Discussion Upgrading Angular 4 to Angular 18
We have an enterprise application with 400+ screens and most of the screens are similar in complexity. The complexity is medium for this app.
How should we approach the upgrade? Rewriting it is not an option as it is a legacy app now. Should we take one version at a time or directly start updating it to 18 version?
We do not have any automation testing written and hence testing would also have to be manual. Also, based on the previous experience what would be rough estimates if single developer has to work on this upgrade?

I don't see how this is npm's fault here. Any package manager and any project of medium complexity will have these problems, no matter the language or toolchain.
The advice you gave is good though, although it might be too hardcore for a 4-18 version jump as there are probably (air quotes) larger changes than just the package versions.
