@ManfredSteyer Selecting the highest compatible version ^10.0 ^10.1
@ManfredSteyer Make sure, your Angular-based libs see exactly the same
Angular version at runtime it was built with! (Don't use ^ or ~ in your package.json)
@ManfredSteyer Conflict: No highest compatible version 11.0 10.1
@ManfredSteyer shared: { "my-lib": { singleton: true } } 11.0
10.1
@ManfredSteyer shared: { "my-lib": { singleton: true, strictVersion: true //
Error instead of warning! } } 11.0 10.1

@ManfredSteyer If you use webpack: No need to hurry. Stick
with webpack Module Federation
@ManfredSteyer If you use esbuild or vite: Give Native Federation
a try and provide feedback
@ManfredSteyer Once, Angular CLI supports esbuild: Give Native Federation a
try and provide feedback
@ManfredSteyer In general: Native Federation is your insurance for the
mid- and long-term
@ManfredSteyer Free eBook (5th Edition) ANGULARarchitects.io/book Module Federation & Nx
@ManfredSteyer Module Federation: Mental Model rocks! Import Maps: Provide low
level building blocks Native Federation: Insurance Try out with esbuild, vite, etc.
