JavaScript Twitter Search API Example

Today, I wanted to use the Public Twitter Search API and grab the latest 5 tweets tagged “jquery4u”. Twitter provide a bunch of useful REST API Resources which you can make use of without a Twitter account or any authentication (oAuth or such) to grab data from Twitter. The Twitter Search API can be used to grab tweets using queries such as ones that have specific keywords, hashtags, users, mentions, phrases etc… Here is how you can do it.

The JavaScript/jQuery

Here we can access the public feed from the Twitter search API and specify a JSON callback for the data.

Parameters:
q = the search string (make sure it’s uri encoded)
rpp = the number of tweets we want to get

//get the JSON data from the Twitter search API
$.getJSON("http://search.twitter.com/search.json?q=jquery4u&rpp=5&callback=?", function(data)
{
    //loop the tweets
    $(data.results).each(function(i,v)
    {
        //...see full code below
    }
}

The HTML

The CSS

.twitStream{
    font-family: verdana;
    font-size: 11px;
}
.twitStream a{
    font-family: verdana;
    font-size: 11px;
}
.tweet{
    display: block;
    padding: .4em;
    margin: .4em 0;
}
.tweet-left{
    float: left;
    margin-right: 1em;
}
.tweet-left img{
    border: 2px solid #000000;
}
.tweet p.text{
    margin: 0;
    padding: 0;
}
