Ballerina-OpenAPI

The OpenAPI Specification is a specification, which creates a RESTFUL contract for APIs detailing all of its resources and operations in both human and machine-readable format for easy development, discovery, and integration. Ballerina OpenAPI tooling will make it easy for users to start the development of a service documented in the OpenAPI contract by generating the Ballerina service and client skeletons. The OpenAPI tools provide the following capabilities.

1. Generate the Ballerina service or client code for a given OpenAPI definition.
2. Export the OpenAPI definition of a Ballerina service.
3. Validate the service implementation of a given OpenAPI contract.

The openapi command in Ballerina is used for OpenAPI to Ballerina and Ballerina to OpenAPI code generations. The OpenAPI compiler plugin will allow you to validate a service implementation against an OpenAPI contract during compile time. This plugin ensures that the implementation of a service does not deviate from its OpenAPI contract. For more information on the supported operations, go to Using the OpenAPI Tools
