# Stream de JSON Lines { #stream-json-lines }

Você pode ter uma sequência de dados que deseja enviar em um "**Stream**"; é possível fazer isso com **JSON Lines**.

/// info | Informação

Adicionado no FastAPI 0.134.0.

## O que é um Stream? { #what-is-a-stream }

"**Streaming**" de dados significa que sua aplicação começará a enviar itens ao cliente sem esperar que toda a sequência esteja pronta.
