It supports severity, auto-dismiss, manual dismiss, and stacking with CSS animations. +2. **EventSource 401/429 detection**: Native `EventSource` does not expose HTTP status codes. Implemented a `probeEventStreamStatus()` helper that does a short `fetch()` to the SSE endpoint with `AbortController` timeout to detect 401/429 before reconnecting. +3. **Badge color CSS classes**: The existing `session-card.tsx` used raw color strings ("green", "yellow", etc.) as CSS class names, but no corresponding CSS classes existed. Added explicit `.status-badge.starting`, `.status-badge.probing`, and `.status-badge.unhealthy` rules to `styles.css`. +4. **Tunnel health removal**: The 30s polling loop in `instance-list.tsx` was the source of `healthStatus` state used for "tunnel error" badges. After removing polling, tunnel-specific health data is no longer available in real time; instances now rely on SSE `status` transitions (e.g., `unhealthy`). The tunnel error badge was removed from `instance-list.tsx` as redundant with the status badge. +5. **App.tsx vs app-shell.tsx**: This codebase has no `App.tsx`; `AppShell` in `app-shell.tsx` is the layout component that wraps all authenticated routes. Providers were mounted there instead. + +--- + +## PR Boundary + +This PR includes the complete frontend UI for container monitoring and notifications: +- SSE client hook with reconnect backoff +- Custom toast notification system +- Event provider context +- Real-time status badge updates +- Polling removal from instance list + +The next PR (PR-3) should cover: +- Integration tests for lifecycle event flow +- E2E tests for container start → toast and crash detection +- Performance tuning (connection limits, queue bounds, jitter) +- Documentation updates +- Final cleanup and regression validation diff --git a/openspec/changes/container-monitoring-notifications/apply-progress.md b/openspec/changes/container-monitoring-notifications/apply-progress.md index 2f98775..66d77e7 100644 --- a/openspec/changes/container-monitoring-notifications/apply-progress.md +++ b/openspec/changes/container-monitoring-notifications/apply-progress.md @@ -82,11 +82,102 @@ All checks passed! 3. **Delete audit row**: The FK `ON DELETE CASCADE` on `instance_events.instance_id` means the audit row for `instance.deleted` cannot survive deletion. The row is inserted before `session.delete(instance)` and is cascade-deleted on commit. The event bus publication still occurs. 4. **SQLite test compatibility**: Used `JSON` instead of `JSONB` in the SQLAlchemy model to maintain SQLite test compatibility. The migration uses `sa.JSON()` which maps appropriately. -## Remaining Tasks (for PR-2 / PR-3) +## Remaining Tasks (for PR-3) -- Frontend `useEvents()` hook, `ToastProvider`, `toast-rules.ts` -- Frontend badge real-time updates + polling removal - Integration tests for SSE endpoint (MON-PR1-012) - Integration tests for lifecycle hooks - E2E tests - Performance tuning and documentation + +--- + +# PR-2 Apply Progress: Frontend UI for Container Monitoring & Notifications + +## TDD Cycle Evidence + +### useEvents Hook (MON-PR2-001 + MON-PR2-002 + MON-PR2-006) +| Cycle | Action | Evidence | +|-------|--------|----------| +| RED | Wrote `use-events.test.ts` with mocks for non-existent `api/events.ts` and `hooks/use-events.ts` | `vitest` collection error: `Cannot find module '../api/events'` | +| GREEN | Implemented `types/events.ts`, `api/events.ts`, and `hooks/use-events.ts` with SSE connect + reconnect backoff | `vitest run src/hooks/use-events.test.ts` → 7 passed | +| REFACTOR | Extracted `probeEventStreamStatus` into `api/events.ts`; added `isMountedRef` guard to prevent state updates after unmount | Tests still pass | +| TRIANGULATE | Added 401 redirect test and 429 penalty test using `probeEventStreamStatus` | Both pass | + +### Toast Rules (MON-PR2-003 + MON-PR2-007) +| Cycle | Action | Evidence | +|-------|--------|----------| +| RED | Wrote `toast-rules.test.ts` mocking `../state/toast` | `vitest` collection error: `Cannot find module '../state/toast'` | +| GREEN | Implemented `state/toast.tsx` (custom toast system) and `components/toast-rules.ts` | `vitest run src/components/toast-rules.test.ts` → 7 passed | +| TRIANGULATE | Added deduplication tests (within 1s and after 1s) | Tests pass | + +### EventProvider + Integration (MON-PR2-004 + MON-PR2-005 + MON-PR2-007) +| Cycle | Action | Evidence | +|-------|--------|----------| +| RED | Attempted to mount `` in `app-shell.tsx` before component existed | Build error: `Cannot find module '../state/toast'` | +| GREEN | Created `state/events.tsx`, `components/event-toast-bridge.tsx`, and integrated all providers into `app-shell.tsx` | `tsc --noEmit` clean; app renders in tests | + +## Completed Tasks + +- [x] MON-PR2-001: `useEvents()` SSE hook with reconnect backoff (`apps/web/src/hooks/use-events.ts`) +- [x] MON-PR2-002: `events.ts` API client — EventSource wrapper + probe helper (`apps/web/src/api/events.ts`) +- [x] MON-PR2-003: Custom `Toast` system with severity, auto-dismiss, manual dismiss (`apps/web/src/state/toast.tsx`) +- [x] MON-PR2-004: `ToastContainer` that manages toast queue + stacking + CSS animations +- [x] MON-PR2-005: `EventProvider` context — wraps app, provides shared event stream +- [x] MON-PR2-006: Real-time status badge updates — replaced 30s polling in `instance-list.tsx` with SSE-driven updates +- [x] MON-PR2-007: Integrated into `app-shell.tsx` — mounts `ToastProvider` + `EventProvider` + `EventToastBridge` +- [x] MON-PR2-008: Frontend tests for `useEvents` (7 tests) and toast rules (7 tests) + +## Files Changed + +### New Files +- `apps/web/src/types/events.ts` +- `apps/web/src/api/events.ts` +- `apps/web/src/hooks/use-events.ts` +- `apps/web/src/hooks/use-events.test.ts` +- `apps/web/src/components/toast-rules.ts` +- `apps/web/src/components/toast-rules.test.ts` +- `apps/web/src/state/toast.tsx` +- `apps/web/src/state/events.tsx` +- `apps/web/src/components/event-toast-bridge.tsx` + +### Modified Files +- `apps/web/src/components/app-shell.tsx` — mount providers +- `apps/web/src/components/instance-list.tsx` — remove 30s polling, add SSE status updates, add 60s refresh +- `apps/web/src/components/session-card.tsx` — update badge color mapping +- `apps/web/src/styles.css` — add status-badge and toast animation styles + +## Test Evidence + +```bash +# New frontend unit tests — all pass +$ cd apps/web && npx vitest run src/hooks/use-events.test.ts src/components/toast-rules.test.ts +14 passed + +# Regression check on related pages/components +$ cd apps/web && npx vitest run src/hooks/use-events.test.ts src/components/toast-rules.test.ts src/pages/dashboard.test.tsx src/components/terminal-session-tabs.test.tsx src/components/protected-route.test.tsx +25 passed + +# TypeScript check +$ cd apps/web && npx tsc --noEmit +# Exit code: 0 + +# Lint on new/modified files +$ cd apps/web && npx eslint --ext ts,tsx --report-unused-disable-directives --max-warnings 0 +# Exit code: 0 +``` + +## Deviation from Design + +1. **No sonner dependency**: The orchestrator explicitly instructed not to install `sonner` because `npm install` hangs in this environment.
