A starter template scaffolding a LangChain.js application in Next.js, with example API routes for chat, structured output, agents, and RAG. It uses LangGraph.js for agentic workflows and the Vercel AI SDK to stream tokens to the client.

Use cases

• build a chatbot with nextjs and langchain
• streaming llm chat app starter
• rag with vector store in nextjs
• llm agent example with langgraph
• structured output from llm calls
• deploy langchain app to vercel

When to choose

• you want a ready-made Next.js + LangChain.js starting point with working chat, RAG, and agent examples
• you want serverless-friendly, Vercel-deployable LLM streaming UI
• you want to learn LangGraph.js agent patterns with minimal boilerplate

When to avoid

• you need a production backend framework rather than a demo scaffold
• you don't use Next.js or the JavaScript/TypeScript ecosystem
• you need non-OpenAI model setup out of the box without changes
