What problem does it solve?
Developing scalable and maintainable Sinatra applications requires effective strategies for routing, middleware integration, error handling, and overall application organization. Without these, applications can become unwieldy and difficult to extend.
Core Features & Use Cases
- Advanced Routing: Implement modular applications, namespaces, route conditions, and content negotiation for flexible API and web development.
- Middleware Composition: Learn custom middleware development, proper ordering, and conditional middleware for a robust request/response pipeline.
- Error Handling Patterns: Apply comprehensive strategies for specific exceptions, HTTP status codes, and a catch-all error handler to ensure graceful failure.
- Use Case: A developer is building a complex Sinatra API with multiple versions and admin sections. This Skill guides them in structuring the application using modular controllers and namespaces, implementing custom middleware for authentication, and setting up robust error handling, ensuring a clean and scalable codebase.
Quick Start
Basic Sinatra route
get '/' do
'Hello World'
end
Modular application example
app/controllers/users_controller.rb
class UsersController < BaseController
get '/' do
users = User.all
json_response(users.map(&:to_hash))
end
end
config.ru
map '/users' do
run UsersController
end
