### 編寫自己的非同步程式碼

Starlette （和 **FastAPI**） 是基於 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a> 實作的，這使得它們與 Python 標準函式庫相容 <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>。
