Modulorails

Modulorails is the common base for the Ruby on Rails project at Modulotech.

It registers each application using it on the company's intranet, provides templates for the common configurations and defines common dependencies.

Add this line to your application's Gemfile:

gem 'modulorails'

And then execute:

$ bundle install

To work the gem needs to be configured. Add an initializer config/modulorails.rb:

Modulorails.configure do |config|
  config.name 'The usual name of the application'
  config.main_developer 'The email of the main developer/maintainer of the application'
  config.project_manager 'The email of the project manager of the application'
  config.endpoint 'The url to the intranet'
  config.api_key 'The API key'
end

Modulorails automatically generates a .devcontainer/ configuration for VS Code and compatible IDEs:

• Dockerfile for the development container
• compose.yml with database, Redis, and mailcatcher services
• devcontainer.json for VS Code integration

Two helper scripts are provided in bin/:

• bin/dc - Wrapper for docker compose commands targeting the devcontainer
• bin/dcr - Wrapper for docker compose run with proper TTY and Git configuration

Usage:

bin/dc up -d          # Start services in background
bin/dc logs -f app    # Follow app logs
bin/dcr rails console # Run Rails console in container
bin/dcr rspec         # Run tests in container

Modulorails can configure your devcontainer for efficient use with Claude Code:

• Persistent bash history across container restarts
• Claude Code configuration volume
• Firewall initialization script

Modulorails detects and supports the Bun JavaScript runtime. When bun.config.js is present, the devcontainer will include appropriate JS and CSS build services.

• RubocopGenerator - Configures .rubocop.yml with Modulotech standards
• BundlerauditGenerator - Sets up bundler-audit for security checks
• GithooksGenerator - Installs git hooks for automated checks
• HealthCheckGenerator - Configures the health_check gem
• SidekiqGenerator - Adds Sidekiq background job processing

The following features are deprecated and will be removed in version 2.0:

• config.staging_url
• config.review_base_url
• config.production_url
• config.no_auto_update

• Modulorails::BaseService#log - Use Rails.logger.debug directly
• Modulorails::LogsForMethodService - Use Rails.logger.debug directly

The following generators are deprecated and will be moved to Moduloproject 3.0:

• Modulorails::DockerGenerator (and all sub-generators)
• Modulorails::GitlabciGenerator
• Modulorails::ClaudeCodeGenerator
• Modulorails::ModuloprojectGenerator
• Modulorails::SidekiqGenerator
• Modulorails::SelfUpdateGenerator (will be removed entirely)

There are tests in spec. To run tests:

• Build Docker images using docker compose build.
• You can run tests on all supported Ruby versions using docker compose up.
• Or you can run test on a specific Ruby version using one of the following commands:
  • Ruby 2.5: docker compose run ruby25
  • Ruby 2.6: docker compose run ruby26
  • Ruby 2.7: docker compose run ruby27
  • Ruby 3.0: docker compose run ruby30
  • Ruby 3.1: docker compose run ruby31

Appraisal is used to test the gem against many supported Rails versions:

• Rails 5.2, 6.0 and 6.1 on Ruby 2.5 and 2.6.
• Rails 5.2, 6.0, 6.1 and 7.0 on Ruby 2.7, 3.0 and 3.1.
