This is a simple flow which listens to a twitter feed and prints the details of the feed on the debug window
How to build this flow
Step 1: Drag Twitter Input and Set up Twitter
Drag the Twitter input node from the social palette and double click to set up twitter
Once you have your twitter credentials successfully set up , you can listen for words , @ids or hashtags
Step 2. Insert Debug and Function Nodes
Insert a Debug node and connect it to Twitter input and name the output to msg.tweet
Insert another Debug node and connect to Twitter Input and name the output msg.tweet.text
3 . Insert the function node connected to Twitter Input with the following code to remove urls from the tweet and replace #
// var tweet = msg.tweet.text;
var tweet = msg.payload;
var newtweet = tweet.replace(/#/g, " Hash tag ");
// regex from https://stackoverflow.com/questions/1500260/detect-urls-in-text-with-javascript
msg.payload = newtweet.replace( /(([a-z]+:\/\/)?(([a-z0-9\-]+\.)+([a-z]{2}|biz|com|co|edu|gov|info|net|org|ly))(:[0-9]{1,5})?(\/[a-z0-9_\-\.~]+)*(\/([a-z0-9_\-\.]*)(\?[a-z0-9+_\-\.%=&]*)?)?(#[a-zA-Z0-9!$&'()*+.=-_~:@/?]*)?)(\s+|$)/gi, "see short URL " );
return msg;
Insert a debug node connected to function Input and name the output msg.payload
Step 3. Deploy Flow
You should be able to see Tweets on the debug Panel
