# Bigger Applications - Multiple Files { #bigger-applications-multiple-files }

If you are building an application or a web API, it's rarely the case that you can put everything in a single file.

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

/// info

If you come from Flask, this would be the equivalent of Flask's Blueprints.

## An example file structure { #an-example-file-structure }

   * structures.
   *
   * We make such subtle calls in [okhttp3.internal.ws.MessageInflater] because we try to read a
   * compressed stream that is terminated in a web socket frame even though the DEFLATE stream is
   * not terminated.
   *
   * Use this method to create a degenerate Okio Buffer where each byte is in a separate segment of
   * the internal list.

/// tip | Consejo

Ten en cuenta que los custom proprietary headers se pueden añadir <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">usando el prefijo 'X-'</a>.

Você pode combinar *operações de rota* normais do FastAPI com GraphQL na mesma aplicação.

/// tip | Dica

**GraphQL** resolve alguns casos de uso muito específicos.

Ele tem **vantagens** e **desvantagens** quando comparado a **web APIs** comuns.

Certifique-se de avaliar se os **benefícios** para o seu caso de uso compensam as **desvantagens**. 🤓

**GraphQL** löst einige sehr spezifische Anwendungsfälle.

Es hat **Vorteile** und **Nachteile** im Vergleich zu gängigen **Web-APIs**.

Wiegen Sie ab, ob die **Vorteile** für Ihren Anwendungsfall die **Nachteile** ausgleichen. 🤓
