NodeJS Training

Node.js is a platform for easily building fast, scalable network applications. Learn how to use the event-driven, non-blocking I/O model to build data-intensive real-time applications that run across distributed devices.

Objectives

On completion of this course, the learner will be able to:

  • Clearly, understand the platform design choices that led to Node.js choosing an event loop and what this means for applications built on that foundation.
  • Understand the unique trade-offs present in event-driven programming.
  • Create Node.js modules and express code modularity in an application.
  • Understand the core flow control patterns in Node.js and know when it is appropriate to use callbacks, event emitters or streams.
  • Create and manipulate buffers efficiently.
  • Understand how to manage error state and know when a process should exit due to an error.
  • Build network applications with Node.js.
