So I've documented my whole API with swagger editor, and now I have my .yaml file. I'm really confused how I take that and generate the whole nodejs stuff now so that all those functions are already defined and then I just fill them in with the appropriate code.
Swagger Codegen generates server stubs and client SDKs for a variety of languages and frameworks, including Node.js.
To generate a Node.js server stub, run codegen with the -l nodejs-server argument.
Windows example:
java -jar swagger-codegen-cli-2-2-2.jar generate -i petstore.yaml -l nodejs-server -o .\PetstoreServer
You get:
