RFC: Notification system for cli updates

[ruyadorno]

See RFC

this needs to take into account the node version; there's very complex logic (https://github.com/nvm-sh/nvm/blob/master/nvm.sh#L150-L269) for figuring out which npm version works on which node version, and it would be pretty bad if npm suggesting updating on a node version where the act of updating completely hosed the entire node install by breaking npm.

I am not sure this makes sense. It is just one request per week. During an installation there are hundreds of requests.

my guess is that when this was brought up it was with regards to commands that should not necessarily hit the registry, such as npm ls but i do agree with your point, it might be silly and not worth having this listed in the RFC after all

I think it's worth it to keep it if reducing HTTP calls where they may not be necessary is a goal of the project (I think that's a fair and valid goal).

Feedback from OpenRFC meeting:

• state of the registry engineering resources makes it difficult to commit to adding new features to the registry right now
• let's follow up with how the situation will evolve there and reiterate back on this when appropriate

[ruyadorno]

Action Item:

• Update the RFC to reflect recent updates in npm7 beta so that the RFC should be mostly about registry-side changes and the requests the cli is going to perform
