what is tanstack fr?

This project brings TanStack Router to NativeScript, which means it helps developers handle navigation and screen-to-screen routing in mobile apps. NativeScript lets you build native iOS and Android apps using web technologies like TypeScript, and TanStack Router is a popular tool for managing how users move between different views or pages. Together, they give mobile developers a way to structure app navigation using a tool many already know from web development. The README is quite sparse, so it doesn't go into detail on the specific mechanics. At a high level, the package provides an integration layer: you install it into a NativeScript project, and it wires up TanStack's routing system so it works with mobile app navigation patterns instead of browser URLs. The repo includes a demo app you can run to see it in action, and setup is a single command followed by a start script that gives you build and demo options. The target audience is developers building mobile apps with NativeScript who want a modern, type-safe routing solution. A concrete use case would be a startup building a cross-platform app with multiple screens, say, a login flow, a main dashboard, and a settings page, where they want clean, predictable navigation without writing custom routing logic from scratch. Teams already using TanStack Router on the web would find this appealing because they can reuse their routing knowledge on mobile. The project requires Node 22 or higher, which is worth noting since that's a relatively recent version and may not be installed by default. Beyond that, the README doesn't cover tradeoffs, limitations, or how the integration handles mobile-specific navigation patterns like back buttons or deep linking. It's a young project with minimal documentation, so anyone considering it should expect to explore the demo app and source code to understand the full picture.
