What it is

Ruby is a programming language designed to be pleasant to read and write. Rails, or Ruby on Rails, is a web framework built on it: it gives a new web app a database layer, routing, templates and tests from the start, and favors sensible conventions over configuration. GitHub, Shopify and Basecamp were built with it.

Ruby libraries are called gems; Bundler installs the ones a project needs from its Gemfile.

Why it’s here

  • Fast to build web apps. rails new gives you a working app in minutes.
  • Batteries included. Database migrations, background jobs, mail and tests are part of the framework.
  • Ruby itself. A good language for scripts and automation, too.

On CoreDesktop

CoreDesktop installs Ruby with mise rather than pacman: it installs the latest Ruby and makes it your default (mise use -g ruby@latest), then installs the Bundler and Rails gems. Each update updates mise, moves you to the newest Ruby, and runs gem update to update your gems, Rails included.

Start a new app with:

rails new myapp
