Boilerplate project for developing Facebook Messenger Bot powered by Wit.ai, MongoDB and Redis as a session store. This boilerplate will allow you to bootstrap your chatbot within 8 minutes, all you need is wit.ai application setup, Facebook page, Facebook app and running MongoDB and Redis.

The AI engine used in this boilerplate is wit.ai, please make sure to create a new app in the wit.ai dashboard.

This boilerplate is using MongoDB for storing user's data and for tracking their last activity with the bot Please install MongoDB v3 or greater and setup connection in the config/config.js

By default the in the development environment chatbotdb database will be created

Redis server is required for managing sessions and keeping the context with each user. Please install Redis and setup connection in the config/config.js

npm install

Set environment variables or write values directly in the config/config.js

FB_PAGE_TOKEN - Access token generated for the Facebook application to allow making Graph API requests to the page

WIT_TOKEN - WIT server side token
