SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you avoid exception-driven control flow by modeling outcomes as explicit values, so error handling stays predictable and composable.

Core Features & Use Cases

  • Result<T> for explicit outcomes: Represent success as { ok: true; value: T } and failure as { ok: false; errors: AppError[] }.
  • Railway-oriented pipelines: Chain transformations and validations with then/map/ensure (sync), andThen/mapAsync (async), or fluent ResultChain.
  • Async safety and ergonomics: Build a full async pipeline that resolves once at the end, using ResultAsync with .andThen() and .unwrap()/.toResult().
  • Maybe↔Result bridging: Convert between Maybe<T> and Result<T> with consistent failure semantics.

Quick Start

Use the Result primitives to implement a validated data-flow that returns either a typed success value or a structured list of AppError instances.

FAQPage Schema
How do I handle async errors in TypeScript without try/catch?

Handle async errors by modeling operation outcomes as explicit ResultAsync values with .andThen() chaining, resolving pipelines once at the end via .unwrap() to avoid try/catch blocks entirely.

What is the Result pattern and railway oriented programming in TypeScript?

The Result pattern represents outcomes as explicit values like { ok: true, value: T }, while railway oriented programming chains these transformations to keep success and failure flows predictable and composable.

How do I aggregate multiple validation errors in a TypeScript pipeline?

Aggregate validation errors by chaining steps with ResultChain or Result<T>, which models failures as { ok: false, errors: AppError[] } to collect structured AppError instances across multiple failing steps.

Can I convert between Maybe<T> and Result<T> in TypeScript?

Yes, you can convert between Maybe<T> and Result<T> using the provided Maybe↔Result bridge APIs, maintaining consistent failure semantics when transitioning between optional and explicit outcome values.

Does this TypeScript Result pattern work for domain logic and service orchestration?

Yes, the Result pattern applies to TypeScript domain logic and async service orchestration, providing deterministic pipelines and explicit error data accessors for predictable success and failure flows.
