SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Go applications frequently deal with nullable values and nested error handling. This Skill introduces samber/mo monads (Option, Result, Either) and pipeline patterns to express these concerns in a type-safe, composable way.

Core Features & Use Cases

Introduces core monads (Option, Result, Either) with idiomatic usage and examples.
Shows how to compose transformations with direct method chaining and sub-packages for type-changing steps.
Demonstrates Do notation and pipe-based pipelines to simplify multi-step data processing.

Quick Start

Create a small sample that demonstrates composing Option, Result, and Either using mo in a Go module.

FAQPage Schema

How do I handle nullable values and nested error handling in Go?▼

Handle nullable values and nested error handling in Go using samber/mo monads like Option, Result, and Either to express these concerns in a type-safe, composable way. This approach replaces manual nil checks with structured functional pipelines.

What is the best way to compose multi-step data transformations in Go?▼

The best way to compose multi-step data transformations in Go is using Do notation and pipe-based pipelines with samber/mo. These patterns simplify complex processing chains by structuring type-changing maps and cross-package composability.

Can I use Go monads for type-changing transformations across different packages?▼

Yes, you can use Go monads for type-changing transformations across packages. The samber/mo library supports cross-package composability through direct method chaining and sub-packages, enabling robust pipeline construction in real-world projects.

How do Option and Result monads improve error flow in Go applications?▼

Option and Result monads improve Go error flow by modeling nullable values and errors as type-safe values. Instead of returning unstructured errors, they wrap outcomes in a composable container that standardizes how downstream functions process success or failure states.

Does functional programming with Go monads require external dependencies?▼

Functional programming with Go monads requires the samber/mo library as an external dependency. Once imported into your Go module, it provides the core Option, Result, and Either monad implementations needed to structure functional pipelines.

When should I not use functional programming patterns for Go error handling?▼

You should not use functional programming patterns for Go error handling when your project strictly prohibits external dependencies or when simple native error checks suffice. Monads add structural overhead that may be unnecessary for straightforward, non-composable logic.
