Managing External Dependencies in AWS Lambda with CDK

Deploying serverless functions often requires more than just writing core logic; you need to bundle external libraries efficiently without bloating your deployment package. This text-based course guides you through the exact patterns and best practices for managing Node.js dependencies within AWS Lambda when using the Cloud Development Kit (CDK). You will start with the fundamental concepts of serverless architecture and CDK constructs before moving into practical dependency management. Learn how to optimize your deployment packages, leverage AWS Lambda Layers, and use modern CDK constructs like NodejsFunction for automated bundling. What you'll learn: - Understand the fundamentals of AWS Lambda execution environments and package size limits - Configure the CDK NodejsFunction construct to automatically bundle external dependencies using esbuild - Create and manage AWS Lambda Layers to share common libraries across multiple serverless functions - Exclude development dependencies to keep your deployment artifacts lightweight and fast - Structure your CDK project directory to separate infrastructure code from application logic - Apply modern best practices for testing and verifying local dependencies before deployment This course begins with essential serverless concepts and terminology, guiding you step-by-step through configuration files, construct properties, and real-world deployment workflows. It is designed for developers and cloud beginners who want to build clean, maintainable, and highly optimized serverless infrastructure. No advanced AWS experience is required.
