AWS CloudFront Functions for Front-End Developers

Front-end developers often need to manipulate web requests and responses without the overhead of managing complex backend servers. AWS CloudFront Functions offer a lightning-fast, cost-effective way to run lightweight JavaScript code at the edge, closer to your users. This text-based course guides you through the fundamentals of edge computing, helping you understand how to intercept and modify HTTP requests and responses. You will learn how to write, test, and deploy highly performant edge functions using the specific JavaScript runtime supported by CloudFront. What you'll learn: - Understand the core concepts of edge computing and how CloudFront Functions differ from other serverless options. - Write clean JavaScript code within the constraints of the CloudFront Functions restricted runtime environment. - Manipulate HTTP headers to enhance security, manage cookies, and control caching behavior. - Implement URL rewrites and redirects to dynamically route user traffic or swap assets. - Test and debug your edge functions using built-in AWS tooling before deploying them to production. - Apply modern web security best practices, such as injecting security headers at the edge. The course starts with essential edge networking terminology and runtime limitations before moving into practical scripting scenarios. You will progress through guided written examples, learning how to handle real-world front-end routing and content manipulation challenges. This course is designed for front-end developers, web engineers, and cloud beginners who want to optimize content delivery. No prior AWS experience is required, though a basic understanding of JavaScript and HTTP requests is helpful.
