The new approach uses a postMessage-style API with origin-based access control via an allowedOrigins prop, allowing sandboxes to send messages directly to each other. Communication is not automatically bidirectional — both sender and receiver must explicitly declare each other in their allowedOrigins. Permissions can also be updated dynamically at runtime. This enables micro-frontend dashboards and plugin systems with less boilerplate and tighter security. ## Full article daily.dev links to this article rather than hosting it.
