11. @ManfredSteyer Shell (Host) Microfrontend (Remote) // Maps Urls in // webpack config remotes: { mfe1: "http://..." } // Expose files in // webpack config exposes: { './Cmp': './my.cmp.ts' } import('mfe1/Cmp')
12. @ManfredSteyer Shell (Host) Microfrontend (Remote) shared: [ "@angular/core", "…" ] shared: [ "@angular/core", "…" ]
13. @ManfredSteyer 1) ng add @angular-architects/module-federation 2) Adjust generated configuration 3) ng serve

16. @ManfredSteyer Selecting the highest compatible version 10.0 10.1
17. @ManfredSteyer Conflict: No highest compatible version 11.0 10.1
18. @ManfredSteyer shared: { "my-lib": { singleton: true } } 11.0 10.1
19. @ManfredSteyer shared: { "my-lib": { singleton: true, strictVersion: true // Error instead of warning! } } 11.0 10.1
20. @ManfredSteyer shared: { "my-lib": { requiredVersion: ">=1.0.1 <11.1.1" } }
21. @ManfredSteyer •Several options baked-in •However, best option: avoid conflicts upfront
