🎯 Changes

deepEqual(a, b, partial?, explicitUndefined?) replaces the options
object. The hot callers (Link option stabilization and active-state checks,
matchRoute) no longer allocate { partial } / { ignoreUndefined: false }
per comparison, and the comparator reads two booleans instead of an options
parameter that saw four object shapes. explicitUndefined (falsy default)
replaces ignoreUndefined: false and reuses the activeOptions vocabulary.

deepEqual is an internal helper; two-argument callers are unaffected.

react-router.minimal shrinks by 48 B gzip (129 raw) on top of the previous
commit; the Link stabilization micro-benchmark improves by ~10% and the
paired Link component runner resolves three cases as faster.

Verification on main

  • router-core test:unit (3264 passed), test:types, test:eslint
  • react-router (1178), solid-router (942 + 51) and vue-router (968) test:unit and test:types: all deepEqual callers in the three link.tsx files are updated here.

Relationship to other PRs

Stacked on #8417 (deepEqual array identity); merge that first and GitHub retargets this one to main.

packages/router-core/tests/replace-equal-deep.bench.ts does not exist on main yet — it arrives with #8411's base branch and still calls deepEqual(search, searchCopy, { partial: true }); once both land, that call needs to become deepEqual(search, searchCopy, true) (the original commit on the #8411 branch already contains that edit).

✅ Checklist

  • I have followed the steps in the Contributing guide.
  • I have tested code changes locally with the relevant test commands, or tests do not apply to this pull request.
  • I fully understand the code in this pull request, including any code generated with AI assistance.

🚀 Release Impact

  • This change affects published code, and I have generated a changeset.
  • This change is docs/CI/dev-only (no release).

Summary by CodeRabbit

  • Bug Fixes

    • Improved route matching consistency for route parameters and search values, including handling of explicitly provided undefined values.
    • Active-link detection now applies search matching rules more reliably across React, Solid, and Vue routers.

  • Improvements

    • Updated deep equality behavior and its public calling convention across router packages.
    • Existing two-argument deep equality usage remains supported for compatibility.

📝 Walkthrough

Walkthrough

The PR changes deepEqual from an options object to positional flags. Router call sites, route matching, tests, benchmarks, and package release metadata now use the updated contract.

Changes

deepEqual flag migration

Layer / File(s) Summary
deepEqual contract and comparison semantics
packages/router-core/src/utils.ts, .changeset/deep-equal-positional-flags.md		 deepEqual now accepts partial and explicitUndefined positional flags. Recursive and object comparisons apply the updated undefined-property behavior.
Router comparison call sites
packages/router-core/src/router.ts, packages/react-router/src/link.tsx, packages/solid-router/src/link.tsx, packages/vue-router/src/link.tsx		 Router matching and link comparisons pass positional flags. matchRoute uses exact equality for route parameters and search values.
Contract tests and benchmarks
packages/router-core/tests/deep-equal-contract.test.ts, packages/router-core/tests/utils.test.ts, packages/router-core/tests/deep-equal.bench.ts		 Tests and benchmarks cover positional flags, undefined-key behavior, partial comparisons, short-circuiting, and updated benchmark cases.

Priority: ⬇️ Low

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

Change: Refactor

Suggested reviewers: sheraff

Merge Risk: ⚪ Minimal · up to b5bc8

No concrete current-head defect remains; the positional-flag migration preserves the established comparison behavior and is ready for normal merge checks.

### 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

### 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`.

[`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.
