Function: withLifecycleRoot()

withLifecycleRoot<T>(root, fn): T

Defined in: ../domwise/dist/index.d.ts:2910

Runs fn with the lifecycle root temporarily set to root, restoring the previous root afterwards even if fn throws.

Use this instead of calling currentLifecycleRoot directly so that a thrown error cannot leave a stale root in the global state.

Type Parameters

T

T

Return type of fn.

Parameters

root

Element

Root to install for the duration of fn (null/undefined clears it).

fn

() => T

Callback executed while the root is installed.

Returns

T

The value returned by fn.
