마이크로 프런트엔드란 무엇인가요?

Welcome to Micro Frontends! This style builds big web apps from smaller independent pieces — microservices, applied to your user interface.

Big frontends often start as a monolith: one tightly coupled codebase. That means slow team work, hard-to-scale parts, and changes that break each other.

Micro Frontends fix the monolith by decomposing one giant UI into several small, self-contained apps, each owning a specific part of the experience.

The big payoff is organizational: separate teams own and build their own Micro Frontend independently, cutting coordination and speeding delivery.

Each Micro Frontend is developed, tested, and deployed on its own — so teams pick their own stack, ship smaller safer releases, and iterate faster.

Micro Frontends are feature-centric: each maps to a business domain. An e-commerce site might split into Product Catalog, Shopping Cart, and User Profile.

Picture your app as a Lego city. A monolith has one team build it all at once; Micro Frontends let specialized teams build separate buildings, then combine them.

The main reasons to adopt Micro Frontends: scalability for big apps and teams, agility through faster cycles, and maintainability from small isolated codebases.

At its core, Micro Frontends bring microservice principles to the browser — many frontend apps coexisting in one larger, more modular and flexible app.

Let's check your understanding of what Micro Frontends are about.

Recap: Micro Frontends build large UIs from independent parts, solving monolith pain with independent teams, autonomous tech choices, and better scaling.
