1.0.0

Major Changes

• 50bf63f: ## v1.0.0 — Core Foundation

  Initial release of @deessejs/errors, a function-based error handling library inspired by Python's error system.

  Added

  • error() function for defining error types with Standard Schema support
  • raise() function for throwing errors
  • Native throw syntax support
  • is() function for type checking with inheritance support
  • inherits option for single and multiple inheritance
  • .from() method for exception chaining
  • causes() function for chain traversal (most recent first)
  • err.fields namespace for user-defined data
  • Message templates with {field} placeholders
  • All error properties always defined (never undefined)
  • Standard Schema compliance for field definitions (Zod, Valibot, ArkType)

  TypeScript Support

  • Generic types: ErrorFactory<T>, ErrorInstance<T>
  • Full type inference with fields
  • No any — only generics and proper types
