This lightweight module provides an easy interface for the Steam Community website. This module can be used to simply login to steamcommunity.com for use with other libraries, or to interact with steamcommunity.com.
It supports Steam Guard but doesn't support CAPTCHAs, so make sure you don't provide Steam with an incorrect password.
Install it from npm:
$ npm install steamcommunity
As of version 1.0.0, documentation is on the GitHub wiki.
