Services Module

This file defines the Services class, which is responsible for managing and running all services decorated with the @Service decorator in the @sodacore/core library. It handles the initialization, starting, and stopping of all registered services.

---

Features

• Service Discovery: Finds all registered services in the global Registry that are decorated as services.
• Lifecycle Management: Provides methods to initialize, start, and stop all services.
• Logging: Logs the status and count of services during each lifecycle phase.

---

Usage

import Services from './module/services';

const services = new Services(config);
await services.init();
await services.start();
// ... later
await services.stop();

API

Properties

• services: BaseService[] List of all discovered and managed service instances.

Methods

async init(): Promise<void>

Initializes the services module:

• Discovers all registered services by filtering modules in the Registry with the type metadata set to 'service'.
• Calls the init() method on each service instance.
• Logs the number of initialized services.

async start(): Promise<void>

Starts all services by calling their start() method and logs the number of started services.

async stop(): Promise<void>

Stops all services by calling their stop() method and logs the number of stopped services.

How It Works

1. Service Discovery:

   • Filters all modules in the Registry to find those with the type metadata set to 'service'.

2. Lifecycle:

   • init() initializes all discovered services.
   • start() starts all initialized services.
   • stop() stops all running services.

3. Logging:

   • Each lifecycle method logs the action and the number of affected services.

Notes

• Services must extend BaseService and be decorated with the @Service decorator to be managed by this module.
• The module ensures all services are properly initialized, started, and stopped in a consistent manner.
