也就是说，**FastAPI** 针对差不多 80% 的 Python 开发者使用的编辑器进行了测试，而且其它大多数编辑器的工作方式也与之类似，因此，**FastAPI** 的优势几乎能在所有编辑器上体现。

通过这种方式，我就能找到尽可能减少代码重复的最佳方式，进而实现处处都有自动补全、类型提示与错误检查等支持。

所有这些都是为了给开发者提供最佳的开发体验。

## 需求项

经过测试多种备选方案，我最终决定使用  <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">**Pydantic**</a>，并充分利用它的优势。
