10 Tips for Cleaner C++ 20 Code
summary
Builds a small VOD app and iteratively refactors it so you can see each change: splits a bulky readMovies into readMovie + lazy generator via C++20 coroutines to avoid loading 10k files, replaces exceptions with TL expected / std expected for expected errors, introduces constructor injection and the header‑only IoC hypodermic to swap a mock streamer (tests shrink from waiting 20s), moves APIs into interfaces, prefers composition over implementation inheritance, and shows modules/head‑units work but tooling is uneven.
