#47 - Micro-Frontends and the Socio-Technical Aspect - Luca Mezzalira

“Micro-frontends are representations of business subdomains. We should differentiate them from components, because components are solving technical problems. Micro-frontends are looking from the product side on how you can create value in isolation for your users."

In this episode, Luca described the concept of micro-frontends in-depth, along with the where and when companies should apply this concept for building the frontends. Luca also shared about the principles behind micro-frontends, why it is important to be technology agnostic, and how to design the CI/CD pipelines. Luca also mentioned some of the common pitfalls and anti-patterns that we should avoid when using micro-frontends, as well as sharing his tips on how organisations can start adopting micro-frontends in their architecture.
