Essential building-blocks for functional & safe TypeScript code

Boxed provides essential building-blocks (in the form of types and functions) so that you can write functional, safe TypeScript code.

Design principles

  • Provide utility types that make data-manipulation and storage easier
  • Immutable (all provided types are)
  • Give a good development experience (chaining API, reliable types)
  • Simple interoperability (you can convert back and forth to JS native types)
  • Compatibility with ts-pattern (using patterns we provide).

What's in the box?

  • Option<Value>
  • Result<Ok, Error>
  • Future<Value>
  • AsyncData<Value>
  • Lazy<Value>
  • Some utils like Deferred, Dict & Array
