From 188f3a11a16c20126daa1806da5becc608f04a92 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 29 May 2025 15:33:15 +0000 Subject: [PATCH 1/4] feat(core): Implement various performance optimizations in core libraries This commit introduces several optimizations across the core libraries (`events.ts`, `instance.ts`, `loader.ts`) based on a detailed analysis of potential performance improvements. The following changes have been made: 1. **`libs/core/src/lib/events.ts` (`intersect` function):** * Optimized the `raycastResults.sort()` method by pre-calculating sort keys (priority, distance, state existence) before sorting. This reduces redundant calls to `getInstanceState` within the sort comparator, improving performance when many raycast results are present. 2. **`libs/core/src/lib/instance.ts`:** * **`notifyAncestors` function:** * Refactored `notificationCache` from `Map` to `WeakMap`, using the instance object itself as the key. * Removed the `queueMicrotask`-based global cache clearing. * This change improves memory safety by preventing potential leaks associated with string-keyed maps and makes cache entry lifecycle management automatic via the `WeakMap` behavior. * **`prepare` function:** * Defined `setPointerEvent`, `addInteraction`, and `removeInteraction` methods directly on the `instance.__ngt__` object literal. This is a minor change for code consistency with other method definitions in the same object. 3. **`libs/core/src/lib/loader.ts` (`_injectLoader` function):** * Optimized the `effect` hook to reduce redundant processing. * The effect now compares the current normalized URLs with the previously processed ones. If the normalized URLs haven't changed (even if the input signal reference has), further processing (like re-evaluating promises and updating the output signal) is skipped. This avoids unnecessary work when input signals change identity but not effective content. Unit tests have been added for all these optimizations to ensure correctness and prevent regressions. These tests cover: * Correct sorting logic in `events.ts`. * Method consistency and notification throttling in `instance.ts`. * Conditional execution of loader logic in `loader.ts`. --- libs/core/src/lib/events.spec.ts | 273 +++++++++++++++++++++++++++++ libs/core/src/lib/events.ts | 34 +++- libs/core/src/lib/instance.spec.ts | 207 ++++++++++++++++++++++ libs/core/src/lib/instance.ts | 114 +++++------- libs/core/src/lib/loader.spec.ts | 130 ++++++++++++++ libs/core/src/lib/loader.ts | 35 +++- 6 files changed, 711 insertions(+), 82 deletions(-) create mode 100644 libs/core/src/lib/events.spec.ts create mode 100644 libs/core/src/lib/instance.spec.ts create mode 100644 libs/core/src/lib/loader.spec.ts diff --git a/libs/core/src/lib/events.spec.ts b/libs/core/src/lib/events.spec.ts new file mode 100644 index 00000000..f3cde3da --- /dev/null +++ b/libs/core/src/lib/events.spec.ts @@ -0,0 +1,273 @@ +import * as THREE from 'three';

This restores their original definition style, ensuring properties like non-enumerability are maintained as intended. 2. **`libs/core/src/lib/events.ts` (`intersect` function):** * The sorting mechanism for `raycastResults` has been updated to use a `WeakMap`. * Before sorting, a `WeakMap` is populated where keys are the `THREE.Intersection` objects and values are their calculated `priority` and `stateExists` status. * The sort comparator then uses this `WeakMap` to access these pre-calculated values. This approach avoids intermediate array mapping, potentially improving memory efficiency while still preventing redundant `getInstanceState` calls within the sort. 3. **Spec Files Removed:** * Deleted `libs/core/src/lib/events.spec.ts`. * Deleted `libs/core/src/lib/instance.spec.ts`. * Deleted `libs/core/src/lib/loader.spec.ts`. Unit tests will be handled separately as per feedback. The optimization for `libs/core/src/lib/loader.ts` (`_injectLoader` effect) from the previous set of changes remains in place. --- libs/core/src/lib/events.spec.ts | 273 ----------------------------- libs/core/src/lib/events.ts | 41 +++-- libs/core/src/lib/instance.spec.ts | 207 ---------------------- libs/core/src/lib/instance.ts | 91 ++++++---- libs/core/src/lib/loader.spec.ts | 130 -------------- 5 files changed, 78 insertions(+), 664 deletions(-) delete mode 100644 libs/core/src/lib/events.spec.ts delete mode 100644 libs/core/src/lib/instance.spec.ts delete mode 100644 libs/core/src/lib/loader.spec.ts diff --git a/libs/core/src/lib/events.spec.ts b/libs/core/src/lib/events.spec.ts deleted file mode 100644 index f3cde3da..00000000 --- a/libs/core/src/lib/events.spec.ts +++ /dev/null @@ -1,273 +0,0 @@ -import * as THREE from 'three';

This change also reinstates the `queueMicrotask`-based global cache clearing. The previous `WeakMap` implementation, while aimed at improving memory management, was found to cause regressions in scenarios where object identity for instances might not be stable, leading to incorrect notification throttling.

The function's signature has been updated to accept an optional `parentInstanceState`. When making recursive calls, the instance state of the current node (which is the parent in the next call) is now passed along. The initial call site in `attachThreeNodes` has also been updated to provide the already fetched parent's instance state. This change avoids repeatedly looking up the parent's instance state at each level of the recursion, which can lead to a performance improvement during scene graph manipulations, especially with deeper component trees. --- libs/core/src/lib/renderer/utils.ts | 14 +++++++++----- 1 file changed, 9 insertions(+), 5 deletions(-) diff --git a/libs/core/src/lib/renderer/utils.ts b/libs/core/src/lib/renderer/utils.ts index dc7b7ec6..29ad79ef 100644 --- a/libs/core/src/lib/renderer/utils.ts +++ b/libs/core/src/lib/renderer/utils.ts @@ -46,9 +46,13 @@ export function kebabToPascal(str: string): string { return pascalStr; } -function propagateStoreRecursively(node: NgtInstanceNode, parentNode: NgtInstanceNode) { +function propagateStoreRecursively( + node: NgtInstanceNode, + parentNode: NgtInstanceNode, + parentInstanceState?: NgtInstanceState, +) { const iS = getInstanceState(node); - const pIS = getInstanceState(parentNode); + const pIS = parentInstanceState || getInstanceState(parentNode); if (!iS || !pIS) return; @@ -69,7 +73,7 @@ function propagateStoreRecursively(node: NgtInstanceNode, parentNode: NgtInstanc // Recursively reassign the store for each child for (const child of children) { - propagateStoreRecursively(child, node); + propagateStoreRecursively(child, node, iS); } } } @@ -85,8 +89,8 @@ export function attachThreeNodes(parent: NgtInstanceNode, child: NgtInstanceNode // whether the child is added to the parent with parent.add() let added = false; - // propagate store recursively - propagateStoreRecursively(child, parent); + // propagate store recursively, passing the already fetched parent instance state + propagateStoreRecursively(child, parent, pIS); if (cIS.attach) { const attachProp = cIS.attach;
