🚀 Installation

🎯 Quick Start

1. Wrap your app with the TransmitProvider:

import { TransmitProvider } from 'react-adonis-transmit'

function App() {
  return (
    <TransmitProvider 
      baseUrl="http://your-api-url"
      // Optional: Add auth header
      authHeader="Bearer your-token-here"
      // Optional: Handle messages globally
      onMessage={(channel, event) => {
        console.log(`Message from ${channel}:`, event)
      }}
      // Optional: Enable debug logging
      enableLogging={true}
    >
      {/* Your app components */}
    </TransmitProvider>
  )
}

2. Subscribe to channels with our simple hook:

import { useTransmit } from 'react-adonis-transmit'

function MyComponent() {
  const { subscribe } = useTransmit()

  useEffect(() => {
    // Subscribe to real-time updates
    const unsubscribe = subscribe('my-channel', (event) => {
      console.log('Received event:', event)
    })

    // Auto-cleanup on unmount
    return () => unsubscribe()
  }, [])

  return <div>My Component</div>
}
