Wow I cant believe someone literally enjoys teaching like that! Its 4 AM and Im stuck in thease videos.

[@santhoshjallu926]

If you're using this now the twitter removed the user endpoint so T.stream("user") doesn't work use var stream = T.stream('statuses/filter', { track: '@' }); instead.

[@saitejaballa6759]

Does the "your_twitter_username" Refers to the bot username?

Hey Daniel! Just came across this video series and has helped me setup and run a local node server to pull the current spot rate from my power company API so I can use it to calculate the cost of power via an IoT device power meter I created... speaking of which I would love to see a series on Arduino!

I have implemented this idea: a small joke bot in twitter that posts a joke every 1 hour.

[@shivamparashar641]

How did you do that, did you manually inserted each joke in a variable and passed it inside the post() or something else. I need the answer ?

[@TheGBsXB]

Shivam parashar use an array of string jokes and increment its index for each post, or look for a random jokes API and connect it to your bot so you can get new jokes each time your bot's posts.

If you are watching this now, the Stream() function is now obsolete and will not work. Instead, use the Account Activity API, it's a premium service but you can use it for free to test in the Sandbox. Find more info for in the twitter documentation by searching Account Activity API.

[@TheCodingTrain]

Thanks for the tip!

I made a Tweeting Cat's bowl with an Arduino. it posted when the cat's bowl became close to empty, and alerted my nephews to feed the cat. Interesting to see tweeting from NodeJS, but very similar restrictions (frequency, message similarity etc)

[@blasttrash]

did you use arduino as a server? do you keep it running all day? If so, how do you handle the security, firewalls etc?

[@guybegroovin2666]

[@BarbarosYurttagul]

Hello Daniel, in follow event, I see that; if I-me-myself follow a user, my bot works again. For example; my screen name in twitter is @BarbarosYrttgl. If I follow someone, tweetIt( ) function works and it says '.@BarbarosYrttgl thanks for following'. So, for the solution I recommend; function followed(eventMsg) { var name = eventMsg.source.name var screen_name = eventMsg.source.screen_name //id_str is your twitter account id if (eventMsg.source.id_str !== 'your_twitter_account_id_here') { tweetIt('.@' + screen_name + ' thanks for following') } } Great tutorial:)Thanks.

eventMsg is JSON data that was pulled from the stream.on followed event. It can be named anything. Think of it similar to a click event (eventListeners) and you want to pull where the User clicked on... (ie. event.target)

[@steffeneers2607]

Daniel, great videos for beginners! I hope you also can offer some help for further questions. I'm looking for the twitter command to identify, if my bot has already retweeted a specific tweet. In Twitter developers I have found current_user_retweet. But I have no idea how to use it. Do you?

I would keep track of a list of tweet IDs yourself and then compare from your code.

How to send message directly to the particular user

[@tiny-starship]

so I'm having a strange error setInterval while following this video. I'm trying to pass a parameter into the tweetIt function, which is contained within a setInterval and it keeps bombing out on the second interval. It took me awhile to narrow it down, but i have these two code samples: This works: setInterval(log,1000); function log() { console.log("log"); } this does not: setInterval(log("test"),1000); function log(txt) { console.log(txt); } The big picture idea is to call a function like this: setInterval(tweetIt(generateTweet),5000); the generateTweet function generates a string based on the time of day, weather, whatever. tweetIt then tweets the string, but it only works once before bombing out with this error C:\Dropbox\webDev\www ode>node notworking test timers.js:275 timer._repeat(); ^ TypeError: timer._repeat is not a function at wrapper [as _onTimeout] (timers.js:275:11) at Timer.listOnTimeout (timers.js:92:15) C:\Dropbox\webDev\www ode>

+Tiny Starship as usual 1 minute after posting a cry for help I figure it out. I had to change it to an anonymous function and it started working! thanks for the whole series, watched everyone and it helped me create a fake news bot for a game I'm creating. Working on making it a little more interactive. You mentioned in video 6 or 7 about creating a video on deploying our scripts to a server. Right now I'm just running it off of my iMac at home, would love to see that video :) Now this works: setInterval(function(){log("test")},1000); function log(txt) { console.log(txt); }

[@rjsantos6675]

If I create an animation that is based on if somebody twits, for example make a ball bounce everytime there is mention of the hashtag 'basketball', i should use stream(), correct? Thanks for these awesome lessons!

Late response but uf someone else sees this, you need to use the npm package called "request" which can make requests to urls and get the response as a raw string.
