* API keys in:
    * Headers.
    * Query parameters.
    * Cookies, etc.

Plus all the security features from Starlette (including **session cookies**).

All built as reusable tools and components that are easy to integrate with your systems, data stores, relational and NoSQL databases, etc.

### Dependency Injection

* Chaves de API em:
    * Headers.
    * parâmetros da Query.
    * Cookies etc.

Além disso, todos os recursos de seguranças do Starlette (incluindo **cookies de sessão**).

Tudo construído como ferramentas e componentes reutilizáveis que são fáceis de integrar com seus sistemas, armazenamento de dados, banco de dados relacionais e não-relacionais etc.

### Injeção de dependência

      #      tlsSettings:
      #        mode: DISABLE # DISABLE, SIMPLE, MUTUAL, ISTIO_MUTUAL
      #        clientCertificate: # example: /etc/istio/tracer/cert-chain.pem
      #        privateKey:        # example: /etc/istio/tracer/key.pem
      #        caCertificates:    # example: /etc/istio/tracer/root-cert.pem
      #        sni:               # example: tracer.somedomain
      #        subjectAltNames: []

      #        clientCertificate: # example: /etc/istio/tracer/cert-chain.pem

Voici un petit bout de cette histoire.

## Alternatives

Je crée des API avec des exigences complexes depuis plusieurs années (Machine Learning, systèmes distribués, jobs asynchrones, bases de données NoSQL, etc), en dirigeant plusieurs équipes de développeurs.

Dans ce cadre, j'ai dû étudier, tester et utiliser de nombreuses alternatives.

L'histoire de **FastAPI** est en grande partie l'histoire de ses prédécesseurs.

## **FastAPI** compatibility

The simplicity of the dependency injection system makes **FastAPI** compatible with:

* all the relational databases
* NoSQL databases
* external packages
* external APIs
* authentication and authorization systems
* API usage monitoring systems
* response data injection systems
* etc.

## Simple and Powerful

* Clés d'API dans:
    * Le header.
    * Les paramètres de requêtes.
    * Les cookies, etc.

Plus toutes les fonctionnalités de sécurités venant de Starlette (incluant les **cookies de sessions**).

Le tout conçu en composant réutilisable facilement intégrable à vos systèmes, data stores, base de données relationnelle ou NoSQL, etc.
