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.
