indieweb-endpoints-ruby
A Ruby gem for discovering a URL's IndieAuth, Micropub, Microsub, and Webmention endpoints.
Key Features
- Compliant with Section 4.1 and Section 4.2.2 of the W3C's IndieAuth Working Group Note, Section 5.3 of the W3C's Micropub Recommendation, and Section 3.1.2 of the W3C's Webmention Recommendation.
- Passes all Endpoint Discovery tests on webmention.rocks.
- Supports Ruby 2.7 and newer.
Getting Started
Before installing and using indieweb-endpoints-ruby, you'll want to have Ruby 2.7 (or newer) installed. It's recommended that you use a Ruby version managment tool like rbenv, chruby, or rvm.
indieweb-endpoints-ruby is developed using Ruby 2.7.6 and is additionally tested against Ruby 3.0 and 3.1 using GitHub Actions.
Installation
If you're using Bundler, add indieweb-endpoints-ruby to your project's Gemfile
:
source 'https://rubygems.org'
gem 'indieweb-endpoints'
…and hop over to your command prompt and run…
$ bundle install
Usage
Basic Usage
With indieweb-endpoints-ruby added to your project's Gemfile
and installed, you may discover a URL's IndieWeb-relevant endpoints by doing:
require 'indieweb/endpoints'
IndieWeb::Endpoints.get('https://aaronparecki.com')
#=> { authorization_endpoint: "https://aaronparecki.com/auth", "indieauth-metadata": "https://aaronparecki.com/.well-known/oauth-authorization-server", micropub: "https://aaronparecki.com/micropub", microsub: "https://aperture.p3k.io/microsub/1", redirect_uri: nil, token_endpoint: "https://aaronparecki.com/auth/token", webmention: "https://webmention.io/aaronpk/webmention" }
This example will search https://aaronparecki.com
for valid IndieAuth, Micropub, and Webmention endpoints and return a Hash
of results. Each key in the returned Hash
will have a value of either a String
representing a URL or nil
. The redirect_uri
key's value will be either an Array
or nil
since a given URL may register multiple callback URLs.
Advanced Usage
Should the need arise, you may work with the IndieWeb::Endpoints::Client
class:
require 'indieweb/endpoints'
client = IndieWeb::Endpoints::Client.new('https://aaronparecki.com')
#=> #<IndieWeb::Endpoints::Client uri: "https://aaronparecki.com">
client.response
#=> #<HTTP::Response/1.1 200 OK {…}>
client.endpoints
#=> { authorization_endpoint: "https://aaronparecki.com/auth", micropub: "https://aaronparecki.com/micropub", microsub: "https://aperture.p3k.io/microsub/1", redirect_uri: nil, token_endpoint: "https://aaronparecki.com/auth/token", webmention: "https://webmention.io/aaronpk/webmention" }
Exception Handling
There are several exceptions that may be raised by indieweb-endpoints-ruby's underlying dependencies. These errors are raised as subclasses of IndieWeb::Endpoints::Error
(which itself is a subclass of StandardError
).
