Build Status

This is a direct clone from https://github.com/bobby-brennan/rss-parser

I have removed the node dependencies so that it works with webpack in browser.

All credits should go to bobby-brennan.

Installation

You can install via npm:

npm install --save rss-parser-browser
# or
yarn add rss-parser-browser

Usage

You can parse RSS from a URL or a string.

  • parseString(xml, [options,], callback)

  • parseURL(url, [options,] callback)

Output

Check out the full output format in test/output/reddit.json

Notes:
  • The dc: prefix will be removed from all fields
  • Both dc:date and pubDate will be available in ISO 8601 format as isoDate
  • If author is specified, but not dc:creator, creator will be set to author (see article)

Usage

var parser = require('rss-parser-browser');

parser.parseURL('https://www.reddit.com/.rss', function(err, parsed) {
  console.log(parsed.feed.title);
  parsed.feed.entries.forEach(function(entry) {
    console.log(entry.title + ':' + entry.link);
  })
})

Redirects

By default, parseURL will follow up to one redirect. You can change this with options.maxRedirects.

parser.parseURL('https://reddit.com/.rss', {maxRedirects: 3}, function(err, parsed) {
  console.log(parsed.feed.title);
});

Custom Fields

If your RSS feed contains fields that aren't currently returned, you can access them using the customFields option.

var options = {
  customFields: {
    feed: ['otherTitle', 'extendedDescription'],
    item: ['coAuthor','subtitle'],
  }
}
parser.parseURL('https://www.reddit.com/.rss', options, function(err, parsed) {
  console.log(parsed.feed.extendedDescription);

  parsed.feed.entries.forEach(function(entry) {
    console.log(entry.coAuthor + ':' + entry.subtitle);
  })
})

To rename fields, you can pass in an array with two items, in the format [fromField, toField]:

var options = {
  customFields: {
    item: [
      ['dc:coAuthor', 'coAuthor'],
    ]
  }
}

Running Tests

The tests run the RSS parser for several sample RSS feeds in test/input and outputs the resulting JSON into test/output. If there are any changes to the output files the tests will fail.

To check if your changes affect the output of any test cases, run

npm test

To update the output files with your changes, run

WRITE_GOLDEN=true npm test
