LangGraph Authentication Workflow

Minimal example showing an authentication workflow built with LangGraph, plus a small QA workflow.

Quick start

1. Clone the repo.
2. Create a virtualenv and install dependencies:

python -m venv .venv
source .venv/bin/activate   # or `.venv\Scripts\activate` on Windows
pip install -r requirements.txt
# or the single-line install suggested:
pip install -q langgraph==0.2.57 langchain-ibm==0.3.10

3. Copy .env.example to .env and add your API keys (if you plan to use external LLMs):

cp .env.example .env
# then edit .env and add your keys

4. Run the workflows with the runner:

python runner.py

Notes

• The repository excludes .env and other local files via .gitignore.
• Add your keys locally via .env or environment variables.
