# Geração de Projetos - Modelo

Você pode usar um gerador de projetos para começar, por já incluir configurações iniciais, segurança, banco de dados e os primeiros _endpoints_ API já feitos para você.

Um gerador de projetos sempre terá uma pré-configuração que você pode atualizar e adaptar para suas próprias necessidades, mas pode ser um bom ponto de partida para seu projeto.

## Full Stack FastAPI PostgreSQL

The security and dependency injection stuff is written once.

And you can make it as complex as you want. And still, have it written only once, in a single place. With all the flexibility.

But you can have thousands of endpoints (*path operations*) using the same security system.

And all of them (or any portion of them that you want) can take the advantage of re-using these dependencies or any other dependencies you create.

And all of them will use the same WebSocket connection.

## Using `Depends` and others

In WebSocket endpoints you can import from `fastapi` and use:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

They work the same way as for other FastAPI endpoints/*path operations*:

    ```Python hl_lines="68-69  82"

You can use this template to get started, as it includes a lot of the initial set up, security, database and some API endpoints already done for you.
