It was created to generate the HTML in the backend, not to create APIs used by a modern frontend (like React, Vue.js and Angular) or by other systems (like <abbr title="Internet of Things">IoT</abbr> devices) communicating with it.

Foi criado para gerar HTML no _backend_, não para criar APIs utilizando um _frontend_ moderno (como React, Vue.js e Angular) ou por outros sistemas (como dispositivos <abbr title="Internet das Coisas">IoT</abbr>) comunicando com ele.

## About third party integrations

In this example we are using the OAuth2 "password" flow.

This is appropriate when we are logging in to our own application, probably with our own frontend.

Because we can trust it to receive the `username` and `password`, as we control it.

## Über Integrationen von Drittanbietern

In diesem Beispiel verwenden wir den OAuth2-Flow „Password“.

Das ist angemessen, wenn wir uns bei unserer eigenen Anwendung anmelden, wahrscheinlich mit unserem eigenen Frontend.

Weil wir darauf vertrauen können, dass es den `username` und das `password` erhält, welche wir kontrollieren.

Es wurde erstellt, um den HTML-Code im Backend zu generieren, nicht um APIs zu erstellen, die von einem modernen Frontend (wie React, Vue.js und Angular) oder von anderen Systemen (wie <abbr title="Internet of Things">IoT</abbr>-Geräten) verwendet werden, um mit ihm zu kommunizieren.

Sie würden also **mehrere Container** mit unterschiedlichen Dingen ausführen, wie einer Datenbank, einer Python-Anwendung, einem Webserver mit einer React-Frontend-Anwendung, und diese über ihr internes Netzwerk miteinander verbinden.

In alle Containerverwaltungssysteme (wie Docker oder Kubernetes) sind diese Netzwerkfunktionen integriert.

## Container und Prozesse

So, you would run **multiple containers** with different things, like a database, a Python application, a web server with a React frontend application, and connect them together via their internal network.

All the container management systems (like Docker or Kubernetes) have these networking features integrated into them.

## Containers and Processes

Então, você rodaria **vários contêineres** com coisas diferentes, como um banco de dados, uma aplicação Python, um servidor web com uma aplicação frontend React, e conectá-los juntos via sua rede interna.

Todos os sistemas de gerenciamento de contêineres (como Docker ou Kubernetes) possuem essas funcionalidades de rede integradas a eles.

## Contêineres e Processos

Later, for your production application, you might want to use a database server like **PostgreSQL**.

!!! tip
    There is an official project generator with **FastAPI** and **PostgreSQL**, all based on **Docker**, including a frontend and more tools: <a href="https://github.com/tiangolo/full-stack-fastapi-postgresql" class="external-link" target="_blank">https://github.com/tiangolo/full-stack-fastapi-postgresql</a>
