Panduan Memulai Cepat WebSocket Solana

Panduan Memulai Cepat

Get Your API Key

Dapatkan kunci API Helius Anda dari dasbor. Anda memerlukannya untuk autentikasi. Agen dapat memperoleh kunci menggunakan Helius CLI.

Choose Your Network

Pilih titik akhir yang sesuai:

Mainnet: wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY
Mainnet (Gatekeeper Beta): wss://beta.helius-rpc.com/?api-key=YOUR_API_KEY
Devnet: wss://devnet.helius-rpc.com/?api-key=YOUR_API_KEY

Create Your First Connection

const ws = new WebSocket('wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY');

ws.onopen = () => {
  console.log('Connected to Solana!');
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  console.log('Received:', data);
};

Subscribe to Updates

// Subscribe to account changes
const subscribeMessage = {
  "jsonrpc": "2.0",
  "id": 1,
  "method": "accountSubscribe",
  "params": [
    "ACCOUNT_ADDRESS_HERE",
    { "commitment": "confirmed" }
  ]
};

ws.send(JSON.stringify(subscribeMessage));

Metode Langganan

Pemantauan Akun

Pantau akun tertentu untuk mengetahui perubahan saldo, pembaruan data, atau transfer kepemilikan.

const ws = new WebSocket('wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY');

const subscribeToAccount = (accountAddress) => {
  const request = {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "accountSubscribe",
    "params": [
      accountAddress,
      {
        "encoding": "jsonParsed",
        "commitment": "confirmed"
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "accountNotification") {
    console.log("Account updated:", data.params.result.value);
    
    // Handle the account change
    const accountInfo = data.params.result.value;
    console.log(`New balance: ${accountInfo.lamports} lamports`);
  }
};

// Subscribe to a wallet address
subscribeToAccount("9PejEmViKHgUkVFWN57cNEZnFS4Qo6SzsLj5UPAXfDTF");

const ws = new WebSocket('wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY');

// Monitor a token account for balance changes
const monitorTokenAccount = (tokenAccountAddress) => {
  const request = {
    "jsonrpc": "2.0",
    "id": 2,
    "method": "accountSubscribe",
    "params": [
      tokenAccountAddress,
      {
        "encoding": "jsonParsed",
        "commitment": "confirmed"
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "accountNotification") {
    const accountData = data.params.result.value.data;
    
    if (accountData.program === "spl-token") {
      const parsed = accountData.parsed;
      console.log(`Token balance: ${parsed.info.tokenAmount.uiAmount}`);
      console.log(`Owner: ${parsed.info.owner}`);
    }
  }
};

Pemantauan Aktivitas Program

Pantau semua akun yang dimiliki oleh suatu program—cocok untuk memantau perdagangan DEX, transfer NFT, atau aktivitas DeFi.

// Monitor Raydium AMM for all trade activity
const RAYDIUM_AMM_PROGRAM = "675kPX9MHTjS2zt1qfr1NYHuzeLXfQM9H24wFSUt1Mp8";

const subscribeToProgram = (programId) => {
  const request = {
    "jsonrpc": "2.0",
    "id": 3,
    "method": "programSubscribe",
    "params": [
      programId,
      {
        "encoding": "jsonParsed",
        "commitment": "confirmed",
        "filters": [
          {
            "dataSize": 752 // Raydium pool account size
          }
        ]
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "programNotification") {
    console.log("Raydium pool updated:", data.params.result.value.pubkey);
    // Process the pool data change
    const accountData = data.params.result.value.account;
    // Parse and handle the pool state change
  }
};

subscribeToProgram(RAYDIUM_AMM_PROGRAM);

// Monitor Magic Eden program for NFT activity
const MAGIC_EDEN_PROGRAM = "M2mx93ekt1fmXSVkTrUL9xVFHkmME8HTUi5Cyc5aF7K";

const subscribeToNFTActivity = () => {
  const request = {
    "jsonrpc": "2.0",
    "id": 4,
    "method": "programSubscribe",
    "params": [
      MAGIC_EDEN_PROGRAM,
      {
        "encoding": "base64",
        "commitment": "confirmed"
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "programNotification") {
    console.log("NFT marketplace activity detected");
    // Decode and process the marketplace instruction
    const accountInfo = data.params.result.value;
    // Handle NFT listing, purchase, or cancellation
  }
};

Pemantauan Transaksi

Lacak transaksi tertentu atau pantau transaksi yang menyebutkan akun tertentu.

// Monitor a specific transaction signature
const trackTransaction = (signature) => {
  const request = {
    "jsonrpc": "2.0",
    "id": 5,
    "method": "signatureSubscribe",
    "params": [
      signature,
      {
        "commitment": "confirmed"
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "signatureNotification") {
    const result = data.params.result;
    
    if (result.value.err) {
      console.log("Transaction failed:", result.value.err);
    } else {
      console.log("Transaction confirmed successfully!");
    }
    
    // Subscription automatically ends after notification
  }
};

// Track a payment or swap transaction
trackTransaction("YOUR_TRANSACTION_SIGNATURE_HERE");

// Monitor all transactions mentioning a specific address
const monitorAddress = (address) => {
  const request = {
    "jsonrpc": "2.0",
    "id": 6,
    "method": "logsSubscribe",
    "params": [
      {
        "mentions": [address]
      },
      {
        "commitment": "confirmed"
      }
    ]
  };
  
  ws.send(JSON.stringify(request));
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.method === "logsNotification") {
    const logs = data.params.result.value.logs;
    const signature = data.params.result.value.signature;
    
    console.log(`Transaction ${signature} mentioned our address`);
    console.log("Logs:", logs);
    
    // Parse logs for specific events or errors
    if (logs.some(log => log.includes("Program failed"))) {
      console.log("Transaction failed!");
    }
  }
};

// Monitor a token mint for all activity
monitorAddress("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v");

Implementasi Siap Produksi

Berikut adalah implementasi WebSocket yang andal dengan logika koneksi ulang, penanganan kesalahan, dan pengelolaan status yang tepat:

class WebSocketManager {
  constructor(endpoint) {
    this.endpoint = endpoint;
    this.ws = null;
    this.subscriptions = new Map();
    this.isConnected = false;
  }

  async connect() {
    this.ws = new WebSocket(this.endpoint);
    
    this.ws.onopen = () => {
      console.log('Connected');
      this.isConnected = true;
      this.resubscribeAll();
    };

    this.ws.onmessage = (event) => {
      const data = JSON.parse(event.data);
      
      // Handle subscription confirmations
      if (data.result && typeof data.result === 'number') {
        const sub = Array.from(this.subscriptions.values())
          .find(s => s.requestId === data.id);
        if (sub) sub.subscriptionId = data.result;
        return;
      }

      // Handle notifications
      if (data.method?.endsWith('Notification')) {
        const sub = Array.from(this.subscriptions.values())
          .find(s => s.subscriptionId === data.params.subscription);
        if (sub?.callback) sub.callback(data.params.result);
      }
    };

    this.ws.onclose = () => {
      console.log('Disconnected');
      this.isConnected = false;
      // Implement reconnection logic here
    };
  }

  subscribe(method, params, callback) {
    const requestId = Date.now();
    const subscription = { requestId, method, params, callback, subscriptionId: null };
    this.subscriptions.set(requestId, subscription);
    
    if (this.isConnected) {
      this.ws.send(JSON.stringify({
        jsonrpc: '2.0',
        id: requestId,
        method,
        params
      }));
    }
    
    return requestId;
  }

  resubscribeAll() {
    for (const [id, sub] of this.subscriptions) {
      sub.subscriptionId = null;
      this.ws.send(JSON.stringify({
        jsonrpc: '2.0',
        id,
        method: sub.method,
        params: sub.params
      }));
    }
  }
}

// Usage
const wsManager = new WebSocketManager('wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY');
await wsManager.connect();

// Subscribe to account changes
wsManager.subscribe(
  'accountSubscribe',
  ['account-address-here', { commitment: 'confirmed' }],
  (data) => console.log('Account updated:', data)
);

Pengoptimalan Performa

Connection Management
Memory Management

// Use connection pooling for multiple subscriptions
class WebSocketPool {
  constructor(endpoint, maxConnections = 3) {
    this.endpoint = endpoint;
    this.connections = [];
    this.maxConnections = maxConnections;
    this.currentConnectionIndex = 0;
  }
  
  async getConnection() {
    if (this.connections.length < this.maxConnections) {
      const wsManager = new SolanaWebSocketManager(this.endpoint);
      await wsManager.connect();
      this.connections.push(wsManager);
      return wsManager;
    }
    
    // Round-robin selection
    const connection = this.connections[this.currentConnectionIndex];
    this.currentConnectionIndex = (this.currentConnectionIndex + 1) % this.connections.length;
    return connection;
  }
}

// Implement subscription cleanup and memory management
class ManagedWebSocket extends SolanaWebSocketManager {
  constructor(endpoint, options = {}) {
    super(endpoint, options);
    this.maxSubscriptions = options.maxSubscriptions || 100;
    this.subscriptionHistory = [];
  }
  
  subscribe(method, params, callback) {
    // Check subscription limit
    if (this.subscriptions.size >= this.maxSubscriptions) {
      this.cleanupOldSubscriptions();
    }
    
    const requestId = super.subscribe(method, params, callback);
    
    // Track subscription for cleanup
    this.subscriptionHistory.push({
      requestId,
      timestamp: Date.now(),
      method
    });
    
    return requestId;
  }
  
  cleanupOldSubscriptions() {
    // Remove oldest 10% of subscriptions
    const toRemove = Math.floor(this.subscriptions.size * 0.1);
    const sortedHistory = this.subscriptionHistory
      .sort((a, b) => a.timestamp - b.timestamp);
    
    for (let i = 0; i < toRemove && i < sortedHistory.length; i++) {
      const sub = sortedHistory[i];
      this.unsubscribe(sub.requestId);
      
      // Remove from history
      this.subscriptionHistory = this.subscriptionHistory
        .filter(s => s.requestId !== sub.requestId);
    }
  }
}

Penanganan Kesalahan dan Debugging

Penanganan kesalahan yang andal sangat penting untuk aplikasi WebSocket produksi. Terapkan pola-pola ini untuk menangani masalah jaringan, batas laju, dan kesalahan API dengan baik.

class ErrorHandlingWebSocket extends SolanaWebSocketManager {
  constructor(endpoint, options = {}) {
    super(endpoint, options);
    this.errorCounts = new Map();
    this.maxErrorsPerMinute = options.maxErrorsPerMinute || 10;
  }

  handleMessage(data) {
    try {
      // Handle rate limiting
      if (data.error && data.error.code === 429) {
        console.warn('Rate limited, backing off...');
        this.handleRateLimit();
        return;
      }

      // Handle subscription errors
      if (data.error && data.error.code === -32602) {
        console.error('Invalid subscription parameters:', data.error.message);
        this.handleInvalidSubscription(data.id);
