rodauth-oauth VS rodauth-rails

It depends on what you mean by OAuth 2.0. If you want your app to be an OAuth 2.0 provider, then you'd use rodauth-oauth. If you want to enable your users to login through external apps that implement the OAuth 2.0 protocol, then OmniAuth is what you'd use. Not all external apps implement login via the OAuth 2.0 protocol, those that do will have their OmniAuth strategies inherit from omniauth-oauth2.

I want to make it easier for 3rd-party Rodauth extensions to provide migrations/views for Rails generators. The rodauth-oauth gem currently provides its own generators (rodauth:oauth:install and rodauth:oauth:views), but it would be nice if they didn't have to be duplicated.

In this article, I would like to show how to set each of these up in a Rails app that uses rodauth-rails. I'll be using Safari on macOS Ventura, and have iCloud Keychain sync enabled, which is a requirement for Apple passkeys.

Once I felt things were functioning well enough, I extracted the glue code into the rodauth-rails gem and added tests. I also included an install generator, which created the initial skeleton with sensible default configuration. A new Roda superclass provided a convenience configure method for loading the Rodauth plugin together with the rails feature.

FWIW I'm using rodauth and I like it: https://github.com/janko/rodauth-rails

My question is pretty much in the title. Is it possible to do Omniauth in a Rails API Only app? I've been looking into devise-token-auth and rodauth-rails. rodauth-rails has a tutorial for Omniauth (https://github.com/janko/rodauth-rails/wiki/OmniAuth), but it is using a Rails monolith.

I didn't create it, it was created by Jeremy Evans, I just contribute to it occasionally ;). I created the Rails integration, because I wanted to bring it into the Rails ecosystem, and I recently started recording screencasts. So I'm biased in that sense :)

$/myapp> bundle info rodauth-rails * rodauth-rails (0.18.1) Summary: Provides Rails integration for Rodauth. Homepage: https://github.com/janko/rodauth-rails Path: /Users/shino/.rbenv/versions/3.0.0/lib/ruby/gems/3.0.0/gems/rodauth-rails-0.18.1

I don't know if you've seen, but I wrote a guide that shows an integration, which you can use for now. This is also what the official demo Rails app uses.
