A simple package for parsing podcast feeds into consistent, manageable JavaScript objects. For use with Node and in the browser. Originally based on jbierfeldt/podcast-feed-parser, but optimized and with fewer runtime dependencies.
npm install podparse
See podparse on npm.
This package:
- Does not contain the
isomorphic-fetchdependency. - Replaces
xml2jswith smaller and less memory-intensive@rgrove/parse-xml. - Is designed to be easier to use, albeit less configurable.
- Removes empty (
null,undefined,'',NaN,{}) from the output. - Does not use hard-coded namespace prefixes (esp.
itunes,googleplay, andatom). - Handles episode sorting for both
episodicandserialpodcast types.

By default, podparse will parse a podcast's xml feed and return an object with the following properties. meta contains all of the information pertinent to the podcast show itself, and episodes is list of episode objects which contain the information pertinent to each individual episode of the podcast.
{
meta: {
title: 'My podcast',
description: 'A podcast about whatever',
// ...
},
episodes: [
{
title: 'My Episode 1',
description: 'Episode 1',
pubDate: '2018-11-29T10:30:00.000Z',
// ...
}, {
title: 'My Episode 2',
description: 'Episode 2',
pubDate: '2018-11-28T10:30:00.000Z',
// ...
}
],
liveEpisodes: [ ] // Optional Podcast 2.0 Namespace
}
}podparse has a single function: getPodcastFromFeed:
const getPodcastFromFeed = require("podparse")
const fs = require('fs')
const podcastFeed = fs.readFileSync('path/to/podcast-feed.xml', 'utf8')
const podcast = getPodcastFromFeed(podcastFeed)
console.log(podcast.meta.title)
// "My Podcast"
podcast.episodes.forEach( (episode) => {
console.log(episode.title)
})
// "My Episode 1"
// "My Episode 2"podparse currently supports the following options:
includeEpisodes(default:true)- Whether to parse
<item>and<podcast:liveItem>elements for each episode.
- Whether to parse
Options are passed as an object to the getPodcastFromFeed function, for example:
const podcastWithoutEpisodes = getPodcastFromFeed(podcastFeed, {
includeEpisodes: false
});podparse will parse a feed for values based on this standard. If a field is not found in a feed, it will not be included. Here is a sample output for Planet Money:
{
meta: {
title: 'Planet Money',
description: `The economy explained. Imagine you could call up a friend and say, "Meet me at the bar and tell me what's going on with the economy." Now imagine that's actually a fun evening.`,

}More examples can be found in test/json, including converstions of all valid RSS feeds in test/testfiles. See test/convert.js for conversion code.
To execute mocha tests run:
npm run-script test
podparse is tested every day against hundreds of thousands of real-world podcast RSS feeds as part of PodLP, a podcast app for KaiOS smart feature phones.
