SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Simplifies error handling and propagation in TypeScript backend/domain logic, ensuring predictable outcomes with the Result<T, E> type.

Core Features & Use Cases

  • Error Discipline: Encapsulates business logic within Result<T, E> for reliable error handling, avoiding exceptions and propagation at the transport boundary.
  • Domain Layer: Framework-pure domain/services logic returns Result, not exceptions, allowing for consistent failure handling.
  • Transport Boundary: Translates Result.error into a transport exception once at the boundary.
  • Error Type Management: Discriminated union error types are clearly defined, with new variants affecting multiple components for consistency.
  • Use Case: When implementing a backend service, this skill helps enforce a single point of error transformation at the transport layer, preventing errors from propagating deeper into the codebase.

Quick Start

Integrate 'result-pattern' into your TypeScript domain logic by defining Result types and using the 'ok' and 'err' functions to handle successful and failed outcomes, respectively.

Frequently Asked Questions about result-pattern

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is the Result type pattern for TypeScript error handling?▼

The Result type pattern encapsulates business logic outcomes in `Result<T, E>` objects, replacing exceptions with predictable success or failure states for consistent domain logic execution.

How do I handle errors at the transport boundary in TypeScript domain services?▼

You handle errors at the transport boundary by enforcing a single-point transformation, translating `Result.error` values into transport exceptions exactly once before sending responses.

How do I implement a Result type for domain logic without external libraries?▼

Implement a Result type by defining discriminated union error variants and using `ok` and `err` functions to return successful or failed outcomes directly from your framework-pure domain services layer.

When should I use the Result pattern instead of throwing exceptions in TypeScript?▼

Use the Result pattern for backend domain and services layers to ensure predictable outcomes, preventing unpredictable exception propagation and enforcing consistent failure handling across components.

Do I need any external dependencies to use a Result type in TypeScript?▼

No external dependencies are required. The Result type system operates entirely within your TypeScript codebase, requiring no additional libraries to implement error discipline.

How does the Result pattern manage discriminated union error types?▼

The Result pattern manages errors by clearly defining discriminated union error types, ensuring that introducing new error variants consistently affects all related components for type safety.
