Robust Error Boundaries
Implement React Error Boundaries or similar mechanisms to isolate errors within individual Micro Frontends.
Errors in Federated Apps
In Micro Frontend architectures, multiple independent applications work together. This distributed nature makes robust error handling incredibly important.
An error in one part of your system shouldn't bring down the entire user experience. We need ways to contain and manage these issues.
Preventing Cascading Errors
Imagine your main application (the host) loads a remote Micro Frontend. If that remote MFE crashes due to an unhandled error, what happens?
Without proper isolation, the error could "bubble up" and crash the host application, leading to a blank screen or broken experience for the user. This is a cascading failure.
