    @duffleit David Leitner § Technical Expert at Senacor Technologies §

    Lecturer for post diploma courses at UAS Technikum Wien § I do a couple of things around the tech- community § I‘m writing code

    @duffleit A definition of micro frontends The idea of micro

    frontends is to extend the concepts of micro services to the frontend world.
  3. 4.

    @duffleit Sam Newman: § small and focused on one thing

    § … to be autonomous § That‘s it WHY do we need this? Independent deployments Autonomous operations Technology agnostic Based on standards Parallel Development Small interface surface Microservices

    @duffleit The frontend is … not an implementation detail, it

    is a critical part of a microservice architecture.

    @duffleit Flavour #3: Server Side Includes or Edge Side Includes

    @duffleit „a consistent UI“ ! CDN – for static files

    " CMS – for static content # A Component Library $ for one framework $ technology agnostic
  24. 46.

    @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

    @duffleit Key-Takeaways KISS: „think twice if a frontend monolith does

    not fit your needs and start with a monolith first approach.“
  27. 49.

    @duffleit Key-Takeaways „Consider the frontend as part of your microservice

    architecture – and solve UI specific problems with UI specific solutions.“
  28. 50.

    @duffleit Key-Takeaways „micro frontends are not a stack or technology

    – everyone who tells you this, wants to sell you something.“
