Developing a Messenger chatbot with node.js
With the example of http://toni.football/, the Euro 2016 Chatbot, he will show how to create a bot for Facebook Messenger using node.js. The technology stack includes a bot engine for natural language processing (NLP) and MongoDB for storing data. The code can be hosted at Google App Engine with minimal effort.
