Usage

To use the channel, you need a web server for FB to send messages and postbacks to. Then you can add the messenger middleware to it. Here's an example using express.

const { BotEngine, InMemorySessionManager } = require('@bot-engine/core');

const engine = new BotEngine(new InMemorySessionManager(), {
    // Your default flow.
});

// Register other flows and plugins.

const MessengerChannel = require('@bot-engine/channel-messenger').default;
const express = require('express');

const messengerChannel = new MessengerChannel({
    token: 'YOUR_TOKEN',
    verify: 'YOUR_VERIFICATION_TOKEN',
    appSecret: 'YOUR_APP_SECRET',
});

engine.register(messengerChannel);

const app = express();

app.use(messengerChannel.middleware());

app.listen(3000, () => {
    console.log('Listening...');
});

engine.start();
