### Dependency Injection { #dependency-injection }

FastAPI includes an extremely easy to use, but extremely powerful <dfn title='also known as "components", "resources", "services", "providers"'><strong>Dependency Injection</strong></dfn> system.

* Even dependencies can have dependencies, creating a hierarchy or **"graph" of dependencies**.
* All **automatically handled** by the framework.

    to change, and the implementation is incomplete. This is a big new API we
    are eager for feedback.

 *  New: Support ALPN via Google Play Services' Dynamic Security Provider. This
    expands HTTP/2 support to older Android devices that have Google Play
    Services.
 *  New: Consider all routes when looking for candidate coalesced connections.
    This increases the likelihood that HTTP/2 connections will be shared.

A documentação da API usa **Swagger UI** e **ReDoc**, e cada um deles precisa de alguns arquivos JavaScript e CSS.

Por padrão, esses arquivos são fornecidos por um <abbr title="Content Delivery Network - Rede de Entrega de Conteúdo: Um serviço, normalmente composto por vários servidores, que fornece arquivos estáticos, como JavaScript e CSS. É comumente usado para servir esses arquivos a partir do servidor mais próximo do cliente, melhorando o desempenho.">CDN</abbr>.

# Settings and Environment Variables { #settings-and-environment-variables }

In many cases your application could need some external settings or configurations, for example secret keys, database credentials, credentials for email services, etc.

Most of these settings are variable (can change), like database URLs. And many could be sensitive, like secrets.

For this reason it's common to provide them in environment variables that are read by the application.
