## 🚀 Getting Started

### Prerequisites

- Python 3.8 or higher
- Go 1.19+ (for building from source)

### Installation

```bash
pip install neonize
```

### Quick Start

```python
from neonize.client import NewClient
from neonize.events import MessageEv, ConnectedEv, event

# Initialize client
client = NewClient("your_bot_name")

@client.event(ConnectedEv)
def on_connected(client: NewClient, event: ConnectedEv):
    print("🎉 Bot connected successfully!")

@client.event(MessageEv)
def on_message(client: NewClient, event: MessageEv):
    if event.message.conversation == "hi":
        client.reply_message("Hello! 👋", event.message)

# Start the bot
client.connect()
event.wait()  # Keep running
```

### Async Version

```python
import asyncio
from neonize.aioze.client import NewAClient
from neonize.aioze.events import MessageEv, ConnectedEv

client = NewAClient("async_bot")

@client.event(MessageEv)
async def on_message(client: NewAClient, event: MessageEv):
    if event.Message.conversation == "ping":
        await client.reply_message("pong! 🏓", event)

async def main():
    await client.connect()
    await client.idle()  # Keep receiving events

asyncio.run(main())
```

!!! important "Python 3.10+ Event Loop"
    Neonize uses `asyncio.run()` as the standard entry point. The event loop is
    automatically obtained via `asyncio.get_running_loop()` inside `connect()`.
    **Do not** use the deprecated `asyncio.get_event_loop()` or
    `loop.run_until_complete()` — these raise errors on Python 3.12+.

## 💡 Examples

### 📱 Basic Client Setup

```python
from neonize.client import NewClient
from neonize.events import MessageEv, ConnectedEv, event
import logging

# Enable logging for debugging
logging.basicConfig(level=logging.INFO)

# Initialize the WhatsApp client
client = NewClient(
    name="my-whatsapp-bot",
    database="./neonize.db"
)

# Handle successful connection
@client.event(ConnectedEv)
def on_connected(client: NewClient, event: ConnectedEv):
    print("🎉 Successfully connected to WhatsApp!")
    print(f"📱 Device: {event.device}")

# Start the client
client.connect()
event.wait()
```

### 💬 Sending Messages

```python
from neonize.utils import build_jid

# Send simple text message
jid = build_jid("1234567890")
client.send_message(jid, text="Hello from Neonize! 🚀")

# Send image with caption
with open("image.jpg", "rb") as f:
    image_data = f.read()

image_msg = client.build_image_message(
    image_data,
    caption="Check out this amazing image! 📸",
    mime_type="image/jpeg"
)
client.send_message(jid, message=image_msg)

# Send document file
with open("document.pdf", "rb") as f:
    doc_data = f.read()

doc_msg = client.build_document_message(
    doc_data,
    filename="document.pdf",
    caption="Here is the document you requested",
    mime_type="application/pdf"
)
client.send_message(jid, message=doc_msg)
```

### 🎭 Message Event Handling

```python
from neonize.events import MessageEv, ReceiptEv, PresenceEv
from datetime import datetime

# Handle incoming text messages
@client.event(MessageEv)
def on_message(client: NewClient, event: MessageEv):
    message_text = event.message.conversation
    sender_jid = event.info.message_source.sender
    chat_jid = event.info.message_source.chat
    
    print(f"📨 Received from {sender_jid}: {message_text}")
    
    # Auto-reply functionality
    if message_text and message_text.lower() == "hello":
        client.send_message(chat_jid, text="Hello there! 👋")
    elif message_text and message_text.lower() == "help":
        help_text = """
🤖 *Bot Commands:*
• hello - Get a greeting
• help - Show this help message
• time - Get current time
• joke - Get a random joke
"""
        client.send_message(chat_jid, text=help_text)
    elif message_text and message_text.lower() == "time":
        current_time = datetime.now().strftime("%Y-%m-%d %H:%M:%S")
        client.send_message(chat_jid, text=f"🕐 Current time: {current_time}")

# Handle message receipts (delivery status)
@client.event(ReceiptEv)
def on_receipt(client: NewClient, event: ReceiptEv):
    print(f"📧 Message {event.receipt.type}: {event.message_ids}")

# Handle typing indicators
@client.event(PresenceEv)
def on_presence(client: NewClient, event: PresenceEv):
    chat = event.message_source.chat
    participant = event.message_source.sender
    print(f"💬 {participant} is {event.presence} in {chat}")
```

### 👥 Group Management

```python
from neonize.utils import build_jid

# Create a new group
participants = [
    build_jid("1234567890"),
    build_jid("0987654321"),
]

group_info = client.create_group(
    "My Awesome Group 🚀",
    participants
)
print(f"🎉 Group created: {group_info.jid}")

# Get group information
group_info = client.get_group_info(group_jid)
print(f"📋 Group Name: {group_info.group_name}")
print(f"📝 Description: {group_info.group_desc}")
print(f"👥 Participants: {len(group_info.participants)}")

# Add participants to group
client.update_group_participants(
    group_jid,
    [user_jid],
    "add"
)

# Remove participants from group
client.update_group_participants(
    group_jid,
    [user_jid],
    "remove"
)

# Update group name
client.update_group_name(
    group_jid,
    "New Group Name 🎯"
)

# Update group description
client.update_group_description(
    group_jid,
    "This is our updated group description"
)
```

### 🔍 Contact & Profile Management

```python
# Get user profile information
profile = client.get_profile_picture(
    user_jid,
    full_resolution=True
)
print(f"👤 Profile picture URL: {profile.url}")
print(f"🆔 Profile ID: {profile.id}")

# Update your own status
client.set_presence("available")
print("✅ Status updated to available")

# Check if contacts are on WhatsApp
contacts = ["1234567890", "0987654321", "1122334455"]
registered_contacts = client.is_on_whatsapp(contacts)

for contact in registered_contacts:
    if contact.is_in:
        print(f"✅ {contact.jid} is on WhatsApp")
    else:
        print(f"❌ {contact.query} is not on WhatsApp")
```

### 📊 Polls & Interactive Messages

## 📖 Documentation

### Core Classes

- **[`NewClient`](neonize/client.py)** - Main synchronous WhatsApp client
- **[`NewAClient`](neonize/aioze/client.py)** - Asynchronous WhatsApp client
- **[Event System](neonize/events.py)** - Event handling and types
- **[Protocol Buffers](neonize/proto/)** - WhatsApp message definitions
- **[Utilities](neonize/utils/)** - Helper functions and enums

### Event System

The event system in Neonize is built around decorators and type-safe events:

```python
# Synchronous event handling
@client.event(MessageEv)
def on_message(client: NewClient, event: MessageEv):
    handle_message(event)

@client.event(ReceiptEv)
def on_receipt(client: NewClient, event: ReceiptEv):
    handle_receipt(event)

# Asynchronous event handling
@async_client.event(MessageEv)
async def on_message(client: NewAClient, event: MessageEv):
    await handle_message_async(event)
```

### Database Support

Neonize supports multiple database backends for storing session data:

```python
# SQLite (default)
client = NewClient("bot_name", database="./app.db")

# PostgreSQL (recommended for production)
client = NewClient("bot_name", database="postgres://user:pass@localhost/dbname")

# In-memory (for testing)
client = NewClient("bot_name", database=":memory:")
```

### Multi-Session Support

Handle multiple WhatsApp accounts simultaneously:

```python
import asyncio
from neonize.aioze.client import ClientFactory, NewAClient
from neonize.aioze.events import MessageEv, ConnectedEv

client_factory = ClientFactory("multisession.db")

# Load existing sessions from database
for device in client_factory.get_all_devices():
    client_factory.new_client(device.JID)

# Pair an ADDITIONAL account into the same database (shows a fresh QR).
# Without new_device=True a jid-less client resumes the FIRST stored
# session instead of pairing a new one.
new_account = client_factory.new_client(uuid="my-second-account", new_device=True)

# Register shared event handlers
@client_factory.event(ConnectedEv)
async def on_connected(client: NewAClient, event: ConnectedEv):
    print(f"⚡ Client connected")

@client_factory.event(MessageEv)
async def on_message(client: NewAClient, event: MessageEv):
    text = event.Message.conversation
    if text == "ping":
        await client.reply_message("pong!", event)

async def main():
    await client_factory.run()      # connect() all clients
    await client_factory.idle_all()  # keep running

asyncio.run(main())
```

## 🗄️ Database Configuration

### SQLite (Default)

Perfect for development and small-scale deployments:

```python
client = NewClient("my_bot", database="./whatsapp.db")
```

### PostgreSQL (Production Recommended)

For high-performance and scalable applications:

```python
# Basic connection
client = NewClient("my_bot", database="postgres://username:password@localhost:5432/dbname")

# With SSL disabled
client = NewClient("my_bot", database="postgres://username:password@localhost:5432/dbname?sslmode=disable")

# With SSL required
client = NewClient("my_bot", database="postgres://username:password@localhost:5432/dbname?sslmode=require")
```

### Connection Pool Settings

For production applications, configure connection pooling:

```python
database_url = "postgres://user:pass@localhost:5432/neonize?pool_min_conns=5&pool_max_conns=20"
client = NewClient("production_bot", database=database_url)
```

## 🚀 Quick Integration

### With FastAPI

```python
from contextlib import asynccontextmanager
from fastapi import FastAPI
from neonize.aioze.client import NewAClient
from neonize.aioze.events import MessageEv
from neonize.utils.jid import build_jid

whatsapp_client = NewAClient("fastapi_bot")

@whatsapp_client.event(MessageEv)
async def on_message(client: NewAClient, event: MessageEv):
    if event.Message.conversation == "/api_status":
        await client.reply_message("API is running! ✅", event)

@asynccontextmanager
async def lifespan(app: FastAPI):
    # connect() automatically picks up the running event loop
    await whatsapp_client.connect()
    yield
    await whatsapp_client.disconnect()

app = FastAPI(lifespan=lifespan)

@app.get("/send-message")
async def send_message(phone: str, message: str):
    jid = build_jid(phone)
    await whatsapp_client.send_message(jid, message)
    return {"status": "sent"}
```

### With Django

```python
# apps.py
from django.apps import AppConfig
from neonize.client import NewClient
import threading

class WhatsAppConfig(AppConfig):
    name = 'whatsapp_integration'
    
    def ready(self):
        self.whatsapp_client = NewClient("django_bot")
        thread = threading.Thread(target=self.whatsapp_client.connect)
        thread.daemon = True
        thread.start()
```

### With Flask

```python
from flask import Flask, request, jsonify
from neonize.client import NewClient
import threading

app = Flask(__name__)
whatsapp_client = NewClient("flask_bot")

@app.route('/webhook', methods=['POST'])
def webhook():
    data = request.json
    phone = data.get('phone')
    message = data.get('message')
    
    if phone and message:
        jid = build_jid(phone)
        whatsapp_client.send_message(jid, text=message)
        return jsonify({"status": "success"})
    
    return jsonify({"status": "error"}), 400

if __name__ == '__main__':
    # Start WhatsApp client in background
    thread = threading.Thread(target=whatsapp_client.connect)
    thread.daemon = True
    thread.start()
    
    app.run(debug=True)
```
