How to Set Up a Simple Ruby on Rails Application in 2025

Setting up a Ruby on Rails application is a straightforward process, even in 2025. With the latest Ruby on Rails version, you’ll enjoy a robust framework that simplifies the development process. In this article, we’ll walk you through the steps to set up a simple Rails application from scratch, optimized for modern development.

Prerequisites

Before you begin, ensure you have the following installed on your system:

  • Ruby (version 3.2 or later): Ruby on Rails runs on the Ruby programming language. Ensure you are using a version compatible with Rails 7, which you can check by running ruby -v.
  • Rails (version 7 or later): Rails is the framework. You can install it using the command gem install rails.
  • Node.js and Yarn: Rails requires a JavaScript runtime, which Node.js provides. Yarn is used for managing JavaScript dependencies.
  • Database (SQLite, PostgreSQL, etc.): SQLite is often used for development purposes, but you can choose other databases like PostgreSQL for production.

Step-by-Step Guide to Set Up Your Rails Application

Step 1: Install Rails

First, open your terminal and install Rails by running:

gem install rails

This command installs the latest version of Rails on your system.

Step 2: Create a New Rails Application

Once Rails is installed, create a new application. Open your terminal and run:

rails new myapp

Replace “myapp” with your desired application name. This command sets up a new Rails skeleton application with a default directory structure.

Step 3: Configure Your Database

Rails defaults to using SQLite. If you prefer PostgreSQL, update the config/database.yml file with your database credentials.

Step 4: Run Your Rails Server

After setting up the application and database, navigate to your application directory:

cd myapp

Then, run the Rails server with:

rails server

Visit http://localhost:3000 in your browser to see your Rails application in action!

Step 5: Explore Ruby on Rails Features

Now that your Rails application is running, consider exploring its features to build powerful applications:

Conclusion

Setting up a simple Ruby on Rails application is an essential skill for modern web developers. By following this guide, you’re now equipped to start developing robust web applications using the Rails framework. Continue learning and exploring Rails to unlock its full potential and keep your skills up-to-date with the latest in web development.
