dry-validation is a Ruby library for data validation using type-safe schemas and composable rules. It supports input coercion, nested data, custom predicates, and detailed error messages.

Use cases

• validate request params in a ruby web app
• validate json payloads against a schema
• coerce and validate form input
• validate nested data structures in ruby
• add custom validation rules with error messages
• validate api input before processing

When to choose

• you need type-safe, composable validation schemas in Ruby
• you want input coercion plus validation in one step
• you need detailed, localized error messages for invalid data

When to avoid

• you only need simple presence checks and prefer minimal dependencies
• you are not working in Ruby
• you need database-level or ORM-integrated validation
