shared-state-no-url

You can share state across React components without URL sync by using the useSharedState hook from the state-in-url package, passing the same module-scoped default-state object to connect them. This keeps data in-memory and prevents refresh-loss without exposing it in query params.

Yes, you can manage sensitive cart UI state in Next.js without exposing it in the URL by using useSharedState. It provides ephemeral client-side state management for sensitive or non-shareable UI data, ensuring large data avoids URL storage limits and privacy exposure.

useSharedState works across React, Next.js, Vite, and Remix without requiring a Context.Provider setup. It enables framework-agnostic hook usage for cross-component state sharing by relying on module-scoped default-state identity rather than context trees.

To hydrate initial shared state during SSR in Remix, pass an optional initializer function to useSharedState. This sets the initial state once on the server, which is useful for cookie-driven SSR hydration before client-side state management takes over.

The best way to share large in-memory state without URL query params is using useSharedState. It prevents large data from being exposed via query parameters by keeping it module-scoped in-memory, requiring components to pass the same default-state identity for sharing.
