Initialize FastPusher instance.

Parameters:

• url (str): API server URL
• token (str): Authentication token
• timeout (int): Request timeout in seconds (default: 10)

• debug (bool): Enable debug mode (default: False)

Send message to a single channel.

Parameters:

• channel (str): Channel name/ID
• data (dict): Message data to send

Returns: API response as dictionary

Example:

result = pusher.push("admin", {
    "title": "System Alert",
    "body": "Server maintenance scheduled for tonight."
})

Send message to multiple channels.

Parameters:

• channels (List[str]): List of channel names
• data (dict): Message data to send

Returns: List of results for each channel

Example:

channels = ["admin", "users", "moderators"]
results = pusher.push_bulk(channels, {

    "body": "New features are now available!"
})

for result in results:
    if result["success"]:
        print(f"✅ {result['channel']}: Success")
    else:
        print(f"❌ {result['channel']}: {result['error']}")

Test connection to the API server.

Returns: True if connection is successful, False otherwise

Example:

if pusher.test_connection():
    print("✅ Server is reachable")
else:
    print("❌ Cannot connect to server")

Close the HTTP session. Always call this when finished.
