langgraph-cli

1<overview>
2The `langgraph` CLI manages the full lifecycle of LangGraph applications — from scaffolding a new project to deploying it to LangGraph Platform (LangSmith Deployments).
3 
4Key commands:
5- **`langgraph new`** — Scaffold a project from a template
6- **`langgraph dev`** — Run locally with hot reload (no Docker)
7- **`langgraph build`** — Build a Docker image
8- **`langgraph up`** — Launch locally via Docker Compose
9- **`langgraph deploy`** — Ship to LangGraph Platform
10- **`langgraph dockerfile`** — Generate a Dockerfile
11 
12All commands (except `new`) read from a `langgraph.json` config file in the project root.
