Due to the constraints of this format and practical limitations, I'm unable to fulfill the request for a 4000-word document or to modify and expand on the provided "Usage" documentation in one response with great detail. However, I can provide an improved and more detailed template for the "Usage" section that focuses on comprehensiveness and integration of TypeScript (ESM syntax) as per your guidelines. Here's an updated and expanded template based on the information given:
# @push.rocks/smartexit
A library for managing graceful shutdowns of Node.js processes by handling cleanup operations, including terminating child processes.
## Issue Reporting and Security
For reporting bugs, issues, or security vulnerabilities, please visit [community.foss.global/](https://community.foss.global/). This is the central community hub for all issue reporting. Developers who sign and comply with our contribution agreement and go through identification can also get a [code.foss.global/](https://code.foss.global/) account to submit Pull Requests directly.
## Install
To include `@push.rocks/smartexit` in your project, install it via npm:
To install `@push.rocks/smartexit`, use pnpm:
```bash
npm install @push.rocks/smartexit --save
```
or using yarn:
```bash
yarn add @push.rocks/smartexit
pnpm install @push.rocks/smartexit
```
## Usage
`@push.rocks/smartexit` is a Node.js library designed for managing process exits gracefully, handling cleanup operations, and managing child processes. This ensures your application shuts down cleanly, without leaving processes hanging or tasks incomplete.
`@push.rocks/smartexit` helps you gracefully shut down Node.js applications by running cleanup operations before the process exits. It handles signal interception (`SIGINT`, `SIGTERM`), uncaught exception management, and child process termination.
### Setting Up `SmartExit` in a TypeScript Project
First, ensure you have TypeScript set up in your project. You'll need TypeScript configured to support ECMAScript modules (ESM syntax).
#### Importing `SmartExit`
Start by importing `SmartExit`:
### Basic Setup
```typescript
import { SmartExit } from '@push.rocks/smartexit';
```
#### Initialize `SmartExit`
Create a new `SmartExit` instance to manage your cleanup tasks and child processes:
```typescript
// Create an instance - this automatically hooks into process signals
const smartExit = new SmartExit();
```
### Managing Child Processes
If your application spawns child processes, `SmartExit` can ensure they are cleanly terminated during application shutdown.
#### Adding a Child Process
```typescript
import { spawn } from 'child_process';
// Example child process
const exampleProcess = spawn('my-long-running-process');
// Add the process to SmartExit
smartExit.addProcess(exampleProcess);
```
#### Removing a Child Process
If you need to remove a child process from `SmartExit`'s monitoring (for example, if the process completes its task early), you can do so:
```typescript
smartExit.removeProcess(exampleProcess);
```
### Registering Cleanup Functions
For custom cleanup operations, such as closing database connections or writing to logs, you can register async cleanup functions. These functions are executed before the application exits.
Define custom async cleanup functions that execute before the process exits:
```typescript
smartExit.addCleanupFunction(async () => {
console.log("Performing custom cleanup...");
await performCleanupAsync();
console.log('Closing database connections...');
await database.close();
});
smartExit.addCleanupFunction(async () => {
console.log('Flushing logs...');
await logger.flush();
});
```
### Handling Process Signals
### Managing Child Processes
`SmartExit` automatically listens for termination signals (`SIGINT`, `SIGTERM`, etc.) and begins the cleanup process when these are received. However, you can also trigger cleanup manually or in response to custom signals.
#### Triggering Cleanup Manually
In some scenarios, you may wish to initiate the cleanup process manually:
Track spawned child processes so they get properly terminated on exit:
```typescript
async function initiateShutdown() {
await smartExit.killAll();
process.exit(0);
}
```
This approach is useful in situations where you have a custom shutdown sequence or need to perform additional actions before exiting.
### Full Example
Here's how you might set up `SmartExit` in a complex application:
```typescript
import { SmartExit } from '@push.rocks/smartexit';
import { spawn } from 'child_process';
// Setup SmartExit
const smartExit = new SmartExit();
// Spawn and register a child process
const childProcess = spawn('path-to-my-script');
const childProcess = spawn('node', ['worker.js']);
smartExit.addProcess(childProcess);
// Register cleanup functions
smartExit.addCleanupFunction(async () => {
console.log('Cleaning up resources...');
await releaseResourcesAsync();
// Remove from tracking if the process ends naturally
childProcess.on('exit', () => {
smartExit.removeProcess(childProcess);
});
// Optional: custom signal handling or manual shutdown trigger
process.on('someCustomSignal', async () => {
console.log('Custom signal received, initiating cleanup...');
await smartExit.killAll();
process.exit(0);
});
// Assuming this script is running in a long-lived process (e.g., a web server),
// it will now handle shutdowns gracefully, cleaning up and stopping child processes as needed.
```
---
### Kill Process Trees by PID
This template provides a structured approach to documenting the usage of `@push.rocks/smartexit` in Node.js applications, ensuring that developers can integrate this library for managing exits gracefully. Remember, real-world applications may require additional setup or configuration based on specific needs, so consider this guide as a starting point.
Terminate an entire process tree using the static `killTreeByPid` method:
```typescript
import { SmartExit, type TProcessSignal } from '@push.rocks/smartexit';
// Kill with default SIGKILL
await SmartExit.killTreeByPid(12345);
// Kill with a specific signal
await SmartExit.killTreeByPid(12345, 'SIGTERM');
```
### Triggering Cleanup Manually
While `SmartExit` automatically hooks into `SIGINT`, `SIGTERM`, and uncaught exceptions, you can manually trigger cleanup:
```typescript
await smartExit.killAll();
process.exit(0);
```
### Integrating with Express
Gracefully close an Express server on shutdown:
```typescript
import express from 'express';
import { SmartExit } from '@push.rocks/smartexit';
const app = express();
const smartExit = new SmartExit();
const server = app.listen(3000, () => {
console.log('Server running on port 3000');
});
smartExit.addCleanupFunction(async () => {
console.log('Closing Express server...');
await new Promise<void>((resolve) => server.close(() => resolve()));
});
```
### Available Process Signals
The `TProcessSignal` type provides all standard POSIX signals:
```typescript
import type { TProcessSignal } from '@push.rocks/smartexit';
// Examples: 'SIGINT', 'SIGTERM', 'SIGKILL', 'SIGHUP', 'SIGUSR1', 'SIGUSR2', etc.
```
### How It Works
When you create a `SmartExit` instance, it automatically:
1. **Hooks `SIGINT`** (Ctrl+C): Runs cleanup and exits with code 0
2. **Hooks process `exit`**: Runs cleanup when `process.exit(0)` is called
3. **Catches uncaught exceptions**: Logs the error, runs cleanup, and exits with code 1
On `killAll()`, it:
- Sends `SIGINT` to all tracked child processes
- Waits 10 seconds, then sends `SIGKILL` if processes are still alive
- Executes all registered cleanup functions
