However JSON Schema specification says it's pretty valid to add custom keywords like this: Is there a way to add a configuration and create models with Date as a type where format is date-time? This is the script that I use to launch the generation: "generate": "openapi-generator-cli generate -g typescript-angular -i openapi. Below, we will step through the different types available in OpenAPI and explain how to use formats, patterns and additional attributes to give you a spec that is descriptive and explicit.
