# React Performance Audit
|
|
|
|
Status: in progress
|
|
Started: 2026-05-29
|
|
Base commit: `b7fe967780` (`origin/main`, release v1.4.35)
|
|
|
|
## Goal
|
|
|
|
Scan the full React surface for `$perf` and `$react-useeffect` issues, keep coverage evidence here, and land the fixes as many small PRs with explicit merge-risk notes.
|
|
|
|
This document is the audit ledger. A section is not considered fully scanned until it has:
|
|
|
|
1. File inventory checked from the current worktree.
|
|
2. `useEffect` / `useLayoutEffect` / `useInsertionEffect` sites classified.
|
|
3. Perf-sensitive patterns checked: timers, subscriptions, observers, `JSON.stringify`, storage writes, polling, broad store subscriptions, large list rendering, and render-time derived state.
|
|
4. Each suspicious site dispositioned as "no change", "needs PR", or "covered by PR".
|
|
5. Merge risk recorded for every PR candidate.
|
|
|
|
## Scope
|
|
|
|
React hook call scan uses all repo `*.ts` and `*.tsx` files, then narrows to actual AST hook calls. The React Effect surface found on 2026-05-29 is:
|
|
|
|
- `src/renderer/src/**`
|
|
- `mobile/app/**`
|
|
- `mobile/src/**`
|
|
- `mobile/packages/expo-two-way-audio/src/hooks.ts`
|
|
|
|
Comment-only mentions outside those paths were ignored.

Initial inventory:

|
| Metric | Count |
|
|
| --------------------------------------------------- | ----: |
|
|
| Repo `*.ts` / `*.tsx` files | 3,011 |
|
|
| Files with real Effect hook calls | 285 |
|
|
| Effect hook call sites | 970 |
|
|
| `useLayoutEffect` / `useInsertionEffect` call sites | 44 |
|
|
| Empty dependency arrays | 111 |
|
|
| Effects with cleanup returns | 472 |
|
|
| Effects with subscription/listener/observer shape | 170 |
|
|
| Effects with timer or animation-frame shape | 128 |
|
|
| Effects with `JSON.stringify` shape | 2 |
|
|
| Set-state-shaped Effects needing manual review | 270 |
|
|
| `useMemo` call sites in React scope | 633 |
|
|
| `useCallback` call sites in React scope | 1,415 |
|
|
| `useSyncExternalStore` call sites in React scope | 8 |
|
|
|

## Merge Risk Scale
|
|
|
|
| Risk | Criteria | Required verification |
|
|
| ------ | --------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------- |
|
|
| Low | Isolated local UI state, no persistence, no IPC, no terminal/browser/source-control behavior. | Targeted unit test if available plus `pnpm run typecheck:web`. |
|
|
| Medium | Settings, editor UI, mobile local UI, or state persisted per workspace but no transport protocol changes. | Targeted tests plus manual interaction or focused Playwright/Electron check when UI behavior changes. |
|
|
| High | Terminal/PTY, browser webview, source control, mobile remote-client, SSH, polling, persistence, or provider behavior. | Targeted tests, `pnpm run typecheck:web`, and Electron or mobile/manual parity evidence as appropriate. |
