# UI/UX Audit — Nielsen's 10 Heuristics

**Scope:** Live deployment at `http://100.108.208.56:8082/`, React frontend at `frontend/src/`, complementing the existing docs/repo reviews in this folder.
**Method:** Playwright (system Chromium) navigated 20 routes/viewports; findings triangulated against source code with `file:line` references.
**Screenshots:** `/tmp/opencode/mp-review/screenshots/` (20 PNGs referenced inline).
**Severity scale:** **P0 (blocker)** — broken core flow · **P1 (major)** — wrong or misleading · **P2 (minor)** — polish/aa.

---

## Executive summary

The app looks polished on the surface (Tailwind palette, clean cards, working toasts, working focus rings), but a live walkthrough surfaces **multiple silent failures and three outright broken data-rendering bugs**. The most damaging issues are not visual — they are *unmistakable data inconsistencies* the user is expected to read and act on (`$N/A per serving`, blank `lb Pork Chops` rows, hidden empty meal slots on mobile, snake_case aisle labels). They erode trust faster than a missing button.

**Top 5 to fix first** (P0):

1. **Meal detail ingredients render without quantities** (field-name bug, `MealDetail.tsx:249-250`) — a core function of the page is unreadable.
2. **`$N/A per serving`** displayed literally (`MealDetail.tsx:191`).
3. **Recipe detail ingredients collapse unit and name** (`RecipeDetail.tsx:161` — `2 canBlack Beans`).
4. **`/recommended` returns a blank page** (missing route + no 404 catch-all in `App.tsx`).
5. **Mobile dashboard hides empty meal slots** (`Dashboard.tsx:164,219` — users on phones cannot *plan* meals, only view them).

> **Sprint 1 status (commit `f3e4a44`, deployed by user 2026-06-02):** Items 1, 2, 3, 4, 5 all addressed in the frontend source. Live at `100.108.208.56:8082/`. Verification screenshots in `/tmp/opencode/mp-review/screenshots/fix-sprint1/`.
>
> **Sprint 2 status (commit `ccc70aa`, deploy helper `f5fb755`):** All six P1s plus the S3.3 mobile shopping-list stat-grid fix are addressed in source.
> - **B6** Dashboard `MealCard` title: `truncate` → `line-clamp-2`; image shrinks to 40×40 on `<md` to give title more room.
> - **B7** `MealDetail` hero: title/description no longer overlap; description stripped of spoonacular SEO copy via `lib/utils.cleanDescription`; raw text moved to a "Notes from source" disclosure.
> - **B8** `Pantry` aisle/unit: free-text → canonical `Select` from `PANTRY_AISLES` enum (`types/index.ts`). `Ingredient name` field now marked `*` required. Backend migration `0015_normalize_pantry_aisles.py` normalizes `ingredient.aisle` and `grocery_item.aisle` to canonical labels. Dry-run SQL helper at `backend/scripts/dry_run_aisle_migration.sql`.
> - **B9** `ShoppingList` aisle section headers now human-readable via `AISLE_LABEL` map; falls back to raw key for unknown values.
> - **B10** Mobile pantry table: right-edge white-to-transparent gradient overlay hints at horizontal overflow; container has `role="region"` + descriptive `aria-label`.
> - **B11** Recipes filters: refactored to `pending`/`applied` state with explicit Apply / Reset buttons. `Filters` button shows active-count chip when filters are set. Wrapped in `role="region" aria-label="Filters"`.
> - **S3.3** Shopping list stat cards: now `grid-cols-3` on all viewports with compact mobile sizing.
>
> Deployment commands (run on the deployment host — DB is in a container, no host psql needed):
> ```bash
> cd ~/MealPlanner
> git pull
>
> # Optional: persistent backup of aisle values BEFORE the migration
> docker compose exec -T db psql -U mealplanner -d mealplanner \
>   -f /dev/stdin < backend/scripts/persist_aisle_backup.sql
>
> # Dry-run preview (no writes)
> docker compose exec -T db psql -U mealplanner -d mealplanner \
>   -f /dev/stdin < backend/scripts/dry_run_aisle_migration.sql
>
> # Apply the migration
> docker compose exec backend alembic upgrade head
>
> # Rebuild & restart frontend
> docker compose -f docker-compose.yml up -d --build frontend
> ```

> **Sprint 3 status (commit pending, ready for deploy):** All P2s plus the a11y sweep.
> - **B12** Native `confirm()` deleted for both delete sites. `lib/toast.tsx` (renamed from `.ts` for JSX) gains a new `showToast.undo(message, onUndo, ms=5000)` helper. `Dashboard.handleDelete` captures the full item, deletes, then surfaces an Undo toast that re-fires `generateItem(planId, dayOfWeek, mealType)` to refill the slot. `Pantry.handleRemove` is fully reversible: re-adds via `pantry.add` with the original `ingredient_id`/`quantity`/`unit`. Per-row loading state via new `removeId` state.
> - **B13** `Navigation` link text gets `whitespace-nowrap`; padding reduced to `px-2 sm:px-3` so all 4 links fit on one line down to ~360 px.
> - **S3.4** Confirmed `ErrorBoundary` is already mounted at `App.tsx:42` (verified `components/ErrorBoundary.tsx`).
> - **S3.5** A11y sweep: `<nav aria-label="Primary">`, `aria-current="page"` on the active nav link, `<main id="main-content">` for skip-link targets, `Badge` component extended with optional `icon` and `aria-label` props. Approval-status Badge on the meal card now passes `aria-label="Approval status: approved"` etc.
> - **S3.3** Mobile shopping-list stat cards already done in Sprint 2 (3-col grid with compact mobile sizing).
>
> Deploy:
> ```bash
> cd ~/MealPlanner
> git pull
> docker compose -f docker-compose.yml up -d --build frontend
> ```

## Findings mapped to Nielsen's 10 Heuristics

### H1 · Visibility of system status — *Partial*

✅ **Works well**
- Toasts (`react-hot-toast`) for generate/delete are top-right and persist.
- Status badges on the dashboard (e.g. `$206.21` total) update reactively.
- Loading skeletons render on data fetch.

⚠️ **Gaps**
- **Filters (P2).** Active filter count is not shown when the filter panel is collapsed (`Recipes.tsx:99` area, `16-recipes-filters-open.png`). User has no way to know a filter is on.
- **Pantry search (P2).** No "X of N results" indicator.
- **Sync status (P2).** When a meal is being generated, no spinner on the slot itself — only the global toast after success.

**Fix:** Render an `activeFilters.length` chip on the Filters button; add a small "Searching…" indicator inside the Pantry search input.

---

### H2 · Match between system and the real world — *Multiple violations*

🚨 **P1 · Snake-case aisle labels on Shopping List** (`page-shopping-list.png`)
- Sections display `meat_seafood`, `produce`, `pantry`, `dairy`.
- Fix: human-readable map in `ShoppingList.tsx`:
  ```ts
  const AISLE_LABEL: Record<string,string> = {
    meat_seafood: 'Meat & Seafood', produce: 'Produce',
    pantry: 'Pantry', dairy: 'Dairy & Eggs',
  };
  ```

🚨 **P1 · `$N/A per serving`** (`MealDetail.tsx:191`, `14-meal-detail.png`)
- `${item.estimated_cost?.toFixed(2) || 'N/A'}` renders `$N/A` literally because the `$` is outside the conditional.
- Fix:
  ```tsx
  {item.estimated_cost != null
    ? `$${item.estimated_cost.toFixed(2)} per serving`
    : 'No price estimate yet'}
  ```

🚨 **P0 · Ingredients render without quantities on the Meal page** (`MealDetail.tsx:249-252`, `14-meal-detail.png`)
- Code reads `ing.quantity` / `ing.unit` but the backend returns `qty` (per `RecipeDetail.tsx:161` working correctly). Result: `lb Pork Chops, Bone-In` instead of `1 lb Pork Chops, Bone-In`.
- Fix: rename both fields to a single canonical name (recommend `qty` to match backend), or apply a compatibility shim:
  ```tsx
  const qty = ing.qty ?? ing.quantity;
  const unit = ing.unit ?? ing.unit;
  ```
  and update the type definition.

🚨 **P1 · Spoonacular marketing copy leaks into meal description** (`14-meal-detail.png`)
- The meal page description includes: *"Featured In Group could be just the gluten free, dairy free, and ketogenic recipe you've been looking for… users who liked this recipe also liked Baked Chicken In Avocado Boat…"*
- Fix: backend `Meal.description` should be truncated to ~280 chars on import, with a regex strip of the "Featured In Group…" / "users who liked…" boilerplate. Alternatively, render `description.split('. ').slice(0,2).join('. ')+'.'` on the frontend with a `line-clamp-3` parent.

🚨 **P1 · Hero title overlaps description** (`MealDetail.tsx:168-197`, `14-meal-detail.png`)
- Long description text (no `line-clamp`) sits over the absolute-positioned title block, making the title literally unreadable.
- Fix: add `line-clamp-3` and `max-w-2xl` on the description; ensure the title is in normal flow (not absolute) on this view.

---

### H3 · User control and freedom — *Partial*

✅ **Works**
- Back links on Recipe and Meal detail pages.
- Drag-and-drop on dashboard (via `@hello-pangea/dnd`) is reversible.

⚠️ **Gaps**
- **P1 · Native `confirm()` dialogs for delete** — jarring, breaks visual continuity. Replace with an inline "Undo" toast (e.g. `react-hot-toast` with a 5s undo that re-fires the create query). See `Dashboard.tsx` meal delete and `Pantry.tsx` row delete.
- **P2 · No keyboard shortcut to focus search** on Recipes/Pantry/Shopping List. Convention is `/` or `Cmd+K`.
- **P2 · Filters have no Reset button** (`16-recipes-filters-open.png`).

---

### H4 · Consistency and standards — *Multiple violations*

🚨 **P1 · Aisle casing inconsistency in Pantry** (`page-pantry.png`, `Pantry.tsx:200`)
- Rows show `Canned Goods`, `Pantry`, `pantry`, `Produce`, `Freezer` — all derived from free-text input. Aisle should be a fixed enum.
- Fix: replace the free-text input with a `<select>` populated from `['Produce','Meat & Seafood','Dairy & Eggs','Pantry','Frozen','Bakery','Beverages','Spices','Other']`. Migrate existing rows via a one-off script that lowercases + maps.

🚨 **P1 · `qty` vs `quantity` field mismatch** between Recipe and Meal detail (covered under H2). The shared `Ingredient` type should have one canonical field.

⚠️ **P2 · Aisle filter pill on dashboard Shopping List card** is uppercase by Tailwind class; the rest of the app uses sentence case.

⚠️ **P2 · Mixed icon set** — `lucide-react` everywhere except a few hand-rolled SVGs in the dashboard's empty state.

---

### H5 · Error prevention — *Violations*

🚨 **P1 · Add Pantry Item form has no required markers and no validation** (`17-pantry-add-item.png`, `Pantry.tsx:~180-220`)
- "Add" button looks pre-disabled (light blue) but the user has no idea *why*. No `*` indicator on the required Ingredient Name field, no inline error, no disabled-until-valid logic explained.
- Fix: add `<span className="text-danger">*</span>` to required field labels; use `aria-describedby` to attach an inline help text; show an inline error on submit fail (e.g. *duplicate item*).

⚠️ **P2 · Filters apply immediately on change** — user can lose their current result set by accidently nudging "Max time". Add explicit Apply (or debounce 400 ms with a clear "Applying…" indicator).

⚠️ **P2 · Meal generate (Generate button) has no confirmation** for the current week — clicking accidentally overwrites. A `confirm()` for destructive regenerate is acceptable; better: a small "Replace existing?" toggle.

---

### H6 · Recognition rather than recall — *Partial*

✅ **Works**
- Recipe cards show tags (cuisine, diet) and quick stats.
- Status badges (Approved, etc.) are color-coded consistently.

⚠️ **Gaps**
- **P2 · No breadcrumbs** on detail pages. From `/meals/f28…` the user cannot see "Meal Plan › Pork Stir-Fry" without remembering.
- **P2 · No active filter chips** on the Recipes page — when filters are collapsed, user has no visible reminder of what's on (see H1).
- **P2 · Empty Pantry state** has no illustration or "Add your first item" primary CTA; just a blank table.

---

### H7 · Flexibility and efficiency of use — *Weak*

🚨 **P1 · No bulk actions on Shopping List or Pantry** (`page-shopping-list.png`, `page-pantry.png`)
- Adding common items (salt, pepper, oil) is one-by-one. Add a "Multi-select" mode with a header that says `2 selected · [Delete] [Move aisle]`.

⚠️ **P2 · No keyboard shortcuts.**
- `/` focus search
- `g p` go to Pantry
- `g s` go to Shopping List
- `n m` new meal
- A small `useShortcuts` hook in `App.tsx` plus a "?" help modal would cover this.

⚠️ **P2 · Generate button regenerates one slot at a time**. A "Plan whole week" button would be a huge efficiency win for a meal planner.

⚠️ **P2 · No persistent week selector** in the URL — back/forward loses the week you're viewing.

---

### H8 · Aesthetic and minimalist design — *Mostly good, with one outlier*

✅ **Works**
- Palette is restrained (surface, primary, warning, success, danger).
- Card hierarchy is clear on Recipes grid.

🚨 **P1 · Meal detail hero is chaotic** (`14-meal-detail.png`)
- Title, badge, description, and metadata all compete; title is unreadable due to the overlap (H2). Long marketing copy adds noise. Tighten to: title → single-line subtitle (cuisine · 25 min · 4 servings) → 1-2 sentence description → CTA. Move the long marketing body into a "Notes from source" collapsible at the bottom.

⚠️ **P2 · Stat cards on Shopping List stack 3 full-width tiles on mobile** (`mobile-shopping-list.png`) — heavy vertical scroll. Consider a 3-up compact layout (icon + value, label below) for `< sm`.

⚠️ **P2 · Mobile nav wraps "Shopping List" onto a second line** (`04-dashboard-mobile.png`). Add `whitespace-nowrap` to nav links.

---

### H9 · Help users recognize, diagnose, and recover from errors — *Violations*

🚨 **P0 · `/recommended` is a blank page** (`page-recommended.png`, `13-recommended-broken.png`, `mobile-recommended.png`)
- The Navigation links do not point to `/recommended` (they correctly point to `/recipes/recommended`), but the URL is referenced in user-facing strings somewhere (most likely an email link or share URL) and resolves to an empty React Router outlet.
- The "Recommended" link in the Recipes header also has a known link to `/recipes/recommended` which works.
- Fix: add a `*` catch-all route in `App.tsx` rendering a friendly `NotFound` component with a "Back to dashboard" CTA; optionally also alias `/recommended → /recipes/recommended` via `<Navigate replace />`.

🚨 **P1 · No error boundary** — if a single component throws (e.g. an ingredient with `null.qty`), the whole page goes blank. Add a top-level `<ErrorBoundary>` in `App.tsx` that shows "Something went wrong. [Reload] [Report]".

⚠️ **P2 · Recipes with no image show a generic cooking-pot icon silently.** Add a `title="Image not available"` and consider a "Report missing image" link.

⚠️ **P2 · 401/403/500 errors from the API are not surfaced as user-readable toasts.** Hook into the `react-query` `onError` global handler.

---

### H10 · Help and documentation — *Missing*

🚨 **P1 · No onboarding for first-time users** — empty dashboard, empty pantry, empty shopping list with no guidance.
- Add a one-time tour (e.g. `react-joyride`) or just 3 inline hint cards on the dashboard: *1. Add items to your pantry · 2. Generate this week's meals · 3. Review the shopping list*.
- Add a "?" icon in the nav that opens a Help modal with a quick-start, FAQ, and a link to `docs/`.

⚠️ **P2 · No tooltips on advanced filter labels** (Max time, Max spice, Max calories) — units and ranges are not obvious. Use `aria-describedby` + a small "?" popover.

⚠️ **P2 · Print List button is hidden behind the page scroll** on mobile. Make it sticky on `lg:` viewports at minimum.

---

## Accessibility (WCAG 2.1 AA quick scan)

- **P1 · `aria-current="page"`** missing on the active nav link. Add it in `Navigation.tsx`.
- **P1 · Recipes filter panel** opens inline but is not announced as a region. Add `role="region"` `aria-label="Filters"`.
- **P1 · Modal/dialogs** (none observed, but recommend `focus-trap-react` whenever added).
- **P2 · Color-only signals** — "Approved" badge relies on green alone; add an icon or `aria-label="Approved"`.
- **P2 · Touch targets** — Generate buttons in empty slots are < 44 px tall on mobile. Bump to `min-h-11`.
