styly-netsync-server 0.7.2

STYLY NetSync Server - Multiplayer framework for Location-Based Entertainment VR/MR experiences

Prepare develop environment

Option A: Use Dev Container (Recommended)

Prerequisites

• VS Code, Docker
• Dev Container extension

Open Dev Container

Click the >< icon in the bottom-left corner of the window.
(Or press Cmd + Shift + P) and select Dev Containers: Reopen in Container.

Option B:

Prerequisites

• Python >=3.11
• uv

Install styly-netsync-server in development mode

pip install -e .

Usage — STYLY NetSync server & CLIs

When you install the package with pip install -e . (editable / development mode), changes to the package's Python source files in your working tree are reflected immediately when you run the commands below — you don't need to reinstall.

# Start STYLY NetSync Server
styly-netsync-server

# Simulate 50 clients
styly-netsync-simulator --clients 50

# Custom server and room
styly-netsync-simulator --server tcp://localhost --room my_room --clients 50

Logging

File output: add --log-dir DIR to write JSON lines to DIR/netsync-server.log (DEBUG level).

# output logs at ./logs directory
styly-netsync-simulator --log-dir logs

Console output: human-friendly text by default. Use --log-json-console for JSON and --log-level-console LEVEL to change the level.

Rotation & retention: default is 10 MB or 7 days, keeping the newest 20 files. Override with --log-rotation / --log-retention (loguru syntax like "10 MB", "1 day", "keep 5 files").

Bridging: stdlib logging is routed to loguru automatically.

REST bridge for client variables

Starting with this version the server launches an embedded FastAPI application that exposes a REST endpoint for pre-seeding and updating per-client Network Variables by deviceId.

• Endpoint: POST /v1/rooms/{roomId}/devices/{deviceId}/client-variables
• Default port: 8800 (override with environment variable NETSYNC_REST_PORT)
• Payload body:

{
  "vars": {
    "name": "Jack",
    "lang": "EN"
  }
}

• Constraints enforced by the bridge:
  • Variable names: 1–64 characters
  • Values: up to 1024 characters
  • Total variables per client: 20 (additional keys return HTTP 409)
• Behavior:
  • If a device has not connected yet, the values are queued in an in-memory preseed store and automatically applied once the server assigns a clientNo.
  • If the device is already connected, the variables are sent immediately through the existing ZeroMQ pathway.
• Typical usage (curl example):

curl -sS -X POST "http://127.0.0.1:8800/v1/rooms/default_room/devices/00000000-0000-0000-0000-000000000000/client-variables" \
  -H "Content-Type: application/json" \
  -d '{"vars":{"name":"Jack","lang":"EN"}}'

The response includes the current mapping status (clientNo or null) and whether each key was queued or applied.
