10. @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!
11. @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')
12. @ManfredSteyer How to Get the Microfrontend's URL? Shell (Host) Microfrontend (Remote) RemoteEntry.js <script src="…"></script>
13. @ManfredSteyer How to Share Libs? Shell (Host) Microfrontend (Remote) shared: [ "@angular/core", "…" ] shared: [ "@angular/core", "…" ]
14. @ManfredSteyer
15. @ManfredSteyer Default Behavior Selecting the highest compatible version 10.0 10.1
16. @ManfredSteyer Default Behavior Conflict: No highest compatible version 11.0 10.1
17. @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
18. @ManfredSteyer Configuring Singletons shared: { "my-lib": { singleton: true } } 11.0 10.1
19. @ManfredSteyer Configuring Singletons shared: { "my-lib": { singleton: true, strictVersion: true // Error instead of warning! } } 11.0 10.1
20. @ManfredSteyer Relaxing Version Requirements shared: { "my-lib": { requiredVersion: ">=1.0.1 <11.1.1" } }

28. @ManfredSteyer Dynamic Module Federation Shell (Host) Microfrontend (Remote) remotes: { mfe1: "mfe1" } exposes: { Cmp: './my.cmp.ts' } import('mfe1/Cmp')
29. @ManfredSteyer Dynamic Module Federation Shell (Host) Microfrontend (Remote) remotes: { } exposes: { Cmp: './my.cmp.ts' } import('mfe1/Cmp')
30. @ManfredSteyer Dynamic Module Federation Shell (Host) Microfrontend (Remote) remotes: { } exposes: { Cmp: './my.cmp.ts' } loadRemoteModule({ remoteEntry: 'http://…', remoteName: 'mfe1', exposedModule: './Cmp' })
31. @ManfredSteyer Dynamic Module Federation Shell (Host) Microfrontend (Remote) remotes: { } exposes: { Cmp: './my.cmp.ts' } loadRemoteModule({ remoteEntry: 'http://…', remoteName: 'mfe1', exposedModule: './Cmp' }) Helper Function using the Webpack API

34. @ManfredSteyer Well … Webpack 5: final @angular-architects/module-federation: final CLI 11: Experimental webpack 5 support CLI 12: Official webpack 5 support (May 2021)
35. @ManfredSteyer Free eBook ANGULARarchitects.io/book Updated for Module Federation and Alternatives
36. @ManfredSteyer Conclusion Module Federation Loading Separately Deployed Code Version Mismatches Federated Angular Dynamic Federation
