Foreword What is R What are the problems caused by DI tools? Current Situation Evolution Stage 1 Evolution Stage 2 Evolution Stage 3 Conclusion References Foreword On April 17, 2020, I start a huge project to migrate the Future[T] from legacy playframework project to ZIO. Three months later, after tens of thousands of lines of code modification, the migration was a complete success. In September, I used this experience as the background to share in the Chinese Scala Meetup community with the title “Introduction to ZIO”. In this share, I explained a fanatic imageation, 在这次分享中，我展望了一个美好的愿景，借由 ZIO 的类型参数 R 提供的抽象能力来实现代码的可移植性，和提高可测试性。但想在遗留项目中实现这个愿景并不容易，主要挑战来自遗留项目的代码耦合，和开发者的思维惯性。如今，这个愿景已经达成。我会在这篇 Post 中与你分享我的进化之路。 ...
