Function useSignal

useSignal<T>(signal: SSignal<T>): T
Subscribes a React component to an SSignal value.

This hook uses React's useSyncExternalStore, making it suitable for concurrent rendering while keeping React components in sync with monitor signals.

Pass a selector to subscribe to part of the value: the component re-renders only when the selected value changes, compared with Object.is or the given isEqual. Use shallowEqual when the selector builds a new object or array.
Type Parameters
- T
Parameters
- signal: SSignal<T>
Returns T
Example
```
const errorRate = useSignal(monitor.network.snapshot, (snap) => snap.window5s.errorRate)
```
