One plan covers every Professional Certificate on Coursera.

This course covers the essential concepts of Node.js, emphasizing its event-driven architecture and significance in modern backend development. Professionals will understand how Node.js enables scalable, non-blocking applications. Learners will explore the module system, callbacks, and asynchronous control flow, building skills to write maintainable, efficient Node.js code. Practical exercises reinforce each concept, helping participants apply techniques to real-world projects. What sets this course apart is its focus on combining theory with hands-on examples. Students learn both the principles and practical implementations of callbacks, promises, and async/await patterns in real Node.js workflows. This course benefits developers, programmers, and anyone with basic JavaScript knowledge looking to deepen their backend skills. No prior Node.js experience is required, but familiarity with JavaScript is recommended. This course is part one of a three-course Specialization designed to provide a comprehensive learning pathway in this subject area. While it delivers standalone value and practical skills, learners seeking a more integrated and in-depth progression may benefit from completing the full Specialization.

Syllabus

The Node.js Platform

This module introduces the foundational concepts of Node.js, including its asynchronous architecture, the reactor pattern, and the philosophy guiding its development. Learners will explore how Node.js leverages non-blocking I/O and JavaScript to build scalable, high-performance server-side applications. The module also covers the integration of native code for enhanced functionality.

The Module System

This module delves into the fundamentals of module systems in Node.js, covering ES modules, CommonJS, and the revealing module pattern. Learners will explore module resolution, dependency management, and interoperability between different module systems, including considerations for TypeScript projects. By the end, you'll understand how to organize, import, and export code efficiently while handling advanced scenarios like circular dependencies.

Callbacks and Events

This module delves into the use of callbacks and the Observer pattern in Node.js, highlighting both synchronous and asynchronous programming techniques. Learners will discover best practices for designing APIs, handling errors, and combining callbacks with events to build robust, reactive applications.

Asynchronous Control Flow Patterns with Callbacks

This module delves into asynchronous programming in Node.js, focusing on callback patterns and control flow techniques. Learners will tackle common challenges such as callback hell, and explore sequential, concurrent, and limited concurrent execution using practical examples like a web spider application. By the end, you'll be able to manage complex asynchronous tasks efficiently and write more maintainable code.

Asynchronous Control Flow Patterns with Promises and Async/Await

This module introduces the concepts and practical applications of promises and async/await for managing asynchronous operations in Node.js. Learners will explore sequential and concurrent execution patterns, error handling strategies, and common pitfalls in asynchronous programming. By the end, you'll be able to write cleaner, more efficient asynchronous code using modern JavaScript techniques.
