Rails offers the ability to set up a different database per software life cycle environment. In this section, you will connect the demo application to a PostgreSQL database. Your new Rails application needs a database to store the messages to be shown to authenticated users. With the Rails application successfully created, it will be connected to a database in the next section. This will stop the running server, and the application will no longer be accessible in the browser.

To see the application, navigate to in your browser, and you will be greeted with Rails' default welcome page. The command above fires up a Puma server, which is Rails' default web server, and serves the Rails application on port 3000. To create a new Rails application, open up a terminal window on your machine and run the following command: One such command is the new command, used to generate a new Rails application. Rails provides a set of commands that make building web applications an easy experience. This demo application will contain messages that should be visible to only authenticated users. In this section, you will create a new Rails application. Deploying the Rails application to Koyeb.
Integrate Authentication to the application with Devise.The steps to implementing authentication in a Rails application and deploying it to Production on Koyeb include: A Koyeb account to deploy the demo application.An ElephantSQL account to get a PostgreSQL database.This tutorial uses version 13 of PostgreSQL. PostgreSQL installed on your local development machine.Yarn package manager installed on your local development machine.Node.js 10.17 or higher installed on your local development machine.This demo application in this tutorial is built with Rails 6.1 Ruby on Rails framework installed on your local development machine.This tutorial uses version 2.6.6 of Ruby. Ruby programming language installed on your local development machine.To successfully follow this tutorial, you need the following: With Koyeb's git-driven deployment, all changes you make to your application will be automatically built and promoted once the build and necessary healthchecks are complete. We will deploy this application on Koyeb and enjoy the platform's built-in autoscaling, automatic HTTPS, global load balancing, and more.

In this tutorial, you will learn how to implement authentication in a Rails application by using Devise, an authentication solution for Rails.

Still, there are cases when you may need to restart the server, but may face troubles trying to stop it, especially if you have your project server is started as a demon. One of the great things about developing Rails applications is that you don’t have to restart the server to test every change that you have made in your code.
