@dawn-ai/langchain

LangChain backend adapters for Dawn, the TypeScript meta-framework for LangGraph that lets you build LangGraph agents like Next.js apps. Dawn uses this package to materialize chain routes and provider-aware agent routes — handling tool conversion, streaming, and retry.

agent() materialization resolves a LangChain chat model from the route descriptor. Dawn includes @langchain/openai for the default/backcompat path and lazy-loads optional provider packages when an agent selects or infers another provider.
