Intermediate TypeScript: Working with Native ES Modules

Modern web development relies heavily on modular code, but navigating the shift from legacy module formats to modern standards can be challenging. This course clarifies how TypeScript handles module resolution in modern environments, enabling you to write clean, future-proof code. You will transition from basic syntax to understanding how your compiled code behaves in real-world environments. By completing this course, you will gain a deep understanding of how TypeScript interacts with native ECMAScript Modules (ESM) and CommonJS (CJS). You will learn to configure your project settings to support modern module resolution, handle mixed-module environments, and use modern TypeScript features like type-only imports and exports. What you'll learn: - Understand the core differences between CommonJS and native ES Modules in TypeScript - Configure package settings and compiler options to target modern module systems - Manage file extensions like .mts, .cts, .js, and .mjs correctly in your projects - Implement type-only imports and exports to optimize your compiled JavaScript output - Resolve common module loading errors and interoperability issues in Node.js and browser environments - Apply modern TypeScript configurations to ensure smooth dependency resolution This course begins with foundational concepts, defining key terminology and explaining the history of JavaScript modules before diving into configuration files and compiler options. You will then explore practical scenarios, focusing on how to structure your imports and exports for modern runtime environments. This course is designed for intermediate TypeScript developers who want to deepen their understanding of module resolution and modern build configurations. No advanced setup is required, but a basic familiarity with TypeScript and Node.js is recommended. Start writing cleaner, modern modular TypeScript code today.
