11. @ManfredSteyer About me… Manfred Steyer, ANGULARarchitects.io (Remote) Angular Workshops and Consulting Google Developer Expert for Angular Trusted Collaborator in the Angular Team Manfred Steyer
12. @ManfredSteyer 1: Consequences of Microfrontends
13. @ManfredSteyer Booking App Check-in App Boarding App Luggage App Autonomous Teams
14. @ManfredSteyer Autonomous Teams Separate Development Separate Deployment Own architecture decisions Own technology descisions
15. @ManfredSteyer Microfrontends are first and foremost about scaling teams!
16. @ManfredSteyer Challenges
17. @ManfredSteyer Challenges UI Composition UI Consistency Bundle Size/ Sharing Dependencies Version Conflicts between Microfrontends …
18. @ManfredSteyer Module Federation Solves Some of Them! UI Composition UI Consistency Bundle Size/ Sharing Dependencies Version Conflicts between Microfrontends …
19. @ManfredSteyer 2: Webpack 5 Module Federation
20. @ManfredSteyer DEMO
21. @ManfredSteyer How to load separately compiled code?
22. @ManfredSteyer Idea const Component = import('http://other-app/xyz') Does not work with webpack/ Angular CLI Even lazy parts must be known at compile time!
23. @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')
24. @ManfredSteyer How to Get the Microfrontend's URL? Shell (Host) Microfrontend (Remote) RemoteEntrypoint.js <script src="…"></script>
25. @ManfredSteyer How to Share Libs? Shell (Host) Microfrontend (Remote) shared: [ "@angular/core", "…" ] shared: [ "@angular/core", "…" ]
26. @ManfredSteyer Conflicting Shared Libs Option A: Reuse it anyway Option B: Load own Both might be bad Prevent organizationally (e. g. conventions, contracts, monorepos) Integration-Testing
27. @ManfredSteyer DEMO
28. @ManfredSteyer 3: When can we have it?
29. @ManfredSteyer Well … Webpack 5 is currently beta Shown examples: PoC w/ custom webpack conf + patched CLI lib CLI: Not before version 11 (fall 2020) Squeeze federation config into CLI's webpack config Custom Builder (e. g. ngx-build-plus)
30. @ManfredSteyer Free eBook ANGULARarchitects.io/book Updated for Module Federation and Alternatives
31. @ManfredSteyer Conclusion Main Purpose of µFrontends: Scaling Teams Federation: Import From Other App Sharing Libs Take Care of Conflicts
32. @ManfredSteyer Be like Bonnie and think first! Evaluate whether you need µFrontends No: Majestic Monolith Yes: Consider Module Federation
