Async-Feedbag

Async-Feedbag is a fork of Ruby's favorite auto-discovery tool/library, using async-http for the requests.

>> require "async-feedbag"
=> true
>> AsyncFeedbag.find "damog.net/blog"
=> ["http://damog.net/blog/atom.xml"]
>> AsyncFeedbag.feed? "perl.org"
=> false
>> AsyncFeedbag.feed?("https://m.signalvnoise.com/feed")
=> true

$ gem install async-feedbag

You can also use the command line tool for quick queries, if you install the gem:

» feedbag https://www.ruby-lang.org/en/
== https://www.ruby-lang.org/en/:
- https://www.ruby-lang.org/en/feeds/news.rss

Feedbag will find all RSS feed types. Here's an example of finding ATOM and JSON Feed

> AsyncFeedbag.find('https://daringfireball.net')
=> ["https://daringfireball.net/feeds/main", "https://daringfireball.net/feeds/json", "https://daringfireball.net/linked/2021/02/17/bookfeed"]

Feedbag defaults to a User-Agent string of AsyncFeedbag/1.10.2, however you can override this

0> AsyncFeedbag.find('https://kottke.org', 'User-Agent' => "My Personal Agent/1.0.1")
=> ["http://feeds.kottke.org/main", "http://feeds.kottke.org/json"]

The other options passed to find, will be passed to OpenURI. For example:

AsyncFeedbag.find("https://kottke.org", 'User-Agent' => "My Personal Agent/1.0.1", open_timeout: 1000)

You can find the other options to OpenURI here.

• Because it only uses Nokogiri as dependency.
• Because it follows modern feed filename conventions (like those ones used by WordPress blogs, or Blogger, etc).
• Because it's a single file you can embed easily in your application.
• Because it's faster than anything else.
