Node.js - exit from program (programmatically)

In this article, we would like to show you how to exit from program in Node.js.

Quick solution:

xxxxxxxxxx

process.exit(0);

Note:

Default value of the exit code is 0 and means success.

The process module provides exit() method that allows you to programmatically exit from a Node.js program.

When Node.js executes the method, the process is immediately forced to terminate, which means that any callback function that's pending, any request still being sent, processes writing etc. is going to be ungracefully terminated right away.

You can pass an integer that signals the operating system the exit code:

xxxxxxxxxx

process.exit(0);

The default value of the exit code is 0 and means success.

Any different exit codes have different meaning which you might want to use in your system.

Example:

xxxxxxxxxx

process.exit(1);

Meaning:

Uncaught Fatal Exception: There was an uncaught exception, and it was not handled by a domain or an 'uncaughtException' event handler.
