Ruby: Setting up a Ruby project

This documentation is part of the Getting started guide. View the full guide here: Getting started with Ruby on Rails.

Starting a new Ruby project is straightforward. Follow these steps to get going:

1. First, make sure you have the latest version of Ruby installed on your system. You can verify this by executing the following command in your terminal:

   asdf install ruby latest \
     && asdf global ruby latest
   

   If you have not installed asdf yet, you will need to do so before proceeding. Please refer to the official asdf documentation for detailed installation instructions.

   Alternatively, you can use Stackhero Code-Hero, an online development solution where all necessary tools are pre-installed. This platform allows you to start coding immediately without manual installation.

2. Next, install Rails. Rails is distributed as a RubyGem which makes installation straightforward:

   gem install rails
   

3. Then, create a new Rails application named my_app and specify the Ruby version using these commands:

   rails new my_app
   cd my_app
   asdf local ruby latest
   

4. To launch the Rails server, run the following command:

   bin/rails server

These steps create a new Ruby project while setting the appropriate Ruby version. This lays a solid foundation for your application development.

Important: When executing the rails new command, a local Git repository is automatically created for your Ruby project. However, it is not yet linked to a remote version control service.

For proper version control and data safety, you are encouraged to connect your project to a hosting service such as GitLab, GitHub, or Bitbucket.

If you need a repository hosting service, Stackhero offers a GitLab cloud service that can be set up in just 2 minutes.

Special case with Stackhero Code-Hero

When using an online development solution like Stackhero Code-Hero, you need to adjust your config/environments/development.rb file. Add the following configuration near the final end keyword. Replace <XXXXXX>.stackhero-network.com with your actual server hostname:

config.hosts << "<XXXXXX>.stackhero-network.com"

Finally, start the Rails server with this command:

bin/rails server -b 0.0.0.0

This command ensures that the Rails server is accessible from any IP address, which is especially useful when working remotely via Stackhero Code-Hero.
