A este punto, ya está claro que **FastAPI** con sus ideas está siendo útil para muchas personas.

Está siendo elegido sobre alternativas anteriores por adaptarse mejor a muchos casos de uso.

Muchos desarrolladores y equipos ya dependen de **FastAPI** para sus proyectos (incluyéndome a mí y a mi equipo).

# JSON with Bytes as Base64 { #json-with-bytes-as-base64 }

If your app needs to receive and send JSON data, but you need to include binary data in it, you can encode it as base64.

## Base64 vs Files { #base64-vs-files }

Consider first if you can use [Request Files](../tutorial/request-files.md) for uploading binary data and [Custom Response - FileResponse](./custom-response.md#fileresponse--fileresponse-) for sending binary data, instead of encoding it in JSON.
