Why together · 01
Why this combo works.
LangGraph's Python SDK is more mature than the JS version. LangSmith integration for tracing. State persistence via Postgres or other backends.
Setup
pip install langgraph, define your StateGraph, add checkpointer, expose via FastAPI.
Gotchas
- Async Python adds complexity
- Checkpointing storage choice matters at scale
- Tool execution lives in the graph — separate concerns carefully
- Streaming requires SSE or WebSockets
