gracy
Gracy is a zero-dependency library that provides a simple way to execute custom function before a Node.js process exits. It helps you ensure that your applications perform cleanup tasks, gracefully close resources, and maintain data integrity during (un)expected shutdowns or terminations.
pnpm i -E gracy
import { onExit } from 'gracy'
onExit(
{ logger: pinoInstance },
async () => {
closeHttpServer()
await closeDatabaseConnection()
}
)
The onExit function accepts an configuration object as its first argument. The following options are available:
| Name | Default value | Description |
|---|---|---|
logger | Logger to use. You should use libraries for structured logging such as pino, but you can also use the built-in console object. Set to false to disable logging. | |
events | ['uncaughtException', 'unhandledRejection'] | Events to listen to. Triggering these events will cause the process to exit with code 1. |
signals | ['SIGTERM', 'SIGINT'] | Signals to listen to. Triggering these signals will cause the process to exit with code 0. |
