📝 Walkthrough

Walkthrough

The React, Solid, and Vue router implementations inline isServer ?? router.isServer in SSR conditions. Existing server state handling and client subscriptions remain unchanged. React Link includes comments for bundler dead-code elimination.

Changes

SSR detection

Layer / File(s)Summary
Inline server checks
packages/react-router/src/link.tsx, packages/react-router/src/useRouterState.tsx, packages/solid-router/src/useRouterState.tsx, packages/vue-router/src/useRouterState.tsx
SSR conditions now evaluate isServer ?? router.isServer inline. React Link documents the inline form required for bundler constant folding.
