Go Structs and Interfaces for Web Development

Writing clean, modular, and testable code in modern web development requires a solid grasp of how data is structured and how components interact. Structs and interfaces form the absolute backbone of Go's type system, enabling you to build highly decoupled and scalable applications. This text-based course guides you from the fundamental definitions of custom types to designing flexible APIs and web services. You will learn how to model real-world data, decouple your application layers, and write highly testable code using idiomatic patterns. What you'll learn: - Understand the core concepts of structs, nesting, and custom types in Go - Implement interfaces to decouple your web handlers from database and external service logic - Apply modern Go patterns, including structured logging and basic generics, to write cleaner code - Design robust data models for web APIs using JSON tags and struct validation - Practice writing mock implementations for unit testing using interface substitution - Structure your web application projects using clean, modular architecture principles You will start with foundational syntax, memory layout, and basic type definitions before progressing to advanced composition, interface design patterns, and mock testing. Each concept is reinforced with clear written explanations, structured code snippets, and practical exercises. Designed for developers who want to master Go's unique type system for web development, this course requires no advanced prerequisites. Start reading today to write cleaner, more professional Go code.
