Ruby Routes is a flexible, high-performance routing library that can be used in various contexts beyond traditional web frameworks. Here are the key usage scenarios:
# Microservice with custom routing
require 'ruby_routes'
require 'rack'
router = RubyRoutes.draw do
get '/health', to: 'health#check'
get '/api/v1/users/:id', as: :user, to: 'users#show'
post '/api/v1/users', as: :create_user, to: 'users#create'
namespace :admin do
resources :users
resources :analytics
end
end
# Generate URLs programmatically
user_path = router.route_set.generate_path(:user, id: 123) # => "/api/v1/users/123"
create_user_path = router.route_set.generate_path(:create_user) # => "/api/v1/users"
# Rack application
class MyApp
def initialize(router)
@router = router
end
def call(env)
route = @router.route_set.match(env['REQUEST_METHOD'], env['PATH_INFO'])
# Handle routing logic
end
end# Route requests to different microservices
router = RubyRoutes.draw do
scope path: '/api/v1' do
get '/users/*path', to: 'proxy#users_service'
get '/orders/*path', to: 'proxy#orders_service'
get '/payments/*path', to: 'proxy#payments_service'
end
# Rate limiting routes (rate limiting logic would be implemented in the proxy handler)
get '/public/*path', to: 'proxy#public_api'
get '/premium/*path', to: 'proxy#premium_api'
end# Build your own web framework
class MyFramework
def initialize(&block)
@router = RubyRoutes.draw(&block)
end
def call(env)
route_info = @router.route_set.match(env['REQUEST_METHOD'], env['PATH_INFO'])
return [404, {}, ['Not Found']] unless route_info
controller_class = Object.const_get("#{route_info[:controller].capitalize}Controller")
controller = controller_class.new
response = controller.send(route_info[:action], route_info[:params])
[200, {'Content-Type' => 'application/json'}, [response.to_json]]
end
end
# Usage
app = MyFramework.new do
resources :users
resources :posts
end# Route CLI commands to handlers
class CLIRouter
def initialize
@router = RubyRoutes.draw do
get '/user/create', to: 'user#create'
get '/user/list', to: 'user#list'
get '/user/:id/show', to: 'user#show'

handler_class.new.send(route[:action], route[:params])
else

# Usage: ruby cli.rb user create --name John

end
end
# Usage

end- Fast routing - Handles high-frequency routing decisions
- 99.99% cache hit rate - Optimal for repeated patterns
- Zero memory leaks - Suitable for long-running processes
- Input validation - Built-in constraint system with ReDoS protection
- Thread safety - Safe for concurrent applications
- Secure constraints - Type-safe constraint system without code execution
- Pattern matching - Complex routing patterns
- Constraint system - Validate parameters before processing
- Named routes - Generate URLs/paths programmatically
- Rails-like DSL - Familiar syntax
- Comprehensive documentation - Easy to learn and implement
- No dependencies - Lightweight and portable
Ruby Routes transforms from a simple web routing library into a versatile pattern-matching and request-routing engine suitable for any application that needs to route requests, commands, messages, or data based on structured patterns.
