（和 **FastAPI**） 是基于 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a> 实现的，这使得它们可以兼容 Python 的标准库 <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> 和 <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>。

特别是，你可以直接使用 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a> 来处理高级的并发用例，这些用例需要在自己的代码中使用更高级的模式。...

## OpenAPI 客户端生成

有许多工具可以从**OpenAPI**生成客户端。

一个常见的工具是 <a href="https://openapi-generator.tech/" class="external-link" target="_blank">OpenAPI Generator</a>。

如果您正在开发**前端**，一个非常有趣的替代方案是 <a href="https://github.com/hey-api/openapi-ts" class="external-link" target="_blank">openapi-ts</a>。

## 生成一个 TypeScript 前端客户端

让我们从一个简单的 FastAPI 应用开始：
