A simple node.js RSS feed builder
None of the other node.js RSS modules that I could find supported the flexibility that I wanted or were too slow. Additionally, many of them seemed overly complex when all we're doing here is building a RSS feed. Not rocket science.
npm install node-rss
Update (6/18/2015): This step should no longer be necessary.
node-rss uses the libxmljs library to construct the actual feed. Unfortunately, some of the features of the library that are needed are only available in the current master branch. You will need to download the libxmljs source, compile, and install it yourself. Fortunately, this is fairly straight forward. https://github.com/polotek/libxmljs/
You will also need to have the libxml2 AND libxml2-dev packages installed on your system.
// this exposes two methods: createNewFeed and getFeedXMLvar rss = ;// first we create a "feed" object that will define your feed// method signature: function createNewFeed(title, link, desc, author, feedLink, options)// title : title of your feed// link : link to your website// desc : description of your feed// author : author of the feed// feedLink : link to the feed// options : additional options, explained belowvar feed = rss;// the additional options parameter can essentially be used to// arbitrarily change the xml that will be created or other defaults.// currently, it only supports basic tags, where it will take a// key : value and turn it into <key>value</key>, but future releases// will contain the ability to specify attributes//next, we need to add some items to the feed// create some dummy data to loop over...var blogs =title: 'blog post 1' url : '' pubDate : description: 'this is a description'title: 'blog post 2' url : '' pubDate : description: 'this is a description'title: 'blog post 3' url : '' pubDate : description: 'this is a description'title: 'blog post 4' url : '' pubDate : description: 'this is a description'title: 'blog post 5' url : '' pubDate : description: 'this is a description'title: 'blog post 6' url : '' pubDate : description: 'this is a description';// add some items to the feed// each feed object has a function addNewItem which should be used for adding new items// method signature : function addNewItem(itemTitle, itemLink, pubDate, description, fields)// itemTitle : Title of the item// itemLink : Link to the item// pubDate : Date the item was created/published// description : description of item// fields : functions exactly like the "options" parameter of createNewFeed,// allows the user to add arbitrary tags to an itemblogs;// now to get the XML simply call the getFeedXML functionvar xmlString = rss;
The "feed" object has a defaults property. Inside this is a dictionary of default values.
cdata : a list of tag names whose content should be "escaped" in CDATA tags
In the process of building these...
- add tests - add support for attributes on custom tags - add some express.js middleware - ?? give me suggestions
Version 1.0.5 - Updated libxml version to 0.15.x to support node.js 4.x (Thanks @dhendo)
Version 1.0.4 - Updated libxml version to 0.14.x to support compilation on OSX (Thanks @jmathews)
Version 1.0.3 - update libxml version to 0.13.0
