01 — Scope
“Design a micro-frontend architecture where multiple teams independently develop, deploy, and run their own frontend modules within a single application shell.”
02 — Federation API
Define the manifest, bundle delivery, event bus, and shared dependency endpoints.
03 — Architecture
Map the MFE architecture: app shell, team containers, shared runtime, CDN pipeline, and event bus.
04 — App Shell
Build the application shell that orchestrates MFE layout slots and team assignments.
05 — Remote Containers
Load remote MFE containers with independent latency and bundle sizes.
06 — Shared Dependencies
Deduplicate React, ReactDOM, and design tokens across independently-built MFEs.
07 — Event Bus
Build pub/sub communication between MFEs using a typed event bus.
08 — Isolation Strategy
Choose between iframe, Web Component, and Module Federation isolation boundaries.
09 — Cross-MFE Routing
Handle URL ownership and navigation handoffs between independently-deployed MFEs.
10 — CSS Scoping
Prevent style collisions when multiple teams define the same class names.
11 — Error Isolation
Contain MFE failures with error boundaries so one team's crash doesn't take down the whole app.
12 — Version Management
Resolve dependency version conflicts when teams upgrade at different paces.
13 — Bundle Performance
Optimize bundle loading with prefetching, code splitting, and network-aware waterfall visualization.
14 — Contract Testing
Define and verify event contracts between MFEs to catch breaking changes before deployment.
15 — Full System
Run the complete micro-frontend system: independent deployment, cross-MFE events, and error isolation.
