Roar is a Ruby framework for parsing and rendering REST API documents using representers, supporting JSON, JSON-HAL, and XML formats. Its bi-directional representers let you both render representations from Ruby objects and parse incoming documents to update them, making it useful for API servers and clients alike.

Use cases

• render JSON API responses from Ruby models
• parse incoming REST documents into Ruby objects
• build hypermedia APIs with HAL-JSON links
• serialize models to XML for legacy clients
• build API clients that consume hypermedia
• define reusable API document structures with decorators

When to choose

• you need bi-directional serialization for REST documents in Ruby
• you want hypermedia support like HAL-JSON or JSON API
• you need a framework-agnostic layer that works with Rails, Sinatra, or Hanami

When to avoid

• you need a full REST framework with routing and controllers
• your project requires actively maintained dependencies with frequent releases
• you only need simple JSON serialization without hypermedia
