Nodejs promise code#

The listener callback function is invoked with the exit code specified eitherīy the process.exitCode property, or the exitCode argument passed to the There is no way to prevent the exiting of the event loop at this point, and onceĪll 'exit' listeners have finished running the Node.js process will terminate. The Node.js event loop no longer having any additional work to perform.The primitive can be used to clear the Timeout.The primitive can only be used in the same thread where the timeout was created.

• The process.exit() method being called explicitly Returns: a number that can be used to reference this timeout Coerce a Timeout to a primitive.

The 'exit' event is emitted when the Node.js process is about to exit as a Process beforeExit event with code: 0 // Process exit event with code: 0 Event: 'disconnect' # Prints: // This message is displayed first. Process beforeExit event with code: 0 // Process exit event with code: 0 const process = require( 'node:process') log( 'This message is displayed first.') log( 'Process exit event with code: ', code) Ĭonsole. log( 'Process beforeExit event with code: ', code) Ĭonsole. import process from 'node:process' Ĭonsole. Unless the intention is to schedule additional work. The 'beforeExit' should not be used as an alternative to the 'exit' event

Termination, such as calling process.exit() or uncaught exceptions. The 'beforeExit' event is not emitted for conditions causing explicit Process.exitCode passed as the only argument. The listener callback function is invoked with the value of There is no work scheduled, but a listener registered on the 'beforeExit'Įvent can make asynchronous calls, and thereby cause the Node.js process to Normally, the Node.js process will exit when The 'beforeExit' event is emitted when Node.js empties its event loop and has process.hasUncaughtExceptionCaptureCallback().Warning: Using 'uncaughtException' correctly.
