Vue 2 to Vue 3 has been equally painful for atleast one app I know about. Compare that to last three versions of Astro (with web components) and it has been a breeze.
> I migrated from Angular 4 to 18 (including ngrx and material) and didn't find it especially problematic.
The pain varies from project to project. Mine has been touched by a generation of developers of different levels of proficiency. A more disciplined project would’ve been easier to migrate in retrospective.
I think Angular ecosystem really missed the train with schematics (even ngrx!). Schematics could tackle a lot of toil if implemented exhaustively but apart from Angular and Material, nobody else seems to implement them effectively for brownfield projects.
