Container class

Pacote:
@azure/cosmos

Operações para ler, substituir ou excluir um contêiner específico existente por ID.

Consulte contêineres para criar novos contêineres e ler/consultar todos os contêineres; use .containers.

Observação: todas essas operações fazem chamadas em relação a um orçamento fixo. Você deve projetar seu sistema de modo que essas chamadas sejam dimensionadas sublinearmente com seu aplicativo. Por exemplo, não chame container(id).read() antes de cada chamada item.read(), para garantir que o contêiner exista; faça isso uma vez na inicialização do aplicativo.

Propriedades

conflicts

Operações para ler e consultar conflitos para o contêiner fornecido.

Para ler ou excluir um conflito específico, use .conflict(id).
database
id
items

Operações para criar novos itens e ler/consultar todos os itens

Para ler, substituir ou excluir um item existente, use .item(id).

exemplo
