11. @ManfredSteyer Idea const Component = await import('http://other-app/xyz') Does not work

    with webpack/ Angular CLI Even lazy parts must be known at compile time!

12. @ManfredSteyer Webpack 5 Module Federation Shell (Host) Microfrontend (Remote) //

    Maps Urls in // webpack config remotes: { mfe1: "mfe1" } // Expose files in // webpack config exposes: { './Cmp': './my.cmp.ts' } import('mfe1/Cmp')

13. @ManfredSteyer How to Get the Microfrontend's URL? Shell (Host) Microfrontend

    (Remote) RemoteEntry.js <script src="…"></script>

14. @ManfredSteyer How to Share Libs? Shell (Host) Microfrontend (Remote) shared:

    [ "@angular/core", "…" ] shared: [ "@angular/core", "…" ]

16. @ManfredSteyer Default Behavior Selecting the highest compatible version 10.0 10.1

17. @ManfredSteyer Default Behavior Conflict: No highest compatible version 11.0 10.1

18. @ManfredSteyer Example • Shell: my-lib: ^10.0 • MFE1: my-lib: ^10.1

    • MFE2: my-lib: ^9.0 • MFE3: my-lib: ^9.1 Result: • Shell and MFE1 share ^10.1 • MFE2 and MFE3 share ^9.1

19. @ManfredSteyer Configuring Singletons shared: { "my-lib": { singleton: true }

    } 11.0 10.1

20. @ManfredSteyer Configuring Singletons shared: { "my-lib": { singleton: true, strictVersion:

    true // Error instead of warning! } } 11.0 10.1

21. @ManfredSteyer Relaxing Version Requirements shared: { "my-lib": { requiredVersion: ">=1.0.1

    <11.1.1" } }
