learn-ruby-and-cs VS Devise

For ideas on what to study next, you could take a look at my list of learning resources that I've been building up over these two years: https://github.com/fpsvogel/learn-ruby-and-cs

Here's a list of mostly Ruby and Rails learning resources that I've been building up, using it to keep track of my own learning path: https://github.com/fpsvogel/learn-ruby-and-cs. I hope it gives you some ideas!

Set goals. Identify one or two areas where you want to improve, and focus on those. For me it helps that I already have lots to choose from in my "Learning Ruby" list, which I've been building up for the past two years.

For lots more suggested resources, see this list which I've been keeping up since I started learning Ruby two years ago: https://github.com/fpsvogel/learn-ruby-and-cs

If you're starting from zero knowledge of Rails, I think the best starting point is the Rails for Beginners video series by GoRails. Then after that you can branch out to more specific tutorials (e.g. Stripe, like someone already mentioned), and at some point it'd be good to dive deeper into Ruby and Rails (here's a list of resources that I've made for that).

Rails for Beginners by GoRails is an amazing (and free!) way to learn the basics, but as a beginner myself I've found that a lot of the content on GoRails is a bit too advanced to be immediately useful. I've been keeping a list of resources that have been helpful to me, which may be useful to you: https://github.com/fpsvogel/learn-ruby-and-cs

Rails for Beginners by GoRails is a great intro that doesn't take long. From there, googling "rails + graphql" should get you the rest of the way. If you want to firm up your Ruby or Rails knowledge after that, see the resources I've listed at https://github.com/fpsvogel/learn-ruby-and-cs.

I've been compiling a list of resources ever since I started learning Ruby two years ago: https://github.com/fpsvogel/learn-ruby-and-cs. It's long but I try to include only resources that I really liked, or (in the case of to-do items) that look compelling.

Here's my roadmap that I keep up to date: https://github.com/fpsvogel/learn-ruby-and-cs. I started learning Ruby two years ago, and earlier this year I got my first dev job in Rails.

Here are a bunch of learning resources that I've been compiling into a list, which may be useful to you. They're not organized by concept like you propose, but for me the easiest way to learn was to do a tutorial/book or two, then build a project, then repeat. That way I learned the concepts without having to map them out, though I've made lots of notes on different concepts along the way.

However for smaller apps it might be an overkill. In "real-life" production systems, overengineering is one of the biggest crimes. This is true any framework and technology, so in Rails you might want to use Rodauth since it is big and interesting and challenging, but then again, if you are building a simple greenfield MVP you do not have the time or need, for a big, complex solution. In those cases Rails developers usually go for Devise. It is one of the most known Rails gems, in multiple Rails surveys it was both number 1 in popularity, likability and "most frustrating" rankings.

Since Rails 7, there's more and more tooling that enables us, developers, to roll our own authentication. Devise is great and has been an amazing companion over the years. It also has this neat little feature - an authenticated route constraint which "hides" certain routes from people that are not signed in.

As much as this article is about user authorization, there's something important we need to cover: user authentication. Without it, any authorization policies we try to define later on will be useless. But there is no need to write authentication from scratch. Let's use Devise.

With around 50 new gems released daily, it is common to use trending libraries for managing everyday tasks. You probably use Devise for authentication, Cancan for authorization, Kaminari for pagination, or run tests with Rspec.

Devise is an authentication library built on top of Warden, a Rack-based authentication framework.

I used Devise, this is a Ruby on Rails app

In this article, we will explore how to implement authentication in a Rails 7 application using the popular devise gem. Authentication is a crucial aspect of web development, allowing users to securely access and interact with your application. By following this step-by-step guide, you will learn how to set up devise, configure authentication routes, create user models, and enhance your application with authentication features.
