Enterprise Microfrontend Architecture

I have worked with microfrontend applications where multiple independently developed frontend applications are composed into a larger enterprise experience.

This included Angular applications, React applications, shared routing concerns, cross-application communication, and reusable frontend patterns.

Problem

Large enterprise applications often grow beyond the boundaries of a single frontend codebase.

Different teams need to work independently while still delivering a consistent user experience.

Technical approach

Using single-spa, separate frontend applications can be registered and mounted based on route or application state.

This architecture allows teams to own separate areas of the UI while still participating in one larger application shell.

Areas of focus

• Angular microapplications - Independent Angular apps with routing
• React microapplications - Standalone React components and apps
• single-spa orchestration - Application lifecycle management
• Shared application state - Cross-app data sharing
• Route-based loading - Dynamic module loading
• Cross-application communication - Event bus and messaging
• RxJS-based data flow - Reactive state management
• Unit testing and maintainability - Test strategies for microapps
