How to exit in Node.js

Question

What is the command that is used to exit? (i.e terminate the Node.js process)

Answer 1

Call the global process object's exit method:

process.exit()

From the docs:

process.exit([exitcode])

Ends the process with the specified code. If omitted, exit uses the 'success' code 0.

To exit with a 'failure' code:

process.exit(1);

The shell that executed node should see the exit code as 1.
