Usage

Collection script

To start collecting tweets from your "universe" via the twitter gardenhose, create a script containing the following...

var jugo = require('jugo');

var J = jugo({
  "twitter" : {
    "consumer_key": "<INSERT KEY>",
    "consumer_secret": "<INSERT KEY>",
    "access_token": "<INSERT KEY>",
    "access_token_secret": "<INSERT KEY>"
  },
  "accounts" : [
    ... // list of accounts you want to track
  ],
  "database" : "mongodb://localhost/test" // database location
})

// start collecting
J.collect();

And then run it as a background process. This will collect tweets as they come in, as well as metadata scraped from the urls. The collection script creates two mongo collections posts and meta which contain documents of the following schema...

// example post document
{
  url : post_url,
  date : new Date(tweet.created_at),
  account : tweet.user.screen_name,
  followers : tweet.user.followers_count,
  retweets : tweet.retweet_count,
  favorites : tweet.favorite_count
}

// example meta document
{
  url : url,
  title : ..., // open graph protocol title
  image : ...,// open graph protocol image
  author : ..., // open graph protocol author
  description : .., // open graph protocol description
  date : ..., // open graph protocol date
}

Usage in a web app

Jugo also provides a little wrapper for aggregating and accessing the tweets in the database. For example, in node express application, one might use Jugo as follows...

var jugo = require('jugo');

var J = jugo(jugo_config);

// open jugo database connection when app starts
J.open(function() {
  console.log('database open!')
});

// database query api
app.get('/get/:query', function(req, res) {
  var params = getJsonFromUrl(req.params.query);

  var max, min;

  if (params.max) {
    var date_num = parseInt(params.max);
    if (!isNaN(date_num)) {
      max = new Date(date_num);
    }
  }

  if (params.min) {
    var date_num = parseInt(params.min);
    if (!isNaN(date_num)) {
      min = new Date(date_num);
    }
  }

  //
  // Use jugo "get" method to find top 40 stories
  // (currently ranked by number of tweets)
  // returns ...
  // {
  //   url : (shared url)
  //   count : (number of shares in specified timeframe)
  //   meta : (object containing scraped OG protocol metadata)
  // }
  //
  J.get(
    {
      max_date : max,
      min_date : min,
      num : 40
    },
    function(results) {
      res.send(results);
    }
  );
})
