Because Tessel runs Node, we can leverage the thousands of libraries that the Node community has made.
This code snippet makes Tessel send a tweet from a dummy account (@TesselTweet) that we've created for this purpose.
Create a new directory within your "tessel-code" directory:
mkdir tessel-tweet; cd tessel-tweet; t2 init
Use npm to install the Twitter library that the Node.js community has built:
npm install twitter
Rename the "index.js" file you've just created to "tweet.js", then copy and paste the below script over the existing text:
{% highlight javascript %} // Node requires var twitter = require('twitter');
var twitterHandle = '@tesselproject'; // The status to tweet var status = 'Hello ' + twitterHandle + '. This is your #Tessel 2 speaking.';
// These OAuth credentials are for the dummy @TesselTweet account // Paste in your own OAuth details if you want to tweet from your own account var twit = new twitter({ consumer_key: 'O7oc0pvsZn4xjgcuHuYdX4FaC', consumer_secret: 'iJYuHFz2sD46Nvk3mcwzX8uih14aEAMgVWdWoR59nx8v6Zl7ZX', access_token_key: '2529232909-luARGU89K4CKFMvfzBjCgG6ubefzDkdDWkSB85i', access_token_secret: 'GXQfuzvGdjLEs3t1HEYfhQ9x9bdBcSBVXjBkbRgwYlOE0' });
// Make a tweet! twit.post('statuses/update', {status: status}, function(error, tweet, response){ if (error) { console.log('error sending tweet:', error); } else { console.log('Successfully tweeted! Tweet text:', tweet.text); } }); {% endhighlight %}
Change the "twitterHandle" var to your own Twitter handle and save.
Make sure you're [connected to Wifi]({{ site.baseurl }}/wifi.html), then run:
t2 run tweet.js
Bonus: Try making Tessel tweet output from a module.
Extra bonus: What's another Node module you can try out? Maybe Twilio, PubNub, Plotly, Firebase? Surf around on npm until you find a Node library you like, then try using it with Tessel.
