API First: Building Robust REST APIs
摘要
In an enterprise system, an API is more than a technical detail. It is the public contract of your service and also the first clear plan of what the application will do. When you publish this contract, every team that depends on your service commits to it. Front-end developers, mobile apps, automation scripts, and partner systems all build their work around the shapes and rules you define. They may never see your code, but they trust your API to stay stable for a long time. This makes the API one of the most important documents in the entire project.
