Simple LangGraph Studio Example

This is a simple example of using LangGraph Studio with a basic echo graph.

Setup

1. Install the requirements:

pip install -r requirements.txt

2. Run LangGraph Studio:

langgraph dev

3. Open your browser and navigate to http://localhost:3000

Project Structure

• graph.py: Contains the graph definition with a simple echo node
• langgraph.yaml: Configuration file for LangGraph Studio
• requirements.txt: Project dependencies

How it Works

The graph consists of a single node that echoes back any message it receives. The state contains:

• messages: A list of messages
• next: The next node to execute

When you send a message through the Studio interface, it will be processed by the process_message node and echoed back.
