are there some functions or method in the twitter-api streaming activity for the last time?

Question

I heard that the Stream () function is now outdated and will not function to stream twitter api, is there another function

I tried streaming twitter api with bot twitter on the follow function to find out what happened and I found an error

I'm looking for code errors that I made and I heard that the Stream () function is now outdated and will not function to stream twitter api, is there another function

this my code

// Setting up a user stream 
var stream = T.stream('user');

// Anytime someone follows me
stream.on('follow', followed);

function followed(eventMsg){
    console.log('follow event!');
    var name = eventMsg.source.name;
    var screenName = eventMsg.source.screen_name;
    tweetIt('@' + screenName + ' thank your follow me');
}

I hope to find a function or method in streaming this twitter api.
