Is it possible to generate schema from openapi json file

Is it possible to generate a schema from a openapi swagger json file.

Hi @hari-nair-on, could you clarify what kind of schema you'd like to generate?

The LoopBack 4 CLI can generate an OpenAPI client in an existing LoopBack 4 project using lb4 openapi --client. This is useful for linking a LoopBack 4 project to existing OpenAPI 2/3.0-documented APIs.

For generating an OpenAPI 3.0 spec of the current LoopBack 4 project: By default, the /openapi.json is exposed when the server is running, and npm run openapi-spec can be used to directly export it to a file.

Thanks for the reply. Really appreciated. I am using loopback 4. Created a datasource [lb4 datasource] and poiinted towards a json file which is created by openapi spec. I am trying to create a scehema using that json file either wholly or partially. What is the best way to do this. To show a controller for crud we need a model right. How can i create a model out of this. The json file already have valid fields to create a model. It is possibly a tedious task if the json file is large enough. Any practical idea how can i achieve this.
