My bad. If React Loadable does, this does:
If you read the article there’s a component called “React Universal Component” which is the spiritual successor to React Loadable, doing what its creator hinted was its future (SSR).
It also can work in async-only scenarios, such as Meteor. I can’t quite tell if Meteor has SSR with its “exact code splitting” technique??? If so, than like React Loadable, it uniquely automatically renders synchronously when it can.
