4. @duffleit David Leitner ▪ Technical Consultant for Senacor Technologies ▪ Lecturer for post diploma courses at UAS Technikum Vienna ▪ I do a couple of things around the tech- community I‘m writing code
5. @duffleit A definition of micro frontends The idea of micro frontends is to extend the concepts of micro services to the frontend world.
6. @duffleit Sam Newman: ▪ small and focused on one thing ▪ … to be autonomous ▪ That‘s it WHY we do them? Microservices * UBERHDTV - https://imgur.com/gallery/nup4lfX CVDD HDD/EDD *
7. @duffleit why autonomous? ✅Independent deployments ✅Small interface surface ✅Technology agnostic ✅Based on standards ✅Autonomous operations ✅Parallel Development
8. @duffleit „Microservices are stated as a contrast system to monoliths.“ Where they came from

16. @duffleit But wait, … our microservices have actual human users. - Stefan Tilkov

18. @duffleit the frontend
19. @duffleit The frontend is … not an implementation detail, it is a critical part of a microservice architecture.

48. @duffleit „a consistent UI“ 1) CDN – for static files 2) CMS – for static content 3) A Component Library
49. @duffleit „a component library in code“ SPA-C SPA-B SPA-A component library Time Effort 2019 2020 2021 component library component library a promise that you will save time in the future by reusage. you introduce a dependency between your projects. copy & own
50. @duffleit >> A little copying is better than a little dependency. Rob Pike
51. @duffleit „a component library“ If you really need a component library, then build it framework agnostic. If Angular can be ignored JSX + CSS Modules worked good for us. And, of course web components.
52. @duffleit Web Components in 2019 Think they do What they really do Say they do what people… * If you have real world project experience with a web-component based component library which is running in production, let’s chat afterwards – I pay the beer.

55. @duffleit https://codeburst.io/building-efficient-components-6ee2bdaea542 the metaframework will be the framework
56. @duffleit Hyperlink Integration Build Time Integration Transclusion App Shell Integration Metaframework the agony of choice
57. @duffleit every consultant. always. it depends
58. @duffleit A general decision advice Your application is big?* The need for smooth user interaction Build Time Integration Hyperlink Integration Strongly Independent UI/Domain Parts Complex modularisation needed Transclusion App Shell Integration Meta- Framework * an application is big enough to justify using micro frontends, if slight UI/UX differences between the two most unrelated subpages are acceptable. Yes No

60. @duffleit Key-Takeaways „Think twice if a frontend monolith does not fit your needs and start with a monolith first approach.“
61. @duffleit Key-Takeaways „the 8 facilities of distributed computing are called facilities for a reason“
62. @duffleit Key-Takeaways „Consider the frontend as part of your microservice architecture – and solve UI specific problems with UI specific solutions.“
63. @duffleit Use the right tool for the right job. @duffleit
