From a monolithic frontend to a modular architecture
Many e-commerce platforms have grown organically over the years. This often results in a tight coupling between system components. The consequence: even minor changes can have unexpected side effects and further development becomes cumbersome and slow.
The larger a development team is, the more complex communication, coordination and release processes become.
Micro Frontends solve exactly this problem: they decompose the entire application, including the frontend, into independent systems. This allows teams to develop, test and deploy in parallel.
What is Micro Frontends?
Micro Frontends is an architectural approach that extends the principle of microservices to the frontend: division by business domain, independent development and deployment, and clear interfaces between systems.
The goal is to enable multiple teams to work in parallel without unnecessary coordination. Each team is responsible for its own system and takes “ownership.” This leads to intrinsic motivation and self-optimization.
To ensure a consistent look and feel of the platform for users, certain common standards and integration patterns are essential.
What is changing:
Faster releases
Independent Micro Frontends enable parallel development. New features go live in a matter of days.
Fewer dependencies
Changes affect only single modules, not the entire system. Teams operate with minimal alignment. Barriers are eliminated, complexity is reduced.
Modernizing monoliths step-by-step
Existing frontends are being decoupled one by one. No complete rewrite, no big bang.
Open to new technology
Each team continues to develop its own part independently. Framework changes or updates can be implemented without project-wide coordination. New technologies can be rolled out more quickly.
What I see time and time again: As soon as a team takes real ownership of its part of the platform, the coordination meetings disappear on their own. No more waiting for next week’s deployment. No more feature freezes because someone else isn’t finished yet. Those who are given real responsibility, deliver results and learn from direct feedback. It is exactly this speed of iteration that is becoming so much more important with AI coding tools right now.

Everything you need to know about Micro Frontends
Who is the Micro Frontends approach best suited for?
This architecture shows its advantages in large development organizations. If a single team is capable of developing the entire software application, a well-structured monolith is a good choice. As soon as you start thinking about splitting teams, the Micro Frontend approach should be considered. Instead of dividing work along technical aspects such as frontend and backend – which requires a lot of coordination – you should consider a functional separation by domain. Two interdisciplinary teams are generally much faster than two technically specialized teams that have to coordinate on every feature.
Why not just rebuild everything from scratch?
If your current system is basically working, that’s not necessary. A complete rebuild is often expensive, risky and time-consuming. Micro Frontends allow you to modernize specific parts of your system without disrupting day-to-day operations.
Does the use of Micro Frontends involving multiple teams not actually increase complexity?
Micro Frontends reduce complexity where it is truly expensive: in coordination between teams, in release processes and in dependencies. In client projects, we have found that work can be done more efficiently when teams are as small as possible. If a team of 20 people is split into four smaller teams, they can accomplish more because decoupling frees up resources.
How can I envision the implementation of Micro Frontends in my system?
We don’t replace a functioning frontend with a new one. Instead of building everything from scratch, we modernize step by step – together with you. We build the first Micro Frontends exactly where they can deliver value quickly.
Everything starts with your current situation and the identification of existing pain points (e.g. time-to-market, costs, redundancy, quality etc.). We check sensible integration patterns, validate the solution technically and start with an initial use case that is easily to isolate, but already represents a first real step toward migrating to the new architecture. After that, the architecture is expanded step by step: integration with the existing system, additional teams, additional systems, shared standards. This creates a frontend architecture out of your existing system that is faster, more modular and easier to manage.
