# PWA Implementation Review

## Critical Issues

**1. Cache-first strategy serves stale content indefinitely** — `sw.js:44-46`
The fetch handler returns cached responses *before* checking the network. Once a page is cached, users will never see updates until the SW itself changes and activates. For a dynamic marketplace app, this is a serious bug — users could see stale job listings, old prices, or outdated hire statuses.

**2. Service worker caches all GET requests indiscriminately** — `sw.js:48-60`
Every successful `type: 'basic'` fetch is cached, including API responses (`/api/*`), auth tokens, Supabase queries, and Stripe endpoints. This means sensitive authenticated data gets persisted in the browser cache with no expiry. This is both a **security risk** and a **correctness bug**.

**3. `dangerouslySetInnerHTML` for SW registration** — `layout.tsx:74-89`
Inline script via `dangerouslySetInnerHTML` bypasses CSP and React's XSS protections. While the content is static here, this is the wrong pattern. A separate `/sw-register.js` file or Next.js `<Script>` component is the correct approach.

**4. SVG icons declared with fixed pixel sizes** — `manifest.json:12-13,17-18`
SVGs are resolution-independent but the manifest declares them as `192x192` and `512x512`. Browsers may reject these or not treat them as the correct size. Chrome specifically requires **PNG icons** for installability — SVG-only manifests will fail the "Add to Home Screen" prompt on most Android devices.

## Medium Issues

**5. `"purpose": "any maskable"` on the same icon** — `manifest.json:15`
Combining `any` and `maskable` on one icon entry is deprecated/unreliable. Maskable icons need a safe zone padding that looks wrong when rendered as `any`. These should be separate entries with separate assets.

**6. No `/offline` page exists** — `sw.js:68`
The SW falls back to `caches.match('/offline')` on navigation failure, but there's no evidence of an `/offline` route in the app. This will silently return `undefined`, giving users a blank page or browser error when offline.

**7. Duplicate meta tags** — `layout.tsx:15-39` vs `layout.tsx:56-67`
The `metadata` export already generates `manifest`, `theme-color`, `apple-mobile-web-app-capable`, etc. The manual `<head>` tags duplicate all of them, resulting in double meta tags in the rendered HTML. Next.js metadata API should be the single source.

**8. `manifest.json` header marked `immutable`** — `next.config.ts:12`
`Cache-Control: immutable` tells browsers the content will never change at this URL. If you update the manifest (new icons, name change), users won't see updates for up to an hour, and some browsers may cache even longer.

**9. `maximumScale: 1` blocks pinch-to-zoom** — `layout.tsx:45`
This is an **accessibility violation** (WCAG 1.4.4). Users with low vision cannot zoom. Many app stores and audits flag this.

## Minor Issues

**10. Comment says "compiled by next-pwa" but next-pwa is not installed** — `sw.js:2`
Misleading comment. This is a hand-written SW served statically.

**11. `console.log` statements in production SW** — `sw.js:16,29` and `layout.tsx:80,83`
Debug logging left in production code.

**12. Empty `screenshots` array** — `manifest.json:34`
Harmless but unnecessary. Either add screenshots or remove the key.

**13. `lang: "en"` in manifest vs `lang="en-AU"` in HTML** — `manifest.json:31` vs `layout.tsx:55`
Inconsistent locale. Should be `en-AU` everywhere per the spec's Australian English requirement.

**14. No `Service-Worker-Allowed` header** — `next.config.ts`
The SW scope defaults to its directory (`/`), which works here, but an explicit header is a good practice for clarity.

## Recommendations

- Replace the cache-first strategy with **network-first** for API/dynamic routes, and cache-first only for static assets (images, fonts, CSS/JS).
- **Exclude** `/api/*`, Supabase URLs, and Stripe URLs from caching entirely.
- Add PNG icons (required for Chrome installability).
- Create an actual `/offline` page.
- Remove the `dangerouslySetInnerHTML` script block; use Next.js `<Script strategy="afterInteractive">` or a separate file.
- Remove all duplicate `<head>` tags — rely solely on the `metadata` export.
- Remove `maximumScale: 1`.

## Quality Score: 3/10

The implementation has the basic shape of a PWA but contains critical bugs that would cause stale data, cache sensitive API responses, and fail Chrome's installability check. The service worker caching strategy is unsuitable for a dynamic marketplace. The duplicate meta tags and misleading comments indicate this was assembled hastily without testing.
