NyanCAD server package with marimo integration

NyanCAD Server

NyanCAD Server is a Python package that provides an ASGI server for hosting NyanCAD applications with marimo notebook integration.

Features

• Serves NyanCAD static files (HTML, CSS, JavaScript, assets) at the root path
• Integrates marimo notebook server at /notebook/ endpoint
• Bundles all static assets in the wheel for easy deployment
• Simple command-line interface for starting the server
• Development mode with auto-reload support

Installation

pip install nyancad-server

Usage

Command Line

Start the server with default settings (localhost:8080):

nyancad-server

Custom host and port:

nyancad-server --host 0.0.0.0 --port 3000

Development mode with auto-reload:

nyancad-server --reload

Programmatic Usage

from nyancad_server.server import create_app
import uvicorn

app = create_app()
uvicorn.run(app, host="localhost", port=8080)

Server Endpoints

• / - NyanCAD web interface (static files)
• /css/, /js/, /library/, etc. - Static assets
• /wheels/ - Python wheels (including nyancad package)
• /notebook/ - Marimo notebook interface

Architecture

The server creates a Starlette ASGI application that:

1. Static Files: Serves the entire public/ folder contents at the root path using Starlette's StaticFiles
2. Marimo Integration: Mounts a marimo ASGI app at /notebook/ that hosts the NyanCAD notebook
3. Asset Bundling: All static files and the notebook are bundled into the wheel during package build

This mirrors the existing WASM setup where users can access the main interface at / and the notebook at /notebook/, but replaces the WASM notebook with a full marimo server.

Development

The server includes fallback logic to work in development mode by looking for files relative to the source code when bundled assets are not available.

Requirements

• Python 3.8+

• marimo >= 0.13.0

• uvicorn[standard] >= 0.23.0

• nyancad >= 0.1.0
