AI BriefingA New Paradigm for Large-Scale Frontend Architecture - Part 1. What is Micro Frontend?
Key point
This article examines the concept of micro frontends, the background behind their emergence, and the integration strategies needed for a true implementation.
Details
Micro Frontend (MFE) is an architectural pattern that splits a web application into small units that can be independently developed, deployed, and operated. This applies the backend concept of Microservices Architecture (MSA) to the frontend, and emerged to overcome the limitations of massive Single Page Applications (SPA).
As application scale grows, the existing Monolithic structure causes the following problems.
- Deployment dependency: Even a small change requires rebuilding and redeploying the entire app
- Tech stack constraints: All teams are forced to use the same framework and version
- Code conflicts and slow builds: Conflicts between teams' work occur frequently, and build/test times increase
Simply separating code alone cannot achieve a true MFE. To become a true MFE, a clear integration strategy is needed regarding when (integration timing) and where (integration location) the separated code pieces will be assembled.
