Shutdown-Cleanup Module

The shutdown-cleanup module provides a structured approach for managing graceful shutdowns in Node.js applications. It supports phased shutdowns, signal-specific handlers, customizable error handling strategies, and custom exit codes, ensuring broad compatibility with LTS Node.js versions.

Features

• Phased Shutdown: Organizes shutdown logic into phases for orderly execution.
• Signal-Specific Handlers: Custom logic for specific signals without mandatory shutdown.
• Error Handling Strategy: Customizable handling of handler errors, including proper management of synchronous and asynchronous handlers to prevent unhandled promise rejections.
• Custom Exit Codes: Specify exit codes to indicate shutdown statuses.
• Graceful Shutdown with Timeout: Prevents indefinite hangs during shutdown. (See Developer Guide for details.)
• LTS Node.js Support: Compatible with LTS Node.js versions.
• Enhanced Flexibility: Supports handling of custom application events.
• TypeScript Support: Includes TypeScript definitions for ease of development.

Installation

npm install @hypercliq/shutdown-cleanup

Or using Yarn:

yarn add @hypercliq/shutdown-cleanup

Usage

To use shutdown-cleanup, import and utilize its functions within your application to manage shutdown logic effectively. Both synchronous and asynchronous handlers are supported.

import { registerHandler } from '@hypercliq/shutdown-cleanup'

// Asynchronous handler
registerHandler(async (signal) => {
  await performCleanup()
  console.log('Async cleanup completed')
})

// Synchronous handler
registerHandler((signal) => {
  performSyncCleanup()
  console.log('Sync cleanup completed')
})
