npm install react-socket-client

```



Or using pnpm:



```bash

pnpm add react-socket-client

```



## 🚀 Quick Start Guide



### 1. Setting up the SocketProvider



Wrap your application with the `SocketProvider` at the root level:



```jsx

import React from 'react';

import { SocketProvider } from 'react-socket-client';



const SOCKET_URI = 'http://localhost:3000';



export default function App() {

  return (

    

      {/* Your app components */}

    

  );

}

```



### 2. Using SocketProvider with Options



Configure advanced options for your socket connection:



```jsx

import React from 'react';

import { SocketProvider } from 'react-socket-client';



const SOCKET_URI = 'http://localhost:3000';



const socketOptions = {

  reconnection: true,

  reconnectionAttempts: Infinity,

  reconnectionDelay: 1000,

  reconnectionDelayMax: 10000,

  autoConnect: true,

  transports: ['polling', 'websocket'],

  rejectUnauthorized: true

};



export default function App() {

  return (

    

      {/* Your app components */}

    

  );

}

```



### 3. Listening to Socket Events



Listen to socket events using the `Socket` component:



```jsx

import React from 'react';

import { Socket } from 'react-socket-client';



export default function MyComponent() {

  const handleConnect = (data) => {

    console.log('Socket connected', data);

  };

  

  const handleDisconnect = (data) => {

    console.log('Socket disconnected');

  };



  return (

    


      

      

    


  );

}

```



## 🪝 Powerful Utility Hooks



### useSocketEmit



Emit events to the server with type safety:



```jsx

import React from 'react';

import { useSocketEmit } from 'react-socket-client';



export default function ChatInput() {

  const emit = useSocketEmit();

  

  const sendMessage = (message) => {

    emit('chat message', { text: message, timestamp: Date.now() });

  };



  return (

    


       e.key === 'Enter' && sendMessage(e.target.value)} 

      />

       sendMessage(document.querySelector('input').value)}>

        Send

      

    


  );

}

```



### useSocketListener



Listen to socket events with automatic cleanup:



```jsx

import React, { useState } from 'react';

import { useSocketListener } from 'react-socket-client';



export default function MessageList() {

  const [messages, setMessages] = useState([]);

  

  useSocketListener('chat message', (data) => {

    setMessages(prev => [...prev, data]);

  });

  

  useSocketListener('user joined', (data) => {

    console.log(`${data.username} joined the chat`);

  });



  return (

    


      {messages.map((msg, index) => (

        
{msg.text}


      ))}

    


  );

}

```



### useSocketStatus



Monitor connection status in real-time:



```jsx

import React from 'react';

import { useSocketStatus } from 'react-socket-client';



export default function ConnectionIndicator() {

  const { status, error } = useSocketStatus();

  

  const getStatusColor = () => {

    switch(status) {

      case 'connected': return 'green';

      case 'connecting': return 'orange';

      case 'disconnected': return 'red';

      default: return 'gray';

    }

  };

  

  return (

    


      ●

       Status: {status}

      {error && 
Error: {error.message}
}

    


  );

}

```



## 🔄 Enhanced useSocket Hook



The powerful `useSocket` hook provides direct access to the socket instance along with connection status and error information:



```jsx

import React, { useEffect } from 'react';

import { useSocket } from 'react-socket-client';



export default function ChatRoom() {

  const { socket, status, error } = useSocket();

  

  useEffect(() => {

    if (socket) {

      socket.on('connect', handleConnect);

      socket.on('disconnect', handleDisconnect);

      socket.on('chat message', handleIncomingMessage);

    }

    

    // Cleanup listeners on unmount

    return () => {

      if (socket) {

        socket.off('connect', handleConnect);

        socket.off('disconnect', handleDisconnect);

        socket.off('chat message', handleIncomingMessage);

      }

    };

  }, [socket]);

  

  const handleConnect = (data) => {

    console.log('Socket connected', data);

  };

  

  const handleDisconnect = (data) => {

    console.log('Socket disconnected');

  };

  

  const handleIncomingMessage = (data) => {

    console.log('Received message:', data);

  };



  const sendMessage = (message) => {

    if (socket) {

      socket.emit('chat message', { text: message, timestamp: Date.now() });

    }

  };



  return (

    


      


        Connection Status: {status}

        {error &&  Error: {error.message}}

      


       e.key === 'Enter' && sendMessage(e.target.value)} 

      />

       sendMessage(document.querySelector('input').value)}>

        Send Message

      

    


  );

}

```



## 📝 Configurable Logging System



Fine-tune your debugging experience with configurable logging levels and custom logger support:



```jsx

import React from 'react';

import { SocketProvider } from 'react-socket-client';



// Create a custom logger with your preferred formatting

const customLogger = {

  error: (message, ...args) => console.error('[ReactSocket] ERROR:', message, ...args),

  warn: (message, ...args) => console.warn('[ReactSocket] WARN:', message, ...args),

  info: (message, ...args) => console.info('[ReactSocket] INFO:', message, ...args),

  debug: (message, ...args) => console.debug('[ReactSocket] DEBUG:', message, ...args),

};



export default function App() {

  return (

     

      {/* Your app components */}

    

  );

}

```



### Available Log Levels



- `error`: Critical issues that prevent normal operation

- `warn`: Potentially harmful situations

- `info`: General informational messages

- `debug`: Detailed debugging information (recommended for development only)



## 🎯 TypeScript Generic Types Support



Achieve type safety with generic parameters for event data in all components and hooks:



```tsx

import React from 'react';

import { Socket, useSocketListener } from 'react-socket-client';



// Define your custom event data types

interface ChatMessage {

  userId: string;

  username: string;

  message: string;

  timestamp: number;

}



interface UserStatus {

  userId: string;

  status: 'online' | 'offline';

}



export default function ChatComponent() {

  // Type-safe event handler with useSocketListener

  const handleMessage = (data: ChatMessage) => {

    console.log(`Message from ${data.username}: ${data.message}`);

  };

  

  const handleUserStatus = (data: UserStatus) => {

    console.log(`User ${data.userId} is now ${data.status}`);

  };



  return (

    


      

      

    


  );

}

```



### Benefits of TypeScript Support



- ✅ Compile-time type checking

- ✅ Autocomplete in your IDE

- ✅ Reduced runtime errors

- ✅ Better code documentation

- ✅ Easier refactoring



## ⚠️ Comprehensive Error Handling



Robust error handling mechanisms to ensure your application remains stable even during connection issues:



### Global Error Handler



Handle connection errors at the provider level:



```tsx

import React from 'react';

import { SocketProvider } from 'react-socket-client';



export default function App() {

  const handleError = (error: Error) => {

    console.error('Socket connection error:', error);

    // Show user-friendly error message

    // Log to error tracking service

    // Attempt reconnection or fallback

  };

  

  return (

     

      {/* Your app components */}

    

  );

}

```



### Component-Level Error Monitoring



Monitor connection status and errors within your components:



```tsx

import React from 'react';

import { useSocket } from 'react-socket-client';



export default function ConnectionStatus() {

  const { socket, status, error } = useSocket();



  // Display user-friendly connection status

  const renderStatus = () => {

    switch(status) {

      case 'connected':

        return Connected ✓;

      case 'connecting':

        return Connecting...;

      case 'disconnected':

        return Disconnected ✗;

      default:

        return Unknown;

    }

  };



  return (

    


      
Status: {renderStatus()}


      {error && (

        


          Error: {error.message}

           socket?.connect()}>

            Reconnect

          

        


      )}

    


  );

}

```



### Error Recovery Strategies



- Automatic reconnection with exponential backoff

- Graceful degradation during network issues

- User notifications for connection problems

- Fallback mechanisms for critical features
