Micro Frontends: Architecture and Implementation


Micro frontends enable teams to work independently on different parts of an application. Here's how to implement this architecture.


What are Micro Frontends?


Micro frontends extend the microservices concept to the frontend. Each micro frontend is independently developed, tested, and deployed.


Implementation Strategies


Module Federation

Webpack 5's Module Federation allows sharing code between applications at runtime. This is one of the most popular approaches.


Build-time Integration

Combine micro frontends at build time. Simpler but less flexible than runtime integration.


Runtime Integration

Load micro frontends at runtime using JavaScript. More flexible but requires careful orchestration.


Benefits


  • Team autonomy
  • Independent deployments
  • Technology diversity
  • Scalability

  • Challenges


  • Shared state management
  • Styling conflicts
  • Performance overhead
  • Testing complexity

  • Conclusion


    Micro frontends are powerful but require careful planning. Start simple and evolve your architecture as needed.
