jquery-rss
Advanced tools
This plugin can be used to read a RSS feed and transform it into a custom piece of HTML.
A vanilla JavaScript version of this library can be found here: Vanilla RSS. This plugin uses Feedr, a backend server that parses and converts RSS feeds into its JSON representation. The server was built as a drop-in replacement for Google's former Feed API.
Since version 3.4.0 of jquery.rss, users have the chance to support funding future developments and covering the costs for the hosting of jquery.rss' respective server side companion app feedr.
Every once in a while supporters will get affiliate links instead of one of the feed's entries.
If you are not interested in supporting the authors of the plugin, then you can easily opt-out of it by setting the respective
support option. See below for further details.
Thanks in advance!

$ npm install jquery
$ npm install jquery-rss

Note: Moment.js is optional. If you include it, jquery.rss will use it to format dates. If you do not want to include Moment.js, you may opt for providing your own date formatting function, or for not formatting dates at all.
$("#rss-feeds").rss(
// You can either provide a single feed URL or a list of URLs (via an array)
"http://feeds.feedburner.com/premiumpixels",
{
// how many entries do you want?
// default: 4
// valid values: any integer

// callback function
// called after feeds are successfully loaded and after animations are done
function callback() {}

Since version 3.0.0 the plugin is no longer using the Google Feed API but a drop-in replacement called feedr. That server is currently running on Heroku and might have some downtimes, interruptions or unexpected issues. While I will try to keep those problems as rare as possible, it can totally happen from time to time. I might move the service to some other provide or even improve the infrastructure.
If you don't want to rely on the provided server and instead run your own version, you can just download feedr, install the dependencies and run it. As written above, you can specify the host which is used to parse the feeds with the host option.
As seen in the options, you can specify a template in order to transform the json objects into HTML. In order to that, you can either define the outer template (which describes the html around the entries) or the entry template (which describes the html of an entry).
The basic format of those templates are:
<!-- layoutTemplate: -->
"<outer-html>{entries}</outer-html>"
<!-- entryTemplate: -->
"<any-html>{token1}{token2}</any-html>"
So, let's say you have specified a limit of 2, using the upper pseudo html. This will result in the following:
<outer-html>
<any-html>{token1}{token2}</any-html>
<any-html>{token1}{token2}</any-html>
</outer-html>
There are some predefined tokens:
You can also define custom tokens using the tokens option:
$("#foo").rss(url, {
entryTemplate: "{dynamic}, {static}, {re-use}",
tokens: {
dynamic: function(entry, tokens) {
return "dynamic-stuff: " + entry.title;
},
"re-use": function(entry, tokens) {
return encodeURIComponent(tokens.teaserImageUrl);
},
static: "static"
}
});
Please make sure to NOT define infinite loops. The following example is really BAD:
$('#foo').rss(url, {
entryTemplate: "{loop}",
tokens: {
whoops: function(entry, tokens) { return tokens.loop() }
loop: function(entry, tokens) { return tokens.whoops() }
}
})
Here is a real-world example:
$("#foo").rss(url, {
layoutTemplate: "<table><tr><th>Title</th></tr>{entries}</table>",
entryTemplate: "<tr><td>{title}</td></tr>"
});
The plugin also allows you to filter specific entries in order to only print them:
$("#foo").rss(url, {
limit: 100,
filterLimit: 10,
filter: function(entry, tokens) {
return tokens.title.indexOf("my filter") > -1;
}
});
This will request 100 entries via the Feed API and renders the first 10 matching entries.
The test suite is using BusterJS. In order to successfully run the tests you will need phantomjs.
If that is installed you only have to run npm test.
