Structuring C++20 Modules for Clean Code

Modern C++ development has evolved past traditional header files, introducing a powerful module system that reduces build times and improves code isolation. However, transitioning to modules requires a fundamental shift in how you organize files and declare dependencies. This text-based course provides clear, practical guidelines for structuring your C++20 modules to achieve optimal compilation efficiency and maintainable codebases. You will start by understanding the foundational concepts of modules, comparing them to legacy header files, and learning key terminology before moving on to hands-on structural patterns. What you will learn: - Understand the core differences between header inclusion and module importation. - Structure module interface units and implementation units effectively. - Apply best practices for exporting functions, classes, and namespaces. - Configure module partitions to divide large interfaces into manageable pieces. - Manage internal and external dependencies without circular import errors. - Practice modern packaging and compilation techniques compatible with current build systems. The course begins with essential definitions and syntax fundamentals, guides you through organizing single-file and multi-file modules, and concludes with advanced partitioning strategies for large-scale projects. This course is designed for C++ developers who are familiar with basic language syntax and want to modernize their workflow with C++20 features. No prior experience with modules is required.
