The case for typed routes in Next.js 14

One of the most underrated features in Next.js 14 is the typedRoutes experimental flag. Enable it with one line in next.config.ts:

experimental: { typedRoutes: true }

Once enabled, every <Link href="...">, useRouter().push(...), and redirect(...) call becomes type-checked against your actual file system routes.

The Problem It Solves

Without typed routes, you can ship broken links silently:

// This compiles fine but 404s at runtime
<Link href="/experiance">Experience</Link>
//             ↑ typo

With typed routes enabled, that line becomes a compile error. The DX is similar to tRPC for API calls — your editor tells you immediately when a route doesn't exist.

The Tradeoff

The only cost is a slightly slower initial build as Next.js generates the route type manifest. On a project with ~30 routes, this adds roughly 2 seconds to next build. Worth it.
