Built this as a quick test for using OAPI Codegen tool and building out a scalable API from the generated code. I used the Chi library to handle routing. Everything is tied together in the main function, and the server is hosted on port 8080.
The generated code lives in the generated package.
The code for handling requests lives in the handler package.
In the handler package, the handler.go file contains the implementation of the generated.ServerInterface, while the data.go file contains the logic to interact with the data source (in this example, it's a simple slice on the impl struct)
Let me know if you have any questions!
