OpenApiSpecToModelConverter is a .NET tool designed to convert OpenAPI specifications into strongly-typed type script models, making it easier to integrate APIs into your .NET or client side applications.
To install the OpenApiSpecToModelConverter tool globally, use the following command:
dotnet tool install -g OpenApiSpecToModelConverterOnce the tool is installed, you can use it to generate models from an OpenAPI specification file (YAML format).
generate-model --InputFile <path-to-openapi-spec> --OutputFileName <output-filename>- 
--InputFileor-i: Specifies the path to the OpenAPI specification file. This can be a local file path or a URL to the specification.
- 
--OutputFileNameor-o: Specifies the output file name where the generated models will be saved.
Here’s an example command that converts an OpenAPI spec located at ./openapi.yaml into Type script models in the output file:
generate-model --InputFile ./openapi.yaml --OutputFileName output
