Learning objectives

In this course, you’ll learn how to use the Node-RED flow editor to wire application components together to make a working application.

This course includes four hands-on labs that show you how to:

  • Create a simple Node-RED boilerplate application in IBM Bluemix
  • Build a web page and create a REST API in Node-RED
  • Translate text, analyze tone, add audio, and send tweets from a Node-RED application by using IBM Watson cognitive services
  • Create a Facebook Messenger bot and connect it to the Watson Conversation service

By completing these labs, you’ll learn to work with the following Watson services in Node-RED and Bluemix applications:

  • Speech to Text
  • Language Translator
  • Tone Analyzer
  • Conversation
  • Text to Speech
  • Cloudant database

You’ll also learn how to connect the Watson Conversation service to Facebook Messenger, use techniques that allow CSS and browser JavaScript reuse, and use media utilities to separate audio from a video stream for translation.
