🚀 Meet Messenger Flow: The Modern Node.js Library for Facebook Messenger Bots

Are you building Facebook Messenger bots and frustrated with outdated libraries?

I was in the same boat! BootBot was once the go-to library, but it hasn't kept up with Node.js updates and is no longer maintained. When I tried using BootBot with recent Node.js versions, I ran into compatibility issues and dead ends.

That's why I built Messenger Flow — a modern, actively maintained alternative that works out of the box with the latest Node.js versions. It's designed to be simple, flexible, and reliable, so you can focus on building great bots, not fighting with legacy code.

✨ Why Messenger Flow?

🟢 Modern Node.js Support: Built for the latest Node.js versions.
🧩 Simple API: Inspired by BootBot, but improved for today's needs.
🔄 Active Maintenance: Regular updates and support for new Messenger features.
📚 Clear Docs: Get started quickly with guides and examples.

📦 Installation

Install Messenger Flow using npm:

npm install messenger-flow

🤖 Quick Start: Your First Messenger Bot

Here's how to create a simple Messenger bot that replies "Hello, world!" to every message:

const MessengerFlow = require('messenger-flow');

const bot = new MessengerFlow({
  accessToken: 'YOUR_PAGE_ACCESS_TOKEN',
  verifyToken: 'YOUR_VERIFY_TOKEN',
  appSecret: 'YOUR_APP_SECRET', // optional, for advanced use
  webhook: '/webhook' // optional, default is '/webhook'
});

bot.on('message', (event, chat) => {
  chat.say('Hello World!');
});

bot.start(3000); // Start server on port 3000

How it works:

Initialize Messenger Flow with your Facebook app credentials.
Listen for incoming messages with bot.on('message', ...).
Reply using chat.say().
Start your bot server with bot.start().

Just replace the placeholders with your actual Facebook credentials, and you're ready to go!
