How to link to routes from components?

You have a component that renders a list of products. How would you make each product name navigate to its detail page when clicked?

If you use the <Link> component but forget to wrap your app with a router, what error will you see and why?

We need to add a 'Back' button that returns the user to the previous page, but sometimes the user lands directly on the page via an external link. How would you implement this navigation safely?

During a recent release, clicking a navigation link caused the page to reload instead of using client‑side routing. What could cause that and how would you debug it?

Our application has a deep nested route hierarchy and we want to generate links dynamically based on the current location. How would you build a utility that creates correct relative links and avoids broken URLs when the route structure changes?

We are seeing performance regressions because many components render <Link> with heavy inline functions. What strategies would you use to minimize re‑renders while keeping navigation declarative?

We are migrating a legacy monolith to a micro‑frontend architecture, each team owns its own route subtree. How would you design a shared routing layer that allows teams to add links without tightly coupling to each other's code?

Our SEO team wants server‑side rendered routes but also needs client‑side navigation for a seamless SPA experience. What architectural patterns would you adopt to reconcile SSR link generation with client navigation, and what trade‑offs are involved?
