SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Dependency injection reduces tight coupling by centralizing service creation and resolution, enabling easy testing and scalable architecture in server-side code.

Core Features & Use Cases

  • Create services under apps/server/src/features/<feature> and annotate with @injectable to enable DI.
  • Register tokens in apps/server/src/di/tokens.ts and map token values to types.
  • Register and resolve services in apps/server/src/di/container.ts, and access them via resolve or DI getters.
  • Use constructor injection with @inject for dependencies to promote testability and modularity.
  • Leverage service lifecycles (Singleton/Transient) to control instance scope and state.

Quick Start

Register a service token, implement the service, register it in the container, and resolve it in a handler.

Frequently Asked Questions about dependency-injection-setup

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

FAQPage Schema
How do I set up dependency injection in a Node server using tsyringe?▼

You set up dependency injection by annotating services with @injectable, registering tokens in a central file, mapping those tokens in a container, and resolving them within handlers.

What problems does dependency injection solve in TypeScript server applications?▼

Dependency injection solves tight coupling by centralizing service creation and resolution, enabling easy testing with mocks and scalable architecture in server-side TypeScript code.

How do I inject mock dependencies when testing TypeScript services?▼

You test with mocks by using constructor injection with @inject for dependencies, which promotes modularity and allows you to easily substitute mock services during testing.

Can I control service lifecycles like Singleton and Transient with tsyringe?▼

Yes, you can leverage service lifecycles like Singleton and Transient to control instance scope and manage state across server modules when using tsyringe.

Does tsyringe work with constructor injection for Node server modules?▼

Yes, tsyringe supports constructor injection using @inject for dependencies, allowing you to wire registrations and resolve services directly within server handlers.
