SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill provides a robust framework for defining, loading, and managing asynchronous services within a Node.js application, ensuring proper lifecycle management, dependency resolution, and graceful shutdown.

Core Features & Use Cases

  • Service Definition: Define services using defineService with lifecycle management and resource cleanup registration.
  • Dependency Injection: Load services within other services using loadService, automatically handling initialization order and detecting circular dependencies.
  • Lifecycle Management: Manages service states (init, ready, stopping, stopped) and provides observable events for monitoring.
  • Graceful Shutdown: Ensures all registered cleanup functions are executed when the application shuts down.
  • Use Case: Build a microservice where a database service, a cache service, and an authentication service are defined and loaded, with automatic cleanup of connections upon shutdown.

Quick Start

Use the hile-core skill to define and load a simple asynchronous service that returns a greeting.

FAQPage Schema
How do I manage asynchronous services and dependencies in Node.js?

You can manage asynchronous services in Node.js by using a service container to handle service definition, dependency injection, and lifecycle orchestration. This framework resolves initialization order automatically and detects circular dependencies.

How does graceful shutdown work for Node.js async services?

Graceful shutdown for Node.js async services executes registered resource cleanup callbacks during the shutdown phase. The framework transitions service states to stopping and stopped, ensuring connections are properly closed.

What is the best way to handle dependency injection for microservices with automatic cleanup?

The best way to handle dependency injection for microservices is using a service container that loads services within other services, automatically managing initialization order and registering cleanup functions for connection disposal upon shutdown.

Can I set timeout configurations for service startup and shutdown operations?

Yes, you can set timeout configurations for both startup and shutdown operations. This ensures that asynchronous service initialization and graceful shutdown resource cleanup processes do not hang indefinitely.

How do I detect circular dependencies when loading async services?

You detect circular dependencies when loading async services by utilizing a service container that automatically analyzes the dependency graph during the loadService phase, preventing infinite loops.

Why does service lifecycle management require observable events for monitoring?

Service lifecycle management requires observable events for monitoring because it tracks state transitions like init, ready, stopping, and stopped, allowing applications to react correctly to asynchronous service availability and shutdown phases.
