goxlrutil-api 0.0.2

Async Python library for communicating with the GoXLR Utility daemon

goxlrutil-api

Async Python library for communicating with the GoXLR Utility daemon.

Features

• Three transports: Unix socket, HTTP, WebSocket
• Async-first with optional sync wrappers
• Live state cache: incoming JSON Patch events are applied automatically
• Typed API: dataclass/enum models for all commands and responses

Installation

pip install goxlrutil-api
# With demo webapp extras:
pip install "goxlrutil-api[webapp]"

Quick start

import asyncio
from goxlrutil_api import GoXLRClient
from goxlrutil_api.transport import UnixSocketTransport

async def main():
    transport = UnixSocketTransport()
    async with GoXLRClient(transport) as client:
        status = await client.get_status()
        for serial, mixer in status.mixers.items():
            print(serial, mixer.hardware.device_type)

asyncio.run(main())

Transports

Class	Usage
UnixSocketTransport	Local daemon via /tmp/goxlr.socket
HttpTransport	HTTP POST /api/command (local or remote)
WebSocketTransport	WebSocket /api/websocket – also receives live Patch events

Demo webapp

# With Poetry (development):
poetry install --all-extras
poetry run uvicorn apps.demo_webapp.main:app --reload

# Or with pip:
pip install "goxlrutil-api[webapp]"
uvicorn apps.demo_webapp.main:app --reload

Open http://localhost:8000

By default the webapp connects via WebSocket (ws://localhost:14564/api/websocket), which enables live patch events – including button presses, volume changes, and fader updates.

To force Unix socket instead (no live events, request/response only):

GOXLR_USE_WS=0 poetry run uvicorn apps.demo_webapp.main:app --reload

The app starts even if the GoXLR daemon is not running – it will show a "not connected" status.

Development

poetry install
poetry run pytest
poetry run ruff check src
poetry run pyright

Protocol notes

• Unix socket uses a 4-byte big-endian length-prefixed JSON frame.
• HTTP sends the same DaemonRequest JSON to POST /api/command.
• WebSocket wraps requests in {"id": <uint>, "data": <DaemonRequest>}.
• State updates from WebSocket are RFC 6902 JSON Patch operations.
