Vott for Messenger (i.e. vott-messenger) is a minimal, extensible framework for building Messenger bots.

Features

• Fully extensible conversational flow (middleware and plugins)
• Serves multiple pages from a single instance
• Scoped questions for complex conversational trees
• Thoroughly tested and secure

Simplicity First

In order to keep vott as simple as possible, vott makes no assumption on state-management, persistence layers, or message-processing functionality. Extra functionality must be provided by developers and third-party plugins or middleware.

Installation

$ npm install --save vott-messenger

Quick Example

const MessengerBot = require('vott-messenger')

/** instantiate MessengerBot */
const myBot = new MessengerBot({
  access_token: process.env.FB_PAGE_ACCESS_TOKEN,
  verify_token: process.env.FB_VERIFY_TOKEN,
  endpoint: '/facebook/receive'
})

/** usage example: */
myBot.on('message_received', (bot, event) => {
  bot.chat(event, (chat) => {
    chat.say('Hello!')
    chat.ask('How are you?', (res, chat) => {
      chat.save({ user_status: res.text })
      chat.say('Ok')
      chat.next()
    })
    chat.next()
  })
})

myBot.setupServer(process.env.PORT, (err, server) => {
  if (err) throw Error(err)
  console.log(`Server listening on port ${process.env.PORT}`)
}).setupWebhooks()
