This flow provides an example of using the Sentiment analysis node to read Tweets and apply a sentiment rating in real-time. In this example the processed tweet is displayed in a Node-Red Dashboard element alongside a dial indicating the tweets sentiment rating. The dashboard is accessible via the existing Node-Red httpRoot path with /UI added. On the localhost this would be http://127.0.0.1:1880/ui.
Note: In order to use the Twitter Stream Node the user will need to sign up for a Twitter developer account and set up a Twitter app. See Twitter developer apps: Overview.
