What's new in this version

A lot of improvements and fixes.
Thank you Theo !


  • Add support for OpenAPI additionalProperties #32
  • Make sure responses other than 20x are also handled! #24
  • Allow generating GenericReponse as common message #22
  • Add support for "application/x-www-form-urlencoded"; generate new utility class util.UrlEncodedRequest #18
  • Allow suppressing of required qualifier, instead add “required” as part of description! #17


  • Do not call SetParam for empty query variable #38
  • Move set path parameter in dispatch class #36
  • Make sure the description from responses is also generated as a comment #23
  • Request classes - Add MAXLEN="" for path properties and %URL #20

This package gather a set of tools for ObjectScript code generation from Swagger specification 3.0.

It includes :

The following features are available :

  • Web interface to generate the code.
  • REST services to expose code generation.
  • Automatic conversion of Swagger specification 1.x or 2.x to version 3.x before processing (using swagger-converter-cli ).

OpenAPI-suite can generate code :

  • Simple HTTP client
  • Production client (with business services, processes and operation)
  • Server-side REST classes.

Installation ZPM

zpm "install openapi-suite"
; optional
zpm "install swagger-ui"

Installation docker

git clone git@github.com:lscalese/openapi-suite.git
cd openapi-suite
# in case of permission issue with iris-main.log
# touch iris-main.log && chmod 777 iris-main.log
docker-compose up -d

Important : If you use url to a specification accessible only from your network \ organization use the docker-compose that include
validator and converter tools instead of the default docker-compose.yml:

docker-compose --file docker-compose-with-swagger.yml up -d

It seems a problem could be occurs with BuildKit on Ubuntu.
In this case, you should use the compose plugin with the command docker compose up -d plugin instead of docker-compose up -d.
See the official documentation to instal compose plugin : Install the Compose plugin | Docker Documentation


Web interface

The UI is available at this address(*) http://localhost:52796/openapisuite/ui/index.csp

By default the feature Install On Server is disabled.
To enable, just :

Set ^openapisuite.config("web","enable-install-onserver") = 1

(*) Adapt the port number if needed


If you install swagger-ui, you can open http://localhost:52796/swagger-ui/index.html and explore
http://localhost:52796/openapisuite/_spec to test REST services.

Generate by programming

All code snipets are available in the class dc.openapi.suite.samples.PetStore

Simple HTTP client

Set sc = ##class(dc.openapi.suite.Generate).Client("petstore.client", "https://petstore3.swagger.io/api/v3/openapi.json")

Production client

Set sc = ##class(dc.openapi.suite.Generate).ProductionClient("petstore.production","https://petstore3.swagger.io/api/v3/openapi.json")

Rest server-side classes

Set sc = ##class(dc.openapi.suite.Generate).Server("petstore.server", "https://petstore3.swagger.io/api/v3/openapi.json")

Code generation with a specification contains external references

If the input of your specification is a URL, the parser will resolve automatically external references like:


Howewer, the name of the model is auto generated and there is way to have a better result.
Start to generate models from the referenced specification, then map the “$ref” with the model package before generate your app, example:

; Generate models from referenced specification
Set sc = ##class(dc.openapi.suite.Generate).Models("Nuts.Api.Common", "https://nuts-node.readthedocs.io/en/stable/_static/common/ssi_types.yaml")

; Set a mapping specifcation - models
Set externals = {"../common/ssi_types.yaml": "Nuts.Api.Common.model"}

; Generate your application with a mapping model for external references.
Set sc = ##class(dc.openapi.suite.Generate).Server("Nuts.ApiServer.DidManager", "https://nuts-node.readthedocs.io/en/stable/_static/didman/v1.yaml", , externals)

Note: If you use a filepath instead of a URL, the solution above is the only way.

The features argument

The code generation methods described above can take 3rd argument features, this is an array with the following supported key-value:

Set features("noExtRef") = 1    ; avoid resolving external references by the parser.

; The following key\value make sense for ProductionClient generator:
Set features("noBS") = 1 ; no business service class generation
Set features("noBP") = 1 ; no business process class generation
Set features("noUtils") = 1 ; no utils class generation

; Example:
Set sc = ##class(dc.openapi.suite.Generate).ProductionClient("petstore.production","https://petstore3.swagger.io/api/v3/openapi.json", .features)
