Micro-frontends anti-patterns

Luca Mezzalira

Luca Mezzalira warns that micro-frontends aren't a silver bullet. Discover the crippling architectural anti-patterns destroying your independent deployments, from global state coupling to broken domain boundaries.

#1 about 5 min

Understanding the engineering benefits of micro-frontend architectures

How incremental upgrades, decentralization, and reduced cognitive load empower scalable engineering teams.

#2 about 5 min

Differentiating domain-aware micro-frontends from UI components

Why micro-frontends must own their business domain rather than exposing large APIs like traditional reusable components.

#3 about 2 min

The architectural risk of a multi-framework integration approach

Why employing multiple user interface libraries should be reserved for legacy migrations rather than treated as a default architectural goal.

#4 about 5 min

Shielding legacy code with anti-corruption integration layers

Wrapping legacy interface inputs into an isolated layer protects the broader application shell from complex technical debt and tight integration coupling.

#5 about 5 min

Managing external dependency versioning and breaking code changes

Choosing composition over inheritance bypasses the operational risks and breaking API changes created by broadly sharing single core libraries.

#6 about 4 min

Avoiding tight coupling through strict unidirectional data flows

Implementing strictly unidirectional flows prevents the brittle testing conditions and unexpected regressions caused by bidirectional information sharing between host and remote.

#7 about 3 min

Preventing design-time coupling with decentralized global state execution

Replacing centralized global state execution with asynchronous publisher-subscriber patterns maintains the independent deployment stability of neighboring remotes.

#8 about 4 min

Mitigating redundant backend API calls across overlapping micro-frontends

Resolving redundant scaling bottlenecks when overlapping micro-frontend domains accidentally bombard backend microservices with identical data requests.

#9 about 4 min

Balancing architectural tradeoffs and long-term decision tracking documentation

Why logging engineering considerations into architectural decision records aligns long-term strategy while acknowledging immediate systemic tradeoffs.

#10 about 8 min

Evaluating inter-app communication mechanisms and monorepo structural limits

Providing structured approaches for routing ephemeral user session tokens, debating monorepo boundaries, and identifying when generic modularity solves architectural problems instead of micro-frontends.
