Go Middleware Essentials: Build and Scale Web Applications on AWS

Building robust, secure, and scalable web applications in Go requires a deep understanding of how to handle request lifecycles. Middleware is the secret to writing clean, reusable code that manages authentication, logging, and rate limiting before requests ever reach your core logic. In this text-based course, you will transition from writing basic Go handlers to designing modular, production-ready middleware architectures. You will learn how to secure your endpoints using JWT authentication, manage application state, and prepare your Go services for high-availability deployment on AWS. What you'll learn: - Understand the foundational concepts of Go HTTP handlers, multiplexers, and the middleware pattern. - Build custom middleware for JWT authentication, extraction, and validation to secure protected routes. - Apply modern Go structured logging using the standard library to track incoming requests. - Manage request-scoped data efficiently using the Go context package across middleware chains. - Configure and deploy Go web applications to AWS using scalable containerized or serverless patterns. - Practice writing clean, testable middleware code with step-by-step written exercises and code snippets. The course starts with essential terminology and the core mechanics of HTTP handling in Go. You will then progress through step-by-step written guides to construct, chain, and test custom middleware before exploring strategies for deploying your application to AWS. This course is designed for beginner Go developers and backend enthusiasts who want to master web architecture. No prior experience with AWS or middleware is required, though basic familiarity with Go syntax is helpful. Start reading today to build cleaner, more secure Go applications.
