Working with JSON in Go: A Practical Guide to Serialization

Exchanging data between applications is a core requirement of modern software development, and JSON is the universal language of the web. This text-based course guides you through mastering Go's standard library to read and write JSON data efficiently. You will transition from struggling with unstructured data to confidently mapping JSON to Go types. Through clear explanations and practical code examples, you will learn how to serialize and deserialize data, manage custom formats, and handle real-world API payloads. What you'll learn: Understand the foundational concepts of JSON syntax and Go's type system compatibility; Encode Go structs, maps, and slices into clean JSON strings and files; Decode complex JSON payloads into structured Go variables using standard library packages; Apply struct tags, including omitempty and custom field names, to control serialization behavior; Implement stream-based encoding and decoding for large files and network connections; Handle dynamic or unknown JSON schemas using empty interfaces and type assertions. The course starts with basic terminology and foundational concepts, then moves progressively into advanced serialization techniques and stream processing. You will work through written explanations and code snippets designed to reinforce your learning. This course is designed for beginner Go developers who want to build a solid foundation in backend data handling. No prior experience with JSON is required, though a basic familiarity with Go syntax is recommended. Start reading today to unlock the full potential of data serialization in Go.
