Hi all,  
I would like to display a message in the log after installation using the `postinstall` script but it seems that this is not natively possible (see [[BUG] npm install does not run postinstall nor does it show name & version of installed pkg · Issue #3647 · npm/cli · GitHub](https://github.com/npm/cli/issues/3647)).

@knolleary would it be possible to add the following flags to the installer (registry)?

- `--foreground-scripts`
- `--loglevel=warn`: to avoid spamming the log (or maybe info level)

Thanks

Lately I was digging intensively in the details of installer.  
May I ask what kind of "spamming the log" you experienced? I'm not aware of any (generated by npm)...

You're right, after several tests the `loglevel` is not necessary. I don't really have any spam except for audits. (because I forgot to put the flag 🤦‍♂️ ).  
I hadn't checked but by default it's on `notice` which is higher than `info`.  
I had defined the `loglevel` to avoid logs like debug but it will not be useful 😅

What do you think @knolleary about enabling logs during pre/post install scripts?

I don't know if it will be useful to many but I would like to use it to notify the user that they have an action to do. (Knowing very well that not everyone looks at the logs...)
