[RRFC] An option to stop after the first fail when running a script in workspaces

[rpominov]

Motivation ("The Why")

I use npm run build-and-test --workspaces in a CI. If the script fails in one of the workspaces, it can be difficult to find the error in the CI log as it's followed by the output of the successful runs in the other workspaces.

How

Current Behaviour

There's no way that I know of to tell the cli to stop execution after the first fail.

Desired Behaviour

There's an option like --fail-fast.

[Twipped]

I literally JUST ran afoul of this exact problem. Test failures at package levels aren't halting CI workflows because --workspaces doesn't relay the error code.

[rpominov]

In my experience, it does relay the error code, just doesn't exit immediately. I believe the relevant code is here:

https://github.com/npm/cli/blob/f2340f816f5a137038945229bf8a0d30160e76e8/lib/commands/run-script.js#L205-L227

If it exits with 0 code for you, updating npm may help.

I think this may be related to #575 , which has has some good conversations around this kind of behavior during the weekly meetings and so I think there is good traction on that issue. (I noticed it has been tagged for release 8.x 👀 )

Ah, great. I couldn't find an existing issue. This is a duplicate then.
