Course Description

Node.js (Node) is an open-source, cross-platform, runtime environment that allows
JavaScript – to run outside of the browser. Node plays a key role in cutting edge, modern
usage of JavaScript and related frameworks such as Angular and React. Node has
become an integral part of both development and production environments.

Developers can leverage many provided libraries to create desktop and server
applications that work with the file system and HTTP. A multitude of tools can help to
create various applications quickly using best practices.

This course combines lecture and hands-on exercises to get students up to speed quickly.
Students will work with core modules of Node.js, and explore popular modules such as
lodash, moment and Express. During the course students will develop a Rest API using
Express. This course uses Postgres as a relational database but can be customized
