How to make subflow return stream message

[thfylsty]

I am trying to figure out how to make a subflow return stream messages. My goal is to have the parent flow select different subflows based on a task router, and then stream the subflow results back to the chat output node within the parent flow.

Can anyone provide guidance or examples on how to achieve this?(∩_∩)

Hey @thfylsty! I'm here to help you with any bugs, questions, or contributions. Let's tackle this together!

To make a subflow return stream messages in Langflow, you can follow these steps:

1. Use the SubFlowComponent: This component allows you to integrate subflows within a parent flow. It dynamically executes the subflow and processes its outputs.

2. Enable Streaming: Ensure that the nodes within your subflow that generate messages (e.g., OpenAIModel) have streaming enabled. Set the stream field to true to allow for streaming responses.

3. Connect to Chat Output: In your parent flow, connect the output of the subflow to the ChatOutput node. This will allow the streamed messages from the subflow to be displayed in the chat output.

4. Task Router: Use a task router like DataConditionalRouterComponent to select different subflows based on conditions. This component can route data to different subflows based on specified criteria.

By setting up your flows this way, you can have the parent flow dynamically select and execute subflows, streaming their results back to the chat output node.

If you need more detailed examples or code snippets, let me know!

I am facing difficulty in making my work flow as sub component. is there any documentation available on how to implement it?
