Serverless Express APIs with AWS Lambda

Transitioning traditional Express.js applications to a serverless environment can seem daunting, but it offers incredible scalability and cost savings. This text-based course guides you through the foundational concepts and practical steps of running Express APIs on AWS Lambda. You will learn how to bridge the gap between traditional Node.js routing and serverless event-driven architecture, enabling you to deploy highly scalable web applications without managing servers. What you'll learn: - Understand serverless architecture fundamentals and how AWS Lambda executes code - Adapt existing Express.js routing to work seamlessly inside a Lambda handler - Configure API Gateway to route incoming HTTP requests to your serverless function - Manage environment variables and secure your database connections in a serverless environment - Optimize performance using modern Node.js features and minimize cold start latency - Troubleshoot common deployment errors and debug serverless Express APIs using CloudWatch logs You will start with the essential terminology of serverless computing before moving into step-by-step code adaptations and deployment configurations. Through clear written explanations and structured code snippets, you will build a solid mental model of serverless Express routing. This course is designed for beginner to intermediate Node.js developers who want to learn serverless deployment, with no prior AWS experience required.
