Building a Meetup Tracker with TanStack Router

I walk through the core concepts of TanStack Router by building a meetup-tracking application, from route setup to data-driven pages. The examples show how routing can manage navigation, loading, search filters, and protected pages in a TypeScript React app.

■ Foundations and navigation
- Route trees, root layouts, file-based routes, links, programmatic navigation, and lazy routes
■ Data and application behavior
- Loaders, loading and error states, dynamic meetup details, and URL search filters validated with Zod
- Router context, authentication checks, form mutations, cache invalidation, and route debugging
■ Comparisons and scope
- A closing comparison with React Router and Next.js; TanStack DevTools and deeper Zod instruction are not covered in depth

This walkthrough is aimed at React developers who want to build or evaluate a type-safe routing setup. Follow along by creating the starter project, then adapt the meetup routes, filters, and authentication flow to a small application of your own.
