@jkrems can you please rebase

Applied on top of latest lkgr.

i'd word this a little bit stronger. using arguments in hashbangs is something that should be avoided in general.

should perhaps (like io.js provided both iojs and node binaries) node provide a node-esm or similar binary, so they can use that in the shebang instead?

Yeah, I assume that'll be where it's heading. The question would be: Would this make a better general command / should it replace node as the "default" binary people would run?

Only if they're invoking node on an extensionless ESM file - if the file has an extension, or if it's CJS, then node would still be preferred.

Since package.json bins can have extensions, this really only affects executable one-off ESM scripts, which won't be the majority (but are still an important use case)

Right, but if node-esm always works (after porting your code to ESM) and node works most of the time - why would you ever tempt fate and use node?

i wouldn't bet on another binary for this --mode option, given opposition to the design of the option, and the weight of an extra binary for very little configuration.

@jkrems it wouldn't work on CJS files, and i'd expect it to throw if you tried to run with --type=esm on a file that had a non-esm file extension - the better question would be why would you tempt fate and use the alternative :-)

How about something like:

Suggested change

Does not work reliably when running via shebang (`#!/usr/bin/env node`)

Note that this flag is not a reliable solution for shebang scripts (`#!/usr/bin/env node -m`) due to multiple arguments not being supported in POSIX environments.

it'd be anything that respects exec(3), so most POSIX platforms

Sure, updated to posix.

Feel free to update the commit directly. This PR is just me suggesting a fix to an earlier PR, I don't have any personal attachment to the exact wording. :)

GeoffreyBooth · 2019-04-18T04:36:02Z

I think this is no longer relevant now that we no longer have a flag that applies to files?

hybrist · 2019-04-18T16:11:43Z

Correct, closing! :)
