You don't need post-install scripts for this. Use optionalDependencies instead https://github.com/nrwl/nx/blob/master/packages/nx/package.j...

Each of those deps contains a constraint installing only for the relevant platform.

As far as I can understand from the documentation, that doesn't actually specify in that config that one of them is required, does it? That is, if they _all_ fail to install as far as the system is concerned there's nothing wrong? There will be runtime errors of course, but that's sort of disappointing…

That’s cool, now I wish all libraries that need binaries would opt to use that instead of post script

Do keep in mind that the binaries are still binaries. Even if your installation process doesn't run any untrusted code from the package, you can't audit the binaries like you might the .js files prior to first run.

As stated, you manually approve them.
