Node-RED Twitter Workshop

These Node-RED flows use Twitter to introduce a variety of Node-RED visual programming techniques and simple ways to use the powerful Watson Cognitive services.

These Twitter Node-RED recipes showcase:

• A simple flow that watches a Twitter feed.
• Perform Sentiment analysis of Tweets. You could retweet positive tweets or SMS tweets to your friends
• Perform Tone analysis of Tweets using the Watson Tone Analyzer service
• Speak Tweets using the Watson Text to Speech service
• Store Tweets and Sentiment scores in a Cloudant database for historical analysis
• Build a Node-RED Dashboard that charts Twitter hashtag sentiment history
• Perform Image analysis of pictures attached to Tweets using the Watson Visual Recognition service
• Build a Nutrition Image Analysis dashboard to report the ingredients and nutritional information from the USDA
  • Tweet a picture of food and use the Watson Visual Recognition custom food classifier. Great fun!

You might want to learn from the Node-RED Twitter workshop that I wrote to teach Node-RED and Watson Cognitive services. Follow the step-by-step instructions to create all of these example flows.
