Modular Node.js Development with CommonJS

Writing all your backend code in a single file quickly becomes unmanageable as your application grows. This text-only course guides you through the foundational concepts of modular architecture in Node.js using the robust CommonJS pattern. You will transition from writing monolithic scripts to designing clean, maintainable, and reusable module structures that make your codebase easy to test, debug, and scale. What you'll learn: - Understand the core mechanics of the Node.js module system and require caching - Design clean module boundaries by separating concerns into independent files - Export and import functions, classes, and objects using CommonJS exports and module.exports - Manage dependencies effectively using package.json and modern packaging practices - Implement safe module patterns to prevent global scope pollution and circular dependencies - Explore interop patterns between CommonJS and modern ES Modules The course starts with fundamental concepts of modularity and module loading, then advances to practical structural patterns, directory organization, and modern integration strategies. It is designed specifically for beginners with basic JavaScript knowledge who want to build structured backend applications, with no prior Node.js architecture experience required.
