# Changelog
|
||||||
|
|
||||||
|
## 2025-12-15 - 1.1.0 - feat(smartexit)
|
||||||
|
Add silent logging option, structured shutdown logs, and killAll return stats
|
||||||
|
|
||||||
|
- Introduce ISmartExitOptions with a silent flag to disable console logging
|
||||||
|
- Add internal log() helper and use a [smartexit] prefix for shutdown/error messages
|
||||||
|
- killAll() now returns Promise<{ processesKilled, cleanupFunctionsRan }> and tallies processes and cleanup functions run
|
||||||
|
- Constructor accepts options (backwards compatible) to configure behavior
|
||||||
|
- Documentation (readme.hints.md) updated with usage and example output
|
||||||
|
|
||||||
|

# SmartExit - Development Hints
|
||||||
|
|
||||||
|
## Logging System
|
||||||
|
|
||||||
|
The module uses consolidated logging with a `[smartexit]` prefix:
|
||||||
|
|
||||||
|
- **Default behavior**: Logs a single summary line on shutdown
|
||||||
|
- **Silent mode**: Pass `{ silent: true }` to constructor to disable all logging
|
||||||
|
|
||||||
|
### Example output
|
||||||
|
```
|
||||||
|
[smartexit] Shutdown complete: killed 3 child processes, ran 2 cleanup functions
|
||||||
|
```
|
||||||
|
|
||||||
|
### Usage
|
||||||
|
```typescript
|
||||||
|
// Default - logs summary
|
||||||
|
const smartExit = new SmartExit();
|
||||||
|
|
||||||
|
// Silent - no logging
|
||||||
|
const smartExit = new SmartExit({ silent: true });
|
||||||
|
```
|
||||||
|
|
||||||
|
## killAll() Return Value
|
||||||
|
|
||||||
|
The `killAll()` method returns stats about the cleanup:
|
||||||
|
```typescript
|
||||||
|
const { processesKilled, cleanupFunctionsRan } = await smartExit.killAll();
|
||||||
|
```

## Contribution
|
`@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.

We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
|
### Basic Setup
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
import { SmartExit } from '@push.rocks/smartexit';
|
||||||
|
|
||||||
## Contribution
|
// Create an instance - this automatically hooks into process signals
|
||||||
|
const smartExit = new SmartExit();
|
||||||
|
```

|
### Registering Cleanup Functions
|
||||||
|
|
||||||
For further information read the linked docs at the top of this readme.
|
Define custom async cleanup functions that execute before the process exits:
|
||||||
|
|
||||||
## Legal
|
```typescript
|
||||||
> MIT licensed | **©** [Task Venture Capital GmbH](https://task.vc)
|
smartExit.addCleanupFunction(async () => {
|
||||||
| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
|
console.log('Closing database connections...');
|
||||||
|
await database.close();
|
||||||
|
});
|
||||||
|
|
||||||
|
smartExit.addCleanupFunction(async () => {
|
||||||
|
console.log('Flushing logs...');
|
||||||
|
await logger.flush();
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Managing Child Processes
|
||||||
|
|
||||||
|
Track spawned child processes so they get properly terminated on exit:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
import { spawn } from 'child_process';
|
||||||
|
|
||||||
|
const childProcess = spawn('node', ['worker.js']);
|
||||||
|
smartExit.addProcess(childProcess);
|
||||||
|
|
||||||
|
// Remove from tracking if the process ends naturally
|
||||||
|
childProcess.on('exit', () => {
|
||||||
|
smartExit.removeProcess(childProcess);
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Kill Process Trees by PID
|
||||||
|
|
||||||
|
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
|
||||||
