This module will take away the pain of writing API and Data Model documentation for your Express & Mongoose based REST API. It auto-generates API documentation from the code on runtime so the documentation always stays up to date.
npm install express-mongoose-docs
Add these lines to your app.js file
var docs = require("express-mongoose-docs");
Make sure the following line comes after all express middleware such as app.use(express.bodyParser());
docs(app, mongoose); // 2nd param is optional
That's it. The Docs web page should be accessible at Your-Base-URL/apiDocs
Example: http://localhost:5000/apiDocs
