Summary by CodeRabbit

  • Bug Fixes

    • Improved hydration behavior to prevent unnecessary updates during rerenders of hydration-aware components.
    • Fixed link rendering so native and custom links consistently filter unsupported properties while preserving custom props, disabled accessibility behavior, and forwarded refs.
    • Improved server-to-client hydration consistency, including correct fallback content during initial hydration and reliable transition to client content.

  • Tests

    • Added coverage for link property handling and hydration behavior across server-side rendering and client-side rendering.

📝 Walkthrough

Walkthrough

The PR stabilizes useHydrated snapshot getter references and separates native and custom Link prop filtering. It adds SSR, hydration, prop, accessibility, hook-result, and ref coverage, plus patch changesets for both updates.

Changes

React Router rendering behavior

Layer / File(s) Summary
Hydration snapshot stability
packages/react-router/src/ClientOnly.tsx, packages/react-router/tests/useHydrated.test.tsx, .changeset/deep-chefs-work.md		 useHydrated uses stable module-level snapshot getters. Tests cover getter identity, SSR fallback output, client hydration, recoverable errors, and subsequent renders.
Link prop filtering
packages/react-router/src/link.tsx, packages/react-router/tests/link-state-props.test.tsx, .changeset/rare-chefs-shine.md		 Native and custom Link branches filter props separately. Tests cover SSR and client output, accessibility props, hook results, custom props, and forwarded refs.

Priority: ⬇️ Low

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 regression. The failing test (tanstack-vue-start-e2e-basic — client-side script loading) is completely unrelated to our react-router Link performance changes, and the project was not touched by this PR. With a 0% flakiness rate and no similar failures on other branches, this appears to be a pre-existing infrastructure issue.

No code changes were suggested for this issue.

perf(react-router): filter native Link props once
bc2822e 
Omit type and disabled in one rest copy for native anchors instead of copying the hook result twice. Custom components still receive disabled, and useLinkProps still returns supported type/disabled values. Add client/SSR coverage for those distinctions, refs and render-function children.

Against 6e4584e0d8, four balanced fresh-process pairs with one implementation per process reduced client parameter-updater CPU from 15.61515 to 15.14615 ms per eight-navigation batch (-3.00%, 95% CI -4.19% to -1.80%); wall -3.04% (-4.29% to -1.78%). SSR shared-param CPU fell from 1.45208 to 1.41006 ms per four-request batch (-2.89%, CI -3.80% to -1.98%); wall -2.85% (-3.84% to -1.84%). Earlier co-loaded comparisons were inconclusive.

React Router minimal gzip -5 bytes to 85773; full +1 to 89358. Other React fixtures vary -3 to +4 bytes, raw +14; Solid/Vue remain byte-identical. No public API or prop functionality removed.

perf(react-router): stabilize hydration snapshot getters
d249878 
Reuse the existing true/false snapshot functions instead of allocating them on every useHydrated render. This lets React skip unnecessary store-instance passive bookkeeping without changing hydration values or adding hooks. Cover stable identities and an actual server-render/hydrateRoot transition.

Against b6971a434a, four balanced fresh-process pairs per case (200 warmup and 500 measured eight-navigation batches) reduced parameter-updater CPU from 15.16880 to 14.99436 ms (-1.15%, 95% CI -1.84% to -0.46%); wall -1.05% (-1.62% to -0.47%). Middleware CPU fell from 15.23708 to 14.81729 ms (-2.75%, CI -4.46% to -1.01%); wall -2.79% (-4.53% to -1.01%).

React Router minimal/full gzip increases 14/15 bytes for this isolated fix, remaining below the initial branch baseline. All Solid/Vue bundle output is unchanged. Public APIs, server snapshots and client hydration transitions are preserved.

### Patch Changes

- [#8418](TanStack/router#8418)
[`e561fa1`](TanStack/router@e561fa1)
- `deepEqual` now takes its flags as positional arguments —
`deepEqual(a, b, partial?, explicitUndefined?)` — instead of an options
object. The router's hot callers (Link option stabilization and
active-state checks, `matchRoute`) no longer allocate an options object
per comparison, and the comparator reads two booleans instead of a
polymorphic object. `explicitUndefined` replaces `ignoreUndefined:
false`. `deepEqual` is an internal helper; it stays exported for
compatibility of two-argument calls.

- [#8419](TanStack/router#8419)
[`a1c8d1a`](TanStack/router@a1c8d1a)
- `resolvePath` (internal helper) now takes positional arguments —
`resolvePath(base, to, trailingSlash?, cache?)` — so `buildLocation` and
`matchRoute` no longer allocate an options object per path resolution.

- [#8204](TanStack/router#8204)
[`cbbfbe3`](TanStack/router@cbbfbe3)
- Stream large deferred SSR hydration payloads through a
backpressure-aware router transport, fail known setup errors before
response creation, and close cancelled or expired transforms safely.

Start now cancels discarded middleware and HEAD response bodies,
including plain streams and derived branches.

Server-function raw streams share one ordered response. Arbitrary or
sequential consumption can require potentially unbounded buffering of
unread data on the client. Cancelling one raw stream discards it
locally, while aborting the whole call cancels the response and server
work. Consume streams concurrently, cancel unused streams promptly, or
use separate calls when independent backpressure is required. A raw
stream that exceeds its unread-byte limit now fails alone; sibling
stream

<summary><b>1.170.36</b></summary>

### Patch Changes

- [#8390](TanStack/router#8390)
[`b747fb8`](TanStack/router@b747fb8)
- Keep the Link location cache out of server bundles: `buildLocation`
only creates, reads and writes it when `isServer` is false. Render React
Links on the server without the extra prop copies and the forwarded-ref
hook. Link SSR rendering is 20-40% faster in the Link benchmarks and the
React Start SSR request loop about 7% faster.

React `activeProps` and `inactiveProps` now follow one precedence rule
on every link, including links whose destination is blocked for using a
disallowed scheme: state props override element props, `ref` and event
handlers, while `href`, `disabled` and `target` stay controlled by the
router. Previously a blocked link ignored a `ref` or handler from its
inactive props.

React `Link` and `useLinkProps` split router options from element props
with one key set on the client and the server. Element props pass
through as given: external links forward them verbatim, falsy values
included, and `useLinkProps` now returns `children` for
router-controlled links as it already did for external ones.

- [#8324](TanStack/router#8324)
[`6387d58`](TanStack/router@6387d58)
- Reuse hydration snapshot getters to avoid unnecessary store-instance
effect updates when Links and other hydration-aware components rerender.

- [#8318](TanStack/router#8318)
[`9b2adaf`](TanStack/router@9b2adaf)
- Allow active and inactive Link props to override base element props in
React and Solid while preserving class/style merging. Keep React's
`href`, `target`, and `disabled` values controlled by routing options.
Preserve Vue object and nested-array class bindings, including reactive
updates and server rendering, without mutating cach

### Patch Changes

- [#8204](TanStack/router#8204)
[`cbbfbe3`](TanStack/router@cbbfbe3)
- Stream large deferred SSR hydration payloads through a
backpressure-aware router transport, fail known setup errors before
response creation, and close cancelled or expired transforms safely.

Start now cancels discarded middleware and HEAD response bodies,
including plain streams and derived branches.

Server-function raw streams share one ordered response. Arbitrary or
sequential consumption can require potentially unbounded buffering of
unread data on the client. Cancelling one raw stream discards it
locally, while aborting the whole call cancels the response and server
work. Consume streams concurrently, cancel unused streams promptly, or
use separate calls when independent backpressure is required. A raw
stream that exceeds its unread-byte limit now fails alone; sibling
streams and the JSON result keep flowing.

The JSON wire shape of a `RawStream` server-function argument changed.
Clients and servers must run matching versions for requests that pass a
`RawStream`.

The frame-protocol constants (`FRAME_TYPE_*`, `MAX_FRAME_PAYLOAD_SIZE`,
`MAX_FRAMED_STREAMS`) moved from the `@tanstack/start-client-core` root
to the `@tanstack/start-client-core/client-rpc` subpath.

Router requests whose `Accept` header allows neither `text/html` nor
`*/*` now receive `406 Not Acceptable` instead of `500`.

Framework adapters share the body `<Scripts>` composition
(`getSsrBodyScriptParts`, `composeSsrBodyScripts`) and the eager HTML
response wrapper (`renderSsrHtmlResponse`) from `@tanstack/router-core`.

Solid SSR now emits one document type and renders late lazy errors
through route boundaries. A Solid `<Await>` without a `fallback` no
longer holds the streamed shell; it renders inside the nearest
`<Suspense>` boundary like React and Vue, and now renders falsy resolved
values.

`Option.none()` for those fields.

- [#8162](Effect-TS/effect#8162)
[`716e0c0`](Effect-TS/effect@716e0c0)
Thanks @<!---->tim-smart! - Fix published declarations referencing
symbols stripped as `@internal`, which broke consumers compiling with
`skipLibCheck: false`. `Effectable.d.ts` now uses the public
`Effect.TypeId`, `Match.d.ts` no longer aliases an internal `Contextual`
type, `Schema.d.ts` ships the `AnnotationSchemaConstraint` alias it
references, and the CLI's `toFlagDoc` helper is marked internal so it no
longer leaks `Param.getParamMetadata`.

- [#8160](Effect-TS/effect#8160)
[`d4e4ad5`](Effect-TS/effect@d4e4ad5)
Thanks @<!---->gcanti! - Fix `SchemaRepresentation.toCodeDocument`
generating invalid TypeScript for optional tuple elements containing
unions or nested readonly tuples. Optional element types are now
parenthesized, for example `readonly [(string | number)?]` instead of
`readonly [string | number?]`. Generated runtime schemas are unchanged.

- [#8158](Effect-TS/effect#8158)
[`b1988f4`](Effect-TS/effect@b1988f4)
Thanks @<!---->gcanti! - Fix `SchemaRepresentation.toCodeDocument`
dropping Struct fields named `__proto__`

### Patch Changes

- [#4885](PostHog/posthog-js#4885)
[`39a8980`](PostHog/posthog-js@39a8980)
Thanks [@<!---->decknamec](https://github.com/decknamec)! - Server-side
feature flags now resolve in posthog-node and posthog-edge even when a
proxy rewrites the request's `User-Agent`. Flags restricted to the
`client` runtime now resolve to `undefined` in these SDKs, where a
rewritten `User-Agent` previously let them through.
