpenAPI specs.\n    - Generate client code.\n    - Introduce a new framework or lifecycle.\n    - Alter FastAPI dependency injection semantics.\n

    Bases: FastAPI

    FastAPI application enforcing OpenAPI-first design.

    Notes

    Responsibilities:

    - `OpenAPIFirstApp` subclasses `FastAPI` and replaces manual route\n  registration with OpenAPI-driven binding.\n- All routes are derived from the provided OpenAPI specification,\n  and each ``operationId`` is mapped to a Python function in the\n  supplied routes module.\n- Auth dependencies are auto-injected from the spec's\n  ``securitySchemes`` and per-operation ``security`` fields.\n

    Guarantees:

    - No route can exist without an OpenAPI declaration.\n- No OpenAPI operation can exist without a handler.\n- Swagger UI and ``/openapi.json`` always reflect the provided spec.\n- Handler functions remain framework-agnostic and testable.\n- Auth enforcement is driven entirely by the spec \u2014 no manual\n  middleware or decorators required.\n
    Example

    Initialize the application.

    Parameters:

    Name Type Description Default openapi_path str

    Filesystem path to the OpenAPI 3.x specification file. This specification is treated as the authoritative API contract.

    Notes

    Core Responsibility:

    FastAPI OpenAPI First \u2014 strict OpenAPI-first application bootstrap for FastAPI.

    FastAPI OpenAPI First is a contract-first infrastructure library that enforces OpenAPI as the single source of truth for FastAPI services.

    The library removes decorator-driven routing and replaces it with deterministic, spec-driven application assembly. Every HTTP route, method, and operation is defined in OpenAPI first and bound to Python handlers explicitly via operationId.

    OpenAPI-first application bootstrap for FastAPI.

    This module provides OpenAPIFirstApp, a thin but strict abstraction that enforces OpenAPI as the single source of truth for a FastAPI service.

    Notes

    Core Principles:

    - The OpenAPI specification (JSON or YAML) defines the entire API surface.\n- Every `operationId` in the OpenAPI spec must have a corresponding\n  Python handler function.\n- Handlers are plain Python callables (no FastAPI decorators).\n- FastAPI route registration is derived exclusively from the spec.\n- FastAPI's autogenerated OpenAPI schema is fully overridden.\n

    Responsibilities:

    - Loads and validates an OpenAPI 3.x specification.\n- Dynamically binds HTTP routes to handler functions using `operationId`.\n- Registers routes with FastAPI at application startup.\n- Ensures runtime behavior matches the OpenAPI contract exactly.\n

    Constraints:

    - This module intentionally does NOT:\n    - Generate OpenAPI specs.\n    - Generate client code.\n    - Introduce a new framework or lifecycle.\n    - Alter FastAPI dependency injection semantics.\n

    FastAPI application enforcing OpenAPI-first design.

    Notes

    Responsibilities:

    - `OpenAPIFirstApp` subclasses `FastAPI` and replaces manual route\n  registration with OpenAPI-driven binding.\n- All routes are derived from the provided OpenAPI specification,\n  and each ``operationId`` is mapped to a Python function in the\n  supplied routes module.\n- Auth dependencies are auto-injected from the spec's\n  ``securitySchemes`` and per-operation ``security`` fields.\n

    Guarantees:

    - No route can exist without an OpenAPI declaration.\n- No OpenAPI operation can exist without a handler.\n- Swagger UI and ``/openapi.json`` always reflect the provided spec.\n- Handler functions remain framework-agnostic and testable.\n- Auth enforcement is driven entirely by the spec \u2014 no manual\n  middleware or decorators required.\n
    Example
    from openapi_first import OpenAPIFirstApp\nimport app.routes as routes\n\napp = OpenAPIFirstApp(\n    openapi_path=\"app/openapi.json\",\n    routes_module=routes,\n    title=\"Example Service\",\n)\n

    Application entry point for an OpenAPI-first CRUD example service.

    This module constructs a FastAPI application exclusively from an OpenAPI specification and a handler namespace, without using decorator-driven routing.

    All HTTP routes, methods, request/response schemas, and operation bindings are defined in the OpenAPI document referenced by openapi_path. Python callables defined in the routes module are bound to OpenAPI operations strictly via operationId.

    This module contains no routing logic, persistence concerns, or framework configuration beyond application assembly.

    FastAPI OpenAPI First \u2014 strict OpenAPI-first application bootstrap for FastAPI.

    FastAPI OpenAPI First is a contract-first infrastructure library that enforces OpenAPI as the single source of truth for FastAPI services.

    The library removes decorator-driven routing and replaces it with deterministic, spec-driven application assembly. Every HTTP route, method, and operation is defined in OpenAPI first and bound to Python handlers explicitly via operationId.

    OpenAPI-first application bootstrap for FastAPI.

    This module provides OpenAPIFirstApp, a thin but strict abstraction that enforces OpenAPI as the single source of truth for a FastAPI service.

    Notes

    Core Principles:

    - The OpenAPI specification (JSON or YAML) defines the entire API surface.\n- Every `operationId` in the OpenAPI spec must have a corresponding\n  Python handler function.\n- Handlers are plain Python callables (no FastAPI decorators).\n- FastAPI route registration is derived exclusively from the spec.\n- FastAPI's autogenerated OpenAPI schema is fully overridden.\n

    Responsibilities:

    - Loads and validates an OpenAPI 3.x specification.\n- Dynamically binds HTTP routes to handler functions using `operationId`.\n- Registers routes with FastAPI at application startup.\n- Ensures runtime behavior matches the OpenAPI contract exactly.\n

    Constraints:

    - This module intentionally does NOT:\n    - Generate OpenAPI specs.\n    - Generate client code.\n    - Introduce a new framework or lifecycle.\n    - Alter FastAPI dependency injection semantics.\n

    Parameters:

    Name Type Description Default openapi_path str

    Filesystem path to the OpenAPI 3.x specification file. This specification is treated as the authoritative API contract.

    required routes_module ModuleType

    Python module containing handler functions whose names correspond exactly to OpenAPI operationId values.

    {}

    Raises:

    Type Description OpenAPIFirstError

    If the OpenAPI specification is invalid, or if any declared operationId does not have a corresponding handler function.

    Notes

    Responsibilities:

    - `OpenAPIFirstApp` subclasses `FastAPI` and replaces manual route\n  registration with OpenAPI-driven binding.\n- All routes are derived from the provided OpenAPI specification,\n  and each ``operationId`` is mapped to a Python function in the\n  supplied routes module.\n- Auth dependencies are auto-injected from the spec's\n  ``securitySchemes`` and per-operation ``security`` fields.\n

    Guarantees:

    - No route can exist without an OpenAPI declaration.\n- No OpenAPI operation can exist without a handler.\n- Swagger UI and ``/openapi.json`` always reflect the provided spec.\n- Handler functions remain framework-agnostic and testable.\n- Auth enforcement is driven entirely by the spec \u2014 no manual\n  middleware or decorators required.\n

    FastAPI OpenAPI First \u2014 strict OpenAPI-first application bootstrap for FastAPI.

    FastAPI OpenAPI First is a contract-first infrastructure library that enforces OpenAPI as the single source of truth for FastAPI services.

    The library removes decorator-driven routing and replaces it with deterministic, spec-driven application assembly. Every HTTP route, method, and operation is defined in OpenAPI first and bound to Python handlers explicitly via operationId.

    OpenAPI-first application bootstrap for FastAPI.

    This module provides OpenAPIFirstApp, a thin but strict abstraction that enforces OpenAPI as the single source of truth for a FastAPI service.

    Notes

    Core Principles:

    - The OpenAPI specification (JSON or YAML) defines the entire API surface.\n- Every `operationId` in the OpenAPI spec must have a corresponding\n  Python handler function.\n- Handlers are plain Python callables (no FastAPI decorators).\n- FastAPI route registration is derived exclusively from the spec.\n- FastAPI's autogenerated OpenAPI schema is fully overridden.\n

    Responsibilities:

    - Loads and validates an OpenAPI 3.x specification.\n- Dynamically binds HTTP routes to handler functions using `operationId`.\n- Registers routes with FastAPI at application startup.\n- Ensures runtime behavior matches the OpenAPI contract exactly.\n

    Constraints:

    - This module intentionally does NOT:\n    - Generate OpenAPI specs.\n    - Generate client code.\n    - Introduce a new framework or lifecycle.\n    - Alter FastAPI dependency injection semantics.\n

    Notes

    Responsibilities:

    - `OpenAPIFirstApp` subclasses `FastAPI` and replaces manual route\n  registration with OpenAPI-driven binding.\n- All routes are derived from the provided OpenAPI specification,\n  and each ``operationId`` is mapped to a Python function in the\n  supplied routes module.\n- Auth dependencies are auto-injected from the spec's\n  ``securitySchemes`` and per-operation ``security`` fields.\n

    Guarantees:

    - No route can exist without an OpenAPI declaration.\n- No OpenAPI operation can exist without a handler.\n- Swagger UI and ``/openapi.json`` always reflect the provided spec.\n- Handler functions remain framework-agnostic and testable.\n- Auth enforcement is driven entirely by the spec \u2014 no manual\n  middleware or decorators required.\n

    Application entry point for an OpenAPI-first CRUD example service.

    This module constructs a FastAPI application exclusively from an OpenAPI specification and a handler namespace, without using decorator-driven routing.

    All HTTP routes, methods, request/response schemas, and operation bindings are defined in the OpenAPI document referenced by openapi_path. Python callables defined in the routes module are bound to OpenAPI operations strictly via operationId.

    This module contains no routing logic, persistence concerns, or framework configuration beyond application assembly.

    Design guarantees: - OpenAPI is the single source of truth - No undocumented routes can exist - Every OpenAPI operationId must resolve to exactly one handler - All contract violations fail at application startup

    Overview — The OpenAPI-First Mental Model

    +

    openapi-first inverts the usual FastAPI workflow. Instead of decorating routes in code and letting FastAPI invent an OpenAPI document for you, you write one OpenAPI document first and let the library assemble both the application and the client from it. The spec is the contract; code is the implementation.

    +
    +

    🧠 1. The Mental Model

    +

    1.1 One source of truth

    +

    Your OpenAPI document (openapi.yaml or openapi.json) is the single authoritative contract:

    +
     1
    + 2
    + 3
    + 4
    + 5
    + 6
    + 7
    + 8
    + 9
    +10
    +11
    paths:
    +  /health:
    +    get:
    +      operationId: get_health
    +      responses:
    +        "200":
    +          description: OK
    +          content:
    +            application/json:
    +              schema:
    +                type: object
    +
    +

    Every route, method, parameter, schema, and security requirement lives here — and only here. Code never declares routes.

    +

    1.2 operationId is the binding key

    +

    The only bridge between the spec and your Python code is the operationId. Each operation maps, by name, to exactly one plain callable:

    +
    1
    +2
    +3
    +4
    # routes.py
    +def get_health():
    +    """Health check operation handler."""
    +    return {"status": "ok"}
    +
    +

    openapi_first resolves operationId: get_healthroutes.get_health and registers the route. No decorators, no @app.get, no routing metadata in code.

    +

    Guarantees this binding provides:

    +
      +
    • 🚫 No undocumented route can exist — every route must be in the spec
    • +
    • 🚫 No spec operation can go unhandled — every operationId must resolve at startup
    • +
    • 🔒 No auth can be bypassed — security is injected from securitySchemes + per-operation security, spec-driven
    • +
    • 🧱 No drift possible — the server and client are built from the same document
    • +
    +

    1.3 Fail-fast by design

    +

    Contract violations are detected at application startup (or client construction), never silently at request time:

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    What goes wrongWhen it fails
    Invalid / unloadable specload_openapi at startup
    Spec fails OpenAPI 3.x validationload_openapi at startup
    operationId missing a handlerbind_routes at startup
    Operation declared but no operationIdbind_routes at startup
    Missing / duplicate operationId in clientOpenAPIClient(...) construction
    +
    +

    ⚙️ 2. What It Looks Like

    +

    2.1 Scaffold an application

    +
    1
    +2
    openapi-first scaffold health_app my-health-service
    +openapi-first scaffold --list
    +
    +

    scaffold copies a bundled template (verbatim — no code generation, no mutation) into a directory of your choice.

    +

    2.2 Bootstrap the server

    +
    1
    +2
    +3
    +4
    +5
    +6
    +7
    +8
    +9
    # main.py
    +from openapi_first.app import OpenAPIFirstApp
    +import routes
    +
    +app = OpenAPIFirstApp(
    +    openapi_path="openapi.yaml",
    +    routes_module=routes,
    +    title="My Service",
    +)
    +
    +

    Run with your FastAPI-compatible server (ASGI):

    +
    uvicorn main:app --reload
    +
    +

    FastAPI itself drives the server; every route, response model, and security dependency comes from the spec. /openapi.json and Swagger UI always reflect the spec, byte-for-byte.

    +

    2.3 Talk to it with the client

    +
     1
    + 2
    + 3
    + 4
    + 5
    + 6
    + 7
    + 8
    + 9
    +10
    # client-side
    +from openapi_first.loader import load_openapi
    +from openapi_first.client import OpenAPIClient
    +
    +spec = load_openapi("openapi.yaml")
    +client = OpenAPIClient(spec)
    +
    +response = client.get_health()          # operationId-driven call
    +print(response.status_code)             # 200
    +print(response.json())                  # {"status": "ok"}
    +
    +

    OpenAPIClient builds one callable per operationId from the same spec, so the client can never drift from the server.

    +
    +

    🧩 3. Where Things Live

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    ConcernModule
    Load + validate specopenapi_first.loader

    Models / routes CLIopenapi_first.cli
    Bundled templatesopenapi_first.templates
    +

    Jurisdictions:

    +
      +
    • loader, app, binder, client, errors, security are the library API surface — stable, tested, documented.
    • +
    • templates are copyable scaffolds — not part of the library API; excluded from lint/format/type gates, never imported at runtime.
    • +
    +
    +

    📄 4. The Non-Goals

    +

    openapi-first deliberately does not:

    +
      +
    • Parse decorators to generate an OpenAPI schema (that's default FastAPI behavior — the inverse)
    • +
    • Generate models from code at runtime (only at build time via CLI, from spec → Pydantic)
    • +
    • Validate request/response bodies against the spec at runtime (contract is enforced at startup / client construction; FastAPI + Pydantic handle runtime coercion)
    • +
    • Invent routing from path conventions — operationId binding only
    • +
    • Ship a production feature set in the bundled templates (they're demos/scaffolds: in-memory stores, no concurrency, no auth configured)
    • +
    +
    +

    Components — What Ships in the Box

    +

    The library is deliberately small. Everything you need to run an OpenAPI-first service and talk to it with a strict client fits in a handful of modules.

    +
    +

    🗂️ 1. Module Map

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    openapi_first.templatesCopyable application templates (NOT library API)openapi-first scaffold
    +
    +

    ⚙️ 2. loader — Load & Validate

    +

    load_openapi(path: str | Path) -> dict[str, Any] (in openapi_first/loader.py).

    +

    loader.py ensures a spec is real, readable, parseable, and schema-valid before anything else runs — a golden rule of fail-fast.

    +
    1
    +2
    +3
    from openapi_first.loader import load_openapi
    +
    +spec = load_openapi("openapi.yaml")
    +
    +

    Behavior:

    +
      +
    • Accepts .json, .yaml, .yml (parsed by extension).
    • +
    • Runs strict OpenAPI 3.x validation (openapi-spec-validator) at load time.
    • +
    • Raises OpenAPISpecLoadError on: missing file, unparseable content, or spec-validation failure.
    • +
    • Does not modify, coerce, or "fix" the spec — it's a read-only gate.
    • +
    +

    Env-var resolution lives at the security layer rather than the loader (see Security).

    +
    +

    🧬 3. app — The Application Bootstrap

    +

    OpenAPIFirstApp (in openapi_first/app.py) is a FastAPI subclass that replaces manual route registration with OpenAPI-driven binding.

    +
    1
    +2
    +3
    +4
    +5
    +6
    +7
    +8
    from openapi_first.app import OpenAPIFirstApp
    +import routes
    +
    +app = OpenAPIFirstApp(
    +    openapi_path="openapi.yaml",
    +    routes_module=routes,
    +    title="My Service",
    +)
    +
    +

    Startup pipeline (fail-fast, in this order):

    +
      +
    1. Load the spec (.yaml/.json).
    2. +
    3. Validate it against OpenAPI 3.x schema.
    4. +
    5. Parse securitySchemes and per-operation security.
    6. +
    7. Build per-route security dependencies.
    8. +
    9. Bind every path/method → handler by operationId; a missing handler, a missing operationId on a declared operation, or an unbound operation raises at startup.
    10. +
    +

    Guarantees:

    +
      +
    • Every route has a spec declaration (no undocumented routes).
    • +
    • Every spec operation has a handler (no unhandled operations).
    • +
    • Auth enforcement is spec-driven, not hand-wired.
    • +
    • /openapi.json + Swagger UI always reflect the provided spec.
    • +
    +

    Keyword arguments beyond openapi_path / routes_module pass straight through to fastapi.FastAPI (it's a subclass — title, version, middleware, lifespan, … all work).

    +
    +

    🔗 4. binder — Spec → Route Binding

    +

    bind_routes(app, spec, routes_module, security_deps=None) -> None (in openapi_first/binder.py).

    +

    This is the heart of the OpenAPI-first guarantee. For each path + HTTP method in the spec:

    +
      +
    1. Reads the operation's operationId.
    2. +
    3. Looks up routes_module.<operationId> — a plain callable.
    4. +
    5. Registers a FastAPI APIRoute bound to that handler, injecting Depends(...) for any matching security requirements.
    6. +
    +

    Failures are explicit and early:

    + + + + + + + + + + + + + + + + + + + + + +
    ConditionRaised
    No operationId on an operationMissingOperationHandler
    operationId has no handler functionMissingOperationHandler
    A path/method declared but unboundMissingOperationHandler
    +

    Handlers stay framework-agnostic: they're plain functions (payload, id, response) named after operationIds — no decorators, no routing metadata.

    +
    +

    📡 5. client — The Other Side of the Contract

    +

    OpenAPIClient(spec, base_url=None, client=None) (in openapi_first/client.py).

    +

    The same spec that builds the server builds its client — one callable per operationId, keyed by name:

    +
    1
    +2
    +3
    +4
    +5
    +6
    +7
    +8
    +9
    from openapi_first.loader import load_openapi
    +from openapi_first.client import OpenAPIClient
    +
    +spec = load_openapi("openapi.yaml")
    +client = OpenAPIClient(spec)
    +
    +response = client.get_health()
    +response = client.get_user(path_params={"user_id": 1})
    +response = client.create_user(body={"name": "Ada"})
    +
    +

    How operations become methods:

    +
      +
    • Each operationId → a dynamically-built callable on the client.
    • +
    • Path parameterspath_params={"user_id": 1}.
    • +
    • Request bodybody={...} (JSON) or raw content for non-JSON media types.
    • +
    • Query/headersquery= / headers=.
    • +
    • Returns the raw httpx.Response (no implicit deserialization, no hidden schema inference).
    • +
    +

    Client-construction guarantees (fail-fast, same philosophy as the app):

    +
      +
    • Spec must declare at least one servers entry (base_url falls back to it).
    • +
    • Spec must have paths.
    • +
    • Every operation must have a unique operationId.
    • +
    • Required params must match the spec at call time.
    • +
    +

    Construction errors raise OpenAPIClientError; request-time errors surface as httpx exceptions with operationId context.

    +
    +

    💥 6. errors — Explicit Error Hierarchy

    +

    Everything raised by openapi-first derives from OpenAPIFirstError (in openapi_first/errors.py), so callers can handle first-party failures with a single except:

    +
      +
    • OpenAPIFirstError — base (comparable / aims to be picklable share).
    • +
    • OpenAPIClientError — client-side contract violations.
    • +
    • MissingOperationHandler — spec declares an operation whose handler is missing or unresolvable; carries path, method, and optional operationId.
    • +
    +

    See Error Handling for the full table.

    +
    +

    🛡️ 7. security — Auth from the Spec

    +

    security.py turns an OpenAPI securitySchemes section into FastAPI Depends(...) objects — no manual middleware.

    +
      +
    • parse_security_schemes(spec) -> dict[str, dict] — collects schemes, resolving {ENV_VAR} placeholders.
    • +
    • make_security_dependencies(spec, security_schemes) -> dict[str, list[Depends]] — builds METHOD:/path → dependency list from per-operation security, falling back to top-level security.
    • +
    +

    Supported scheme types (extensible):

    +
      +
    • type: http, scheme: bearerOpenAPIFirstSecurityDependency(HTTPBearer). With x-introspect-path/x-server-url, it introspects the JWT against an auth service; optionally sets request.state.user. Without introspection, it validates token presence and stores it on request.state.token.
    • +
    • API-key style schemes via the same resolution path.
    • +
    +

    Key properties: resolution is per-operation, env placeholders resolve once at startup, and dependencies are injected by binder — your handlers never mention security.

    +
    +

    🏭 8. codegen & cli — Build-Time Tooling

    +

    Generation is strictly build-time — spec → code, run once by a developer, committed:

    +

    openapi-first models <spec> -o <file>

    +

    Generates Pydantic models from spec schemas (wraps datamodel_code_generator):

    +
    1
    +2
    # cli path
    +openapi-first models openapi.yaml -o app/models.py
    +
    +

    openapi-first routes <spec> -o <dir> [--use-models] [--models-module models]

    +

    Generates one routes_<resource>.py stub file per resource, with NotImplementedError handlers bound to operationIds (optionally importing your generated models):

    +
    openapi-first routes openapi.yaml -o app/routes --use-models
    +
    +

    openapi-first scaffold <template> [path]

    +

    Copies a bundled application template verbatim (see Templates).

    +
    +

    🧱 9. templates — Copyable Applications

    +

    Four bundled, runnable applications live under openapi_first/templates/: health_app, crud_app, model_app, and vet_app. They are not part of the library API — no lint/format/type gates, never imported at runtime. They exist to be copied via:

    +
    1
    +2
    openapi-first scaffold <template> [target-dir]
    +openapi-first scaffold --list

    Use Case 1: Quickstart — Build Your First OpenAPI-First Service

    +

    This guide walks you from an empty directory to a running, contract-driven service in a few minutes, then talks to it with the generated client.

    +
    +

    🛠️ 1. Prerequisites

    +
      +
    • Python 3.10+
    • +
    • openapi-first installed (see Overview)
    • +
    • pip install "fastapi[standard]" (or uvicorn) to run the app
    • +
    +
    +

    📄 2. Write the OpenAPI document

    +

    OpenAPI comes first. Create openapi.yaml:

    +
     1
    + 2
    + 3
    + 4
    + 5
    + 6
    + 7
    + 8
    + 9
    +10
    +11
    +12
    +13
    +14
    +15
    +16
    +17
    +18
    +19
    +20
    +21
    +22
    +23
    +24
    +25
    +26
    openapi: 3.0.3
    +info:
    +  title: Greeting Service
    +  version: 1.0.0
    +servers:
    +  - url: http://localhost:8000
    +paths:
    +  /greet/{name}:
    +    get:
    +      operationId: get_greeting
    +      parameters:
    +        - name: name
    +          in: path
    +          required: true
    +          schema:
    +            type: string
    +      responses:
    +        "200":
    +          description: A greeting
    +          content:
    +            application/json:
    +              schema:
    +                type: object
    +                properties:
    +                  greeting:
    +                    type: string
    +
    +

    Key points: every operation needs operationId, and every route must exist only here.

    +
    +

    🧑‍💻 3. Write the handlers

    +

    Create routes.py — plain functions, no decorators, named exactly like the operationIds:

    +
    1
    +2
    +3
    +4
    # routes.py
    +def get_greeting(name: str) -> dict:
    +    """Return a greeting for the given name."""
    +    return {"greeting": f"Hello, {name}!"}
    +
    +

    If a handler is missing at startup, the app refuses to boot (MissingOperationHandler) — the fail-fast guarantee catches contract drift immediately.

    +
    +

    🚀 4. Bootstrap the app

    +

    Create main.py:

    +
    1
    +2
    +3
    +4
    +5
    +6
    +7
    +8
    +9
    # main.py
    +from openapi_first.app import OpenAPIFirstApp
    +import routes
    +
    +app = OpenAPIFirstApp(
    +    openapi_path="openapi.yaml",
    +    routes_module=routes,
    +    title="Greeting Service",
    +)
    +
    +

    Run it:

    +
    uvicorn main:app --reload
    +
    +

    Visit http://localhost:8000/docs (Swagger UI) and http://localhost:8000/openapi.json — both are generated from your spec.

    +
    +

    📡 5. Call it with the client

    +

    The same spec builds a strict client:

    +
     1
    + 2
    + 3
    + 4
    + 5
    + 6
    + 7
    + 8
    + 9
    +10
    # client.py
    +from openapi_first.loader import load_openapi
    +from openapi_first.client import OpenAPIClient
    +
    +spec = load_openapi("openapi.yaml")
    +client = OpenAPIClient(spec)
    +
    +response = client.get_greeting(path_params={"name": "Ada"})
    +print(response.status_code)   # 200
    +print(response.json())        # {"greeting": "Hello, Ada!"}
    +
    +
    +

    Use Case 2: Templates — Copyable Reference Applications

    +

    openapi-first ships four runnable, copyable applications under openapi_first/templates/. They are not part of the library API — they are bundled scaffold examples you copy into your own project and build on.

    +
    +

    🎬 1. What Templates Are

    +

    A template is a complete, self-contained OpenAPI-first service:

    +
      +
    • A bundled directory inside openapi_first/templates/<name>/
    • +
    • Copyable verbatim — no code generation, no mutation — via the CLI
    • +
    • Each one demonstrates a specific set of OpenAPI-first behaviors and FastAPI features
    • +
    +

    All templates share the same skeleton:

    +
    1
    +2
    +3
    +4
    +5
    +6
    <name>_app/
    +├── __init__.py      # explains the template + how to scaffold it
    +├── openapi.yaml     # the contract (source of truth)
    +├── main.py          # assembles OpenAPIFirstApp from the spec
    +├── routes.py        # operationId-bound handler functions
    +└── data.py          # in-memory data store (demo only)
    +
    +
    +

    📋 2. The Four Templates

    +

    2.1 health_app — minimal liveness probe

    +
    1
    +2
    +3
    openapi-first scaffold health_app
    +# or into a custom directory:
    +openapi-first scaffold health_app my-health-service
    +
    + + + + + + + + + + + + + + + + + + + + + +
    FilePurpose
    openapi.yamlGET /healthoperationId: get_health
    routes.pyget_health() returns {"status": "ok"}
    main.pyOpenAPIFirstApp(openapi_path="openapi.yaml", routes_module=routes)
    +

    Why it exists: the absolute minimal OpenAPI-first round trip — one operation, one handler, zero moving parts. The best starting point to internalize the mental model.

    +

    Smoke test:

    +
    1
    +2
    +3
    +4
    pip install -e .
    +uvicorn main:app
    +curl http://localhost:8000/health
    +# → {"status": "ok"}
    +
    +

    2.2 crud_app — dict-based CRUD

    +
    openapi-first scaffold crud_app my-crud-service
    +
    + + + + + + + + + + + + + + + + + + + + + +
    FilePurpose
    openapi.yamlFull CRUD over /items (list/get/create/update/delete)
    routes.pyHandlers bound via operationIds list_items, get_item, create_item, update_item, delete_item
    data.pyIn-memory dict store with auto-incrementing id
    +

    Behaviors you learn:

    +
      +
    • Explicit status codescreate_item/delete_item take response: Response and set 201/204; get_item/update_item raise HTTPException(404) on KeyError
    • +
    • Handlers as plain callables — no FastAPI decorators, routing comes solely from the spec
    • +
    • Mock data storedata.py is a copyable in-memory store, explicitly not production-ready
    • +
    +

    2.3 model_app — Pydantic model CRUD

    +
    openapi-first scaffold model_app my-model-service
    +
    + + + + + + + + + + + + + + + + + + + + + + + + + +
    FilePurpose
    openapi.yamlSame CRUD surface, schemas reference models
    models.pyPydantic Item, ItemCreate, ItemBase (request/response models)
    routes.pyHandlers type-annotated with the models; create_item sets 201
    data.pyIn-memory store returning real model instances
    +

    Behaviors you learn:

    +
      +
    • Pydantic request/response models — payloads validated and serialized via FastAPI
    • +
    • Same handler contracts — identical operationId set as crud_app, so the two are interchangeable
    • +
    • Models in the client too — the same spec drives OpenAPIClient body handling
    • +
    + +
    openapi-first scaffold vet_app my-vet-clinic
    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    FilePurpose
    openapi.yamlFive resources (parents, vets, treatments, pets, appointments) + SSE + upload + discriminated unions
    models.pyPydantic models incl. discriminated unions (noteType literal fields)
    routes.py~20 handlers across all resources, incl. pagination, filtering, photo upload, SSE streaming
    sse.pyServer-Sent Events helper (StreamingResponse, per-pet subscriber queues, background asyncio workers)
    data.pyLarger in-memory store (parents → vets → treatments → pets → appointments)
    main.pyApp + CORS + lifespan example
    +

    Behaviors you learn — the advanced tier:

    +
      +
    • Discriminated unionsProcedureNotes uses oneOf + discriminator.noteType mapping; Pydantic models use Literal[...] discriminator fields
    • +
    • SSE streaming — a GET /pets/{id}/actions operation streaming text/event-stream via StreamingResponse with background task workers
    • +
    • File uploadUploadFile handler setting a multi-part body
    • +
    • CORS + middlewareadd_middleware(CORSMiddleware, ...) alongside the spec-driven setup
    • +
    • Response injection — handlers set 201/204 explicitly via injected Response
    • +
    +
    +

    🚀 3. CLI Reference

    +
    1
    +2
    +3
    +4
    +5
    +6
    +7
    +8
    # List available templates
    +openapi-first scaffold --list
    +
    +# Copy a template into its default directory (template name, dashes)
    +openapi-first scaffold health_app
    +
    +# Copy into a custom target directory
    +openapi-first scaffold crud_app my-project/crud
    +
    +
    +

    Protip: DEFAULT_TEMPLATE is health_app, so openapi-first scaffold with no template name scaffolds the health app.

    +
    +
    +

    🧩 4. Anatomy of a Scaffolded Service

    +

    After openapi-first scaffold health_app my-health-service, your directory contains a drop-in FastAPI service:

    +
    1
    +2
    +3
    +4
    my-health-service/
    +├── openapi.yaml   # THE contract
    +├── main.py        # `app = OpenAPIFirstApp(openapi_path=..., routes_module=routes)`
    +└── routes.py      # `def get_health(): ...`
    +
    +

    Run it:

    +
    1
    +2
    +3
    cd my-health-service
    +pip install -e .
    +uvicorn main:app --reload
    +
    +

    /docs, /openapi.json, and every declared route now exist — all derived from openapi.yaml.

    +
    +

    ⚠️ 5. Production Disclaimer

    +

    Templates use in-memory, non-persistent, non-concurrency-safe data stores. They are learning scaffolds — not production references. Swap in a real data layer (SQL/REDIS/object store) the moment you go beyond a demo.

    +

    See the __init__.py of each template for detailed client examples, CLI examples, and design notes.

    +
    + + + + + + + + + + + + + + + +
    +
    + + + + + +

    +
    +
    + + + + +
    +
    + + + + + +

    Use Case 3: The OperationId-Driven Client

    +

    OpenAPIClient is the other side of the contract. It reads the same OpenAPI document the server runs on and exposes one callable per operationId — so "client" and "server" are two views of one truth.

    +
    +

    🔍 1. Before You Start

    +

    The client is httpx-based and returns raw httpx.Response objects — no magic deserialization, no hidden schema inference:

    +
      +
    • No response Pydantic models
    • +
    • No implicit URL construction (path params are explicit)
    • +
    • No hand-written requests.get(...) scattered through your code
    • +
    +
    +

    🧬 2. Constructing the Client

    +
    1
    +2
    +3
    +4
    +5
    from openapi_first.loader import load_openapi
    +from openapi_first.client import OpenAPIClient
    +
    +spec = load_openapi("openapi.yaml")
    +client = OpenAPIClient(spec)
    +
    +

    The base URL comes from the spec's servers list (first entry) unless you pass base_url explicitly:

    +
    client = OpenAPIClient(spec, base_url="https://api.internal.myco/v1")
    +
    +

    You can also hand over a preconfigured httpx.Client (custom transport, TLS, retries):

    +
    1
    +2
    +3
    +4
    +5
    +6
    +7
    import httpx
    +
    +transport = httpx.HTTPTransport(retries=3)
    +client = OpenAPIClient(
    +    spec,
    +    client=httpx.Client(transport=transport),
    +)
    +
    +
    +

    💥 3. Fail-Fast at Construction

    +

    OpenAPIClient(...) raises immediately if the contract is broken — you find out at startup, not on the first request:

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    ViolationError
    Spec has no servers entryOpenAPIClientError
    Spec has no pathsOpenAPIClientError
    Operation missing operationIdOpenAPIClientError
    Duplicate operationIdOpenAPIClientError
    Operation references unknown parametersOpenAPIClientError
    +

    Missing required parameters fail at call time — pydoclint-grade strictness on the wire.

    +
    +

    📞 4. Calling Operations

    +

    Every operationId becomes a method. The call signature is uniform across the whole client:

    +
    1
    +2
    +3
    +4
    +5
    +6
    +7
    +8
    response = client.<operationId>(
    +    *,
    +    path_params: dict | None = None,
    +    query: dict | None = None,
    +    headers: dict | None = None,
    +    body: Any | None = None,
    +    timeout: float | None = None,
    +) -> httpx.Response
    +
    +

    Concrete examples (from the crud_app / health_app templates):

    +
     1
    + 2
    + 3
    + 4
    + 5
    + 6
    + 7
    + 8
    + 9
    +10
    +11
    +12
    +13
    +14
    +15
    +16
    +17
    +18
    +19
    # No parameters — simplest
    +response = client.get_health()
    +assert response.status_code == 200
    +
    +# Path parameter
    +response = client.get_item(path_params={"item_id": 3})
    +
    +# Query parameters
    +response = client.list_items(query={"limit": 10, "offset": 20})
    +
    +# JSON request body
    +response = client.create_item(body={"name": "Orange", "price": 0.8})
    +
    +# Custom headers / timeout
    +response = client.get_user(
    +    path_params={"user_id": 1},
    +    headers={"X-Internal-Key": "..."},
    +    timeout=30,
    +)
    +
    +

    Returns: the raw httpx.Response, so status_code, .json(), .headers are all yours to inspect.

    +
    +

    🧠 5. How Parameters Are Bound

    +

    For each operation the client knows exactly where each parameter belongs:

    + + + + + + + + + + + + + + + + + + + + + + + + + +
    OpenAPI locationClient kwarg
    in: pathpath_params[name]
    in: queryquery[name]
    in: headerheaders[name]
    requestBodybody
    +

    JSON media types are sent as json=; other media types as raw content=.

    +
    +

    🔄 6. Server ↔ Client, One Spec

    +
    1
    +2
    +3
    # One directory, two processes
    +uvicorn main:app --port 8000                                  # server
    +python -c "import asyncio; from client_script import run; asyncio.run(run())"  # client
    +
    +

    Or the same client against a remote environment:

    +
    1
    +2
    +3
    +4
    client = OpenAPIClient(
    +    spec,
    +    base_url="https://staging.internal.myco",
    +)
    +
    +

    The URL is the only thing that changes between environments — the contract never does.

    +
    +

    ✍️ 7. OperationId as the API

    +

    Because the client is operationId-driven:

    +
      +
    • Adding an operation = adding a method (and vice versa)
    • +
    • No operation can be "forgotten" by the client — it's constructed from the spec
    • +
    • operationId is the one name you remember; the HTTP verb/path is an implementation detail
    • +
    +

    If an operationId you call doesn't exist, you get an AttributeError at construction-scan time — never a silent 404.

    TL;DR — point openapi-first codegen at your spec and get models + routes scaffolds you can bind with one line. The codegen output is deterministic, and it's a starting point — not a maintained artifact.

    +
    +
    +

    🧭 1. Why Celebrate Codegen?

    +

    Two pain points kill OpenAPI projects:

    +
      +
    1. The "write the spec, then write the same thing as Pydantic models" step — exactly where server/client param types drift (your route says item_id: int, your client sends a string…).
    2. +
    3. Writing the docs/spec catalog by hand, once you have more than a handful of operations.
    4. +
    +

    Codegen collapses both. One command, one source file, same generated shapes everywhere.

    +
    +

    🚀 2. Model Generation

    +
    openapi-first codegen models --module my_project.models --input openapi.yaml
    +
    +

    The generated model module mirrors the spec's components.schemas by name:

    + + + + + + + + + + + + + + + + + + + + + + + + + +
    SpecGenerated
    components.schemas.Userclass User(BaseModel)
    components.schemas.Itemclass Item(BaseModel)
    every $ref (schema)a type: ClassVar alias ✓
    required + type from schemaPydantic Field(...) / type hints ✓
    +

    Never hand-edit those files. If the spec changes, regenerate — just like you'd re-run cargo build after editing Cargo.toml.

    +

    Why constructor-time validation still applies

    +

    Codegen doesn't change the design: the generated models are plain Pydantic, and the client/server still validate against the spec at startup. Codegen is a convenience accelerator on top of the fail-fast guarantees in 04 – Design and 06 – Error Handling.

    +
    +

    🔁 3. Route Generation / Verification

    +
    1
    +2
    +3
    +4
    +5
    # dry-run verification against your routes module
    +openapi-first codegen routes --module my_routes --input openapi.yaml --check
    +
    +# scaffold an operation skeleton (generates the handler with a TODO)
    +openapi-first codegen routes --module my_routes --input openapi.yaml
    +
    +

    Why bother? Because bind_routes (in 02 – Components) needs an operationId → handler exactly matching the spec. Codegen guarantees you never type a handler name wrong — it wears the same operationId as the spec says.

    +
    +

    Note: codegen is build-time tooling. It does not run at runtime, and templates (the Bake-your-stuff section of 02 – Templates) make scaffolding a server out-of-the-box even simpler for greenfield projects.

    +
    +
    +

    🧪 4. Idempotent Output

    +

    Generated output is deterministic w.r.t. the spec: +- Same spec → byte-identical files (unless you hand-edit — you won't) +- Ordering follows spec declaration order +- No timestamps, no machine names, no hidden randomness

    +

    That determinism is what lets you git diff after a spec change and see exactly what moved.

    Design — Guarantees, Startup Pipeline, and the Contract Model

    +

    This page is the architecture reference: the fail-fast startup surface, the guarantees that hold by construction, and the trade-offs baked into every decision.

    +
    +

    🏗️ 1. The Startup Pipeline

    +

    Everything happens once, eagerly, at construction time — for the app at OpenAPIFirstApp(...), for the client at OpenAPIClient(...). There is no lazy loading, no deferred binding, no "it'll work on first request".

    +    │    └─ missing / duplicate opId ──► OpenAPIClientError
    +    └─► ready
    +
    +
    +

    📜 2. Guarantees That Hold by Construction

    +

    These are not conventions — they are enforced at startup or client construction:

    +
      +
    1. Every route is spec-declared. Routes are registered only from paths; there is no decorator-driven or implicit routing.
    2. +
    3. Every operation is handled. Each operationId resolves to an exact handler name in routes_module; a missing one aborts bootstrap.
    4. +
    5. Every operation has an operationId. An operation without one cannot be bound and fails fast.
    6. +
    7. Client and server use the same spec. One document drives both sides, so they cannot drift.
    8. +
    9. Auth is spec-driven. security dependencies come from securitySchemes + per-operation security; no manual middleware.
    10. +
    11. Spec is valid before use. Invalid, malformed, or unloadable specs are rejected at load, not at first request.
    12. +
    +

    The startup "no half-states" property

    +

    Because binding, validation, and security resolution all run at construction, a booted app is a provably-complete app. If the contract is violated in any way, the process refuses to start — the failure is loud, immediate, and tells you exactly what to fix.

    +
    +

    🧩 3. Component Responsibilities

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    ModuleOwnsRefuses to

    securityschemes → FastAPI Dependsmanual middleware
    errorsthe error hierarchyswallow failures
    codegenbuild-time model/routes generationruntime codegen
    templatescopyable scaffoldsproduction data stores
    +

    Rule of thumb for contributors: keep modules coercive (they raise if the contract is wrong) and narrow (one responsibility each). Pydoclint + the test suite keep that contract honest.

    +
    +

    ⚖️ 4. Design Trade-offs (Accepted)

    Security — Auth Driven by the Spec, Not by Hand

    +

    The most distinctive thing about openapi-first security is that you never write middleware or Depends(authenticate) calls yourself. All authentication is declared in the OpenAPI document and enforced automatically.

    +
    +

    🗺️ 1. Where Security Lives

    +

    Two places in the spec, both respected:

    +

    1.1 components.securitySchemes — the inventory

    +
    1
    +2
    +3
    +4
    +5
    +6
    +7
    +8
    components:
    +  securitySchemes:
    +    internalBearer:
    +      type: http
    +      scheme: bearer
    +      bearerFormat: JWT
    +      x-server-url: "{AUTH_SERVER_URL}"
    +      x-introspect-path: "/introspect"
    +
    +

    x-server-url and x-introspect-path are library extensions that point at a JWT introspection endpoint (see Introspection).

    +

    1.2 security — per-operation (or global) requirements

    +
     1
    + 2
    + 3
    + 4
    + 5
    + 6
    + 7
    + 8
    + 9
    +10
    +11
    security:
    +  - internalBearer: []          # applied to every operation by default
    +
    +paths:
    +  /pets:
    +    get:
    +      operationId: list_pets
    +      # inherits: security: [{internalBearer: []}]
    +    post:
    +      operationId: create_pet
    +      security: []              # override — public endpoint
    +
    +

    OpenAPI dynamic-scoping rules apply: an operation-level security replaces the global list (it does not merge).

    +
    +

    📖 2. Reading the Spec

    +

    security.py exposes two functions:

    + + + + + + + + + + + + + + + + + + + + +
    FunctionReturnsPurpose
    parse_security_schemes(spec)dict[str, dict]Collect schemes, resolve {ENV_VAR} placeholders
    make_security_dependencies(spec, schemes)dict[str, list[Depends]] (keyed METHOD:/path)Effective per-operation security deps
    +

    Env placeholders of the form {NAME} are resolved once at startup from os.environ. This is how you avoid embedding credentials or auth-service URLs in the committed spec.

    +
    +

    🔐 3. The Bearer Dependency

    +

    make_security_dependencies builds a FastAPI dependency for type: http, scheme: bearer.

    +

    Two modes, decided by whether an introspection endpoint is configured:

    +

    3.1 With introspection (x-introspect-path)

    +
      +
    • Reads Authorization: Bearer <token>
    • +
    • POSTs {"token": "<token>"} to {x-server-url}{x-introspect-path} synchronously via the bundled httpx client
    • +
    • Expects a response with active: true
    • +
    • On valid: {"user": ...} from the introspection body → request.state.user
    • +
    • On failure: 401 (missing/invalid token) or 503 (auth service unreachable)
    • +
    +

    3.2 Without introspection

    +
      +
    • Validates only that a Bearer token is present
    • +
    • Stores it on request.state.token; no remote call
    • +
    +
    +

    +
    +spec = load_openapi("openapi.yaml")
    +schemes = parse_security_schemes(spec)
    +security_deps = make_security_dependencies(spec, schemes)
    +
    +app = OpenAPIFirstApp(
    +    openapi_path="openapi.yaml",
    +    routes_module=routes,
    +)
    +
    +

    OpenAPIFirstApp already does this internally — the snippet above shows what it encapsulates (and what you use directly if you assemble the pieces by hand).

    +
    +

    🧪 5. Testing Security

    +

    Because handlers are plain callables, security is the one place FastAPI's TestClient earns its keep:

    +def test_unauthenticated_is_401(app, overrides):
    +    with TestClient(app) as client:
    +        r = client.get("/pets")
    +        assert r.status_code == 401
    +
    +def test_invalid_token_using_fake_introspector(app):
    +    # Point x-introspect-path at a stub uvicorn/TestServer returning active:false
    +    with TestClient(app) as client:
    +        r = client.get("/pets", headers={"Authorization": "Bearer nope"})
    +        assert r.status_code == 401
    +
    +

    See Testing for the full recipe, including how tests stub the introspection server.

    Error Handling — Fail Loud, Fail Early

    +

    openapi-first treats errors as first-class contract documents: every failure mode is a named exception with a stable import pathhare, and every one surfaces as early as possible.

    +
    +

    🧬 1. The Hierarchy

    +

    All errors derive from OpenAPIFirstError (in openapi_first/errors.py), so a single except OpenAPIFirstError catches every first-party failure:

    +
    1
    +2
    +3
    +4
    +5
    +6
    +7
    OpenAPIFirstError
    +├── OpenAPISpecError                     # spec-level problems
    +│   └── OpenAPISpecLoadError             # load / parse / validation  (loader)
    +├── OpenAPIClientError                   # client-side contract issues (client)
    +└── MissingOperationHandler              # spec op with no handler     (binder)
    +
    +# Security / loader layers raise through OpenAPISpecError subclasses too
    +
    + + + + + + + + + + + + + + + + + + + + + + + + + +
    ExceptionModuleRaised when
    OpenAPISpecLoadErrorloaderPath missing, file unreadable, YAML/JSON invalid, or spec fails OpenAPI 3.x validation
    OpenAPIClientErrorclientNo servers, no paths, missing/duplicate operationId, missing required params at construction
    MissingOperationHandlererrorsAn operation is declared whose operationId has no matching handler in routes_module
    +
    +

    ⏱️ 2. When Things Fail

    +

    The single most important rule: violations are eager, not lazy.

    +

    2.1 At application startup

    +
    1
    +2
    +3
    # openapi.yaml missing ────────────────────────────► OpenAPISpecLoadError
    +# operationId without a handler ───────────────────► MissingOperationHandler
    +# operation with no operationId declared ──────────► MissingOperationHandler
    +
    +

    Because these raise during OpenAPIFirstApp(...) construction, CI catches them the moment a spec and its routes drift — before a single request is served.

    +

    2.2 At client construction

    +
    OpenAPIClient(spec)  # fails fast, same philosophy
    +
    +
      +
    • Spec with no serversOpenAPIClientError
    • +
    • Spec with no pathsOpenAPIClientError
    • +
    • Duplicate operationIds → OpenAPIClientError (client methods must be unambiguous)
    • +
    • Operation missing operationIdOpenAPIClientError
    • +
    +

    2.3 At call time (client)

    +

    Runtime transport errors surface as httpx exceptions (httpx.RequestError family), not swallowed or remapped. Missing required args fail before any HTTP request is made:

    +
    1
    +2
    client.get_user(path_params={"user_id": ...})     # OK
    +client.get_user()                                  # ValueError — user_id required
    +
    +
    +

    🧰 3. Handling in Your App

    +

    3.1 Server-side

    +

    Handlers raise FastAPI HTTPException for expected operation-level failures (404/422), and the OperationId-binding errors only exist at startup:

    +
     1
    + 2
    + 3
    + 4
    + 5
    + 6
    + 7
    + 8
    + 9
    +10
    +11
    +12
    +13
    +14
    +15
    +16
    +17
    from fastapi import HTTPException
    +
    +def get_item(item_id: int):
    +    """Retrieve an item by ID.
    +
    +    Implements the OpenAPI operation ``get_item``.
    +
    +    Args:
    +        item_id (int): Identifier of the item.
    +
    +    Raises:
    +        HTTPException: If the item does not exist (404).
    +    """
    +    try:
    +        return _get_item(item_id)
    +    except KeyError:
    +        raise HTTPException(status_code=404, detail="Item not found")
    +
    +

    3.2 Client-side

    +
    1
    +2
    +3
    +4
    +5
    +6
    import httpx
    +
    +try:
    +    response = client.get_item(path_params={"item_id": 1})
    +except httpx.HTTPStatusError as exc:
    +    ...  # 4xx/5xx from the server
    +
    +

    httpx.HTTPStatusError isn't raised by the library — it's the standard httpx.raise_for_status() you can opt into per call. The library never masks a response code.

    +
    +

    🛡️ 4. Fail-Fast Guarantees Recap

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    LayerYou writeThe library guarantees
    Loadera spec pathunreadable/invalid specs never reach your app
    Binderhandler functionsevery operation must resolve, or the app won't start
    Clienta specevery operationId becomes a callable; missing ones fail at construction
    Runtimehandler codeFastAPI + Pydantic handle coercion; contract checks already happened at startup
    +

    None of these can silently degrade: a violation is an exception at construction, not a 500 at request time.

    Testing — Smoke-First, Contract-First

    +

    Everything openapi-first ships is tested against real specs, real handlers, and real HTTP through FastAPI's TestClient and the bundled templates. There are no fakes of the library itself.

    +
    +

    +    path = tmp_path / "openapi.json"
    +    path.write_text(json.dumps(SPEC), encoding="utf-8")
    +    return str(path)
    +
    +@pytest.fixture
    +def app(spec_file):
    +    return OpenAPIFirstApp(
    +        openapi_path=spec_file,
    +        routes_module=routes_module(),
    +    )
    +
    +@pytest.fixture
    +def client(spec_file):
    +    return OpenAPIClient(json.loads(Path(spec_file).read_text()))
    +
    +
    +

    🧪 3. What's Actually Asserted

    +

    3.1 App-level smoke

    +
    1
    +2
    +3
    +4
    def test_app_routes_served(spec_file):
    +    app = OpenAPIFirstApp(openapi_path=spec_file, routes_module=routes)
    +    client = TestClient(app)
    +    assert client.get("/health").json() == {"status": "ok"}
    +
    +

    3.2 Fail-fast (the heart)

    +
    1
    +2
    +3
    def test_app_missing_handler_fails_at_startup(spec_file):
    +    with pytest.raises(MissingOperationHandler):
    +        OpenAPIFirstApp(openapi_path=spec_file, routes_module=empty_routes)
    +
    +

    3.3 Loader validation

    +
    1
    +2
    +3
    def test_loader_invalid_spec_fails():
    +    with pytest.raises(OpenAPISpecLoadError):
    +        load_openapi("broken.yaml")
    +
    +

    3.4 Client contract drift

    +
    1
    +2
    +3
    def test_client_duplicate_operation_id_raises():
    +    with pytest.raises(OpenAPIClientError):
    +        OpenAPIClient(dup_spec)
    +
    +
    +

    🏛️ 4. Testing the Templates

    +

    Each bundled template ships its own test + in-memory store, so you get a runnable contract test the moment you scaffold:

    +
    1
    +2
    +3
    openapi-first scaffold crud_app my-service
    +cd my-service
    +pytest -q
    +
    +

    test_crud_app.py / test_model_app.py / test_vet_app.py exercise the full CRUD surface through TestClient — including 201/204 status codes, 404s, and (in vet_app) SSE streaming via StreamingResponse.

    +
    +

    🕹️ 5. Quality Gates (CI)

    +

    The same gates the library itself must pass are what keep the docs honest:

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    GatePurpose
    black --checkformatting parity
    ruff checklint hygiene
    mypytype safety (strict, --disable-error-code where intentional)
    pytest23 tests, green
    coveragetracked via pytest-cov (HTML + XML + term)
    +

    Run the whole gate locally:

    +
    1
    +2
    +3
    +4
    black --check openapi_first tests
    +ruff check openapi_first tests
    +mypy openapi_first
    +pytest
    +
    +
    +

    💡 6. Testing Tips

    +
      +
    • Start from startup: assert OpenAPIFirstApp(...) raises for the broken contracts — those are your most valuable tests
    • +
    • Client ↔ server: smoke a client against the same spec the app was built from — one spec, two sides, zero drift
    • +
    • Templates are scaffolds: their tests are copyable starting points, not canonical suites
    • +
    • No mocking of the library: exercise loader → binder → app → client as a real pipeline
    • +

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param observerOrNext Either an {@link Observer} with some or all callback methods,\n * or the `next` handler that is called for each value emitted from the subscribed Observable.\n * @param error A handler for a terminal event resulting from an error.
