## Sobre proxies com um prefixo de caminho removido

Tenha em mente que um proxy com prefixo de caminho removido é apenas uma das maneiras de configurá-lo.

Provavelmente, em muitos casos, o padrão será que o proxy não tenha um prefixo de caminho removido.

import org.apache.maven.api.annotations.Nullable;

/**
 * A request to collect the transitive dependencies and to build a dependency graph from them. There are three ways to
 * create a dependency graph. First, only the root dependency can be given. Second, a root dependency and direct
 * dependencies can be specified in which case the specified direct dependencies are merged with the direct dependencies

## About proxies with a stripped path prefix

Keep in mind that a proxy with stripped path prefix is only one of the ways to configure it.

Probably in many cases the default will be that the proxy doesn't have a stripped path prefix.

...so, you are a [team member of FastAPI](./fastapi-people.md#team){.internal-link target=_blank}? Wow, you are so cool! 😎

You can help with everything on [Help FastAPI - Get Help](./help-fastapi.md){.internal-link target=_blank} the same ways as external contributors. But additionally, there are some tasks that only you (as part of the team) can perform.

Here are the general instructions for the tasks you can perform.

Thanks a lot for your help. 🙇

* Keep commits self-contained. Avoid spreading a single change across multiple commits. A single commit should make sense in isolation.

### Testing changes

After making changes, you can test your code in 2 ways:

1. Run tests.
- Run `./gradlew :<subproject>:quickTest` where `<subproject>` is the name of the subproject you've changed. 
- For example: `./gradlew :launcher:quickTest`.

Then it's your turn, you place your order of 2 very fancy burgers for your crush and you. 🍔🍔

The cashier says something to the cook in the kitchen so they know they have to prepare your burgers (even though they are currently preparing the ones for the previous clients).

E sabemos que editores de texto não têm como oferecer muitas funcionalidades (como sugestões automáticas) para objetos do tipo `dict`, por que não há como eles saberem o tipo das chaves e dos valores.

Podemos fazer melhor...

## O que caracteriza uma dependência

Até agora você apenas viu dependências declaradas como funções.

Você também poderia utilizar `from starlette.responses import HTMLResponse`.

O **FastAPI** fornece as mesmas `starlette.responses` como `fastapi.responses` apenas como um facilitador para você, desenvolvedor. Mas a maior parte das respostas vem diretamente do Starlette.

   * The problem with these is that remove(K, long) has to be done in two phases by definition ---
   * first decrementing to zero, and then removing. putIfAbsent or replace could observe the
   * intermediate zero-state. Ways we could deal with this are:
   *
   * - Don't define any of the ConcurrentMap operations. This is the current state of affairs.
   *
   * - Define putIfAbsent and replace as treating zero and absent identically (as currently

```json
{"message": "Hello World"}
```

...this response will return:

```json
{
  "message": "Hello World"
}
```

Of course, you will probably find much better ways to take advantage of this than formatting JSON. 😉

## Default response class

When creating a **FastAPI** class instance or an `APIRouter` you can specify which response class to use by default.
