Go File I/O and Structs: Build a Wiki Page Reader and Writer

Working with files is a fundamental skill for any developer, yet managing data storage safely can feel daunting at first. This course guides you through the core concepts of Go file input/output (I/O) by building a practical, text-based wiki page manager. You will transition from writing basic scripts to managing persistent data on your local system. Through clear explanations and written coding exercises, you will learn how to structure data with Go structs, serialize information to disk, and retrieve it efficiently using modern Go practices. You will gain hands-on experience using the latest standard library features, bypassing deprecated methods to write clean, production-ready code. What you'll learn: - Understand core Go file I/O concepts and basic data persistence. - Define and utilize Go structs to model wiki page data cleanly. - Write data to text files using modern, non-deprecated standard library functions. - Read and parse text files back into Go structures safely. - Implement robust error handling to prevent application crashes during file operations. - Practice file system operations through step-by-step written coding challenges. The course starts with foundational definitions of Go structs and file system mechanics. You will then progress to writing data, handling errors, and reading files back into memory, wrapping up with a structured project that ties these concepts together. Designed for beginner Go programmers who understand basic syntax and want to learn practical data modeling and file handling. No advanced database or system-level experience is required.
