Feedr NPM | npm.io

Use feedr to fetch the data from a remote url, respect its caching, and parse its data. Despite its name, it's not just for feed data but also for all data that you can feed into it (including binary data).

npm

Usage

// Create a new feedr instance
const feedr = require('feedr').create({/* optional configuration */})

// Prepare our feeds that we want read
const feeds = {
	someAtomFeed: 'https://github.com/bevry/feedr/commits/for-testing.atom'
	someJsonFile: 'https://raw.githubusercontent.com/bevry/feedr/for-testing/package.json'
}

// Read a single feed
feedr.readFeed(feeds.someAtomFeed, {/* optional configuration */}, function (err, data, headers) {
	console.log(err, data, headers)
})

// Read all the feeds together
feedr.readFeeds(feeds, {/* optional configuration */}, function (err, result) {
	console.log(err, result.someAtomFeed, result.someJsonFile)
})
