perf: unify route bindings in constructors

[Sheraff]

Summary by CodeRabbit

• Improvements

  • Reduced router bundle size across React, Solid, and Vue integrations through unified route API bindings.
  • Preserved route-specific hooks, navigation, matching, data access, and Link behavior.

• Bug Fixes

  • Ensured regular and root routes consistently expose all expected framework APIs and link functionality.

• Tests

  • Added coverage verifying route and root route API availability across all supported frameworks.

📝 Walkthrough

Walkthrough

The React, Solid, and Vue routers now install route APIs through shared initializers. Route-specific IDs and paths remain bound. Tests verify that route and root route instances own every API member. A patch changeset covers all three packages.

Changes

Unified route API bindings

Layer / File(s)	Summary
React route API initialization packages/react-router/src/route.tsx, packages/react-router/tests/route.test.tsx, .changeset/easy-streets-stare.md	Route and RootRoute use initReactRouteApi. Tests verify ownership of hooks and Link. The changeset declares patch releases for the three router packages.
Solid route API initialization packages/solid-router/src/route.tsx, packages/solid-router/tests/route.test.tsx	Route and RootRoute use initSolidRouteApi. The initializer assigns route-scoped hooks, navigation, and Link. Tests verify own-property exposure.
Vue route API initialization packages/vue-router/src/route.ts, packages/vue-router/tests/route.test.tsx	Route and RootRoute use initVueRouteApi. The initializer preserves route IDs, full paths, selector forwarding, and non-strict loader calls. Tests verify hook and Link ownership.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 258ce

The constructor-based route-binding refactor is localized across the three adapters, but the initializer target typing may reject adapter-specific members under strict TypeScript, potentially causing build or type-check failures. This is currently unverified and is not a merge blocker, but it should receive explicit owner follow-up.

508-549: 📐 Maintainability & Code Quality

⚠️ Unverified finding
Sandbox verification was unavailable.

Verify the initializer target type.

Each initializer accepts AnyRoute but writes adapter-specific use*, useNavigate, and Link members. If AnyRoute resolves to the core route type, strict TypeScript rejects these property assignments. Use an adapter-specific target interface or intersection type that declares the assigned members.

• packages/react-router/src/route.tsx#L508-L549: type the initializer target with the React route API members.
• packages/solid-router/src/route.tsx#L466-L499: type the initializer target with the Solid route API members.
• packages/vue-router/src/route.ts#L472-L509: type the initializer target with the Vue route API members.

As per coding guidelines, **/*.{ts,tsx} must use TypeScript strict mode with extensive type safety.

Important

At least one additional CI pipeline execution has run since the conclusion below was written and it may no longer be applicable.

Nx Cloud has identified a possible root cause for your failed CI:

We classified this failure as an environment issue rather than a code change because the error — a version mismatch between @rspack/core@2.0.8 and @rspack/binding@2.0.0 — is unrelated to the route-binding refactor in this PR. The failing project (tanstack-start-example-basic-rsbuild) was not touched by our changes, and no lockfile or package configuration was modified. Reinstalling dependencies to align the rspack package versions should resolve the build failure.

No code changes were suggested for this issue.
