This post provides a curated list of books to learn to code in Ruby and build web applications with Rails. It also gives a step-by-step path you can follow to learn enough before moving to the next step. If you ever wanted to learn to program but didn’t know where to start, this post is for you.

Rails is great for building web apps. But it can be quite overwhelming if you don’t know how web applications work. In this series of articles, we’ll build a simple but complete app in plain Ruby without Rails, to get a deeper understanding and appreciation of everything Rails does for us.

This is the day when you fall in love with Hotwire. We’re going to build a simple counter. But we’re not going to build it once and be done with it. Instead, we’ll build and progressively enhance it with all three frameworks in Hotwire: Turbo Drive, Turbo Frames, and Turbo Streams.

Although Hotwire is closely tied to Ruby on Rails, you might be surprised to know that you don’t really need Rails to learn, play, and experiment with Hotwire. In this article, I will show you how a simple static website can use Turbo Drive and Frames to make it more dynamic and responsive.

The router is the entry point of your Rails application. It acts as the gatekeeper for all incoming HTTP requests, inspecting and sending them to a controller action; even filtering and rejecting them if necessary. In this article, we’ll do a deep dive into the Rails Router to understand it better.

Hotwire, which stands for HTML Over the Wire, provides a different way to build modern web applications without using too much JavaScript. This article provides a quick introduction to Hotwire and its component frameworks, such as Turbo Drive, Frames, and Streams.

Polymorphic associations in Rails allow a single model to belong to multiple models. This article covers them in-depth. We’ll start with understanding the concept of polymorphism, learn what a polymorphic association is, why we need them, how they work, and how to use them in your Rails application.

Concerns are an important concept in Rails that can be confusing to understand for those new to Rails as well as seasoned practitioners. This post explains why we need concerns, how they work, and how to use them to simplify your code.

In this article, I will try to explain pretty much everything that you need to know about Rack as a Ruby and Rails developer. It covers everything from the basics to more advanced stuff such as middleware and writing your custom middleware.

This post explains how to build a to-do list using the new Hotwire and Stimulus frameworks from Basecamp. We will start with a new Rails app from scratch and learn about these frameworks as we build our list.

Rails provides a `Configurable` concern that lets you add configuration options on classes.

Metaprogramming in Ruby enables you to produce elegant, clean, and beautiful programs as well as unreadable, complex code that’s not maintainable. This book will teach you the powerful metaprogramming concepts in Ruby, and how to use them judiciously.
