JSON Serialization in Go: Mapping Structs and APIs

Working with web APIs in Go requires a solid understanding of how to translate JSON data into structured code. This text-based course guides you through the mechanics of parsing and generating JSON using Go's strong typing system. You will transition from manually parsing raw bytes to confidently designing type-safe Go structs that mirror complex API payloads. You will learn how to handle data type mismatches, work with nested structures, and apply modern Go conventions to ensure clean, robust serialization. What you will learn: 1. Understand the core principles of JSON marshaling and unmarshaling in Go. 2. Design Go structs that align with external API responses using precise struct tags. 3. Handle type mismatches, null values, and optional fields safely using pointers and modern types. 4. Leverage converter tools and structure generator workflows efficiently. 5. Process dynamic or deeply nested JSON payloads with custom marshaling logic. 6. Apply modern Go practices for error handling and validation during data parsing. We begin with foundational concepts, establishing how Go's compiler maps keys to fields. From there, you will read through clear, step-by-step code breakdowns that walk you through increasingly complex data structures and validation techniques. This course is designed for beginner Go developers who want to master data exchange. No advanced Go experience is required, though a basic understanding of variables and functions is helpful.
