SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Designing scalable applications with explicit, maintainable dependency graphs can be complex. This Skill provides proven patterns and examples for building and composing Effect layers in TypeScript, making dependencies and resource lifecycles clear and testable.

Core Features & Use Cases

Layer-based architecture patterns for combining dependencies and outputs using Layer.merge, Layer.provide, and Layer.effect.
Resource management examples with Layer.scoped and acquisition/release semantics.
Guidance on layering infrastructure, domain, and application concerns to improve testing and maintainability.

Quick Start

Define a few sample layers (for example Config and Logger), combine them with Layer.merge, and then provide dependencies to build a runnable program. Replace the sample services with real implementations as you move from example to production.

FAQPage Schema

How do I design clean dependency layers in TypeScript using the Effect library?▼

You design clean dependency layers in TypeScript by using Effect's Layer APIs to structure, merge, and provide dependencies. This approach separates infrastructure, domain, and application concerns, making your dependency graphs explicit, testable, and maintainable.

What is the best way to manage resource lifecycles in Effect?▼

The best way to manage resource lifecycles in Effect is using Layer.scoped. It handles acquisition and release semantics automatically, ensuring resources are safely allocated and cleaned up when the layer is no longer needed.

How does Layer.merge combine dependencies in an Effect application?▼

Layer.merge combines multiple Effect layers into a single unified layer. It takes independent dependencies, like a Config layer and a Logger layer, and aggregates their outputs so they can be provided together across application boundaries.

Do I need prior knowledge of Effect to use layer design patterns?▼

Yes, you need prior knowledge of the Effect library and TypeScript typing. Designing these dependency layers requires understanding Layer APIs including Layer.succeed, Layer.effect, Layer.scoped, Layer.merge, and Layer.provide.

When should I use Layer.effect instead of Layer.succeed?▼

Use Layer.effect when creating a dependency requires an Effect workflow, such as reading configuration or performing asynchronous setup. Use Layer.succeed when you have a static, already-constructed service instance to provide directly.

How do I provide dependencies to build a runnable Effect program?▼

You provide dependencies to build a runnable Effect program by using Layer.provide. This feeds merged dependency layers into your application's main workflow, replacing sample or mock services with real production implementations at app boundaries.
