This document provides an overview and roadmap for an introductory course on Node.js. The course will cover Node basics, building web servers with Express.js, using MongoDB and Mongoose for the database, and building both simple and more complex applications. Expectations are a familiarity with JavaScript, databases, and basic web development principles. Asynchronous programming and the event loop model will also be discussed.
