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.

export default () => {
  // LangServe adapter that connects to a demo LangChain Runnable API
  const adapter = useChatAdapter({

  });

  return (
    <AiChat
      adapter={adapter}
