Node.js has a CLI option called
promise runs into an error.
I wanted this option turned on because I wanted my Netlify build script to completely fail if a promise rejected, so that the deployment wouldn’t finish successfully (despite the error) and publish a broken site.
At first, I tried doing it like this:
node build.js --unhandled-rejections=strict
but that didn’t work.
To get it to work, I had to put the
--unhandled-rejections=strict before the name of the Node.js script:
node --unhandled-rejections=strict build.js
Putting it in this order, the CLI argument works and a rejected promise now causes the script to stop running.
