What it is and what it does
bravado-core is a Python library that implements client-side and server-side support for OpenAPI Specification v2.0 (formerly Swagger). It provides schema validation, request/response marshaling and transformation, and custom type conversion through a pluggable format system. The library represents API models as either Python classes or dictionaries, making it suitable for both strongly-typed and flexible use cases.
The package depends on jsonschema for schema validation, requests for HTTP operations, pyyaml for configuration parsing, and several utility libraries for date handling and serialization. It is actively maintained, supports Python 3.8 through 3.11, and has no known security vulnerabilities. The library is intended for developers building OpenAPI-compliant clients or servers who need robust schema validation and data transformation.
Use it for
- Validate incoming API requests and responses against an OpenAPI v2.0 schema in a server application.
- Marshal Python objects to and from JSON/YAML request and response bodies with automatic type conversion.
- Build a Python client that enforces OpenAPI schema constraints during request construction.
- Define custom format handlers to convert between OpenAPI types and Python domain objects.
- Integrate OpenAPI schema validation into a REST framework or API gateway.
