But if you want to use `async` / `await` without FastAPI, you can do it as well.

### Write your own async code { #write-your-own-async-code }

///

## Writing templates { #writing-templates }

Then you can write a template at `templates/item.html` with, for example:

```jinja hl_lines="7"
{!../../docs_src/templates/templates/item.html!}
```
