The original M-A branch had an identity-rewrite force-push yesterday that orphaned the branch ancestry from main (zero common commits). GitHub auto-closed PR #39 because of the divergent ancestry. This commit recovers the content as a single squash applied onto current main, preserving all post-M-A merges (PR #40 editor onboarding, PR #47 claim rule, PR #48 star check). The work below is identical to what was committed across the 5 M-A tasks (T1-T5). Atomic-task SHAs preserved in the harness at .opencode/plans/2026-05-31-self-roadmap-m-a.md as historical reference. M-A T1: refactor(types) — delete 5 ghost IssueType enum values (UNNECESSARY_RERENDER, DEV_MODE_IN_PROD, DIRECT_STATE_MUTATION, DUPLICATE_KEY, EXTRA_DEP). Fan-out across 9 files chasing string refs in panel components + tabs + tests. Also adds SEARCH_REDUX to MessageType union (yesterday's CI fix folded in). M-A T2: fix(inject) — bound 3 leaky Sets (reportedEffectIssues, reportedExcessiveRerenders, reportedSlowRenders) via TTL Maps in periodicCleanup. Was Set, now Map with 5-min TTL eviction. M-A T3: ci(typecheck) — add typecheck + typecheck:node + bench npm scripts. CI workflow now runs typecheck (fail-fast, no continue-on-error) BEFORE build. Pre-existing tsc errors fixed (SEARCH_REDUX added to MessageType, dead navigationStartTime + NAVIGATION_GRACE_MS declarations removed). tsconfig.node.json tightened to match root strict mode. Closes #27. M-A T4: test(bench) — vitest-bench harness skeleton: - test/bench/detectors.bench.ts (1365-node synthetic tree walk at ~575K hz, no-op detector benchmark) - test/fixtures/bench-tree/SimpleList.tsx (100-element list fixture) - bench/baselines/.gitkeep + bench/results/.gitkeep M-A T5: refactor(inject) — extract cleanup-interval lifecycle helpers into src/inject/lifecycle.ts (89 LoC). First leaf module exiting the 3270-LoC IIFE god-file. Zero behavior change (controller pre-flight verified the existing code was already lazy-install). Plus: .gitignore fix — was 'node_modules*.tsbuildinfo' smushed on one line, now correctly two lines. Verification: - tsc --noEmit: ZERO errors - build: exit 0 - test:run: 29 pre-existing emoji failures + 141 passes - bench: exit 0 Part of self-roadmap H2 2026 milestone M-A. --- .github/workflows/ci.yml | 6 ++ .gitignore | 6 +- bench/baselines/.gitkeep | 0 bench/results/.gitkeep | 0 package.json | 5 +- src/__tests__/IssueCard.test.tsx | 2 +- src/__tests__/UIStateTab.test.tsx | 16 ++--- src/__tests__/debugging-scenarios.tsx | 4 +- src/inject/index.ts | 51 ++++++++------ src/inject/lifecycle.ts | 89 +++++++++++++++++++++++++ src/panel/Panel.tsx | 4 +- src/panel/components/IssueCard.tsx | 25 ------- src/panel/tabs/PerformanceTab.tsx | 2 +- src/panel/tabs/SideEffectsTab.tsx | 4 +- src/panel/tabs/UIStateTab.tsx | 2 - src/types/index.ts | 6 +- test/bench/detectors.bench.ts | 23 +++++++ test/fixtures/bench-tree/SimpleList.tsx | 15 +++++ tsconfig.node.json | 7 +- 19 files changed, 195 insertions(+), 72 deletions(-) create mode 100644 bench/baselines/.gitkeep create mode 100644 bench/results/.gitkeep create mode 100644 src/inject/lifecycle.ts create mode 100644 test/bench/detectors.bench.ts create mode 100644 test/fixtures/bench-tree/SimpleList.tsx diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 07a1ed5..d9842b7 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -23,6 +23,12 @@ jobs: - name: Install dependencies run: npm ci + - name: Type check (src) + run: npm run typecheck + + - name: Type check (node/vite) + run: npm run typecheck:node + - name: Build extension run: npm run build diff --git a/.gitignore b/.gitignore index 2fbf5c1..2328fed 100644 --- a/.gitignore +++ b/.gitignore @@ -3,4 +3,8 @@ dist .sisyphus .agent worker -node_modules \ No newline at end of file +node_modules +*.tsbuildinfo + +# macOS noise +.DS_Store diff --git a/bench/baselines/.gitkeep b/bench/baselines/.gitkeep new file mode 100644 index 0000000..e69de29 diff --git a/bench/results/.gitkeep b/bench/results/.gitkeep new file mode 100644 index 0000000..e69de29 diff --git a/package.json b/package.json index c30003c..4797b4c 100644 --- a/package.json +++ b/package.json @@ -38,7 +38,10 @@ "test": "vitest", "test:run": "vitest run", "test:coverage": "vitest run --coverage", - "fixture:basic:dev": "npm --prefix test/fixtures/basic run dev" + "fixture:basic:dev": "npm --prefix test/fixtures/basic run dev", + "typecheck": "tsc --noEmit", + "typecheck:node": "tsc -p tsconfig.node.json --noEmit", + "bench": "vitest bench --run" }, "devDependencies": { "@resvg/resvg-js": "^2.6.2", diff --git a/src/__tests__/IssueCard.test.tsx b/src/__tests__/IssueCard.test.tsx index 3aac3fd..a77022a 100644 --- a/src/__tests__/IssueCard.test.tsx +++ b/src/__tests__/IssueCard.test.tsx @@ -36,7 +36,7 @@ const mockWarningIssue: Issue = { const mockInfoIssue: Issue = { id: 'issue-3', - type: 'DEV_MODE_IN_PROD', + type: 'SLOW_RENDER', severity: 'info', component: 'App', message: 'React is running in development mode', diff --git a/src/__tests__/UIStateTab.test.tsx b/src/__tests__/UIStateTab.test.tsx index f118202..d731230 100644 --- a/src/__tests__/UIStateTab.test.tsx +++ b/src/__tests__/UIStateTab.test.tsx @@ -44,12 +44,11 @@ const mockUIIssues: Issue[] = [ }, { id: 'issue-3', - type: 'DIRECT_STATE_MUTATION', + type: 'MISSING_KEY', severity: 'error', component: 'Counter', - message: 'State object was mutated directly', - suggestion: 'Use setState with a new object or spread operator', - code: 'state.count++ // Wrong!\nsetState({ count: state.count + 1 }) // Correct', + message: 'Counter list items are missing key props', + suggestion: 'Add unique key prop to each counter item', timestamp: Date.now(), }, ];
