Handling Remote Loading Failures
Learn to detect and recover when a federated remote fails to load due to network errors, version mismatches, or deployment issues.
Remotes Can Fail to Load
In federation, a remote is fetched over the network at run time. That fetch can fail: the server is down, the URL is wrong, or a deploy is mid-flight. Your app must handle it.
Failure Modes
Common remote-loading failures include:
- Network timeout fetching
remoteEntry.js - 404 after a remote was redeployed
- Incompatible shared dependency versions
- JavaScript errors during remote bootstrap
