6. @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!
7. @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')
8. @ManfredSteyer How to Get the Microfrontend's URL? Shell (Host) Microfrontend (Remote) RemoteEntry.js <script src="…"></script>
9. @ManfredSteyer How to Share Libs? Shell (Host) Microfrontend (Remote) shared: [ "@angular/core", "…" ] shared: [ "@angular/core", "…" ]

17. @ManfredSteyer Dealing with Version Mismatch SemVer by Default: Highest compatiable version Fallback: Use own version Relaxing: Configure a range of accepted versions Singleton: Warning or error
18. @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
19. @ManfredSteyer Configuring Singletons shared: { "my-lib": { singleton: true, strictVersion: true // Error instead of warning! } }
20. @ManfredSteyer Relaxing Version Requirements shared: { "my-lib": { requiredVersion: ">=1.0.1 <11.1.1" } }
21. @ManfredSteyer Free eBook ANGULARarchitects.io/book Updated for Module Federation and Alternatives
22. @ManfredSteyer When can we have it? Webpack 5 and Module Federation: final Angular CLI must support webpack 5 too Angular CLI 11 (Beta) allows to opt into webpack 5 Angular CLI 11 ? (fall 2020)
23. @ManfredSteyer Conclusion Module Federation Loading Separately Deployed Code Federated Angular Version Mismatch
