# LangGraph Reflection & Rewriting Demo

This project demonstrates a simple LangGraph state machine that includes:
- **Reflection node** – logs the current state.
- **Rewriting node** – transforms the input string to uppercase.
- **End node** – logs the final state.

## Setup

```bash
npm install
npm run build
npm start
```

The output will show the state at each node and the final transformed result.

## Project Structure

- `src/langgraph.ts` – Defines the state type, node functions, and constructs the graph.
- `src/index.ts` – Entry point that runs the graph with an example input.
- `package.json` – Project metadata and dependencies.
- `tsconfig.json` – TypeScript compiler configuration.

No JavaScript files are present; the entire project is written in TypeScript.
