Usage

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

import { Client } from 'waba';

const client = new Client({
    port: 3000, // optional, default is 3000
    host: '127.0.0.1', // optional, default is '127.0.0.1'
    phone_number_id: 'YOUR_PHONE_NUMBER_ID', // optional
    app_secret: 'YOUR_APP_SECRET',
    webhook_token: 'YOUR_WEBHOOK_VERIFY_TOKEN',
    whatsapp_token: 'YOUR_WHATSAPP_API_TOKEN',
});

client.on('message', async (ctx) => {
    console.log('New message received:', ctx.message);
    // Reply to the message
    await ctx.reply('We have received your message!');
});

client.start();

Webhook Setup

To use this library, you need to set up a webhook in your Meta application.

1. Webhook URL: Set your webhook URL to http://<your_host>:<port>/webhook.
2. Verify Token: Use the same verify token that you provided in the webhook_token option.

The library will automatically handle the webhook verification for you.
