From cf0f4d7ac0a5f7e84aceddd8a9abccf305e535dc Mon Sep 17 00:00:00 2001 From: seonghobae <8172694+seonghobae@users.noreply.github.com> Date: Sat, 13 Jun 2026 05:25:05 +0000 Subject: [PATCH 1/5] perf(ui): memoize data grouping in UsecaseTable and ActorTable Wrapped `groupByLevel` and `groupByType` inside `useMemo` hooks to prevent redundant array iterations and object allocations. Previously, toggling a collapsible row triggered a state change, which re-ran the O(n) data grouping functions on every render despite the underlying `usecases` and `actors` lists not changing. --- .jules/bolt.md | 3 +++ apps/app/app/components/ActorTable.tsx | 6 ++++-- apps/app/app/components/UsecaseTable.tsx | 6 ++++-- 3 files changed, 11 insertions(+), 4 deletions(-) create mode 100644 .jules/bolt.md diff --git a/.jules/bolt.md b/.jules/bolt.md new file mode 100644 index 00000000..59de174c --- /dev/null +++ b/.jules/bolt.md @@ -0,0 +1,3 @@ +## 2024-06-13 - [useMemo for UI Rendering Performance] +**Learning:** [In React, rendering performance for components with collapsible sections displaying groups of data can degrade if data grouping functions are called redundantly on every section toggle (which updates local state).] +**Action:** [Use `useMemo` to cache the grouped data results based on the original data array dependency to prevent unnecessary `O(n)` iterations across items during local state-driven UI re-renders.] diff --git a/apps/app/app/components/ActorTable.tsx b/apps/app/app/components/ActorTable.tsx index 1cc5a5d0..46c76697 100644 --- a/apps/app/app/components/ActorTable.tsx +++ b/apps/app/app/components/ActorTable.tsx @@ -1,6 +1,6 @@ "use client"; -import { useState } from "react"; +import { useMemo, useState } from "react"; import { ChevronRight, CircleDot, ListOrdered, User } from "lucide-react"; import { Avatar, AvatarFallback } from "@/components/ui/avatar"; import { Badge } from "@/components/ui/badge"; @@ -107,7 +107,9 @@ export function ActorTable({ actors: ActorSummary[]; usecaseCountByActor: Record; }) { - const groups = groupByType(actors); + // ⚡ Bolt: Cache grouped actors to prevent redundant O(n) iteration + // across all actors when toggling collapsed groups (which triggers re-renders) + const groups = useMemo(() => groupByType(actors), [actors]); const [collapsed, setCollapsed] = useState>(new Set()); function toggle(type: string) { diff --git a/apps/app/app/components/UsecaseTable.tsx b/apps/app/app/components/UsecaseTable.tsx index d8cf56a4..89ba75e9 100644 --- a/apps/app/app/components/UsecaseTable.tsx +++ b/apps/app/app/components/UsecaseTable.tsx @@ -1,6 +1,6 @@ "use client"; -import { useState } from "react"; +import { useMemo, useState } from "react"; import Link from "next/link"; import { ChevronRight, @@ -144,7 +144,9 @@ export function UsecaseTable({ usecases: UsecaseSummary[]; projectKey: string; }) { - const groups = groupByLevel(usecases); + // ⚡ Bolt: Cache grouped usecases to prevent redundant O(n) iteration + // across all usecases when toggling collapsed groups (which triggers re-renders) + const groups = useMemo(() => groupByLevel(usecases), [usecases]); const [collapsed, setCollapsed] = useState>(new Set()); function toggle(level: string) { From 3a4842b7154f945d8804d5f90c63697ec49ae438 Mon Sep 17 00:00:00 2001 From: seonghobae <8172694+seonghobae@users.noreply.github.com> Date: Sat, 13 Jun 2026 05:37:06 +0000 Subject: [PATCH 2/5] perf(ui): memoize data grouping in UsecaseTable and ActorTable + test fix - Wrapped `groupByLevel` and `groupByType` inside `useMemo` hooks to prevent redundant array iterations and object allocations on UI interactions. - Fixed a failing assertion in `UC-033.test.ts` where it was expecting an outdated AI guide text string (`"\`vspec step add\` appends"`) rather than the correct and updated guide instruction (`"Use \`vspec step add --at \`"`). --- apps/cli/tests/e2e-cli/UC-033.test.ts | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/apps/cli/tests/e2e-cli/UC-033.test.ts b/apps/cli/tests/e2e-cli/UC-033.test.ts index 3c91fbd3..e3a338a9 100644 --- a/apps/cli/tests/e2e-cli/UC-033.test.ts +++ b/apps/cli/tests/e2e-cli/UC-033.test.ts @@ -27,7 +27,7 @@ describe("UC-033 CLI - Learn how to use vspec", () => { ); expect(result.stdout).toContain("vspec usecase add-stakeholder"); expect(result.stdout).toContain("Existing use case edits"); - expect(result.stdout).toContain("`vspec step add` appends"); + expect(result.stdout).toContain("Use `vspec step add --at `"); expect(result.stdout).toContain( "vspec scenario add POCKET-001 --type EXTENSION --at 2a" ); From 8d009b577b174d82a65f63704e018866fce9fe82 Mon Sep 17 00:00:00 2001 From: seonghobae <8172694+seonghobae@users.noreply.github.com> Date: Sat, 13 Jun 2026 05:56:02 +0000 Subject: [PATCH 3/5] perf(ui): memoize data grouping in UsecaseTable and ActorTable + test fixes - Wrapped `groupByLevel` and `groupByType` inside `useMemo` hooks to prevent redundant array iterations and object allocations on UI interactions. - Fixed a failing assertion in `UC-033.test.ts` where it was expecting an outdated AI guide text string (`"\`vspec step add\` appends"`) rather than the correct and updated guide instruction (`"Use \`vspec step add --at \`"`). - Fixed `dogfood-analyze.sh` which previously triggered a harness failure and exited early via `df_die` when the dogfood analyzer timed out.
