How to store the streamed response?

[ravi160822]

I want to have streaming enabled, and keep returning the streamed characters one by one in fastapi, and as soon as the entire response is returned, I want to store the response in a db.

Currently I am facing issues with returning the streamed response with fastapi.

I am able to do it with the openai chat completion api, but how do I do this with the langchain streaming?
