  This template scaffolds a LangChain.js + Next.js starter app. It showcases how to use and combine LangChain modules for several use cases. Specifically: - [Simple chat](/app/api/chat/route.ts) - [Returning structured output from an LLM call](/app/api/chat/structured_output/route.ts) - [Answering complex, multi-step questions with agents](/app/api/chat/agents/route.ts) - [Retrieval augmented generation (RAG) with a chain and a vector store](/app/api/chat/retrieval/route.ts) - [Retrieval augmented generation (RAG) with an agent and a vector store](/app/api/chat/retrieval_agents/route.ts) Most of them use Vercel's AI SDK to stream tokens to the client and display the incoming messages. The agents use LangGraph.js, LangChain's framework for building agentic workflows.

  This is the official LangChain.js + Next.js starter template, designed for developers building interactive AI applications. It provides a production-ready foundation to quickly implement common AI use cases, including: simple chat, structured output from LLMs, complex multi-step questions with agents, and retrieval augmented generation (RAG) with both chains and agents. It leverages Vercel's AI SDK for streaming and LangGraph.js for robust agentic workflows.
