1. AngularArchitects.io | @ManfredSteyer Micro Frontends Unmasked Opportunities, Challenges, Alternatives
2. Good Fences Make Good Neighbors!
3. Verticals: Basis for Autonomous Teams Minimal Dependencies Vertical 1 Vertical 2 Vertical 3 Feature Feature Feature Feature Feature Feature Feature Feature Feature
4. Verticals Verticals represent a business domain (ideally!) Verticals as Micro Frontends: Maximizes Independence
5. Opportunities Team Autonomy Adding new Teams & Members Shorter Release Cycles Testability Fault Isolation Runtime Performance Different Technology Stacks
6. Challanges UI/UX Initial Loading Times Coupling Technical Conflicts Complexity Diverging Micro Frontends
7. @ManfredSteyer How to deal with these challenges?
8. @ManfredSteyer Agenda 1. Strategies for Dealing with Challenges 2. Costs of Strategies 3. Alternatives
9. @ManfredSteyer About me… Manfred Steyer, ANGULARarchitects.io (Remote) Angular Workshops and Consulting Google Developer Expert for Angular Blog, Books, Articles, and Talks about Angular Manfred Steyer
10. @ManfredSteyer Strategies for Dealing With Challanges
11. @ManfredSteyer Design Systems Sharing Styles Sharing Libs Shadow DOM UI/UX
12. @ManfredSteyer SSR Automated Performance Checks Sharing Code Initial Loading Times
13. @ManfredSteyer Module Federation Shell (Host) Microfrontend (Remote) // Maps Urls in // webpack config remotes: { mfe1: "http://..." } // Expose files in // webpack config exposes: { Cmp: './my.cmp.ts' } import('mfe1/Cmp')
14. @ManfredSteyer Dynamic Module Federation Shell (Host) Microfrontend (Remote) remotes: { } exposes: { Cmp: './my.cmp.ts' } loadRemoteModule({ type: 'module', remoteEntry: 'http://…', exposedModule: './Cmp' })
15. @ManfredSteyer How to Get the Microfrontend's URL? Shell (Host) Microfrontend (Remote) RemoteEntrypoint.js import('…'); <script src="…"></script>
16. @ManfredSteyer How to Share Libs? Shell (Host) Microfrontend (Remote) shared: [ "@angular/core", "…" ] shared: [ "@angular/core", "…" ]
