Node.js: Building Professional JavaScript Backends

Serverside JavaScript done right

Description

Node.js brings JavaScript to the server and enriches her with diverse arrangement of APIs.

In this training, you'll learn Node.js inside and out. We'll work with everything Node has to offer, as well as what's present in the ecosystem. This includes filesystem operations and setting up a low-level (web)server, but also the use of web frameworks and talking to a database through an abstraction layer. Along the way, interesting historical moments will be shared, as well as experiences and best practices.
