Next-Router-State-Tree explorer

Soft-navigate between the routes below. The panel on the right intercepts every RSC fetch and decodes the Next-Router-State-Tree the browser attaches. Hard-load any URL — no fetch happens, so nothing is captured.

Dynamic route — segment [slug] = kanaka

Kanaka Pigeon

Caloenas canacorum

IUCN status
Extinct (prehistoric)
Mass
~900 g

Subfossil bones from New Caledonia and Tonga. Larger than the living Nicobar, exterminated by early human colonization.

The next outbound RSC fetch will encode [slug] as ["slug", "kanaka", "d"] in the state tree the browser sends. Click a different species and watch the right-hand panel: only that array's middle element changes between captures; the static parents stay put.
