RABL (Ruby API Builder Language) is a Ruby templating system for Rails and Padrino that generates JSON, XML, MessagePack, PList, and BSON API responses. It provides an expressive view-layer DSL for building API representations that don't match database schemas directly.

Use cases

• generate custom JSON API responses in Rails
• serialize ActiveRecord objects with renamed or aliased attributes
• render partial templates to reduce duplication in API views
• conditionally include nodes in API output
• build nested API representations from model associations
• output MessagePack or BSON instead of JSON

When to choose

• you need complex JSON shapes that don't match your database schema
• you want API representation logic kept in the view layer per MVC
• you use Rails or Padrino and need multiple serialization formats

When to avoid

• simple APIs where ActiveRecord's to_ suffices
• non-Ruby stacks or frameworks without RABL integration
• projects preferring serializer gems like active_model_serializers or jbuilder
