v1.0.0b1

Added

• Dependency Injection system with Depends and Security for automatic dependency resolution
  • Request-scoped caching (same dependency called multiple times returns cached result)
  • Circular dependency detection
  • SecurityScopes injection for OAuth2 scope validation
  • Generator/yield dependencies with proper cleanup (sync and async)
• FastAPI-style parameter classes: Query, Path, Header, Cookie, Body, Form, File
  • Full Pydantic v2 validation: gt, ge, lt, le, min_length, max_length, pattern, multiple_of, strict, etc.
  • Parameter metadata: description, title, example, examples, deprecated
  • Alias support for headers and query parameters
• Django support with DjangoRouter (sync) and DjangoAsyncRouter (async), including urls property for Django URL patterns
• Falcon async support with FalconAsyncRouter (in addition to existing sync FalconRouter)
• FileUpload class for framework-agnostic file handling with .read() and .aread() methods
• Form data and file upload extraction for all frameworks
• RequestData unified container for request data across all frameworks
• Response class for custom responses with headers and status codes
• Response model validation via TypeAdapter with thread-safe caching
• Standardized error hierarchy: APIError, BadRequestError, ValidationError (422), AuthenticationError, AuthorizationError, ResourceNotFoundError, ResourceConflictError, InternalServerError, ServiceUnavailableError, DependencyError, CircularDependencyError, SecurityError
• APIError.from_exception() for converting any exception to standardized JSON format
• EXCEPTION_MAPPER on routers for framework-specific exception conversion (e.g., Django's PermissionDenied → AuthorizationError)
• Built-in OpenAPI security schemes: Bearer JWT, API Key (header/query), Basic Auth, OAuth2
• Custom security schemes via security_scheme parameter (accepts SecuritySchemeType enum or raw dict)
• Security scheme merging in include_router()
• SecuritySchemeType exported from fastopenapi for public use
• Documentation completely rewritten with guides, API reference, framework-specific pages, and examples

Changed

• Complete architecture refactor from monolithic base_router.py to composition-based modular design:
  • core/ — BaseRouter, parameter classes, dependency resolver, types, constants
  • resolution/ — ParameterResolver (extracted from BaseRouter.resolve_endpoint_params())
  • response/ — ResponseBuilder (extracted from BaseRouter._serialize_response())
  • openapi/ — OpenAPIGenerator, SchemaBuilder, UI renderers (extracted from BaseRouter.generate_openapi())
  • errors/ — error hierarchy (extracted from error_handler.py)
  • routers/ — BaseAdapter + per-framework packages with separate extractors
• All framework routers now inherit from BaseAdapter instead of BaseRouter
• Each framework router split into separate router and extractor modules
• Route metadata stored in RouteInfo class (was tuple)
• Validation errors now return HTTP 422 (was 400)
• OpenAPI summary resolved from route metadata or formatted endpoint name; description from metadata or docstring
• Improved import errors with MissingRouter raising ImportError when framework is not installed
• django added as optional dependency extra

Deprecated

• Importing from fastopenapi.error_handler module (use from fastopenapi.errors import ... instead)

Removed

• BaseRouter.generate_openapi() method (use router.openapi property)
• BaseRouter.resolve_endpoint_params() and BaseRouter._serialize_response() internal methods
• Multi-language documentation (single English version retained)

v0.7.0

Changed

• Replaced json.dumps/json.loads with pydantic_core to_json/from_json
• _serialize_response: model list mapping now handled by Pydantic instead of manual recursion

Fixed

• Issue with parsing repeated query parameters in URL.

Removed

• The use_aliases from BaseRouter and reverted changes from 0.6.0.

v0.6.0

Added

• The use_aliases parameter was added to the BaseRouter constructor. Default is True. To preserve the previous behavior (without using aliases from Pydantic), set use_aliases=False.

Changed

• The _serialize_response method is now an instance method (was a @staticmethod) — to support use_aliases.
• The _get_model_schema method was temporarily changed from a @classmethod to a regular method — for consistent behavior with use_aliases.

Deprecated

• use_aliases is deprecated and will be removed in version 0.7.0.

v0.5.0

Added

• AioHttpRouter for integration with the AioHttp framework
• Class-level cache for model schemas
• response_errors for routers
• error_handler for standard error responses
• Some python types as response_model (int, float, bool, str)

v0.4.0

Added

• ReDoc UI and default URL (host:port/redoc)
• TornadoRouter for integration with the Tornado framework

Changed

• Revised and updated all tests.

Fixed

• Status code for error response fixed: 422 -> 500

Removed

• Removed the add_docs_route and add_openapi_route from BaseRouter.

v0.3.1

Fixed

• router imports ModuleNotFoundError

v0.3.0

Added

• QuartRouter for integration with the Quart framework.
• Initial Documentation

Changed

• Import of routers. You can use from fastopenapi.routers import YourRouter

Fixed

• Fixed retrieving parameters for BaseModel as arguments in GET routes.

v0.2.1

Fixed

• Fixed an issue in _serialize_response where BaseModel was converted to a dictionary incorrectly.
• Resolved a bug causing DataLoader to crash when processing empty datasets.
• Added tests.
• Added CHANGELOG.md.

v0.2.0

Added

• Implemented resolve_endpoint_params in BaseRouter.
• Added the prefix parameter to the include_router method.
• Implemented status_code support for responses.

Changed

• Refactored all routers.

Removed

• Removed the register_routes method from Starlette.

v0.1.0

Added

• Initial release of FastOpenAPI.
• Implemented core modules: base, falcon, flask, sanic, starlette.
• Added basic documentation and tests.
