Swagger question

'm trying to create my own REST API with Swagger, Postman, and DreamFactory - I create a JSONv1 file from POSTMAN and exported it to Swagger as a YAML - Then from swagger, I created a package. I tried using the index.js file as the config in dreamfactory, but there are no functions in it that actually perform operations on the data - there are 4 subdirectory .js files in my package. I’m not sure waht they do, I beleive they are what I’m looking for, some say authorize etc… My question is this - is there somesort of node.js script generator that will actually perform the operations in the script? or do i need to create my own fileOr, if someone can explain to me how to ouse these .js in the subdirectories with dreamfactory
