Integration Patterns
| Approach | When to use |
|---|---|
Module Federation
|
Share bundles between hosts |
iframes
|
Isolate legacy apps safely |
Web Components
|
Surface component APIs to multiple hosts |
Communication Channels
window.postMessage
Send events between iframes
shared service contracts
Expose emit/listen functions over global APIs
custom events
Dispatch structured events via DOM
Team Autonomy
Define API contracts, test suites, and deployment ownership for each micro-team before shipping.
💡 Pro Tip:
Document shared contracts and version them independently of host deployments.
