RSS Feed Parser for Parse Cloud Code

A RSS Feed parser for Parse Cloud Code which is useful if you want the content of a RSS feed to end up in the Parse data store.

Installation

Download the module from Releases (e.g. rssparser-1.0.0.js) and place it in your cloud directory.

To use the module in your Cloud Code functions, start by requiring it and initializing it with your credentials:

var parser = require('cloud/rssparser-1.0.0.js');
parser.initialize('URL', 'CLASS');
parser.parse(success,error,map);

Documentation

initialize()

Takes an URL and a class name as input e.g parser.initialize('http://example.com/rss', 'Example');

parse()

Takes 3 callback functions as input: success, error and map.

• success: called when parsing of the RSS feed has completed. Takes no arguments.
• error: called if something bad happens. Takes a single argument which is an error object/dictionary.
• map: called for every item in the feed and expects a dictionary returned matching the keys of your Parse object. IMPORTANT NOTICE: The "first" item in the return dictionary will be used to lookup an existing object and create/update it accordingly. Please see the Example section below.

Example

Parse.Cloud.job("NewsFeed", function(request, status) {
    var parser = require('cloud/rssparser-1.0.0.js');
    parser.initialize('https://news.ycombinator.com/rss', 'News');
    parser.parse(function () {
        status.success('Finished!');
    },
    function(error) {
        status.error('Request failed with error ' + error);
    },
    function(item) {
        var mappedItem = new Array();
        mappedItem['commentsLink'] = item['comments'];
        mappedItem['link'] = item['link'];
        mappedItem['title'] = item['title'];
        return mappedItem;
    });
});

Roadmap

1. Allow objects as parameters e.g. with initialize()
   Alternatively pass an object with url and className e.g. parser.initialize({url: 'http://example.com/rss', className: 'Example'});

2. Support the use of Promises parser.parse(map(item){}).then()
