### `Query` as the default value or in `Annotated` { #query-as-the-default-value-or-in-annotated }

Keep in mind that when using `Query` inside of `Annotated` you cannot use the `default` parameter for `Query`.

Instead, use the actual default value of the function parameter. Otherwise, it would be inconsistent.

You can "star" FastAPI in GitHub (clicking the star button at the top right): [https://github.com/fastapi/fastapi](https://github.com/fastapi/fastapi). ⭐️

By adding a star, other users will be able to find it more easily and see that it has been already useful for others.

# Deployments Concepts { #deployments-concepts }

When deploying a **FastAPI** application, or actually, any type of web API, there are several concepts that you probably care about, and using them you can find the **most appropriate** way to **deploy your application**.

Some of the important concepts are:

* Security - HTTPS
* Running on startup
* Restarts
* Replication (the number of processes running)
* Memory
* Previous steps before starting

### When Things are Difficult

When things are great, everything is easier, so that doesn't need much instructions. But when things are difficult, here are some guidelines.

        $(document).on('input', '.filter-search-input', function() {
            var query = $(this).val().toLowerCase();
            $(this).closest('.filter-dropdown-menu').find('.filter-check-item').each(function() {
                var label = $(this).find('.filter-check-label').text().toLowerCase();
                $(this).toggle(label.indexOf(query) !== -1);
            });
        });

        // Filter clear group handler

```

This way, when you type `python` in the terminal, the system will find the Python program in `C:\opt\custompython\bin` (the last directory) and use that one.

////

So, if you type:

<div class="termy">

```console
$ python
```

</div>

//// tab | Linux, macOS

The system will **find** the `python` program in `/opt/custompython/bin` and run it.

## Available responses { #available-responses }

Here are some of the available responses.

Keep in mind that you can use `Response` to return anything else, or even create a custom sub-class.

/// note | Technical Details

You could also use `from starlette.responses import HTMLResponse`.

I will show you some of the main concepts you should probably keep in mind when deploying a **FastAPI** application (although most of it applies to any other type of web application).
