wa-socket 0.1.6

Baileys-style WhatsApp Web socket for Python

wa-socket

wa-socket is a Python library that provides a WhatsApp Web socket interface using a Node.js backend powered by the Baileys library.

The goal is to let Python developers interact with WhatsApp Web without writing Node.js code.

---

Features

• WhatsApp Web connection via QR code
• Session persistence (scan once, reconnect automatically)
• Python-first API
• Node.js backend managed automatically
• Suitable for scripts, services, and FastAPI apps

---

Requirements

• Python 3.9+
• Node.js 22+

⚠️ Node.js 20 / 22 are NOT supported
This is due to upstream dependency constraints in Baileys.

Download Node.js 18 LTS from: https://nodejs.org/en/download

Verify installation:

node -v
npm -v


## How it works

`wa-socket` runs a lightweight Node.js process internally.

- Python controls everything
- Node.js is only used for WhatsApp Web (Baileys)
- Communication happens via stdin/stdout (JSON events)
- QR codes are rendered directly in the terminal


## Quick Start

```python
from wa_socket import WhatsAppSocket

sock = WhatsAppSocket(session_id="default")

sock.on_message(lambda msg: print(msg))
sock.start()
sock.wait_for_connection()

sock.send_message("919XXXXXXXXX", "Hello from Python")
