Note: To see and use how nsflow client works along with neuro-san library, please visit https://github.com/cognizant-ai-lab/neuro-san-studio

nsflow is a react-based developer-oriented client that enables users to explore, visualize, and interact with smart agent networks. It integrates with NeuroSan for intelligent agent-based interactions.

Project Snapshot


Installation & Running nsflow

Prerequisite: install ffmpeg for text-to-speech and speech-to-text support

  • On Mac
brew install ffmpeg
  • On Linux
sudo apt install ffmpeg

nsflow can be installed and run in two different ways:

1️⃣ Run nsflow using pypi package

To simplify execution, nsflow provides a CLI command to start both the backend and frontend simultaneously.

Step 1: Create and source a virtual environment

python -m venv .venv
source .venv/bin/activate

Step 2: Install nsflow from pip

pip install nsflow

Step 3: Run Everything with a Single Command

python -m nsflow.run

By default, this will start:

  • backend (FastAPI + NeuroSan) here: http://127.0.0.1:4173/docs or http://127.0.0.1:4173/redoc
  • frontend (React) here: http://127.0.0.1:4173

2️⃣ Development & Contribution (Manually Start Frontend & Backend)

If you want to contribute, ensure you have the necessary dependencies installed. To start the frontend and backend separately, follow these steps:

Step 1: Clone the Repository

git clone https://github.com/cognizant-ai-lab/nsflow.git
cd nsflow

Step 2: Install Dependencies

  • Make sure you have python (preferably Python 3.12) installed.
    python -m venv .venv
    source .venv/bin/activate
    pip install -r requirements.txt
    pip install -r requirements-dev.txt
    

Step 3: Start the Backend in dev mode & Frontend separately

  • Ensure that you have a few example hocon files in your registries and the same mapped in registries/manifest.

  • [Optional] Ensure that you have the necessary coded tools in the coded_tools dir.

  • From the root start Backend:

    python -m nsflow.run --dev
    
  • Start Frontend:

    • Ensure that you have Node.js (with Yarn) installed.
    • Follow the instructions to setup the frontend here: ./nsflow/frontend/README.md
    • On another terminal window
      cd nsflow/frontend; yarn install
      yarn dev
      
  • By default:

    • backend will be available at: http://127.0.0.1:8005
    • frontend will be available at: http://127.0.0.1:5173
    • You may change the host/port configs using environment variables for fastapi (refer run.py) and using frontend/.env.development for react app

Step 4: To make sure your changes to frontend take effect in the wheel, run the script

  • To build the Frontend
    sh build_scripts/build_frontend.sh
    

Note: The above script's output should show that ./nsflow dir contains a module prebuilt_frontend

  • To build and test the wheel locally
    sh build_scripts/build_wheel.sh
