ECMAScript Modules in Node.js

Modern JavaScript development relies heavily on efficient module systems to keep codebases clean, maintainable, and fast. Understanding how to transition from CommonJS to ECMAScript Modules (ESM) is essential for any developer working with modern Node.js environments. This text-based course guides you through the foundational concepts and practical implementation of ESM, ensuring your applications are built on a future-proof architecture. By completing this course, you will confidently structure your backend applications using native import and export syntax, manage asynchronous module loading, and resolve common interoperability challenges between different module formats. What you'll learn: - Understand the core differences between CommonJS and ECMAScript Modules - Configure Node.js environments to support native ESM syntax natively - Import and export functions, classes, and variables using static analysis patterns - Manage asynchronous module loading and dynamic imports for optimized performance - Resolve interoperability issues when combining ESM with legacy CommonJS packages - Practice modern packaging conventions and module resolution rules We begin with essential terminology, exploring how module loaders parse code, before moving into step-by-step written exercises that build your practical configuration and coding skills. This course is designed for beginner to intermediate developers who have a basic grasp of JavaScript and Node.js but want to align their workflow with modern industry standards. No prior experience with ESM configuration is required. Start reading today to modernize your JavaScript development workflow.
