perf(router-core): optimize route tree processing

[Sheraff]

Summary

• fuse static and dynamic route-node construction while preserving case sensitivity, parser reuse, wildcard aliases, parent links, and trie depth
• record dynamic sibling arrays only when they first need sorting, then sort them once after construction instead of walking the full trie
• derive matcher frame depth from trie nodes instead of carrying duplicate depth state
• consolidate and expand regression coverage for sibling ordering, parser priorities and fallback, static-node reuse, route masks, case sensitivity, and pathless/optional depth
• add a patch changeset for @tanstack/router-core

Consolidates

This replaces the overlapping work in:

• perf(router-core): fuse static route node construction #7981
• perf(router-core): fuse dynamic route node construction #7974
• perf(router-core): derive match frame depth #7973
• Optimize route tree sibling sorting #7969

#7974's fused dynamic-node implementation subsumes #7969's production sorting change; #7969's unique ordering tests are retained.

Runtime performance

Compared with origin/main at 697ebb6d using the same focused Vitest benchmark files in separate worktrees:

• general route-tree construction: 7.6% to 10.7% faster across mostly-static, dense-dynamic, reused-shape, and route-mask cases
• static construction: 3.5% to 14.1% faster across sensitive/insensitive and shared/unique-prefix cases
• route matching: 5.4% to 8.4% faster across deep-static and optional-segment distributions

No focused runtime case regressed.

Validation

• router-core unit: 105 files passed; 1,536 tests passed; 3 expected failures
• router-core types: TypeScript 5.6 through 7.0 passed
• router-core ESLint: 0 errors (26 existing warnings outside this diff)
• focused construction/static/matching benchmarks compared against origin/main
• Prettier, git diff --check, and changeset status passed
• five independent reviews found no correctness or runtime-performance blocker

Summary by CodeRabbit

• Performance

  • Improved route-tree construction and route matching performance.
  • Enhanced prioritization of dynamic, optional, and wildcard routes for more accurate matching.

• Bug Fixes

  • Improved handling of case-insensitive paths, pathless routes, route masks, and fallback matching.
  • Prevented route ordering issues when multiple routes have similar patterns.

• Tests

  • Expanded coverage for route specificity, node reuse, wildcard handling, and route-mask behavior.

📝 Walkthrough

Walkthrough

Route-tree construction now resolves route-local options, reuses trie nodes, and sorts only newly populated dynamic sibling lists. Matching derives depth from trie nodes. Tests cover route and route-mask specificity, fallback, reuse, case handling, and pathless routes.

Changes

Route tree optimization

Layer / File(s)	Summary
Route parsing and selective sibling sorting packages/router-core/src/new-process-route-tree.ts, .changeset/faster-route-trees.md	Route parsing groups dynamic, optional, and wildcard nodes into recorded sibling lists. Construction sorts only those lists instead of recursively sorting the full tree.
Trie-derived matcher specificity packages/router-core/src/new-process-route-tree.ts	Match frames no longer store depth. Optional skip masks and specificity comparisons derive depth from trie nodes.
Route and mask matching coverage packages/router-core/tests/new-process-route-tree.test.ts	Tests cover specificity ordering, parser fallback, node reuse, case handling, pathless tie-breaking, and route-mask matching.

Estimated code review effort: 4 (Complex) | ~45 minutes

Pass dynamicListsToSort through findSingleMatch.

parseSegments is not exported, but findSingleMatch calls it without dynamicListsToSort. A single top-level flat route containing two or more sibling dynamic segments can remain unsorted, so matches may pick lower-priority siblings before declaration order is restored.

producer and consumer by using one consistent key: preferably record skipped
optional nodes in buildBranch order and update nodeIndex accordingly, or change
both sides to depth-based indexing; ensure skipping behavior remains correct

_{Comparing codex/consolidate-route-tree-optimizations (fb90b1e) with main (697ebb6)}

[Sheraff]

Summary

• fuse static and dynamic route-node construction while preserving case sensitivity, parser reuse, wildcard aliases, parent links, and trie depth
• record dynamic sibling arrays only when they first need sorting, then sort them once after construction instead of walking the full trie
• derive matcher frame depth from trie nodes instead of carrying duplicate depth state
• consolidate and expand regression coverage for sibling ordering, parser priorities and fallback, static-node reuse, route masks, case sensitivity, and pathless/optional depth
• add a patch changeset for @tanstack/router-core

Consolidates

This replaces the overlapping work in:

• perf(router-core): fuse static route node construction #7981
• perf(router-core): fuse dynamic route node construction #7974
• perf(router-core): derive match frame depth #7973
• Optimize route tree sibling sorting #7969

#7974's fused dynamic-node implementation subsumes #7969's production sorting change; #7969's unique ordering tests are retained.

Runtime performance

Compared with origin/main at 697ebb6d using the same focused Vitest benchmark files in separate worktrees:

• general route-tree construction: 7.6% to 10.7% faster across mostly-static, dense-dynamic, reused-shape, and route-mask cases
• static construction: 3.5% to 14.1% faster across sensitive/insensitive and shared/unique-prefix cases
• route matching: 5.4% to 8.4% faster across deep-static and optional-segment distributions

No focused runtime case regressed.

Validation

• router-core unit: 105 files passed; 1,536 tests passed; 3 expected failures
• router-core types: TypeScript 5.6 through 7.0 passed
• router-core ESLint: 0 errors (26 existing warnings outside this diff)
• focused construction/static/matching benchmarks compared against origin/main
• Prettier, git diff --check, and changeset status passed
• five independent reviews found no correctness or runtime-performance blocker

Summary by CodeRabbit

• Performance

  • Improved route-tree construction and route matching performance.
  • Enhanced prioritization of dynamic, optional, and wildcard routes for more accurate matching.

• Bug Fixes

  • Improved handling of case-insensitive paths, pathless routes, route masks, and fallback matching.
  • Prevented route ordering issues when multiple routes have similar patterns.

• Tests

  • Expanded coverage for route specificity, node reuse, wildcard handling, and route-mask behavior.

📝 Walkthrough

Walkthrough

Route-tree construction now resolves route-local options, reuses trie nodes, and sorts only newly populated dynamic sibling lists. Matching derives depth from trie nodes. Tests cover route and route-mask specificity, fallback, reuse, case handling, and pathless routes.

Changes

Route tree optimization

Layer / File(s)	Summary
Route parsing and selective sibling sorting packages/router-core/src/new-process-route-tree.ts, .changeset/faster-route-trees.md	Route parsing groups dynamic, optional, and wildcard nodes into recorded sibling lists. Construction sorts only those lists instead of recursively sorting the full tree.
Trie-derived matcher specificity packages/router-core/src/new-process-route-tree.ts	Match frames no longer store depth. Optional skip masks and specificity comparisons derive depth from trie nodes.
Route and mask matching coverage packages/router-core/tests/new-process-route-tree.test.ts	Tests cover specificity ordering, parser fallback, node reuse, case handling, pathless tie-breaking, and route-mask matching.

Estimated code review effort: 4 (Complex) | ~45 minutes

Pass dynamicListsToSort through findSingleMatch.

parseSegments is not exported, but findSingleMatch calls it without dynamicListsToSort. A single top-level flat route containing two or more sibling dynamic segments can remain unsorted, so matches may pick lower-priority siblings before declaration order is restored.

producer and consumer by using one consistent key: preferably record skipped
optional nodes in buildBranch order and update nodeIndex accordingly, or change
both sides to depth-based indexing; ensure skipping behavior remains correct

_{Comparing codex/consolidate-route-tree-optimizations (fb90b1e) with main (697ebb6)}

[Sheraff]

Summary

• fuse static and dynamic route-node construction while preserving case sensitivity, parser reuse, wildcard aliases, parent links, and trie depth
• record dynamic sibling arrays only when they first need sorting, then sort them once after construction instead of walking the full trie
• derive matcher frame depth from trie nodes instead of carrying duplicate depth state
• consolidate and expand regression coverage for sibling ordering, parser priorities and fallback, static-node reuse, route masks, case sensitivity, and pathless/optional depth
• add a patch changeset for @tanstack/router-core

Consolidates

This replaces the overlapping work in:

• perf(router-core): fuse static route node construction #7981
• perf(router-core): fuse dynamic route node construction #7974
• perf(router-core): derive match frame depth #7973
• Optimize route tree sibling sorting #7969

#7974's fused dynamic-node implementation subsumes #7969's production sorting change; #7969's unique ordering tests are retained.

Runtime performance

Compared with origin/main at 697ebb6d using the same focused Vitest benchmark files in separate worktrees:

• general route-tree construction: 7.6% to 10.7% faster across mostly-static, dense-dynamic, reused-shape, and route-mask cases
• static construction: 3.5% to 14.1% faster across sensitive/insensitive and shared/unique-prefix cases
• route matching: 5.4% to 8.4% faster across deep-static and optional-segment distributions

No focused runtime case regressed.

Validation

• router-core unit: 105 files passed; 1,536 tests passed; 3 expected failures
• router-core types: TypeScript 5.6 through 7.0 passed
• router-core ESLint: 0 errors (26 existing warnings outside this diff)
• focused construction/static/matching benchmarks compared against origin/main
• Prettier, git diff --check, and changeset status passed
• five independent reviews found no correctness or runtime-performance blocker

Summary by CodeRabbit

• Performance

  • Improved route-tree construction and route matching performance.
  • Enhanced prioritization of dynamic, optional, and wildcard routes for more accurate matching.

• Bug Fixes

  • Improved handling of case-insensitive paths, pathless routes, route masks, and fallback matching.
  • Prevented route ordering issues when multiple routes have similar patterns.

• Tests

  • Expanded coverage for route specificity, node reuse, wildcard handling, and route-mask behavior.

📝 Walkthrough

Walkthrough

Route-tree construction now resolves route-local options, reuses trie nodes, and sorts only newly populated dynamic sibling lists. Matching derives depth from trie nodes. Tests cover route and route-mask specificity, fallback, reuse, case handling, and pathless routes.

Changes

Route tree optimization

Layer / File(s)	Summary
Route parsing and selective sibling sorting packages/router-core/src/new-process-route-tree.ts, .changeset/faster-route-trees.md	Route parsing groups dynamic, optional, and wildcard nodes into recorded sibling lists. Construction sorts only those lists instead of recursively sorting the full tree.
Trie-derived matcher specificity packages/router-core/src/new-process-route-tree.ts	Match frames no longer store depth. Optional skip masks and specificity comparisons derive depth from trie nodes.
Route and mask matching coverage packages/router-core/tests/new-process-route-tree.test.ts	Tests cover specificity ordering, parser fallback, node reuse, case handling, pathless tie-breaking, and route-mask matching.

Estimated code review effort: 4 (Complex) | ~45 minutes

Pass dynamicListsToSort through findSingleMatch.

parseSegments is not exported, but findSingleMatch calls it without dynamicListsToSort. A single top-level flat route containing two or more sibling dynamic segments can remain unsorted, so matches may pick lower-priority siblings before declaration order is restored.

producer and consumer by using one consistent key: preferably record skipped
optional nodes in buildBranch order and update nodeIndex accordingly, or change
both sides to depth-based indexing; ensure skipping behavior remains correct

_{Comparing codex/consolidate-route-tree-optimizations (fb90b1e) with main (697ebb6)}

[Sheraff]

Summary

• fuse static and dynamic route-node construction while preserving case sensitivity, parser reuse, wildcard aliases, parent links, and trie depth
• record dynamic sibling arrays only when they first need sorting, then sort them once after construction instead of walking the full trie
• derive matcher frame depth from trie nodes instead of carrying duplicate depth state
• consolidate and expand regression coverage for sibling ordering, parser priorities and fallback, static-node reuse, route masks, case sensitivity, and pathless/optional depth
• add a patch changeset for @tanstack/router-core

Consolidates

This replaces the overlapping work in:

• perf(router-core): fuse static route node construction #7981
• perf(router-core): fuse dynamic route node construction #7974
• perf(router-core): derive match frame depth #7973
• Optimize route tree sibling sorting #7969

#7974's fused dynamic-node implementation subsumes #7969's production sorting change; #7969's unique ordering tests are retained.

Runtime performance

Compared with origin/main at 697ebb6d using the same focused Vitest benchmark files in separate worktrees:

• general route-tree construction: 7.6% to 10.7% faster across mostly-static, dense-dynamic, reused-shape, and route-mask cases
• static construction: 3.5% to 14.1% faster across sensitive/insensitive and shared/unique-prefix cases
• route matching: 5.4% to 8.4% faster across deep-static and optional-segment distributions

No focused runtime case regressed.

Validation

• router-core unit: 105 files passed; 1,536 tests passed; 3 expected failures
• router-core types: TypeScript 5.6 through 7.0 passed
• router-core ESLint: 0 errors (26 existing warnings outside this diff)
• focused construction/static/matching benchmarks compared against origin/main
• Prettier, git diff --check, and changeset status passed
• five independent reviews found no correctness or runtime-performance blocker

Summary by CodeRabbit

• Performance

  • Improved route-tree construction and route matching performance.
  • Enhanced prioritization of dynamic, optional, and wildcard routes for more accurate matching.

• Bug Fixes

  • Improved handling of case-insensitive paths, pathless routes, route masks, and fallback matching.
  • Prevented route ordering issues when multiple routes have similar patterns.

• Tests

  • Expanded coverage for route specificity, node reuse, wildcard handling, and route-mask behavior.

📝 Walkthrough

Walkthrough

Route-tree construction now resolves route-local options, reuses trie nodes, and sorts only newly populated dynamic sibling lists. Matching derives depth from trie nodes. Tests cover route and route-mask specificity, fallback, reuse, case handling, and pathless routes.

Changes

Route tree optimization

Layer / File(s)	Summary
Route parsing and selective sibling sorting packages/router-core/src/new-process-route-tree.ts, .changeset/faster-route-trees.md	Route parsing groups dynamic, optional, and wildcard nodes into recorded sibling lists. Construction sorts only those lists instead of recursively sorting the full tree.
Trie-derived matcher specificity packages/router-core/src/new-process-route-tree.ts	Match frames no longer store depth. Optional skip masks and specificity comparisons derive depth from trie nodes.
Route and mask matching coverage packages/router-core/tests/new-process-route-tree.test.ts	Tests cover specificity ordering, parser fallback, node reuse, case handling, pathless tie-breaking, and route-mask matching.

Estimated code review effort: 4 (Complex) | ~45 minutes

Pass dynamicListsToSort through findSingleMatch.

parseSegments is not exported, but findSingleMatch calls it without dynamicListsToSort. A single top-level flat route containing two or more sibling dynamic segments can remain unsorted, so matches may pick lower-priority siblings before declaration order is restored.

optional nodes in buildBranch order and update nodeIndex accordingly, or change
both sides to depth-based indexing; ensure skipping behavior remains correct

_{Comparing codex/consolidate-route-tree-optimizations (fb90b1e) with main (697ebb6)}

[Sheraff]

Summary

• fuse static and dynamic route-node construction while preserving case sensitivity, parser reuse, wildcard aliases, parent links, and trie depth
• record dynamic sibling arrays only when they first need sorting, then sort them once after construction instead of walking the full trie
• derive matcher frame depth from trie nodes instead of carrying duplicate depth state
• consolidate and expand regression coverage for sibling ordering, parser priorities and fallback, static-node reuse, route masks, case sensitivity, and pathless/optional depth
• add a patch changeset for @tanstack/router-core

Consolidates

This replaces the overlapping work in:

• perf(router-core): fuse static route node construction #7981
• perf(router-core): fuse dynamic route node construction #7974
• perf(router-core): derive match frame depth #7973
• Optimize route tree sibling sorting #7969

#7974's fused dynamic-node implementation subsumes #7969's production sorting change; #7969's unique ordering tests are retained.

Runtime performance

Compared with origin/main at 697ebb6d using the same focused Vitest benchmark files in separate worktrees:

• general route-tree construction: 7.6% to 10.7% faster across mostly-static, dense-dynamic, reused-shape, and route-mask cases
• static construction: 3.5% to 14.1% faster across sensitive/insensitive and shared/unique-prefix cases
• route matching: 5.4% to 8.4% faster across deep-static and optional-segment distributions

No focused runtime case regressed.

Validation

• router-core unit: 105 files passed; 1,536 tests passed; 3 expected failures
• router-core types: TypeScript 5.6 through 7.0 passed
• router-core ESLint: 0 errors (26 existing warnings outside this diff)
• focused construction/static/matching benchmarks compared against origin/main
• Prettier, git diff --check, and changeset status passed
• five independent reviews found no correctness or runtime-performance blocker

Summary by CodeRabbit

• Performance

  • Improved route-tree construction and route matching performance.
  • Enhanced prioritization of dynamic, optional, and wildcard routes for more accurate matching.

• Bug Fixes

  • Improved handling of case-insensitive paths, pathless routes, route masks, and fallback matching.
  • Prevented route ordering issues when multiple routes have similar patterns.

• Tests

  • Expanded coverage for route specificity, node reuse, wildcard handling, and route-mask behavior.

📝 Walkthrough

Walkthrough

Route-tree construction now resolves route-local options, reuses trie nodes, and sorts only newly populated dynamic sibling lists. Matching derives depth from trie nodes. Tests cover route and route-mask specificity, fallback, reuse, case handling, and pathless routes.

Changes

Route tree optimization

Layer / File(s)	Summary
Route parsing and selective sibling sorting packages/router-core/src/new-process-route-tree.ts, .changeset/faster-route-trees.md	Route parsing groups dynamic, optional, and wildcard nodes into recorded sibling lists. Construction sorts only those lists instead of recursively sorting the full tree.
Trie-derived matcher specificity packages/router-core/src/new-process-route-tree.ts	Match frames no longer store depth. Optional skip masks and specificity comparisons derive depth from trie nodes.
Route and mask matching coverage packages/router-core/tests/new-process-route-tree.test.ts	Tests cover specificity ordering, parser fallback, node reuse, case handling, pathless tie-breaking, and route-mask matching.

Estimated code review effort: 4 (Complex) | ~45 minutes

Pass dynamicListsToSort through findSingleMatch.

parseSegments is not exported, but findSingleMatch calls it without dynamicListsToSort. A single top-level flat route containing two or more sibling dynamic segments can remain unsorted, so matches may pick lower-priority siblings before declaration order is restored.

optional nodes in buildBranch order and update nodeIndex accordingly, or change
both sides to depth-based indexing; ensure skipping behavior remains correct

_{Comparing codex/consolidate-route-tree-optimizations (fb90b1e) with main (697ebb6)}

[Sheraff]

Summary

• fuse static and dynamic route-node construction while preserving case sensitivity, parser reuse, wildcard aliases, parent links, and trie depth
• record dynamic sibling arrays only when they first need sorting, then sort them once after construction instead of walking the full trie
• derive matcher frame depth from trie nodes instead of carrying duplicate depth state
• consolidate and expand regression coverage for sibling ordering, parser priorities and fallback, static-node reuse, route masks, case sensitivity, and pathless/optional depth
• add a patch changeset for @tanstack/router-core

Consolidates

This replaces the overlapping work in:

• perf(router-core): fuse static route node construction #7981
• perf(router-core): fuse dynamic route node construction #7974
• perf(router-core): derive match frame depth #7973
• Optimize route tree sibling sorting #7969

#7974's fused dynamic-node implementation subsumes #7969's production sorting change; #7969's unique ordering tests are retained.

Runtime performance

Compared with origin/main at 697ebb6d using the same focused Vitest benchmark files in separate worktrees:

• general route-tree construction: 7.6% to 10.7% faster across mostly-static, dense-dynamic, reused-shape, and route-mask cases
• static construction: 3.5% to 14.1% faster across sensitive/insensitive and shared/unique-prefix cases
• route matching: 5.4% to 8.4% faster across deep-static and optional-segment distributions

No focused runtime case regressed.

Validation

• router-core unit: 105 files passed; 1,536 tests passed; 3 expected failures
• router-core types: TypeScript 5.6 through 7.0 passed
• router-core ESLint: 0 errors (26 existing warnings outside this diff)
• focused construction/static/matching benchmarks compared against origin/main
• Prettier, git diff --check, and changeset status passed
• five independent reviews found no correctness or runtime-performance blocker

Summary by CodeRabbit

• Performance

  • Improved route-tree construction and route matching performance.
  • Enhanced prioritization of dynamic, optional, and wildcard routes for more accurate matching.

• Bug Fixes

  • Improved handling of case-insensitive paths, pathless routes, route masks, and fallback matching.
  • Prevented route ordering issues when multiple routes have similar patterns.

• Tests

  • Expanded coverage for route specificity, node reuse, wildcard handling, and route-mask behavior.

📝 Walkthrough

Walkthrough

Route-tree construction now resolves route-local options, reuses trie nodes, and sorts only newly populated dynamic sibling lists. Matching derives depth from trie nodes. Tests cover route and route-mask specificity, fallback, reuse, case handling, and pathless routes.

Changes

Route tree optimization

Layer / File(s)	Summary
Route parsing and selective sibling sorting packages/router-core/src/new-process-route-tree.ts, .changeset/faster-route-trees.md	Route parsing groups dynamic, optional, and wildcard nodes into recorded sibling lists. Construction sorts only those lists instead of recursively sorting the full tree.
Trie-derived matcher specificity packages/router-core/src/new-process-route-tree.ts	Match frames no longer store depth. Optional skip masks and specificity comparisons derive depth from trie nodes.
Route and mask matching coverage packages/router-core/tests/new-process-route-tree.test.ts	Tests cover specificity ordering, parser fallback, node reuse, case handling, pathless tie-breaking, and route-mask matching.

Estimated code review effort: 4 (Complex) | ~45 minutes

Pass dynamicListsToSort through findSingleMatch.

parseSegments is not exported, but findSingleMatch calls it without dynamicListsToSort. A single top-level flat route containing two or more sibling dynamic segments can remain unsorted, so matches may pick lower-priority siblings before declaration order is restored.

optional nodes in buildBranch order and update nodeIndex accordingly, or change
both sides to depth-based indexing; ensure skipping behavior remains correct

_{Comparing codex/consolidate-route-tree-optimizations (fb90b1e) with main (697ebb6)}

[Sheraff]

Summary

• fuse static and dynamic route-node construction while preserving case sensitivity, parser reuse, wildcard aliases, parent links, and trie depth
• record dynamic sibling arrays only when they first need sorting, then sort them once after construction instead of walking the full trie
• derive matcher frame depth from trie nodes instead of carrying duplicate depth state
• consolidate and expand regression coverage for sibling ordering, parser priorities and fallback, static-node reuse, route masks, case sensitivity, and pathless/optional depth
• add a patch changeset for @tanstack/router-core

Consolidates

This replaces the overlapping work in:

• perf(router-core): fuse static route node construction #7981
• perf(router-core): fuse dynamic route node construction #7974
• perf(router-core): derive match frame depth #7973
• Optimize route tree sibling sorting #7969

#7974's fused dynamic-node implementation subsumes #7969's production sorting change; #7969's unique ordering tests are retained.

Runtime performance

Compared with origin/main at 697ebb6d using the same focused Vitest benchmark files in separate worktrees:

• general route-tree construction: 7.6% to 10.7% faster across mostly-static, dense-dynamic, reused-shape, and route-mask cases
• static construction: 3.5% to 14.1% faster across sensitive/insensitive and shared/unique-prefix cases
• route matching: 5.4% to 8.4% faster across deep-static and optional-segment distributions

No focused runtime case regressed.

Validation

• router-core unit: 105 files passed; 1,536 tests passed; 3 expected failures
• router-core types: TypeScript 5.6 through 7.0 passed
• router-core ESLint: 0 errors (26 existing warnings outside this diff)
• focused construction/static/matching benchmarks compared against origin/main
• Prettier, git diff --check, and changeset status passed
• five independent reviews found no correctness or runtime-performance blocker

Summary by CodeRabbit

• Performance

  • Improved route-tree construction and route matching performance.
  • Enhanced prioritization of dynamic, optional, and wildcard routes for more accurate matching.

• Bug Fixes

  • Improved handling of case-insensitive paths, pathless routes, route masks, and fallback matching.
  • Prevented route ordering issues when multiple routes have similar patterns.

• Tests

  • Expanded coverage for route specificity, node reuse, wildcard handling, and route-mask behavior.

📝 Walkthrough

Walkthrough

Route-tree construction now resolves route-local options, reuses trie nodes, and sorts only newly populated dynamic sibling lists. Matching derives depth from trie nodes. Tests cover route and route-mask specificity, fallback, reuse, case handling, and pathless routes.

Changes

Route tree optimization

Layer / File(s)	Summary
Route parsing and selective sibling sorting packages/router-core/src/new-process-route-tree.ts, .changeset/faster-route-trees.md	Route parsing groups dynamic, optional, and wildcard nodes into recorded sibling lists. Construction sorts only those lists instead of recursively sorting the full tree.
Trie-derived matcher specificity packages/router-core/src/new-process-route-tree.ts	Match frames no longer store depth. Optional skip masks and specificity comparisons derive depth from trie nodes.
Route and mask matching coverage packages/router-core/tests/new-process-route-tree.test.ts	Tests cover specificity ordering, parser fallback, node reuse, case handling, pathless tie-breaking, and route-mask matching.

Estimated code review effort: 4 (Complex) | ~45 minutes

Pass dynamicListsToSort through findSingleMatch.

parseSegments is not exported, but findSingleMatch calls it without dynamicListsToSort. A single top-level flat route containing two or more sibling dynamic segments can remain unsorted, so matches may pick lower-priority siblings before declaration order is restored.

optional nodes in buildBranch order and update nodeIndex accordingly, or change
both sides to depth-based indexing; ensure skipping behavior remains correct

_{Comparing codex/consolidate-route-tree-optimizations (fb90b1e) with main (697ebb6)}

[Sheraff]

Summary

• fuse static and dynamic route-node construction while preserving case sensitivity, parser reuse, wildcard aliases, parent links, and trie depth
• record dynamic sibling arrays only when they first need sorting, then sort them once after construction instead of walking the full trie
• derive matcher frame depth from trie nodes instead of carrying duplicate depth state
• consolidate and expand regression coverage for sibling ordering, parser priorities and fallback, static-node reuse, route masks, case sensitivity, and pathless/optional depth
• add a patch changeset for @tanstack/router-core

Consolidates

This replaces the overlapping work in:

• perf(router-core): fuse static route node construction #7981
• perf(router-core): fuse dynamic route node construction #7974
• perf(router-core): derive match frame depth #7973
• Optimize route tree sibling sorting #7969

#7974's fused dynamic-node implementation subsumes #7969's production sorting change; #7969's unique ordering tests are retained.

Runtime performance

Compared with origin/main at 697ebb6d using the same focused Vitest benchmark files in separate worktrees:

• general route-tree construction: 7.6% to 10.7% faster across mostly-static, dense-dynamic, reused-shape, and route-mask cases
• static construction: 3.5% to 14.1% faster across sensitive/insensitive and shared/unique-prefix cases
• route matching: 5.4% to 8.4% faster across deep-static and optional-segment distributions

No focused runtime case regressed.

Validation

• router-core unit: 105 files passed; 1,536 tests passed; 3 expected failures
• router-core types: TypeScript 5.6 through 7.0 passed
• router-core ESLint: 0 errors (26 existing warnings outside this diff)
• focused construction/static/matching benchmarks compared against origin/main
• Prettier, git diff --check, and changeset status passed
• five independent reviews found no correctness or runtime-performance blocker

Summary by CodeRabbit

• Performance

  • Improved route-tree construction and route matching performance.
  • Enhanced prioritization of dynamic, optional, and wildcard routes for more accurate matching.

• Bug Fixes

  • Improved handling of case-insensitive paths, pathless routes, route masks, and fallback matching.
  • Prevented route ordering issues when multiple routes have similar patterns.

• Tests

  • Expanded coverage for route specificity, node reuse, wildcard handling, and route-mask behavior.

📝 Walkthrough

Walkthrough

Route-tree construction now resolves route-local options, reuses trie nodes, and sorts only newly populated dynamic sibling lists. Matching derives depth from trie nodes. Tests cover route and route-mask specificity, fallback, reuse, case handling, and pathless routes.

Changes

Route tree optimization

Layer / File(s)	Summary
Route parsing and selective sibling sorting packages/router-core/src/new-process-route-tree.ts, .changeset/faster-route-trees.md	Route parsing groups dynamic, optional, and wildcard nodes into recorded sibling lists. Construction sorts only those lists instead of recursively sorting the full tree.
Trie-derived matcher specificity packages/router-core/src/new-process-route-tree.ts	Match frames no longer store depth. Optional skip masks and specificity comparisons derive depth from trie nodes.
Route and mask matching coverage packages/router-core/tests/new-process-route-tree.test.ts	Tests cover specificity ordering, parser fallback, node reuse, case handling, pathless tie-breaking, and route-mask matching.

Estimated code review effort: 4 (Complex) | ~45 minutes

Pass dynamicListsToSort through findSingleMatch.

parseSegments is not exported, but findSingleMatch calls it without dynamicListsToSort. A single top-level flat route containing two or more sibling dynamic segments can remain unsorted, so matches may pick lower-priority siblings before declaration order is restored.

optional nodes in buildBranch order and update nodeIndex accordingly, or change
both sides to depth-based indexing; ensure skipping behavior remains correct
