How to globally hide fsevents warning?

Question

Many questions such as this one talk about this very annoying behavior on non-mac OS.

When I run npm install I want to remain aware of any warnings, but in Windows or Linux I would get this:

$ ./npm install
npm WARN deprecated chokidar@2.1.8: Chokidar 2 will break on node v14+. Upgrade to chokidar 3 with 15x less dependencies.
npm WARN deprecated fsevents@1.2.13: fsevents 1 will break on node v14+ and could be using insecure binaries. Upgrade to fsevents 2.
npm notice created a lockfile as package-lock.json. You should commit this file.

npm WARN bootstrap@4.5.0 requires a peer of jquery@1.9.1 - 3 but none is installed. You must install peer dependencies yourself.

Notice that most WARN are caused by fsevents which is not available outside of macOS.

Some suggest to hide every warnings with:

npm --logevel=error install

Others advise to use:

npm install --no-optional --no-shrinkwrap --no-package-lock

But all these methods does not seem right to me. I only want to execute npm install and have a configuration file that would hide all optional dependencies that are not available on my operating system.

How can I do that?

npm install --no-optional prevents this warning.
