9. @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!
10. @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')
11. @ManfredSteyer How to Get the Microfrontend's URL? Shell (Host) Microfrontend (Remote) RemoteEntry.js <script src="…"></script>
12. @ManfredSteyer How to Share Libs? Shell (Host) Microfrontend (Remote) shared: [ "@angular/core", "…" ] shared: [ "@angular/core", "…" ]

15. @ManfredSteyer Custom Builder
16. @ManfredSteyer
17. @ManfredSteyer 1) ng add @angular-architects/module-federation 2) Adjust generated configuration 3) ng serve

20. @ManfredSteyer Dynamic Module Federation Shell (Host) Microfrontend (Remote) remotes: { mfe1: "mfe1" } exposes: { Cmp: './my.cmp.ts' } import('mfe1/Cmp')
21. @ManfredSteyer Dynamic Module Federation Shell (Host) Microfrontend (Remote) remotes: { } exposes: { Cmp: './my.cmp.ts' } import('mfe1/Cmp')
22. @ManfredSteyer Dynamic Module Federation Shell (Host) Microfrontend (Remote) remotes: { } exposes: { Cmp: './my.cmp.ts' } loadRemoteModule({ remoteEntry: 'http://…', remoteName: 'mfe1', exposedModule: './Cmp' })
23. @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

26. @ManfredSteyer Dealing with Version Mismatches SemVer by Default: Highest compatiable version Fallback: Use own version Relaxing: Configure a range of accepted versions Singleton: Warning or error
27. @ManfredSteyer Example for SemVer and Fallback • Shell: my-lib: ^10.0.0 • MFE1: my-lib: ^10.1.1 • MFE2: my-lib: ^9.0.0 Result: • Shell and MFE1 share ^10.1.1 • MFE2 falls back to its own version ^9.0.0
28. @ManfredSteyer Configuring Singletons shared: { "my-lib": { singleton: true, strictVersion: true // Error instead of warning! } }
29. @ManfredSteyer Relaxing Version Requirements shared: { "my-lib": { requiredVersion: ">=1.0.1 <11.1.1" } }

31. @ManfredSteyer Well … Webpack 5 is final! CLI 11 (RC) allows to opt into webpack 5 CLI 11 very soon
32. @ManfredSteyer Free eBook ANGULARarchitects.io/book Updated for Module Federation and Alternatives
33. @ManfredSteyer Conclusion Module Federation Loading Separately Deployed Code Micro Frontends Federated Angular Dynamic Federation Version Mismatches
