podparse
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.
Installation
npm install podparse
See podparse on npm.
Differences from jbierfeldt/podcast-feed-parser
This package:
- Does not contain the
isomorphic-fetch
dependency. - Replaces
xml2js
with 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
episodic
andserial
podcast types.

Overview
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
}
}
Quickstart
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"
Options
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
});
Real-world example
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.`,
