How to exit in Node.js?

on

 

In Node.js, you can exit a Node.js process by using the process.exit() method. This method allows you to explicitly terminate the Node.js application. Here's an example:

javascript
console.log("This is a message before exiting.");

// Exit the Node.js process with a status code (optional)
process.exit(0);

console.log("This message will not be displayed.");

In the example above:

  1. We use console.log to display a message before exiting.

  2. We call process.exit(0) to exit the Node.js process. You can provide an optional exit status code as an argument. By convention, a status code of 0 indicates a successful exit, while non-zero values are often used to indicate errors or abnormal terminations.

  3. Any code after process.exit() will not be executed because the process has already terminated.

Keep in mind that using process.exit() should be done with caution, especially in production code, as it forcefully terminates the Node.js process without giving it a chance to clean up resources or complete asynchronous operations. It's typically used for simple script-like applications or in cases where you need to exit the process explicitly.
