Create a new Rails application with various options

bash

# Basic app
rails new myapp

# API-only app
rails new myapp --api

# Skip specific components
rails new myapp --skip-test --skip-bundle

✅ Default database is SQLite, use --database for PostgreSQL/MySQL

💡 --api flag creates lightweight API-only app

🔍 --skip-test useful if using RSpec instead of Minitest

⚡ Use rails new --help to see all available options
