Starting with Node.js and CouchDB without libraries like nano or cradle

Possible duplicate:
Getting bad_request invalid_json error when trying to insert a document into CouchDB from Node.js

Highest voice response on CouchDB and Node.js - Which module do you recommend? recommends not using libraries like nano or cradle starting with Node.js and CouchDB.

However, I did not find a tutorial on how to perform standard operations for all DBMSs, such as creating a database, creating a table, adding and viewing data, etc. programmatically.

EDIT: (partial answer) after installing and running CouchDB go to http://localhost:5984/_utils/script/couch.js.
