// React currently throws a warning when using useLayoutEffect on the server.
|
|
// To get around it, we can conditionally useEffect on the server (no-op) and
|
|
// useLayoutEffect in the browser. We need useLayoutEffect to ensure the store
|
|
// subscription callback always has the selector from the latest render commit
|
|
// available, otherwise a store update may happen between render and the effect,
|
|
// which may cause missed updates; we also must ensure the store subscription
|
|
// is created synchronously, otherwise a store update may occur before the
|
|
// subscription is created and an inconsistent state may be observed
|
|
// Matches logic in React's `shared/ExecutionEnvironment` file
