Need sample code (swagger+node+mssql) to see how to setup connection and make CRUD call to real DB

Already have a project using swagger+node.js, now I need to call a stored procedure and pass in parameters, I just have no idea how to integrate it with my existing code (separate POC project works fine). Sample swagger doc or nodejs code will be sufficient, as long as it is sample /psudo code to make a connection to real mssql DB. All the examples I found are using in-memory JSON to mimic CRUD POST/GET, but I need to see how it is set up in swagger or node. Thanks in advance.
