Virtus
A Ruby library for defining attributes with type coercion, default values, and embedded objects on plain Ruby objects.
What is Virtus?
Virtus is a Ruby library that adds attribute definitions with type coercion and default values to plain Ruby objects. It solves the problem of manually handling data conversion and validation by allowing developers to define typed attributes that automatically coerce input values, such as converting strings to integers or hashes to nested objects. This makes it easier to work with external data sources like web parameters or JSON APIs.
Ruby developers building applications that require structured data handling, such as web APIs, domain models, or value objects, especially those needing type-safe attribute assignment and coercion.
Developers choose Virtus for its simplicity and flexibility in adding attribute management to any Ruby object without the overhead of a full ORM. Its support for embedded objects, collections, and custom coercions provides a powerful yet lightweight solution for data mapping and validation.
