### `fastapi dev` with path { #fastapi-dev-with-path }

You can also pass the file path to the `fastapi dev` command, and it will guess the FastAPI app object to use:

```console
$ fastapi dev main.py
```

But you would have to remember to pass the correct path every time you call the `fastapi` command.

In our code example above, we don't use it directly, but we pass it to FastAPI for it to use it.

The `lifespan` parameter of the `FastAPI` app takes an **async context manager**, so we can pass our new `lifespan` async context manager to it.
