Repro steps

1. run ng update @angular/something
2. Git diff of package.json:

-}
+}
\ No newline at end of file

Desired functionality

Not a big deal but ng update should add a newline at te end of package.json so that git doesn't complain anymore.

This issue also seems to occur in angular.json after ng add.

[wojteko22]

This is very annoying, especially if you use sth like Prettier on CI, which requires newlines – to have consistent code formatting and green build you must add this newline after each update command. And to avoid diff cluttering
