LangChain LangServe Adapter

LangChain is a new and popular framework for building services powered by Large Language Models. It enables applications that are context-aware. It also provides a library called LangServe to create standardized APIs that can be used to interact with LangChain runnables.

This example illustrates how to use nlux to connect to a LangChain runnable made available through LangServe.
