Through conversational experiences people can interact with applications easier than ever before. For developers this means they have to understand how to build these natural user interfaces in addition to browser interfaces and mobile apps. In this session we will demonstrate live how to develop a chatbot for Slack. Via Node.js and the open source project botkit we'll connect to Slack's websocket API. In order to define the conversation flow we'll leverage intents, entities and dialogs from IBM Watson's Conversation service.
