setComponentStalenessCheck

Summary

Installs the process-wide component compatibility check used during development refreshes.

When the check returns true, reconciliation replaces existing instances of that component instead of preserving their state. This is a low-level integration point for HMR runtimes.

Signature

function setComponentStalenessCheck(check: ComponentStalenessCheck): void

Parameters

check

Callback that returns true when instances of a component must be remounted.
