A Swagger (OpenAPI) 2.0 definition can be converted to or from an FSD file using the fsdgenswagger command-line tool.
fsdgenswagger is a command-line tool that converts Swagger to FSD or FSD to Swagger.
Install fsdgenswagger as documented from its NuGet package.
fsdgenswagger accepts an FSD file or a Swagger file as input and generates an FSD file or a Swagger file as output. It supports the standard command-line options as well as the following additional command-line options:
--fsd: Generates an FSD file (instead of a Swagger file).--json: Generates JSON (instead of YAML) when generating a Swagger file.--service-name <name>: Overrides the service name.This section describes the Swagger fields supported by Facility and their equivalent in FSD.
Not every feature in Swagger is supported. Facility API information without a corresponding Swagger field is stored in an extension field (starts with x-).
Facility does not currently support $ref fields that span files.
Facility supports both JSON and YAML formats for a Swagger definition file.
Defines the service.
