Building Serverless Edge Functions with Cloudflare Workers and Wrangler

Traditional server hosting often introduces latency and complex infrastructure management. By running code at the edge with Cloudflare Workers, you can deliver lightning-fast experiences to users globally without managing servers. This text-based course guides you through the entire process of developing, testing, and deploying serverless functions. You will transition from understanding basic edge computing concepts to writing clean, modern JavaScript that runs on a global network. What you'll learn: - Understand the core principles of edge computing and serverless architecture - Configure the Wrangler CLI to manage and deploy your edge projects - Write serverless functions using modern ES modules and JavaScript - Manage environment variables, secrets, and configuration files securely - Test and debug your workers locally before deploying them to production - Explore integration basics with edge storage solutions like KV and D1 databases You will start with key terminology and foundational concepts of edge networks before moving on to practical configuration. Through structured written explanations and step-by-step code examples, you will learn to build, test, and deploy functional edge applications. This course is designed for web developers and beginners curious about serverless technology. No prior experience with Cloudflare or command-line deployment tools is required, though basic familiarity with JavaScript is helpful.
