JIT Compilers for Ruby and Rails: An Overview

A program is compiled at runtime using a different method from pre-execution compilation. This process is known as just-in-time compilation or dynamic translation.

But first: how does JIT compilation work?


Connect a Ruby on Rails App with React in a Monolith

More and more people are using Ruby on Rails to create a back-end API application for a front-end app. But what if you want to create a rich and functional interface with JavaScript and use Rails for the back-end, without having them in separate repositories?

Deploy Your Ruby on Rails App Using Capistrano

In this article, we will configure Capistrano in a Ruby on Rails application. We will then deploy the app to a cloud instance that runs Ubuntu as an operating system, independent of your hosting provider. You can use any cloud service, or even an on-premises server, to test or replicate the steps we'll take. Once we've deployed the app, we'll look briefly at how you can monitor your app's deployments using AppSignal. But first, you might ask: why should I use Capistrano in the first place?
