When a Promise is rejected and has no catch handler, the following warning is displayed on stderr:
$ node -p "Promise.reject()"
Promise { <rejected> undefined }
(node:15518) UnhandledPromiseRejectionWarning: undefined
(node:15518) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)
(node:15518) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
$ echo $?
0
This behavior is in place for quite some time now I believe, and maybe it would be time to actually make node exit on a non-zero code.
