Go Packages and Visibility: Organizing Clean Code

As your Go programs grow, keeping all your code in a single file becomes unmanageable. Learning how to break your application into clean, reusable packages is essential for writing professional, maintainable Go software. This text-based course guides you through the core concepts of Go packaging, visibility rules, and modern dependency management. You will transition from writing single-file scripts to architecting structured Go applications that follow industry best practices. What you'll learn: 1. Understand the foundational concepts of package declaration and code organization in Go. 2. Apply visibility rules using capitalization to control public and private access. 3. Configure custom packages and import them seamlessly across your codebase. 4. Master modern Go modules for robust package and dependency management. 5. Use standard command-line tools to build, format, and test your custom packages. You will start with the basic vocabulary of Go packages, move into access control mechanics, and finish by setting up a multi-package project using modern module standards. This course is designed for beginner Go developers who want to move beyond basic syntax and start building structured, real-world applications. No advanced programming experience is required.
