📦 RedisStore for Baileys

The RedisStore class provides an efficient way to manage and cache messages, chats, contacts, and more using Redis. This class integrates seamlessly with the Baileys library and offers a robust solution for handling and storing WhatsApp-related data.

🚀 Features

• 🔗 Redis Integration: Connects to a Redis server to store and manage data.
• 🔄 Event Handling: Listens and responds to various Baileys events such as connection updates and message reactions.
• 💾 Data Caching: Implements caching for messages to improve performance and reduce Redis load.
• 🔍 Message Search: Provides functionality to search for messages based on different criteria.
• 🗑️ Data Clearing: Allows clearing all cached data from Redis and local storage.

🛠️ Installation

To use RedisStore, you'll need to install the necessary dependencies. Run the following command:

npm install baileys-redis-store

⚙️ Configuration

To set up RedisStore, create a new instance by providing the required configuration options:

import pino from 'pino';
import { RedisStore } from 'baileys-redis-store'; // Adjust the import path as necessary

// Create a Redis client with connection options
const redisClient: RedisClientType = createClient({
    url: "YOUR REDIS URL"
});

// Create a RedisStore instance for managing WhatsApp session data
const store = new RedisStore({
    redisConnection: redisClient,
    prefix: 'store', // Optional prefix for Redis keys
    logger: pino({ level: 'debug' }), // Optional Pino logger instance
    maxCacheSize: 5000, // Maximum number of messages to cache locally (defaults to 1000)
});

📚 Usage Example

Here's a basic example of how to use the RedisStore:

import makeWASocket, { useMultiFileAuthState } from '@whiskeysockets/baileys';
import { RedisStore } from 'baileys-redis-store'; // Import RedisStore for managing Redis-based session storage
import pino from 'pino'; // Import Pino for logging
import { createClient, RedisClientType } from 'redis'; // Import Redis client utilities

/**
 * Main function to set up the WhatsApp socket connection and Redis store.
 */
async function main() {
    // Create a Redis client with connection options
    const redisClient: RedisClientType = createClient({
        url: "YOUR REDIS URL"
    });

    // Handle Redis connection errors
    redisClient.on('error', (err) => {
        console.error('Redis Client Error:', err);
        // Optionally attempt to reconnect
        // setTimeout(() => redisClient.connect(), 5000); // Retry connection after 5 seconds
    });

    // Connect to the Redis server
    try {
        await redisClient.connect();
        console.log('Connected to Redis successfully!');
    } catch (error) {
        console.error('Error connecting to Redis:', error);
        return; // Exit if connection fails
    }

    // Create a RedisStore instance for managing WhatsApp session data
    const store = new RedisStore({
        redisConnection: redisClient,
        prefix: 'store', // Optional prefix for Redis keys
        logger: pino({ level: 'debug' }), // Optional Pino logger instance
        maxCacheSize: 5000, // Maximum number of messages to cache locally (defaults to 1000)
    });

    // Load authentication state from multi-file storage
    const { state, saveCreds } = await useMultiFileAuthState('./Test');

    // Create a WhatsApp socket connection with the specified configuration
    const sock = makeWASocket({
        auth: state,
        printQRInTerminal: true,
        getMessage: store.getMessage.bind(store), // Bind the context for getMessage method
    });

    // Listen for credentials updates and save them
    sock.ev.on('creds.update', saveCreds);

    // Bind the store to the WhatsApp socket event emitter
    await store.bind(sock.ev as any);

    // Handle incoming messages
    sock.ev.on('messages.upsert', async ({ messages }) => {
        const msg = messages[0];

        // Example of loading a specific message by ID
        const loadMessage = store.loadMessage("12343434@jid", "04FC413D6BE3C1XXXX");
        
        // Example of loading the latest messages (up to 40) for a specific chat
        const loadMessages = store.loadMessages("12343434@jid", 40);
    });

    // Gracefully disconnect from Redis on process exit
    process.on('SIGINT', async () => {
        console.log('Disconnecting from Redis...');
        await redisClient.quit();
        console.log('Disconnected from Redis.');
        process.exit(0); // Exit cleanly
    });
}

// Execute the main function and handle any errors
main().catch((error) => {
    console.error('Main function error:', error);
});
