Build REST API using Node.js Training Course

Overview

Node.js is a platform for easily building fast, scalable network applications. This course will provide government professionals with the skills needed to leverage the event-driven, non-blocking I/O model to build data-intensive real-time applications that run across distributed devices. We will explore the design choices that make Node.js unique and how this changes the way applications are built and systems of applications operate most effectively in this model. Participants will learn how to create modular code that is robust, expressive, and clear. They will understand when to use callbacks, event emitters, and streams. The course also covers using streams to efficiently manipulate data that would be impossible to fit into application memory. Additionally, participants will gain confidence in handling errors effectively to ensure runtime reliability. Extensive lab exercises are included to reinforce the concepts and techniques covered.

Objectives

On completion of this course, students 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, particularly for government use cases.
• Understand the unique trade-offs present in event-driven programming and how they apply to public sector workflows.
• Create Node.js modules and express code modularity in an application, ensuring alignment with governance and accountability standards.
• Understand the core flow control patterns in Node.js and know when it is appropriate to use callbacks, event emitters, or streams in a government context.
• Create and manipulate buffers efficiently, optimizing performance for government applications.
• Understand how to manage error state and determine when a process should exit due to an error, ensuring reliability in public sector systems.
• Build network applications with Node.js that meet the stringent requirements of government operations.
