nikki-python 2.0.3

initial beta version

nikkiServiceBase for Python

Easy-to-use Python client for connecting your service to the nikki.build playground using WebSocket.

---

What this library offers

• Simple async WebSocket connection
• Automatic handling of serviceDef.json + serviceToken.json
• Strict validation at startup (fail-fast with clear errors)
• Auto-reconnect (optional)
• Clean callbacks: onConnect, onConnect, onError, onData
• Two send methods:
  • await client.send(...) → normal send (raises on rate limit)
  • client.send_nowait(...) → safe for callbacks (never crashes, ignores rate limit)
• Full size & rate-limit protection (exactly matches platform rules)
• Production-ready, defensive, and very easy to use

---

Installation

1. Install the only dependency:

pip install websockets

Quick Start

import asyncio
import time
from nikki_python.nikki_client import nikkiServiceBase


async def main():

    client = nikkiServiceBase(auto_reconnect=True)

    def onConnect_handler(details):   print(f"✅ CONNECTED ")
    def onDisconnect_handler(details): print(f"❌ DISCONNECTED → {details}")
    def onError_handler(error):       print(f"⚠️  ERROR → {error}")

    def onData_handler(data: dict):
        print(f"📨 RECEIVED: {data}")

        # inner = data.get("data", {})
        # said = inner.get("said", "")

        # if isinstance(said, str):
        #     has_on = "on" in said.lower()
        #     reply = {"state": has_on}
        #     print(f"   → said = '{said}' | contains 'on' = {has_on} → replying {reply}")

        #     client.send_nowait(reply)          # ← ONE LINE, super clean!


    client.onConnect = onConnect_handler
    client.onDisconnect = onDisconnect_handler
    client.onError = onError_handler
    client.onData = onData_handler

    await client.connect()

    print("📤 Sending 100 test messages (every 2 seconds)...")
    for i in range(100):
        test = {"state" : bool(i %2== 0)}
        try:
            await client.send(test)
            print(f"   Sent #{i+1}/100")
        except Exception as e:
            print(f"   Send failed: {e}")
        await asyncio.sleep(2)

    await asyncio.sleep(30)
    await client.disconnect()
    print("🏁 Test completed.")


if __name__ == "__main__":
    asyncio.run(main())
