A simple WhatsApp bot built on top of Baileys.

• Event-driven architecture for handling WhatsApp events like ready, message, qr, and more.
• Send and receive messages with ease.
• Group management: join, leave, and fetch group metadata.
• Automatic reconnection with retry logic.
• Customizable options for session management, logging, and device configuration.

You can install fiwa using your preferred package manager, but I recommend using Bun:

bun i fiwa

Here is a basic example of how to use the library:

import { FiWhatsAppClient } from "fiwa";

const client = new FiWhatsAppClient({
  phoneNumber: "1234567890", // Optional: for pairing code
  maxRetries: 5, // Optional: retry attempts for reconnection
});

client.on("qr", (qr) => {
  console.log("Scan this QR code:", qr);
});

client.on("ready", () => {
  console.log("Client is ready");
});

client.on("message", (message) => {
  const jid = message.key.remoteJid;
  client.sendText(jid!, "Hello world!");
});

client.start();

fiwa uses the file system by default to store authentication state. However, fiwa now supports using MongoDB to store authentication state. This is useful for scenarios where you want to persist session data in a NoSQL database instead of the file system.

To use MongoDB for session state, provide the mongodb option when creating the FiWhatsAppClient instance:

const client = new FiWhatsAppClient({
  mongodb: {
    url: "<your-mongodb-url>",
    databaseName: "<your-database-name>", // Optional, defaults to "fiwa"
    collectionName: "<your-collection-name>", // Optional, defaults to "fiwa_auth_state"
  },
});

import { FiWhatsAppClient } from "fiwa";

const client = new FiWhatsAppClient({
  mongodb: {
    url: "mongodb+srv://...",
  },
});

client.on("ready", () => {
  console.log("Client is ready");
});

client.start();

When using MongoDB, the library will automatically handle storing and retrieving authentication credentials and keys from the specified collection.

new FiWhatsAppClient(options?: FiWhatsAppOptions);
