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

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.
